When and how to fertilize? SUBSTRAL long-term fertilizer cones fertilize your plants for 6 months. The ideal application period is in spring. Do not use during the winter months. One application per calendar year is sufficient. 1. To determine the number of fertilizer cones, measure the pot diameter. Distribute the cones evenly between the plant and the pot rim. 2. Press the cones approximately 5 cm into the soil. If necessary, drill holes in the soil with a pointed object. 3. Then water the plant thoroughly. Application time: April to August. The working principle of Osmocote long-term fertilizer: The fertilizer beads are surrounded by an organic resin shell that controls the release of nutrients. Each fertilizer bead contains the nutrients in the same ratio. Water penetrates the resin shell into the fertilizer beads, dissolving the nutrients and making them available to the plants. Controlled by temperature and soil moisture, the nutrients are released through the shell and made available to the plants. After the nutrients are consumed, the empty resin shells are slowly degraded by microorganisms (after several months). Active ingredients: NPK fertilizer, NPK(MgO) 20-7-12(-2), mixed fertilizer with trace nutrients. For use in horticulture. Low in chlorine. Package size: 10 pieces.
