The first half of April:
· Feed shrubs and roses - read label directions for special instructions.
· Take a soil sample to determine exact amount of nutrients the soil needs to grow and produce flowers or fruit.
· Mow lawn if grass is over 2-1/2 inches tall. The ideal mowing height is two inches. Closer cutting weakens the lawn and opens it to invasion by crabgrass and other weeds.
· Allowing the lawn to grow too tall gives it a ragged appearance, may create problems with accumulated clippings, and will cause matting if played or trampled on.
· Prune and shape spring flowering shrubs after blossoms fade.
· Prune roses before April 22.
· Prepare garden soil for spring planting.
Begin regular scouting program for fruit trees. Pesticides should be used only when pest populations are high enough to cause damage to plants and damage reaches the economic injury level.
