Cultivate by hoeing to break up soil crusts and control weeds. Shallow rooted annuals are injured by deep, vigorous cultivation. Hoeing should be very shallow to cut weeds off just below the soil surface. As the annuals fill in, hand weeding may be the only practical alternative. Chemical weed preventers are available but they have a short life and must be reapplied. Most chemicals labeled for flowers do not give control of difficult perennial weeds.
Start by asking family and friends if they can recommend an agent. Compile a list of several agents and talk to each before choosing one. Look for an agent who listens well and understands your needs, and whose judgment you trust. The ideal agent knows the local area well and has resources and contacts to help you in your search. Overall, you want to choose an agent that makes you feel comfortable and can provide all the knowledge and services you need.
