Growing Vegetable Garden On Plastic Sheeting
Seems fine safety wise but structurally may not be the best choice for the garden if you need it to support weight or water.
Growing vegetable garden on plastic sheeting. Consequently the best time for covering a vegetable bed in black plastic mulch is in early spring before the growing season starts. Plastic sheeting has many uses in the home garden. The most obvious advantage to using any kind of plastic sheeting is that it will prevent the growth of weeds. Black plastic prevents weed growth eliminating the need for hand weeding between your plants.
It also helps warm the soil for early planting. All in all it s a decent plastic to use for the garden but my only concern is that it is a more porous material and less sturdy making it not a good structural choice for the garden. But clear plastic will still let the sunshine reach your soil. Plastic sheeting for weed control offers the advantage of being impermeable.
It s generally more difficult for weed roots to penetrate plastic than fabric. Black sheeting commonly used in landscaping and commercial vegetable production deprives weeds of light as well as moisture. Lay heavy duty black polythene plastic sheeting on the ground and weight it down leave for 2 3 months in summer or six months in winter lift the plastic remove slugs and dig up perennial weeds dig over the soil and prepare it for planting. Using plastic row covers to extend your vegetable garden into the winter months can allow you to harvest fresh vegetables nearly year round.
Crops that grow in the cool seasons such as root vegetables peas spinach and lettuce does much better without the use of plastic sheet cover. Dig a 3 inch deep trench around the edges of your garden bed. The effectiveness goes down in cooler locations the effectiveness of garden plastic sheets or a black garden tarp goes down when used in the cooler coastal regions. Place the soil that is removed from the trench into a wheelbarrow for use later.
