Aloe fertilization method
As a star variety among succulent plants, aloe vera is deeply loved by gardening enthusiasts for its unique shape and practical value. Scientific fertilization is the key link to cultivate high-quality aloe vera with thick leaves and full plant type. This article will systematically analyze the full-cycle nutritional management plan for aloe vera from fertilizer selection to application skills. Scientific fertilization time node: During the basic nutrition period, base fertilizer needs to be added when changing pots in spring. It is recommended to add bone meal or decomposed fish meal at a ratio of 1:10 when mixing the substrate to establish a nutrient reserve for the root system. Fertilizing at this time can prevent new roots from coming into direct contact with high-concentration fertilizers. During the peak growth season, topdressing period is from April to September. During the vigorous growth period, nutrients are replenished every 15 days. Observe the unfolding speed of new leaves. When no new leaves appear at an interval of more than 2 weeks, topdressing is needed in time. The golden rule for fertilizer selection is organic and inorganic combination principles. The basic fertilizer is preferably decomposed sheep manure (nitrogen, phosphorus and potassium 1.5:1.2:0.8) and earthworm manure, and the topdressing can use water-soluble compound fertilizer (N-P-K=5-10-10). In the rainy season, it is recommended to use granular slow-release fertilizers to prevent nutrient loss. Supplementary plan for special needs: apply potassium dihydrogen phosphate (diluted 800 times) to flowering varieties before budding, and add seaweed essence to medicinal varieties to increase the content of active substances. Be aware that excessive nitrogen fertilizer will cause leaves to grow and thin. Correct fertilization steps and analysis of basic fertilizer application techniques. Fully mix the pretreated fertilizer with perlite, vermiculite and other substrates, and lay a 3-cm-thick buffer layer on the bottom of the basin. Do not allow fertilizer to come into direct contact with the main root, and must be thoroughly watered with root-fixing water after planting. Top dressing operation points apply solid fertilizer along the circular ditch along the edge of the pot, with a depth of about 5cm; liquid fertilizer is mixed with water at 1:1500 to irrigate the roots. Ventilation needs to be strengthened after fertilization in the high temperature season in summer to prevent fertilizer liquid from staying in the heart of the leaves. Maintenance taboos and precautions should be selected for fertilization periods. Select sunny weather with a temperature of 18-25℃. The best time is 9-10 a.m. or 4-5 p.m. When it is below 10℃ in winter, fertilization should be completely stopped. Newly purchased plants under special conditions need to go through a 2-month pot serving period before applying fertilizer. Fertilizer supply should be resumed at an interval of 3 weeks after roots pruning and pot changing. If the leaf tips appear to be scorched, it is necessary to stop fertilizer and wash the roots immediately.
By mastering the core principle of "applying thin fertilizer and frequently" and combining with the scientific ratio of nitrogen, phosphorus and potassium, aloe vera can maintain its best growth state. It is recommended to establish a fertilization log to record the type, amount and plant response of each fertilizer, and gradually form a personalized maintenance plan. Reasonable fertilization can not only promote the healthy growth of aloe vera, but also enhance its disease resistance and extend the viewing cycle.
