When to fertilize dahlias

Dahlias can be given some low-concentration liquid fertilizer every half a month after the seedlings emerge, and fertilizer should be applied every 7-10 days after the flower buds appear.

Top dressing can be done every month during the growth period of dahlias, but if the temperature is above 30 degrees in summer, top dressing should be stopped. After the temperature drops in autumn, top dressing can be done normally.

What fertilizer to use for dahlias

During the growth period of dahlia, nitrogen fertilizer is mainly applied, and before flowering, phosphorus and potassium fertilizers are mainly applied. Inorganic fertilizer is applied once every 10 days, and organic fertilizer is applied once every 30 days.

How to fertilize dahlias

When fertilizing dahlias, you cannot just focus on applying nitrogen fertilizer, so as to avoid excessive growth of branches and leaves without blooming. You also need to apply appropriate amounts of fertilizer based on its growth conditions. It is best to use some thin fertilizers. After the flower buds appear, you can apply liquid fertilizer once every 10 days, and stop when the flower buds are slightly open.

Precautions for fertilizing dahlias

Dahlias like fertilizer, but you cannot apply too much fertilizer. The amount of fertilizer used needs to be strictly controlled to avoid fertilizer damage, which is not good for the growth and flowering of the plant. Also, you cannot use raw fertilizer or concentrated fertilizer. The base fertilizer needs to be fully decomposed before use.
