How to make Clivia blossom
Clivia is popular among flower lovers for its elegant leaf shapes and gorgeous flowers, but many flower lovers often face the maintenance problem of "Clivia does not bloom." This article systematically analyzes the key factors affecting the flowering of Clivia, and helps you easily achieve the maintenance goal of blooming every year through four scientific maintenance strategies. 1. Lighting control strategies 1. Clivia is a semi-negative plant with full sunshine in spring, autumn and winter, but sufficient light is needed during flower bud differentiation. It is recommended to place the plants on an east or north facing window sill to ensure that they are exposed to soft light for 4-6 hours a day. Winter can be extended to 8 hours of light to accumulate nutrients needed for flowering through photosynthesis. 2. Scientific shading in summer requires a sunshade net with a shading rate of 60% from May to September to avoid strong light at noon from burning leaves. The "morning sun and evening cover" method can be used to receive direct light before 10 a.m., and maintain a bright scattered light environment during the rest of the time. 2. Temperature difference stimulation plan 1. The temperature difference between day and night controls the flower bud differentiation period in autumn. It is necessary to maintain a temperature difference between day and night of 8-10℃. Keep it at 20-25℃ during the day and cool down to 12-15℃ at night. Natural cooling methods such as opening windows at night and placing balconies can be adopted, and the effect of promoting flowers is significant for 30-45 days. 2. Seasonal temperature difference management Winter requires 2-3 weeks of low-temperature vernalization of 5-10 ° C, and can be moved to an enclosed balcony or garage. Pay attention to avoid frost and cooperate with water control measures to activate the flowering mechanism of plants. 3. Nutrition supply system 1. The basic fertilizer is selected to apply balanced nitrogen, phosphorus and potassium fertilizers (15-15-15) every half month during the growth period, and apply high-phosphorus and potassium fertilizers (10-30-20) during the budding period. It is recommended to use organic fertilizers such as decomposed bone meal and fish intestine water, combined with potassium dihydrogen phosphate foliar fertilizer. 2. Special nutritional supplements add fertilizers containing trace elements such as boron and molybdenum to improve flowering quality. Add biostimulants such as seaweed essence in the first two months of flowering to promote the development of flower arrows. 4. Assisted flower promotion technology For plants that are mature for more than 3 years, if they have not bloomed under regular maintenance, gibberellin (concentration 50-100ppm) can be used for flower promotion treatment. Pay attention to the dilution ratio of the agent, use the root irrigation method once a week, and use it no more than 3 times in a row. The effect is better when combined with dark treatment (16 hours a day to block light).
Mastering the three core elements of light, temperature difference, and nutrition, and with scientific auxiliary means, even novices can successfully cultivate flowering clivia. It is recommended to carry out systematic maintenance adjustments every autumn to keep the plant materials loose and breathable, and regularly rotate the flowerpot to ensure uniform light reception, so that this "gentleman among flowers" can bloom with gorgeous flowers as scheduled.
