Why do longevity flowers are lush but do not bloom
Many flower friends find that the longevity flowers at home are luxuriant but have not yet bloomed. There are often hidden misunderstandings behind this. This article will provide an in-depth analysis of the key factors affecting flower bud differentiation from four dimensions: light management, nutrient control, pruning skills, and soil optimization, and help you solve the maintenance dilemma of "only growing leaves but not blooming." 1. In-depth analysis of the causes and treatment of excessive plant growth. Excessive growth caused by excessive nitrogen fertilizer will increase the spacing between stems and nodes and consume the nutrients stored by the plant. According to data from the International Horticultural Association, when the ratio of nitrogen, phosphorus and potassium in the substrate is unbalanced to 5:1:1, the flowering rate drops by 73%. It is recommended to use 20-20-20 balanced fertilizer combined with picking treatment. Practical Guide for Scientific pruning Conduct heavy pruning in late spring and early summer, retaining the base 2-3 pairs of leaves. When the new branches reach 5 cm, they will be picked immediately, and combined with 180° pot rotation every week, the plant type can be evenly shaped. The pruning tools need to be disinfected with 75% alcohol, and the incision should be coated with charcoal powder to prevent infection. 2. The core technology of photoperiod control experiments with precise control of light duration have proved that 8 hours of direct light +16 hours of dark treatment per day for 6 consecutive weeks can induce 95% of plants to appear buds. It is recommended to use a smart fill light to set light for 4 hours in the morning and dusk, and cover the shade at noon to avoid burns above 35℃. 3. Optimize the nutrient supply system and scientific ratio plan for flower promotion fertilizers. During the flower bud differentiation period (October to November), spray 0.2% potassium dihydrogen phosphate on the leaves every week, combined with root application of decomposed bone meal. Pay attention to avoid nitrogen fertilizers such as urea, and the EC value should be controlled at 1.2-1.8mS/cm. 4. The substrate improvement system project recommends replacing the substrate in early spring every year and preparing it according to peat: perlite: vermiculite =5:3:2. Add 5% pine scale to improve air permeability, and mix in slow-release fertilizer as base fertilizer. Regularly test the pH value and maintain it in a slightly acidic environment of 6.0-6.5.
By systematically regulating the four major elements of light, nutrition, pruning, and substrate, and combining with temperature and humidity management, the flowering volume of longevity flowers can be increased by more than three times. It is recommended to establish a maintenance log to record the time of each pruning and fertilization, and gradually grasp the growth laws of plants.
