That is to say, the fertilizer applied to the soil before the plant is planted. If you plant plants on the ground surface, you can mix the fertilizer and soil evenly, sprinkle it on the ground, cover it with a layer of soil, and then plant seedlings; if you plant plants in a pot, you can directly spread the fertilizer into the lower part of the flowerpot, and cover it with soil. No matter outdoors or indoors, do not let the root of the plant touch the fertilizer directly.
Base fertilizer can also be used to change pots for plants, and the method of base fertilizer is preferred by the old florists, while the new florists are more inclined to the method of top dressing
I agree with you that it is to apply fertilizer to plants during their growth period, but it is called topdressing. When topdressing, try not to put the fertilizer near the root. Avoid burning plants. Loosen soil and water in time after fertilization.
Before applying fertilizer, we should have a necessary understanding of plants. Different plants, different periods, apply different fertilizers. At the same time, we should apply fertilizer according to our own plant conditions. Season is also a factor in fertilization. Although there are clear fertilization methods on the purchased fertilizer, they should also be determined according to the situation of their own plants. The longest way to apply fertilizer is to apply a small amount of fertilizer more often. It's better to apply a small amount of fertilizer each time and apply more fertilizer several times. It's not too convenient to apply too much fertilizer. So as not to burn the root system. Cause unnecessary damage to plants.
