Fertilizing methods of tiger thorn plum
As a representative of tropical succulent plants, the tiger thorn is deeply loved by horticulture enthusiasts for its unique spiny stems and gorgeous flowers. However, many people often encounter problems such as less flowering and long branches and leaves during the maintenance process. The root cause is often related to improper fertilization methods. Mastering scientific fertilization techniques can not only promote the healthy growth of plants, but also allow the tiger thorn plum to bloom with beautiful flowers all year round. The foundation is laid for the three key periods of scientific fertilization: basics of base fertilizer application Applying sufficient base fertilizer in the early stage of planting is the key first step for successful maintenance. It is recommended to mix decomposed sheep manure and bone meal in a ratio of 3:1, lay a 2-3 cm thick base fertilizer layer on the bottom of the basin, and cover it with a 1-2 cm plain soil isolation layer. This layered structure not only avoids root burning, but also continues to release nutrients for 6-8 months. Special attention should be paid to newly purchased plants that need to be delayed for 15 days before applying fertilizer to avoid damage to the roots. Dynamic adjustment of the growth period The principle of "thin fertilizer and frequent application" is adopted in spring and autumn: apply 1000-fold diluted phosphorus and potassium fertilizer every 20 days during the spring germination period, combined with trace element foliar fertilizer once a month; apply slow-release granular fertilizer after it cools down in autumn. When new leaves are found to be thinner and internodes are elongated, nitrogen fertilizer needs to be stopped immediately and potassium dihydrogen phosphate (800 times solution) should be added to adjust growth balance. Special stage maintenance strategy Implement the "two stops and one supplement" strategy during the summer high temperature period (>35℃): stop root application, stop nitrogen fertilizer, and spray flower specific amino acid fertilizer once a week. During the low temperature stage in winter, decomposed rapeseed cake fertilizer is buried shallowly on the surface of the basin soil, which can not only maintain heat but also slowly release nutrients. If winter flowering occurs, high-phosphorus water-soluble fertilizer (1500 times liquid) needs to be applied immediately.
Scientific fertilization needs to be combined with dynamic adjustment of plant conditions. It is recommended to conduct monthly soil EC testing to keep the substrate conductivity between 1.2-1.8mS/cm. When you find that the edge of the leaves is scorched or the new buds are shrinking, you should immediately stop fertilizing and rinse the soil with clear water. Remember the eight-character secret of "applying thin fertilizer frequently and adjusting it at the right time", and your tiger thorn plum will definitely bloom with amazing flowers.
