The fertilizer used by Dahua Huilan can be some farmyard fertilizer, but it must be mature, at least for one year. Then add 10 to 20 times of water to dilute the fertilizer solution and then use it for watering. It is recommended to sprinkle it on the edge of the flowerpot, and do not touch the roots or leaves.
First of all, it's better to apply fertilizer many times, with less material each time. For example, it can be used once in 10 to 15 days. Then, it is better to spray fertilizer on the leaf surface, especially in the stage of growth and development. Generally, you can spray fertilizer on the leaf once every ten days, and you can use aloe or 1000 times of boron. Of course, the natural organic fertilizer is the best, more moderate and can also avoid soil hardening.
The plants in the growing period can be concentrated once every 14 days. When they are about to bloom, they can use the concentrated liquid fertilizer of flower type, and use it again after flowering. During the vegetative growth period from January to June, some ammonia fertilizer can be added with appropriate potassium fertilizer. From June to October, when we are in the reproductive period, we need to add some phosphorus and potassium fertilizers, and the amount of ammonia fertilizer will be reduced appropriately. From March to September, use more nitrogen fertilizer, and in October, you can add potassium fertilizer, or some special fertilizer for orchids. After flowering in April and may, and in autumn and September, you can apply a little bit of cake fertilizer that has been retreaded once or twice.
