Aloe needs the amount of nutrients, especially the amount of nitrogen, phosphorus and potassium greatly exceeds the amount that the potted substrate can provide, so it needs to be supplemented with fertilizer. In addition, boron, manganese, molybdenum, zinc, copper, chlorine and other elements are needed during the growth of aloe, and it is sometimes necessary to supplement the growth of potted aloe.
The commonly used fertilizers for potted aloe are: organic fertilizers, organic fertilizers are rich in organic substances, nutrient content is relatively comprehensive, is a complete fertilizer, but the fertilizer is slow, generally used as potted aloe base fertilizer. Cake fat, that is, oily cypress after oil extraction of various vegetable oil-containing fruits, has a high nitrogen content and is easily absorbed by plants. It is a high-quality fertilizer for potted aloe plants in the family and can generally be formulated as a liquid fertilizer and is immersed in 10 times water. Fermentation and application of fertilizer solution with water are effective. Inorganic fertilizers are often used as a top-dressing fertilizer for potted aloes, but long-term use will result in potted soil consolidation, preferably in combination with organic fertilizers.
The fertilization method for potted aloe is mainly based on basal fertilizer and top dressing. The basal fertilizer is prepared by mixing the fertilizer and the substrate before loading the basal, generally the ratio of the substrate and the organic fertilizer is about 10:1, mix well, and then put together in the pot. When the organic fertilizer is used as the base fertilizer, it must be fully fermented in advance. , otherwise there will be a phenomenon of burning seedlings.
Top dressing is carried out during agro-planting period after the pot is filled. The top dressing is diluted with fertilizer and then applied. Generally, no more than 2% urea or 1% of superphosphate calcium aqueous solution is used for pouring. When topdressing, the fertilizer solution should not be too thick, otherwise it will produce fertilizer damage, especially when using foliar spray outside the root dressing fertilizer, the fertilizer concentration shall not exceed 1%, top dressing can generally be performed every 20 to 30 days, Can also be based on the growth of aloe and different seasons of topdressing, generally faster growth in the spring, you can increase the number of appropriate fertilizer, the winter growth is slow, you can use less fertilizer, or even no fertilizer.
Moderate fertilization is beneficial and harmless. For fertilizers, organic fertilizers such as bean cake and chicken manure are all suitable. The fertilization period can be once every two months. Since the root activity is suspended between November and March, fertilization should be avoided.
