Oak wilt is a lethal fungal disease that causes oak trees to show leaf discoloration and overall wilt. Red oaks are more susceptible and are killed faster than the more resistant white oaks. This disease is spread most efficiently through root grafts, but also is spread by insect vectors.
Weed control in raspberries is necessary to reduce competition for water, nutrients, and sunlight. Cultivation and mulches are the most practical control measures for home gardeners. Cultivate the raspberry planting frequently during the spring and summer months. Small weed seedlings are destroyed easily. Large weeds are more difficult to control. To prevent injury to the raspberry plant roots, do not cultivate deeper than 2 to 3 inches.
