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.

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.
