  A living wall is a vertically built structure intentionally covered with vegetation, it is also referred to as a green wall and for good reason. Not only does a vertical garden on an otherwise blank wall look extremely attractive, but there are huge environmental and sustainable advantages to be had too. With the addition of a green wall on a property, private or commercial, the heating and cooling bills can be reduced; it adds thermal benefits to a building, being the most natural form of cladding and aids in reducing urban temperature as well as pollution.
A green wall is an excellent noise insulator, reputedly to absorb over 40% more sound than a conventional building facade, ensuring a quieter environment at home or the office. A sense of well being is created, a positive effect on how the people feel, spirits are lifted, increased happiness and improved mental health, these are all benefits from vertical gardening. There are living wall modular systems that are available in a kit form to suit the vertical space available and budget. A drip irrigation system should be installed that will be connected to the mains water supply. It is an excellent opportunity to enhance biodiversity by increasing more plant life into an area, other than at ground level only. The chosen plants can be ones that are attractive to bees and specific habitat boxes can be incorporated within the structure that will provide refuge for a number of species such as butterflies, ladybirds and lacewings. A vertical garden can bring nature to an urban environment and whilst doing so improving the health of the people. With regards to plant selection, this depends on the aspect of the wall and the local climate unique to the area. There are, however, a huge variety of plants that can be used from annuals, perennials, succulents and even edibles. Spring is a good time to plant as the young plants will establish and grow together and it is important to have a year round interest, thus, incorporate plants with shape, form and colour of foliage as well as flowers. There are immense benefits to be had from a living wall, if space is limited at ground level, then why not consider growing vertically? It will be greatly appreciated by the people that use the building, people that are passing by and the biodiversity it creates will be appreciated too by nature.

 Plants which possess silver foliage can compliment a garden in many different ways, they provide a distinct contrast planted alongside green foliage and they can provide an all year round interest, brightening up an otherwise lacklustre area of the garden. But, it is not only a dull area that can benefit from the addition of a glaucous colour, a great attribute of silver/grey foliage is the ability to reflect sunlight and conserve water, this is enhanced by the hairy type foliage or a waxy texture of the leaves which many possess.
Many of theses plants are native to hot and dry areas and therefore drought tolerant, requiring low maintenance and will perform well in a full sun area of the garden with well drained soil. Silver foliage adds elegance and a cool sophistication to the garden and can be found on large trees down to small ground cover shrubs and perennials. Eucalyptus, the snow gum tree, is one of the hardiest of Eucalyptus and the grey tinged leaves on white twigs radiates an impression of silver, complimented by a grey /white smooth trunk. Pittosporum tenuifolium ‘Silver Queen’ is a large shrub which can grow to a height of four metres. Its latin name denotes thin leaves, these having white markings on the edges, giving an affect of a silvery foliage. It is an ideal plant for coastal areas. Popular small to mid-sized shrubs are lavender and Helichrysum, both release pleasant aromas, the latter being more known as the Curry plant due to its distinct curry fragrance. With regards to small shrubs and perennials, there are plenty available and more to choose from. Convolvulus cneorm is a small shrub native to the mediterranean and displays silk grey hairs on its evergreen foliage, hence it being more known as the Silver Bush. Santolina or Cotton lavender is ideal for ground cover and filling in gaps within the borders, the yellow pompom flowers provide a nice contrast with the silver fragrant foliage. Another popular ground cover is the perennial Lambs Ear or . It is also known as Silver Carpet and has oval, woolly silver leaves with fine hairs and is suitable for the front of borders, covering areas with its carpet, mat forming characteristics. There are numerous other silver foliage plants, the following are popular; - Senecio cineraria/Silver Dust - Sea Holly/ Eryngiums. - Cardoon/Cynara cardunculus - Bluebeard/Caryopteris - Honeywort/Cerinthe major - Rose Campion/Lychnis coronaria - Brunnera macrophylla/Jack Frost If not already in possession of silver leaf plants, then why not incorporate some into the garden, either in shade or full sun areas and if every cloud has a silver lining, then surely every garden should have some silver foliage.  Most, if not all gardens there will exist an area subjected to shade, an area of comparative darkness and coolness caused by a shelter from the direct sunlight.
As the summer approaches and the strength of the sun’s rays increase, the shady areas which are often neglected should perhaps be embraced and appreciated more. Shade is created by buildings, walls, fences or tree top canopies and when a solid structure is the cause, more often than not, it will provide protection against wind too. This microclimate can provide a pleasant seating area on a hard or soft landscaped surface, providing protection from the midday sun and strong winds. Climbing plants which are suitable to grow in shade are:
Certain types of climbing roses are also shade tolerant and some climbers are more vigorous than others which should be taken into consideration. Shrubs can be planted directly into the ground or the use of pots maybe more appropriate. As with climbers, many shrubs can provide a profusion of colour within an area of comparative darkness. Popular shrubs for growing in the shade are:
There are numerous other shrubs which are compatible with shade and it is advisable to research online or a visit to a nearby garden centre. The average temperature will also has a huge affect on the plants growing rate and an area of shade is most likely to have a North or North Easterly aspect and subject to cold, if not freezing temperatures during the winter. This should be taken into consideration before plant selection. Treetop canopies can provide full shade to a dapple shade and the choice of planting here should be more akin to a natural woodland environment. These would be perennials which return each year such as:
The above, once again can bring great colour and vibrancy to an otherwise sombre section of the garden. Therefore, no longer be kept in the dark, surround oneself with an abundance of colour and sally forth into the shade.  We often strive for an orderly and well maintained garden, one which looks tidy with regular pruning, mowing of lawns and the weeding of garden beds. Aesthetically pleasing and satisfying this may be, the garden, however, becomes devoid of any mess and untidiness, and this in due course can have an adverse affect on the wildlife and beneficial insects. The beneficial insects being those which create a natural ecological balance within the garden, attracting a range of prey and predators. These insects and mammals work in harmony and will reduce the unwanted pests which can attack the vegetable garden and shrubs alike. They will also lessen the need for any chemical applications. To entice these insects into the garden, a suitable, natural habitat is required, and the most appropriate is a dead wood habitat, essentially, a pile of logs or a wood stack. Winter is an ideal time to procure the dead wood, either from gathering any fallen branches within the garden or by pruning the dead limbs and branches, particularly from deciduous trees and shrubs. Avoid collecting the wood from natural woodlands and hedgerows as this will be disrupting an existing habitat and the natural environment. Alternatively, ask neighbours if they have any excess dead wood they are wanting rid of, I am sure it would be greatly appreciated. The location of the wood pile within the garden is critical for a successful dead wood habitat, it should be away from direct sunlight and sited in a full shade area, or with dapple light. This environment will augment the wood decay and encourage fungi, mosses, lichens and insects. To construct a log pile it is advisable to find logs with the bark still attached, the bottom layer of say four to five logs to be partially buried into the ground, the decaying wood beneath the soil’s surface attracts certain types of beetle. Ensure there are nooks and crannies for insects and mammals to enter and then add leaf litter into the gaps to encourage hedgehogs seeking hibernation. Another couple of log rows can be placed on top, the dark and damp conditions will lure centipedes, millipedes and woodlice which in turn attract the predators such as birds, toads and hedgehogs. A wood stack is constructed with smaller branches and twigs and is just as beneficial as a log pile for wildlife. Firstly, it is recommended that branches/stakes are driven vertically into the ground, forming a rectangular shape and with approximately half metre remaining above ground. Then start with laying the larger branches at the bottom and begin to fill the formed rectangular shape with the remaining branches and twigs until the desired height is reached. A mixture of wood is good for both log pile and wood stack, however, poplar and willow cuttings can have a tendency to re-sprout if in prolonged contact with the ground. The wood will slowly decay over a duration of time and more can always be added, thus, a permanent home has now been created to encourage the beneficial insects and assist towards a balanced ecological garden. If unsure how to dispose of the logs and wood cuttings, then why not transmute them into a dead wood habitat, as dead wood breeds life.  December is an ideal time to plan a garden reset or makeover in preparation for the following spring and if not practising already why not try cold frame gardening. Cold frame gardening is a method of planting different types of green life, mainly produce, in a microclimate created by a man-made structure. The addition of a cold frame within the garden enables the growing season to be extended. They are versatile, require little surface area, ideal for a small garden and are easy to build, alternatively, they can be purchased flat pack or ready-made from an established retailer. Essentially a cold frame is a bottomless box with a skylight, a halfway house between a greenhouse and exterior planting. They can be positioned directly onto any garden bed and assist in warming bare soil in early spring. The transparent lid allows the sunlight to enter and simultaneously prevents heat loss by convection which would otherwise normally occur, particularly during the night. Thus, a microclimate is generated with an increase in soil and air temperature and also providing protection against the elements, such as strong wind, rain, hail and even snow. Plants can be started earlier in spring, such as seedlings which can then be transplanted to open ground once established. A variety of produce can be grown in a cold frame, the most popular being lettuce, spinach, kale and green onions. However, a variety of root vegetables and brassica can be grown too. When deciding to position the cold frame, take in consideration that full sun is essential and the transparent cover should slope downwards at a slight angle facing southwards to absorb the heat from the sun and to allow for rain run off. A cold frame can be constructed from any material, the sides being of a solid material such as wood or masonry and the top being of a transparent material such as glass. A wooden structure can look aesthetically pleasing as well as being portable too, whereas, brick or block structure will be a more permanent feature and choice of location should be greatly considered before building. The most simple method of construction being straw bales used as sides and an old disused glass window or door placed on top. Imagination is key! It can be designed and built to suit your particular needs, hinges and handles attached for ease of opening the cover and if preferred one crop could occupy the entire cold frame or a combination of crops in rotation to provide produce throughout the year. It is important to ensure the transparent cover is clear from any debris, as this will inhibit heat absorption and with crops being under cover, regular watering will be required. Increased humidity can be a problem within a small enclosed area, therefore, allow for slight ventilation within the cold frame structure. Specific frame designs are available so they can be positioned on a hard landscaped surface such as paving. These can take on the appearance of a miniature greenhouse and more suitable for potted plants. Cold frames are cheap to buy, easy to build and easy to maintain. They can be sited directly onto a garden bed, gravel or a paved surface and are a valuable addition to any garden, large or small. A mobile and modular solution for growing plants, lower in price and occupying less space in comparison to a greenhouse, there are many advantages of cold frame gardening. contribution from Oliver David Cook  They maybe all around us now and covering large areas of the garden, often regarded as a hindrance when it comes to the maintenance of a neat and tidy garden. But, alas, leaves falling to the ground is a message from nature which one should take heed of, and that message being leaf matter is the best natural and free mulch available for the gardener and grower.
Fallen leaves can be found residing in many areas, from resting on the lawn to wind blown corners of the garden and now is the time to sally forth and gather. A large pile of leaves can be transmuted into leaf mould, the decomposed matter formed when the leaves have decayed over time. The leaves can be stored in plastic bin liner bags with a few holes pierced in the sides and bottom, once full, a sprinkling of water is advisable then storage in a shady area of the garden is essential and the following autumn the rotten leaves form a crumbly rich surface mulch. To be left for a second or third year will allow for increased decomposition of the leaf matter and this, with its added microbes, can then be used as a conditioner and soil enhancer which can be dug into the soil to aid in water retention for drier ground and for improving drainage in heavier soils. If preferred a leaf storage bin can be constructed and there are numerous methods of construction, one composed of chicken wire which permits air to travel through, being the most simple. Once a large amount of leaves have been placed into the bin, apply a sprinkling of water and then cover with some black plastic sheeting on top to encourage the decomposition. Leaf mulch is high in nutrients which will pass slowly into the ground below. As with all mulches it prevents the ground from drying out during the summer months and from becoming too cold or even freezing in the winter months. It also reduces the opportunity for the unwanted plants referred to as weeds to grow. The leaves can be gathered regularly as they fall with hand tools such as a rake or broom, a lawn mower can be used on a higher setting to collect leaves from the lawn whilst shredding at the same time. If the leaves are not collected soon after falling, then they will dry out and loose their nutrients. If your own garden is devoid of fallen leaves then maybe ask the neighbours, I am sure they would be happy with the assistance of leaf clearing. Or vice-versa, others in the neighbourhood may require leaf mulch too. The coming together can create a community free leaf mulch, this way the local gardens will never be without a mulch or compost. It is advisable to avoid leaves which have been lying on roadsides, they may contain toxins. Certain leaves will break down faster than others, Horse Chestnut leaves taking longer than Oak leaves. The leaves from Walnut and Eucalyptus do contain a natural herbicide, this may inhibit the growth of plants within the area the mulch or mould is applied. The splendour of the autumnal colours from bright yellow to orange to a crimson red, it is one of natures finest displays, the deciduous trees then sleeping for the winter months. They took nutrients from the ground to assist their growth during spring and summer, and now is the time to give back to nature and this can be achieved by gathering the fallen leaves and making a leaf mulch or mould full of natural nutrients. Contribution by Oliver David Cook  Early autumn is an ideal month to divide the herbaceous perennials of the garden. These are the flowering plants which die back each winter, the roots remaining dormant beneath the soil until the arrival of the following spring, this bringing warmer temperatures which triggers new growth to commence once again.
There are a variety available, producing a beautiful array of colours for the entire summer season. Popular herbaceous perennials are: - Geranium - Phlox - Salvia - Delphinium - Aster - Hostas The question is why to divide? Herbaceous perennials can outgrow their space and look rather messy, particularly in the centres and after division, older plants will have an opportunity to rejuvenate. The garden beds overall may have become overcrowded with plants encroaching on others adjacent to them and without dividing, the following summer the crowding will augment. It is a productive method to increase the number of plants within the garden and to fill any empty spaces that may exist, this being division is quicker in comparison to growing from seed. It can also save money, if the garden has recently been landscaped then it is an excellent way of adding plants and colour to a newly formed bed. When dividing, it is advisable to cut down the summer growth of the taller plants near to the base, then with a garden fork gently lift the plant working outwards from the centre as the most vigorous growth is found on the outer areas of the clump. Alternatively, the traditional method of digging deeper around the perimeter of the plant with the intention of lifting the entire perennial. A spade can be used on the tougher plants such as Hostas and slicing the clump in two after being lifted. The smaller plants such as Geraniums, clumps from the outer edges can be lifted using a garden spade, then once lifted, they can be divided again into smaller clumps with the use of a sharp knife. Perennials with tubers or rhizomes may naturally fall apart when dug, otherwise the tubers are often visible above ground, indicating where to divide. The divisions should be planted as soon as possible and well watered, part of the clump could be replanted in the same position or a different area of the garden. It is beneficial to clean the soil from the roots, the advantage being the health of the roots can be seen as one does not wish to replant damaged or diseased roots or tubers. When ever a plant is lifted it is subjected to shock, however, during the dormant time of autumn the shock is less profound. The plants growth cycle after division will be slow as it recovers from this disturbance. The age old saying being; ‘After you divide a perennial, the first year it sleeps, the second it creeps, and the third year it leaps’. Contribution courtesy of Oliver David Cook on behalf of Green Landscapes Cornwall Ltd  Lavender is without doubt one of the most popular shrubs to be found in any garden and with good reason too, providing a plethora of pleasures from the amazing aroma to the wonderful lilac flowers, particularly as they sway hither and thither in a gentle summer breeze. Planted alongside paths and walkways, as a small hedge, the perfume emitted is
therapeutic for the person, whilst at the same time attracting butterflies and bees. Planting lavender in clumps or in hedge form ensues a profusion of blossom and is more beneficial for the insects as it means they can jump from flower to flower with ease, compared to a sporadic planting plan. Towards the end of August is the favourable time to prune and harvest the flowers, the soil temperature is at its warmest and once pruned the plant will have an opportunity to grow new shoots before the approaching winter, these shoots will then spring into life the following year. Lavender angustifolia is by far the most suitable to grow here in the UK, the varieties Hidcote and Munstead being the most popular, the latter producing a slightly darker flower. Both fall into the RHS pruning group 10 classification, meaning they flower on new wood and regular pruning will prevent them from becoming too woody. The best time of day to harvest lavender for its aromatic properties is early morning, during this time the oils of the flowers are most profound. As the daytime temperature increases the fragrant oils dissipate and the flowers will then begin to open up more and this is the desired time to harvest for decorative purposes. It is important to use sharp secateurs or shears for pruning as a clean cut is essential and one must avoid from cutting too low into the wood stem section as this will prohibit any new growth which is formed on the upper section only. Aim for cutting one third of the leaf section and in doing so forming a nice evenly rounded mound for aesthetic purposes too. The cut stems and flowers can be bundled together with an elastic band or garden twine and hung for drying away from direct sunlight and in a dry sheltered location. Once the lavender has dried, approximately 3 weeks, the buds can be rubbed or shaken off and stored in a lidded jar. There are numerous applications for dried lavender with imagination being key. The reputed therapeutic benefits include induced calmness, promoting sleep and lowering the heart rate all attributing to a more relaxed state. To enhance the aromas of the house, dried lavender can be used to aid cleaning with a sprinkling of the flowers on carpet prior to vacuuming to release the fragrance. Lavender oils also have multitudinous benefits and uses and a visit to the UK’s most southerly lavender farm based here in Cornwall is highly recommended. Here a wide range of products can be purchased, providing much inspiration too. https://www.cornwall-lavender.co.uk/ Contribution by Oliver David Cook on behalf of Green Landscapes Cornwall Ltd  Garden Inspiration During Lockdown..
We have recently experienced what was known as a lockdown and there has been much uncertainty. But what was certain was the extra time which had become available and enabling more time to devote to one’s own garden and to encourage inspiration for a garden makeover or similar. It maybe starting to notice particular areas of the garden, at certain times of the day, are more desirable to sit and relax in, areas which went previously unnoticed before, prior to the lockdown. A corner of the lawn, for example, subjected to immense spring sunshine, could be transformed into a landscaped seating area for all to enjoy. There has been more time to ponder how a section of the garden could be better utilised and the potential of a transformation. It may be an area is suitable for growing produce, ranging from small fruits and berries, a selection of vegetables or even the planting of fruit trees, which could be trained in an espalier fashion against a south facing wall. Or, a sensory garden to enhance the time of relaxation... For sound, the installation of a water feature and the sound of running water is extremely therapeutic and would also entice wildlife into the garden. For scent, a variety of different plants are available and with a specifically designed planting plan, pleasant aromas can be enjoyed throughout the year. For sight, from decorative hard landscaping creating vistas to formal and informal designs it is limitless to what can be achieved. The choice and range of plants from architectural to wild flowers will have a dramatic affect on the appearance of the garden. All of the above will entice wildlife, particularly birdlife, which are enjoyable to watch and the diverse range of bird song being soothing to listen to. Inspiration may come from perpetually looking at a rather bland boundary fence or wall which would benefit from climbing plants attractively trained across them. These could be planted in a raised planting bed constructed in front of the existing boundary either from brickwork, coloured walling or timber sleepers to improve the entire aesthetics of the existing fence or walling. Does the garden slope considerably and could it be levelled or even terraced into two or more separate levels, each level having a different theme, from a lawn section to a hand landscaped section to a wild-flower area, imagination is the key. Or is the desire to have the immediate area at the rear of the house transformed as an exterior room, an extension of the house for alfresco dining, to enjoy those warm summer evenings when the weather is most genial. An area of dapple shade is a great attribute to the garden. The construction of a timber pergola is the preferred option with a climbing plant or two growing over the cross beams at the top to provide partial protection against the sun’s rays. Whatever the change made to the garden, the extra time at home has provided much inspiration for all. For more inspiration visit The National Trust website who have uploaded virtual tours of their properties. https://www.nationaltrust.org.uk/lists/virtual-tours-of-our-places  During the peak months of summer and particularly July, the garden more often than not is in
need of water and it is important to monitor all perennials, shrubs and lawn to ensure they are receiving a sufficient amount. Hanging baskets, container plants and newly planted summer bedding plants are the most prone to drought due to being shallow rooted. Shrubs and trees will be deeper rooted and will be able to source their water supply from further down beneath ground level, that is providing the water table level has not dropped too low from a prolonged period of dry weather. There are two sources of water supply available for use in the garden and they are tap-water and rainwater, the latter being natural and more beneficial as it contains no chlorides and has zero hardness. However, when there is a limited supply of rainwater, then tap-water will be the only option. Ponds and water-features this time of year can drop to a low level and will require the use of a hose for a regular top up to maintain a sufficient level, this will also benefit any fish, particularly with the addition of a spray attachment which will aid in aeration. To maintain a lush green lawn during dry periods can be challenging and it is advisable to water only once a week to minimise wastage. An excellent suggestion by the RHS is to place an empty jam-jar on the lawn and with the sprinkler running for a sufficient time, that is until 13mm (0.5inch) has collected at the bottom of the jar. This is the optimum amount before excess water is wasted as the lawn has now received its required amount. With regards to watering plants, it is more economical and efficient to use a watering can compared to indiscriminate watering by a hose. Water management is extremely important during periods of drought and the essence of this is the method of water storage and harvesting. The most popular method by far is the use of water butts positioned below downpipes which then take the run-off of rain water from various roofs such as garden sheds, greenhouses or even the house. With the water butt raised up on blocks, the tap at the base can be utilised to fill watering cans with the valuable stored rain water. The question then is when is the best time to water the plants and lawn of the garden? The blades of grass will hold moisture in the early hours of the morning, the moisture retreating to the roots around midday. It is a general consensus that to avoid evaporation the best time to apply water is in the morning or evening whilst avoiding the heat of the midday sun. The morning application is the most favoured, this is because the ground will be drier as the day progresses compared to the evening time, equating to a reduced chance of mildew diseases and the arrival of slugs and snails. The final question being: Is it best to water from the top, watering the leaves too, or from the bottom and the roots only? The jury is still out! |
