The water absorbs the heat during the day and acts like an insulator as temperatures drop overnight. The cloches have pockets that you fill with water. Rick really loves the Wall O Water cloches which allow him to plant tomatoes four to six weeks before he would otherwise be able to. Rick’s favorite cloches are called “Wall O Water.” You can use simple items such as a milk carton turned upside down, a clear plastic bin turned upside down, or you can purchase specific cloches. ClochesĬloches are great for protecting individual plants. The mulch actually inhibits the soil from warming up and delays germination and root development.Īs long as you’re aware of this and take proactive measures, mulch can be used. Though it will help retain heat in the soil in the fall (for a short period of time), it won’t help the soil heat up earlier in the spring. Though mulch does a good job insulating your crops, it won’t necessarily extend the growing season. By adding them in the spring and fall, you’ve essentially added three months of growing season to your year. You can utilize this method on the other end of the growing season by using row covers into the fall. As soon as the snow melts in March, he’ll plant his hardy vegetables like carrots, spinach, kale and chard, then cover the garden with a row cover and just let them go.ĭoing this extends his growing season and allows him to plant about six weeks sooner than normal. In fact, they’re what Rick uses in his own garden. They’re inexpensive and can help protect plants from light frost. So I asked Rick what his opinions were on extending the growing season without additional structures.
I know many of us have a lot going on, and building structures, even cold frames, is not in the budget. It is possible to extend the growing season without having additional structures.

So if you’re in zone 5 and you have a cold frame with a row cover inside, you’re essentially now in zone 7 for your plants. He says with each layer you add to your crops, you’re increasing your growing zone by one. Rick also utilizes row covers inside his hoop houses and cold frames for an added layer of protection. This isn’t possible for many of us, but it’s worth mentioning because row covers can be a much less expensive option. If you live in a climate that doesn’t get too cold in the winter (doesn’t dip more than a few degrees below freezing), you may get away with simply putting some heavy fabric row covers over your garden to protect from light frosts. Some people will even build a box using straw bales with an old storm window on top to capture the light. He says the wood helps insulate, while the plexiglass lets plenty of light through. Rick prefers wooden boxes made with plexiglass.
