Rowan Berry Care: August Irrigation Crucial for Vitamin Rich Fruit

Rowan berries are a concentrated source of vitamins C, P, A, and B group, but maintaining the tree in August is critical to ensure these fruits develop without being lost to pests or winter vulnerability. August Care: Irrigation and Nutrient Management During August, rowan trees actively fill their berries. Moisture deficits during heatwaves are unacceptable; adult trees require 3–4 buckets (approx. 25–33 liters) of water per tree if the soil is dry. To avoid root damage in high temperatures, irrigation should be performed to ensure gradual soil penetration. Fertilization strategies must shift in late summer. Nitrogen-based additives are prohibited as they stimulate the growth of young foliage that will not harden before the first frosts. Instead, phosphorus-potassium compositions—such as superphosphate or potassium sulfate—should be used to strengthen the wood and improve fruit flavor.
