The pumpkin is characteristic of autumn and synonymous with October and Halloween, it is also variety of squash and its true name being a cucurbita, which is the latin name for gourd. A gourd being a trailing or climbing plant, containing large fleshy fruits with a hard skin, some varieties being edible, others for decoration.
As a guide, the middle of October is an ideal time for harvesting of squash and pumpkin, however, one should be vigilant, they are frost tender and to harvest before the first frost is strongly advisable.
Allow the fruit to mature and colour wholly on the plant prior to the harvest, the colour being dependant on the type and variety which is grown.
The skins should be hard and not easily dented by a fingernail and its shine will also be slightly diminished. A soft outer skin will be susceptible to damage and eventual rot.
If the fruit cannot be harvested before a frost or a large amount of rainfall, then it is recommended to raise the fruit off from the ground, thus it is not in contact with the soil to lessen the chance of rot and infection. This can be done by the use of straw, cardboard or a solid object such as wood or a brick.
To reduce the chances of disease and infections it is best to harvest on a dry day and using a sharp knife or pruners and cut the stalk as far from the fruit as possible, ideally 10cm. The stem remaining intact with the fruit is essential for good health and storage and for this reason do not be tempted to carry them by their stems, the weight of the fruit causing it to brake off.
The fruit can then be cured, which entails leaving them exposed to higher a temperature, either outside or inside on a windowsill for approximately ten days.
This curing will improve flavour, heal any wounds and harden the skin. After they have been cured they can store for two to three months in a cool, dry and dark environment, ideally about 10c. However, beware that it does not become too
cold as they may soften and begin to rot.
During storage, ensure they are not touching each other and preferably, they are on a wooden surface or cardboard, do not store on concrete as it will increase the chances of rot.
Certain varieties of squash and pumpkins are suitable for a longer winter storage, whereas, others are best to be consumed this autumn, therefore, it is best to check which type you are harvesting. The popular squash varieties being the butternut, the golden butternut (coquina) and the striped harlequin are enjoyed with great gusto soon after harvesting.
Pumpkins which are best for consumption are not usually the best for Halloween carving and Jack-O-Lanterns. A rule of thumb being a smaller denser pumpkin will contain more flesh and are best for cooking, whereas, a larger pumpkin will have more area for artwork and with less flesh it will be easier to carve.
Gourds are extremely high in nutrients and being classified as a fruit they contain seeds too, which can also be salvaged and consumed.
It maybe for the culinary delights or for decorative purposes, either way, enjoy the wonderful squash and pumpkin which nature has provided us and after Halloween, why not return the pumpkin to the natural environment and use it as a bird feeder? It will be greatly appreciated.

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:
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’.

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
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.

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
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
The following are suitable for coastal gardens:
- Anthemis tinctoria
- Sedum ‘Herbstfreude’
- Aster ‘michaelmas daisy’
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.
