1. When applying fertilizer, we can't only pay attention to the amount of nitrogen. If we ignore this problem, dahlia may only have leaves and flowers can't bloom.
2. Pay attention to the application of fertilizer. High temperature season (summer 30 degrees Celsius above) to stop topdressing, autumn when the temperature drops before normal topdressing.
3. Dahlia has a good absorption capacity for fertilizer, but because of this, topdressing cannot be excessive, and its stems and leaves can grow just right. Although there should be sufficient fertilizer, otherwise dahlias will come out smaller, not plump in color, not so beautiful. Second, according to its growth situation, it is better to apply fertilizer thinly.
4. In the first half of a month or so, the seedlings are generally added with a low concentration of liquid fertilizer. Once every 7-10 days after emergence of flower bud. Stop fertilizing when the buds appear. The amount of fertilizer depends on the growth of the plant. Where the leaf color is not deep, it should be fertilized; but if the leaf is yellow, it is caused by too much, at this time, fertilization should be suspended.
5. After the flower bud appears, liquid fertilizer should be applied three times a month, and the flower bud can stop when it is slightly blooming. The roots of 10cm-15cm should flow out before the frost, cut off the branches and leaves, dig up the roots, air for one or two days, and then put them in the house for storage. The temperature in the house is five degrees centigrade right.
Even the plants that like fertilizer can't be fertilized too much. The more they absorb fertilizer, the more they can't take it lightly. The more fertilizer they need, the more strict they need to control. The flower friends will learn slowly in practice in the future.
