Why can't Anthurium grow tall?
Anthurium is deeply loved by flower lovers for its bright Buddha spaths and straight flower shapes, but many people find that the plant grows slowly and has a short plant type during the maintenance process. What is the reason why Anthurium cannot grow tall normally? This article will analyze the problem of dwarf anthurium through three core elements and provide professional solutions. Improper light control affects development. A typical manifestation of insufficient light. Although Anthurium is a semi-negative plant, it needs to receive more than 4 hours of scattered light every day during the growth period. When exposed to light below 1000lux for a long time, growth inhibition such as leaf color fading, internodes shortening, and new leaves being smaller than old leaves will gradually appear. The scientific light filling implementation plan recommends placing the plants on the east or north facing window sills and using sunshade nets to filter the noon light. In winter, plant fill light can be used to keep the light intensity between 5000-10000lux. Rotate the flowerpot regularly to ensure uniform light reception and avoid off-crown growth. Temperature fluctuations restrict growth rate and temperature-sensitive characteristics analysis The optimal growth temperature of Anthurium is 18-28℃. When the environmental temperature is lower than 15℃, root activity will be reduced and nutrient absorption will be blocked; when the environmental temperature exceeds 32℃, heat stress will occur, and dual temperature stress will inhibit vertical growth of plants. Practical tips for temperature control throughout the year use spray to cool down and strengthen ventilation to maintain air flow in summer, and use heating pads to maintain substrate temperature in winter. Controlling the temperature difference between day and night at 5-8 ° C can promote material accumulation, and using a temperature and hygrometer to monitor environmental parameters in real time. Imbalanced water and fertilizer management limits development, nutrient deficiency, identification characteristics, leaves yellowing and becoming smaller when nitrogen deficiency, and phosphorus deficiency causes poor root development. Excessive watering will lead to high EC values of the substrate, which will lead to salt-damaging dwarfing. It is recommended to use a TDS pen to regularly detect the concentration of soil solution, and it is advisable to control it at 800-1200μS/cm. The precise fertilization and watering plan adopts the watering principle of "seeing wet when it is dry" and is combined with siphon-type self-absorbent flowerpots. Balanced fertilizer with N-P-K=20-20-20 is applied every half of the month during the growth period, and trace element fertilizer containing calcium and magnesium is added during the flowering period. Pay special attention to avoid fertilizer solution contaminating leaf surfaces and causing burns.
By systematically regulating the four major elements of light, warm water and fertilizer, and coordinating with maintenance measures such as regular pot changes and root pruning, Anthurium plants can return to normal growth rhythm within 3-6 months. It is recommended to take growth comparison charts every quarter and establish a maintenance log to continuously optimize management plan.
