There are several ways to control weeds. Mowing in the fall helps to reduce cover for rodents which can girdle or cut off trees. Mowing is not effective for controlling weeds and grass. Mulching is very effective for controlling weeds and reducing moisture loss, but it can be expensive and labor intensive. It allows moisture to penetrate and will last for five years.
Herbicides control weeds effectively when applied in proper amounts at the right time.
Like weed control, watering is critical during the early years of the planting. When watering is needed provide a good soaking once or twice a week. Light watering encourages root growth too near the surface making the plant susceptible to drought.
