How to Fertilize the刺梅 and How Much
As a star variety among succulent plants,刺梅 is deeply loved by gardening enthusiasts for its unique shape. To maintain the vigorous growth of 刺梅, scientific fertilization is a key factor. This article will systematically analyze the complete knowledge system of 刺梅 fertilization and maintenance from three dimensions: fertilizer selection, application frequency, and operational skills.
Three Core Elements of Fertilizing 刺梅
1. Fertilization Cycle Control Techniques
During the growing period of 刺梅 (March-October), it is recommended to apply thin fertilizer every 15-20 days, and extend to 45 days/interval during the winter dormancy period. Specific needs should be adjusted according to the plant's condition: during the period of new leaves expanding, it can be increased to 12-15 days/interval, and the cycle should be appropriately shortened 20 days before flowering. Special attention should be paid to stop fertilizing immediately when the temperature is greater than 32°C or less than 10°C.
2. Fertilizer Ratio Selection Plan
Base fertilizer recommends decomposed sheep manure (3:1 mixed with garden soil), alternating the use of NPK compound fertilizer (20-20-20) and organic liquid fertilizer (diluted 800 times) during the growing period. Change to a high-phosphorus formula (10-30-20) during the budding period, combined with foliar application of potassium dihydrogen phosphate (0.2% concentration).
3. Scientific Application Operational Norms
Solid fertilizers should be applied using the annular trench method, digging a 2cm shallow trench 5cm away from the main stem, applying 3-5g per plant, and then covering with soil. Liquid fertilizers should be poured slowly along the edge of the pot, with each application not exceeding 1/10 of the volume of the potting soil. Ventilation must be ensured within 24 hours after fertilization to prevent fertilizer solution from remaining in the leaf axils.
Precise Control of Fertilization Amount for 刺梅
For adult plants (with a crown diameter greater than 25cm), the single application amount of fertilizer should be controlled between 5-8g, and half for seedlings. Judge the effect of fertilization by the leaf condition: if the leaf color is dark green, the amount of fertilizer is appropriate; if the leaf tip is burnt, stop fertilizing and wash the soil; if the new leaves are less than 2cm, increase the amount of fertilizer. It is recommended to use controlled-release fertilizer (3-month slow-release type) as a supplement.
Mastering the principle of applying thin fertilizer frequently and adjusting the plan according to seasonal changes can keep 刺梅 in the best growth state. Regularly observing the plant's feedback and combining the advantages of organic and chemical fertilizers can effectively prevent fertilizer damage and improve flowering quality. It is recommended to establish a fertilization log, recording the type of fertilizer used, the amount, and the plant's response each time, gradually forming a personalized maintenance plan.
