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.

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
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
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.
