What should I do if the leaves of the money tree fall off?
As a star variety among succulent plants, money wood is deeply loved for its thick leaves and rich meaning. However, many flower friends have found that the leaves of the money wood suddenly turn yellow and fall off, which is often closely related to improper daily maintenance. This article will systematically analyze the three major causes of leaf loss of money trees and provide practical treatment plans. There are three major causes of leaf loss of money wood 1. Imbalanced water management causes more than 60% of leaf loss cases of rotten roots due to improper watering. Money wood has massive water-storing roots. Excessive watering will lead to hypoxia and rot in the roots, which is manifested in the fact that the lower leaves become soft and fall off first. It is recommended to use the "three-finger test method": insert your fingers into the soil three fingers deep, completely dry before pouring through water. 2. Temperature fluctuations affect metabolism. The temperature difference between day and night exceeds 8 ° C or the low temperature environment in winter will trigger the plant protection mechanism to actively fall leaves. Experimental data shows that when the temperature is less than 15 ° C, the shedding rate of golden wood leaves is increased by x times, and special attention should be paid to the constant temperature for the maintenance of air-conditioned rooms. 3. Chain reaction of pests and diseases After sucking on the juice, pests such as scale insects and red spiders will leave yellow spots on the leaves and induce coal pollution disease. Infected leaves will wilter quickly within 48 hours and need immediate isolation. The four-step rescue method reproduces the vitality of the golden tree. The precise irrigation technique uses the "dry and wet cycle method" in spring and summer, and the basin soil is completely dried before pouring it through; in winter, it is changed to the "trace water replenishment method", and 50ml of clear water is injected along the basin edge every month. The use of pottery pots can improve the air permeability by 30%, effectively preventing water accumulation. The intelligent temperature control plan adopts a "triple insulation method" in winter: foam board on the bottom of the basin + insulation cover + away from window seams. When the room temperature is less than 10℃, plant heating pads can be temporarily used to maintain the root temperature above 15℃. Scientific lighting configuration of money wood requires a light intensity of 20000-30000Lux. You can use a plant fill light to fill the light for 4 hours a day. In summer, you need to filter 50% strong light with a sunshade net to avoid leaf burns and forming brown spots. Insect pests found in integrated pest control were immediately physically removed with 75% alcohol cotton flakes and sprayed with azadirachtin biopesticide. Wipe the leaves with garlic extract (1:10 dilution) every week to form a natural protective film. The golden rule for advanced maintenance money wood has the characteristics of "three fears and three joys": it is afraid of low temperatures and likes warmth, it is afraid of humidity and likes drying, and it is afraid of darkness and likes scattering light. It is recommended to replace the granular soil (red jade soil: volcanic rock: peat =5:3:2) every two years, and applying slow-release fertilizer in spring and autumn can increase the thickness of leaf wax layer. Master these maintenance tips and your money wood will maintain its emerald luster all year round.
