The reason why longevity flowers are lush but do not bloom
The green longevity flower has lush branches and leaves but no buds, which troubles many friends who love gardening. As a popular variety among New Year's Eve flowers, its flowering period could last throughout winter until the following spring. When encountering the embarrassing situation of "only leaves grow but not flowers", it often reflects the existence of key misunderstandings in the maintenance process. This article will start from the three core elements and take you to crack the blooming code of longevity flowers. Nutritional imbalance: The ratio of nitrogen, phosphorus and potassium is unbalanced. The chain reaction of excessive nitrogen fertilizer. The growth model of longevity flowers is divided into two stages: vegetative growth and reproductive growth. When the nitrogen content in the soil exceeds the standard, the plant will continue to undergo vegetative growth, which is characterized by thick leaves, thick stems, but no flower bud differentiation. Experimental data shows that when the ratio of nitrogen, phosphorus and potassium exceeds 3:1:1, the flowering rate drops by more than 60%. The scientific fertilization solution recommends switching to phosphorus-potassium compound fertilizer during the bud pregnancy period, and spraying potassium dihydrogen phosphate solution (diluted 1000 times) to leaf surfaces every week. At the same time, bone meal or seaweed fertilizer is applied to the roots to promote flower bud formation. Special attention should be paid: Avoid direct light within 48 hours after fertilization. Light regulation: Photoperiod and intensity control photoperiod management key to short-day plants. Long-lived flowers need 6-8 hours of darkness every day to induce flowering. During autumn maintenance, artificial shading (5 p.m. to 8 p.m. the next day) can create a continuous dark environment for 14 hours, and flower buds can be seen after 4-6 weeks. The light uniformity adjustment adopts a 360° rotation maintenance method, and the flowerpot is rotated 90 degrees clockwise every 3 days. Use a light meter to monitor and keep the light intensity between 8000 and 12000lux. It is recommended to use a 50% sunshade net for southbound window sills to avoid strong light burning the leaves. Temperature management: Creating skills for day and night temperature difference The ideal temperature range is maintained at 18-25℃ during the day and at 12-15℃ at night. The temperature difference of 5-8℃ can effectively stimulate flower bud differentiation. When the temperature continues to be higher than 28℃, the plant will enter a dormant state. At this time, fertilization should be stopped and watering should be reduced. Prevention measures for cold damage Winter maintenance needs to ensure that the ambient temperature is not lower than 5 ° C. Double-layer insulation method can be used: the inner layer is covered with a transparent plastic bag (leaving ventilation holes), and the outer layer is covered with non-woven fabrics. Remove the cover before 10 a.m. to ensure normal photosynthesis.
By accurately controlling the three major maintenance factors, more than 90% of longevity flowers can regain their flower appearance within 30-45 days. It is recommended to conduct soil EC value testing every month to keep the medium conductivity between 1.2-1.8mS/cm. When a blush is found on the edge of new leaves, it is a precursor to flower bud differentiation, and the supply of phosphate fertilizer should be increased at this time. Mastering these key skills will surely make your longevity flowers full year after year.
