Substral® Osmocote® A slow-release fertilizer for berry bushes (strawberries, raspberries, blackberries, currants, gooseberries, etc.) and fruit trees (apple, pear, cherry, plum, etc.). Reliable and safe fertilization tailored to the plant’s needs, released gradually over 6 months through the combined action of heat and moisture. No risk of over-fertilization with nitrates. This complete fertilizer is rich in potassium, which promotes flowering, fruit ripening, and growth, and intensifies the flavor and aroma of the fruit. It also promotes timely woody growth of shoots. It increases the plants’ winter hardiness and resistance to diseases and pests.
Application: Once a year from April through August. The best time to fertilize is in the spring, at the start of the growing season. When applying top-dressing, spread the fertilizer evenly around the plant’s root zone and mix it into the soil. When fertilizing plants growing in mulch or on a lawn, make holes 10–15 cm deep at equal intervals through the mulch in the root zone. Distribute the required amount of fertilizer among the holes. When planting, mix the fertilizer into the planting soil.
Watering accelerates the onset of the fertilizer’s effect.
