What should I do if the leaves of the dragon spit beads are wilted?
Wilting leaves of Longtuzhu is a common problem that troubles flower lovers. This tropical plant is sensitive to water, light, temperature and other conditions. This article will systematically analyze the causes of leaf wilting through four core maintenance dimensions and provide practical solutions to help you recreate the vitality of Longtuzhu. 1. Scientifically control the typical symptoms of improper watering. When the soil is too wet, the root system will appear black rot due to hypoxia, which will be manifested by curling new leaves and yellowing old leaves; while long-term drought will lead to scorched leaf margins and sagging entire plants. It is recommended to determine soil moisture by bamboo stick testing: observe it 2 hours after inserting the soil. If the bamboo stick is wet, no water is needed. The precise water replenishment strategy uses the "dipping basin method" to replenish water in summer. Put the flower pot into the water basin and soak it for 15 minutes to ensure that the deep soil absorbs water evenly. In winter, long-spout pots are used to pour slowly along the basin wall to avoid freezing damage. In spring and autumn, the principle of "seeing dry, seeing wet" shall be maintained, and water shall be replenished immediately when the topsoil is 2 centimeters dry. 2. Intelligent adjustment of light intensity Remedial measures for excessive light in summer from 10:00 to 15:00, you need to use a sunshade net to filter 50% of the light, or move it to the east-facing balcony. If sunburn spots have occurred, spray 0.1% potassium dihydrogen phosphate solution to enhance leaf resistance. Winter fill light tips Use a full-spectrum plant fill light to fill light for 4 hours a day, with a lamp distance of 40-50 cm. Cooperate with rotating the flowerpot to ensure uniform light reception in all directions. 3. Refined temperature management overwintering protection system The "pot insulation method" can be adopted in the northern region: large flower pots are nested outside the original pots, and the gaps are filled with vermiculite or perlite. Cover with non-woven insulation cover at night to maintain a growth temperature of 12-15℃. Summer cooling plan When spraying is used to cool down during high temperature periods, ventilation needs to be strengthened simultaneously. It is recommended to use circulating fans to maintain air flow while avoiding blowing directly on the plants. 4. Nutritional Diagnosis Guidelines for Scientific Fertilization Plans When old leaves become yellowed when nitrogen is deficient, soybean cake fertilizer needs to be applied; potassium deficiency is manifested by scorched leaf margins, which can be buried and applied with plant ash; if new leaves become yellowed, ferrous sulfate solution needs to be supplemented to adjust the soil pH. The growing season fertilization plan adopts the "3+2" fertilization model from March to September: three times of decomposed rice washing water (diluted 50 times) and two times of potassium dihydrogen phosphate solution (0.2%) are used alternately, with an interval of 10-15 days. Stop fertilizing and cultivate in winter.
By systematically regulating the four major elements of water, light, temperature and fertilizer, and regularly checking leaf conditions, the problem of leaf wilting of Longtuzhu can be effectively prevented and improved. It is recommended to conduct root inspection every month, replace red pottery pots with good air permeability in time, and use a matrix formula of coconut bran + perlite (3:1) to create the best growth environment for Longtuzhu.
