![]() 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’.

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! Summer bedding plants provide and create a temporary floral and foliage display during the
warm summer months. The form of display can be within the garden beds, hanging baskets or a container of your choice. It is an excellent opportunity for one to become creative, not only with the variety of plants available but, with also the type of container which can be used. For example, a disused wheelbarrow or a pair of old boots can make authentic and attractive planters. Although grown from seed, they can be purchased in cellular trays and multi-packs ready for planting and providing an almost instant effect. The majority of the summer bedding plants are categorised as tender/half-hardy perennials, hardy annuals, half-hardy annuals and hardy biennials. The following are some of the popular choices: - Begonia - Sweet Peas - Geranium/Pelargoniums - Petunia - Lobelia - Busy Lizzies - Heliotrope - Nemesia - Cosmos - Alyssum - Calendular/Marigolds. - Dianthus. Generally, summer bedding plants are regarded as being frost tender and suitable for the summer months only. They are excellent for filling any bare or vacant areas within the garden beds, the larger areas can be planted with what is known as carpet bedding plants. Essentially, these plants are more compact and closely integrated which give the effect of a carpet and it is possible to create various different designs and patterns by using different colours of blossom. This is widely seen in public gardens and commercial landscapes around the country where many thousands of plants are used, the design layout being from a computerised plan. The private garden does not have to be quite as formal, but an effective display can still be achieved, whether the same colour is used in large clumps or long singular rows, it is another opportunity to be creative in the garden. Hanging baskets are a great addition for any garden or property and bedding plants with a pendulous and trailing characteristic will create the best effect. Popular plants suitable for hanging baskets are Lobelia, Begonia and Periwinkle, but, why not try the edibles of strawberries and tomatoes. Colour themes have long been popular and simple to achieve, this is known as monochromatic, where each container or hanging basket is composed of plants with foliage or blossom in shades of the same one colour. Again, another opportunity to be creative. Regardless of the choice flowers and the location of planting, either within the borders or container, the addition of summer bedding attributes to the garden a feeling of completion. There will be minimal bare areas, a surrounding of flora with a profusion of colour and one must not forget, a chance to be creative. Contribution by Oliver David Cook THE CHELSEA CHOP
When one talks of gardening in the month of May, without doubt the Chelsea flower show will spring to mind. However, due to the unprecedented events this year and the prohibition of the coming together of large groups of people and social gatherings has equated to the nations favourite flower show unfortunately being cancelled. For the first ever time the show will be a virtual event which can be viewed online: Nevertheless, just because there is no actual Chelsea flower show it does not mean that we cannot partake in the Chelsea Chop. The Chelsea Chop, to clarify, is a pruning method to determine the size, shape and the flowering season of many of the herbaceous perennial plants. It is so called as it is carried out towards the end of May, coinciding with the RHS Chelsea Flower Show. It is suitable for late flowering perennials. But, why should we carry out the Chelsea Chop? It goes against the natural instinct to drastically cut back a plant prior to flowering. If a herbaceous perennial is chopped down to half its height, using secateurs or shears, it will delay the flowering until later in the summer. The plant will be more compact and shorter which equates to less staking and the flowers can be more numerous if slightly smaller. This is because the top shoots have been eliminated and side shoots lower down will develop and produce the new flowers. Overall, the plants will look much tidier and less leggy. If only half of the perennial clump is cut down, such as the front section, this will induce a prolonged flowering season as the rear section will flower first, then followed later by the pruned front section. Plants which can benefit from the Chelsea Chop are: - Phlox paniculata - Echinacea purpurea - Helenium - Rudbeckias - Penstemons - Nepeta The following are suitable for coastal gardens: - Anthemis tinctoria - Sedum ‘Herbstfreude’ - Achillea - Aster ‘michaelmas daisy’ - Campanulas The Chelsea Chop is hugely beneficial for perennials subjected to the coastal environment of wind and salt spray. The chop creating shorter and stiffer stems and more stability. The Chelsea Flower Show will be greatly missed this year, so why not visit the gardeners world website and their own guide to carrying out the Chelsea Chop. https://www.gardenersworld.com/plants/how-to-do-the-chelsea-chop/ |
