Answer to Question 1

A

Answer to Question 2

Mulch is created whenever the surface of the soil is modified artificially by covering it with straw,
leaves, grass clippings, paper, or polyethylene film. Mulching helps control weeds, regulates soil
temperatures, conserves soil moisture, and provides clean, weed-free vegetables. The mulching
material should be spread around the base of the plants and between the rows.
