How to fertilize dahlias
1. When fertilizing, we should not only pay attention to the amount of nitrogen. If we ignore this problem, dahlia may have only leaves and flowers p>
2. Attention should be paid to dressing fertilizer. Topdressing should be stopped in high temperature season (above 30 ℃ in summer), and normal topdressing can be carried out only when the temperature drops in autumn p>
3. Dahlia has a good ability to absorb fertilizer, but because of this, topdressing can not be excessive, and its stems and leaves can grow just right. Although there should be sufficient fertilizer, otherwise Dahlia will bloom smaller, the color is not plump, and it is not so beautiful. Secondly, according to its growth, decide whether to topcoat or not. It's best to pour some thin fertilizer p>
4. At first, the seedlings are generally applied with low concentration liquid fertilizer for about half a month. Once every 7-10 days after the emergence of flower bud. Fertilization should be stopped when flower buds appear. The amount of fertilizer depends on the growth of the plant. If the leaf color is not deep, it is time to apply fertilizer; However, if the leaves turn yellow, it is caused by too much non fertilizer. At this time, fertilization should be suspended p>
5. After the emergence of flower buds, liquid fertilizer shall be applied three times every month, and the flower bud can be stopped only when it blooms slightly. The roots of 10cm-15cm should flow out before the frost. Cut off the branches and leaves, dig up roots and dry them for one or two days, and then they can be stored in the house. The temperature in the house is five degrees Celsius p>
