Boysenberries are somewhat tart and juicy with vines, and started in California. They style just like a cross between a blackberry and a raspberry, and are closely connected to blackberries. Similar to caneberries, boysenberries require fertilizer only through the springtime. Since boysenberries don’t require huge quantities of fertilizer, fertilizer is not actually needed by them unless their progress is bad. They accomplish the most steady progress with annual spring-time fertilization.
Mix some compost to the soil at least a month. The compost you include, the more nutrients the soil will have. 6 to 8″, mixing it in using a garden fork or tiller. Coastal soils may be sandy, and compost helps them have more nutrients and maintain water. Inland soils tend to be made up of clay that is large, and compost increases the drainage of clay soils that are heavy.
Fertilize the berries in late winter or the spring when they begin developing for the period. Either spread fertilizer throughout the bottom of the bushes that were boysenberry or use fertilizer in a line about 1 foot from the plants. When when working with a well-balanced 202020 ratio fertilizer, use 2 to 3 lbs per 100-feet of boysenberry rows that are. Coastal sandy soils tend to require a well-balanced-ratio fertilizer, while in land soils can usually use a fertilizer using a greater ratio of nitrogen. Ammonium nitrate is excellent high-nitrogen fertilizer. For a natural garden, substitute cottonseed meal, alfalfa meal, blood meal, fish meal or a different fertilizer.
When they start to bloom in the spring fertilize the berries. Apply 2 to 3 lbs per 100-foot row.
