Harness heat from the sun for organic weed and pest control using the organic gardening method of solar soil sterilization. You can also hire dedicated pest control in Vaughan to know more about handling pest in your garden.
Solar soil sterilization offers the organic gardener an organic weed and pest control method that leaves the soil free from weeds, nematodes and harmful insects, yet ready to plant with new crops.
Soil sterilization harnesses solar power to heat soil temperatures above what weeds and pests can tolerate. Used in June, July and August, and September, soil sterilization creates a weed and pest-free garden bed without adding harmful chemicals to the soil.
Soil sterilization uses the sun’s rays to heat the soil to high temperatures. It’s totally natural, organic, and uses no fossil fuels. Best of all, it leaves behind no harmful chemical residue.
Many organic farms and growers use soil sterilization on a massive scale, but the home gardener can use it on a much smaller scale to the same good effect. Gardeners must pull mature weeds from the treatment area and remove rocks, stumps and branches. Then the soil is ready for sterilization.
In addition to weed pulling equipment such as gardening gloves, rakes, hoes and a wheelbarrow to carry away the weeds, gardeners wishing to try the organic weed control method of solar soil sterilization need a large roll of heavy duty clear plastic and a shovel. Only heavy, clear plastic works for soil sterilization. Dark plastic doesn’t allow the sun’s rays to penetrate the soil and silver-coated or reflective plastic simply bounces the rays back off the soil surface. The idea is to allow as much of the sun’s rays onto the soil through the plastic to bake it like an oven.
To use this method in the garden, follow these steps. Be sure to use this method during the hottest months of the year. In most gardening zones, June through September are the best months, but check with the local County Cooperative Extension office for local questions or general questions about soil sterilization.
There are a few cautions to keep in mind when using this organic gardening weed control method. The heat generated by solar sterilization kills most weeds but some may germinate. If so, pull them out manually. The high temperatures usually kill insect larvae and insects, but they also kill beneficial bacteria and fungi that colonize the soil. If you’re unsure of the whole process, best to reduce your risks by hiring professional pest control in South Florida (a place that has the most pests).
Apply compost, compost tea, or an organic fertilizer to the area after soil sterilization is complete to encourage colonies of helpful soil bacteria to form again. Do not use this method on or around existing plants; it will kill or damage them. Be sure to remove any tall weeds, since weeds, rocks and sticks on the ground may poke through the plastic and prevent proper soil sterilization.
