Herbicides - Homeowners can use some chemical herbicides to control weeds. Please contact your local county extension agent for current recommendations. Use a similar pruning strategy the third year with the exception that several flower buds can be left on vigorous shoots. In the fourth year, the bush should be 4 to 5 ft tall and capable of handling a crop, but carefully thin flower buds to prevent overfruiting and severe permanent bending of young canes under the fruit weight. Prune during the dormant season.
Late winter is most desirable especially in the mountains.
With mature bushes that are excessively vigorous in spite of low rates of fertilization, cutting back the excessively vigorous shoots in late July will help control bush height and increase yield. Yield - With good care, mature highbush and rabbiteye plants should produce more than 10 lbs each year. Rabbiteye varieties can, on occasion, produce up to 25 lbs per plant. They can consume the complete crop from a small planting. Plastic or cloth netting draped over the bushes or supported on a framework, while the fruit is ripening, is the only practical control.
