How can I protect my garden from the cold weather?
Cover the surface of the soil with a sheet of polythene, mulch fabric or roofing felt. The protective cover will keep out cold rain and late snow. Don’t worry about the colour of the material – dark colours will absorb heat from the sun and transfer it to the soil, but clear polythene will enable the sun to warm the soil directly.
How to keep soil warm in spring?

How do I keep my soil from freezing?
Water: It may seem counter intuitive, but water can provide protection from freezing temperatures. When dry soil freezes, moisture is pulled from the root, causing damage. If soil is moist, it can freeze without harming roots. Wet soil also holds more heat than dry soil.
How long does it take soil to warm up?
To really warm up the soil, you need some artificial methods. Cover the soil with plastic sheeting and leave it in place for about six weeks. This is approximately how much time is required to heat the soil enough for early plantings.
Does compost keep soil warm?
If bare soil works for your garden, you could distribute compost on the soil surface. Because it is dark in color, it absorbs the sun's rays even better than many soils that are various shades of tan.
Does straw keep soil warmer?
Straw is coarse and good at trapping air, making it an effective soil insulator in the both the winter and summer months. The insulation layer it provides between the air and the ground protects the soil from temperature fluctuations, and the plants or bulbs from extreme cold or heat.
How can I make my soil better in the winter?
Bark, wood chips, straw, grass clippings, rice and other seed hulls are great options. In addition to providing protection, they put nutrients back into the soil as they biodegrade, ultimately creating more organic materials for the microbes to feed on.
Will clear plastic warm soil?
Use wood ashes to melt the snow and then put down clear plastic to warm the soil. The clear plastic lets in the sunlight and UV rays and holds in the heat, allowing the soil to warm up.
Does black plastic warm soil?
Basic black plastic can warm soil temperatures from 5 to 7 degrees to a depth of 2 inches below the soil surface. Clear plastic heats up soil temperatures even more -- up to 14 degrees -- but its transparency does allow weeds to grow beneath it.
Is Wet soil warmer than dry soil?
Packed bare soils are warmer than loose soils, and wet soils are the warmest of all. Moist, packed soils can be as much as five degrees F warmer than unmowed cover crops during radiation frosts.
How do I increase the heat in my compost?

Where do you store potting soil in the winter?
Any storage containers that will keep the soil dry will work, including bins, small garbage cans, or heavy-duty plastic bags.

Why do we care about getting the soil warm early?
Why do we care about getting the soil warm early? Warming your soil in the spring allows you to get your cool-season crops started weeks earlier than you otherwise could . Most importantly the warm soil gets the seed germinating faster than they would otherwise!
Why is it important to warm soil in spring?
Most importantly the warm soil gets the seed germinating faster than they would otherwise!

Can you grow spinach in the cool season?
The same advantages apply to any cool-season crop. In fact, if the soil has dried out, you can use this method to get many of the really hardy crops like spinach and kale planted and germinated more than a month sooner than you could otherwise.
How to use compost in bare soil?
If bare soil works for your garden, you could distribute compost on the soil surface. Because it is dark in color, it absorbs the sun’s rays even better than many soils that are various shades of tan. Adding 2 or 3 inches on the soil surface gives the garden a double treat. The soil is warmer and at the end of the season, the compost is tilled into the soil to work its magic on plant roots in coming years.
How to get water under plastic plant?
Watering with a hose placed close to the base of the plant will get the water under the plastic or by laying a soaker hose under the plastic. Moisture can be directed to the root zone by only hooking up one end with the other closed off. If using plastic, buy the thickest plastic that you can find.
How does mulching work?
This is when a technique called “dust mulching” can work. The soil is lightly tilled or hoed to a depth of 2-3 inches. The loosened soil dries out and heats up. The compacted soil below the tilled area holds in moisture .
How to keep plastic from running away from home?
Another technique is to cover the bare soil with black or clear plastic. This will allow heat to penetrate and the plastic will hold it in more successfully than just bare soil. It is important to anchor the plastic so windy days do not cause your plastic to run away from home.

Can you use straw mulch on vegetables?
Another possibility would be not using organic mulch like straw on some or all of your warm-season vegetables. Mulch is invaluable for keeping soil temperatures down because of its insulating ability. Bare soil that has been loosened will absorb the sun’s rays. This is when a technique called “dust mulching” can work.
Organic versus Sustainable
That leads me to organic versus sustainable. Using plastic to warm up the soil is neither organic nor sustainable. Some folks might make a case for organic because the material isn’t left in the garden and only used mechanically, but they can’t pretend using an petroleum based product for getting a jump on the growing season is sustainable.
Clear Plastic
If you must use clear plastic to warm up your garden soil, then know it’s extremely effective at doing this. But do not leave it on the soil after you plant the tomatoes. It will produce too much heat and damage (or kill) the roots.
Black plastic
Black plastic is no more sustainable than clear plastic and while it does an adequate job of heating up the soil, it’s not as effective as clear. It can however be left on the soil all season long in northern areas. In more southerly gardens, the heat may be too high.
Organic Mulch
My preference is for an organic mulch. It is clearly organic and sustainable. And as it degrades, it feeds the garden rather than sterilizing the soil.
Frost Fabric
Frost fabric is relatively quick and easy to lay down. You could build a framework for the sheets but it’s just as easy to pin them to the ground.
High Tech
I did get asked once about laying pipes under the ground and hooking them up to a hot water solar heater. I suspect that would work nicely to give you heated soil (see note above re cold air) but it’s a lot of work and cost for very little gain. Now, if this were in a greenhouse it would be completely different.
How to ensure soil is warm enough for gardening?
The best way to ensure your soil is warm enough and ready in time for the gardening season? Choose an appropriate garden location that gets enough sun!

A quality thermometer will do the trick. Pick one designed especially for monitoring soil temps. The ground may still be cold down below even if the surface temperature is nice and toasty, so a thermometer will give you a better understanding.
Why is it important to test soil temperature?
Did you know that just because the ambient air temperature is nice and warm that the soil temperature may not match up? In the winter, for instance, the soil helps to insulate the roots of overwintering plants. That’s another reason it’s vital to test the soil.
What are the different soil temperature classifications?
Soil Temperature Classifications. One useful tidbit to keep in mind is that there are four different soil temperature classifications. Minimal, optimum, realistic, and maximum. Note that these temperatures are not the same for all seeds. Minimal temperature: This is the bare minimum required for germination.
Why mulch in summer?
Water retains heat and moistened soil may be cool er than the air, which is why mulching is helping for plants that prefer cooler temperatures. Mulch has helped me prevent my lettuce from bolting too quickly in the summer. Shade cloth is another superb tool for keeping the sun from harshly affecting your plants.
Why is it important to know the temperature of soil?
Knowing the precise soil temperature is useful for getting your seeds to germinate, whether indoors or outside. It’s also a helpful guide for how well your seedlings or transplants will do if planted outside . The right soil temperature makes all the difference. If the soil is too cold, some seeds won’t germinate.
