What Fertilizer to Use for Succulents
Among numerous potted plants, succulents are loved for their unique shapes and low maintenance characteristics. Scientific fertilization is a crucial part of maintaining the healthy growth of succulents, as it needs to meet their nutritional needs while avoiding the risks of fertilizer damage. Mastering the correct fertilization method can help your succulents display their best state.
Key Elements of Fertilizing Succulents
Optimal Fertilization Schedule Planning
The spring and autumn seasons (March-May, September-November) are the peak growing periods for succulents, and it is recommended to supplement nutrients every 4 weeks. During the high-temperature summer (temperatures above 32°C) and the low-temperature winter (temperatures below
In-depth Analysis of Fertilizer Types
Succulent-specific fertilizer (N-P-K=5-10-5) contains slow-release granules, providing continuous nutrients for up to 3 months. Organic fertilizers need to be fully decomposed, and sheep manure fertilizer EC values should be less than 1.2mS/cm, requiring sunlight exposure and disinfection before use. Foliar fertilizers recommend a 0.1% potassium dihydrogen phosphate solution, sprayed twice a month, with better results when combined with LED supplemental lighting.
Precise Fertilization Operation Guide
Base fertilizer should be mixed with the substrate at a 1:10 ratio and placed at the bottom when repotting. Liquid fertilizer needs to be diluted 800-1000 times and poured slowly along the pot edges. Solid slow-release fertilizer should use 5-8 granules for every 10cm pot diameter, buried 1cm deep in the surface. Foliar spraying should avoid midday intense sunlight, with higher atomization providing better absorption.
Prevention and Treatment of Fertilizer Damage
If you notice that the leaves are becoming transparent or the base is turning black, stop fertilizing immediately and water the roots with clean water three times in a row. For severe root burn, trim the roots and soak them in NAA rooting solution (50ppm) for 1 hour, then let them dry for 3 days before replanting in new soil. It is recommended to have an EC testing pen to maintain soil conductivity within a safe range of 0.4-0.8mS/cm.
By scientifically proportioning fertilizers and precisely controlling the fertilization rhythm, succulents can maintain a compact growth habit and vibrant colors. It is recommended to keep a fertilization log, recording the time, type of fertilizer used, and the plant's response, gradually mastering the fertilization needs of different varieties. Combined with proper lighting and ventilation, the effects of fertilization can be maximized.
