How to fertilize the cultivation of herbaceous flowers

The fertilization technology of flower breeding is different from that of cultivating ornamental flowers, and the main characteristics are as follows:

1. No fertilizer can be applied during the seedling period.

Before raising seedlings, it is best not to use fertilizers such as chemical fertilizers and base fertilizers, lest the proportion of nitrogen, phosphorus and potassium is difficult to control and lead to the death of burning seedlings.

2foliar fertilizer spraying was carried out two or three weeks after transplanting seedlings.

Mainly spray potassium dihydrogen phosphate or some production enhancers and so on. The application of nitrogen fertilizer depends on the type. Calendula, violet and goldfish grass can be properly topdressing or spraying a small amount of N fertilizer 3 weeks before seedling transfer, and phosphorus and potassium fertilizer should be applied 3 weeks after transplanting. Red and zinnia should not be applied in the whole growing period, otherwise there will be no harvest.
