Ground warming Using Polythene / Plastic – Methods and Preparation for Your Vegetable Plot, Allotment & Garden

Allotment PreparationWinters in the UK can be bitterly cold and do a lot of damage to your allotment or garden. There are ways to protect your plants through the cold months that include frost fleece, greenhouses and mulching. However today we will be concentrating on the preparation of soil for planting a new crop of vegetables or plants. As the winter turns into spring you will want to plant as early as possible to make the most of your garden; one way to speed this up is to make sure the ground is at its best quality to receive seeds.

You will want to commence the warming process in the late weeks of winter/early weeks of spring. The idea is to heat the ground, which coincidentally is very good at retaining warmth, so you are able to get your crop off to an early start. Polythene sheeting is the most effective product for the job; gardeners often use clear or black. Clear poly placed over soil allows the sun’s rays to pass through and trap the heat that they cause, not dissimilar to a greenhouse. Black can be used because it absorbs the most light and therefore becomes hot. Both types of plastic are suitable and have been proven to be effective.

Polythene for ground warmingYou will need to cover the entire area of soil in polythene, making sure any heat cannot escape. When purchasing I recommend plastic that is at least .25mm thick (250mu/1000g) as it will hold in more heat and is strong enough to give a good resistance against ripping. Pegging the plastic down with groundsheet pegs or any other steel pegs and burying the edges, covering them in earth, will certainly do the trick; however gardeners do often use bricks or large stones as an economical alternative. Leave for a few weeks and it will help prevent the ground from freezing and increase the temperature ready for the spring.

Once you believe the ground is ready to plant in then you can remove the poly and hoe the earth. I recommend removing any signs of weeds or growth to give your crop the best chance. You can of course apply weed control or mulch at this stage before planting to reduce the amount of future maintenance. Do not use polythene as weed suppressant, I does not allow drainage and causes water to pool in your garden causing all sorts of trouble. Many gardeners are different and many ground treatments are used to nourish the soil; depending on your crop you may wish to look at options.
