The Roberts family have had a large family garden for several years. Every autumn, after the first frost, they pull up the dead plants
and cover the garden rows with black plastic. When it is spring and planting time, they plant seeds though holes they have poked in
the plastic. Why do the Roberts use the plastic covering?
A)
The black plastic keeps the weeds from growing in the bare soil.
B)
The black plastic keeps the soil warm so the seeds will grow in the spring,
The black plastic helps the organisms that live in the soil survive the
winter
D)
The garden space will be covered with grass and animals will graze in the
area.

A black plastic mulch conserves soil moisture by preventing it from evaporating. Only the exposed soil in the holes where the vegetable plants are growing lose water to evaporation. This means that more moisture is available in the surrounding soil for plant roots, and you spend less time on watering the growing crops.
