How to grow cornflowers in spring

1. Proper pruning

The purpose of spring pruning is to promote the growth of new branches and concentrate nutrients. When pruning, you first need to cut off the top of the most luxuriant main branch to avoid apical dominance. If the side buds grow too densely, they need to be combed slightly to concentrate nutrients.

2. Increase nutrients

Spring is its growing season, and its consumption of nutrients is particularly high. The nutrients in the soil alone are not enough to meet its needs. If it is a newly planted plant, because there is already base fertilizer in the soil, the interval between fertilization needs to be increased to avoid fertilizer damage. Old plants need to be fertilized once every 15 days, and low-efficiency fertilizers should be used to avoid fertilizer damage.

3. Resume watering

The plant needs more water during the growing period and needs to be watered daily. The temperature in late spring is relatively high, and daily watering cannot meet its needs. It needs to be watered every morning and evening, that is, twice a day. You don't need to water too much, just make sure the soil is completely moist without any water accumulation.

4. Enhance lighting

In spring, cornflowers have a relatively high demand for sunlight and must be exposed to the sun for at least five hours a day. The light in late spring is relatively strong. Normal light is available in the morning and afternoon, but the sunlight is too strong at noon and appropriate shade is needed.
