How to fertilize pomegranate flowers

Fertilization type

base fertilizer

The types of base fertilizer in summer are mainly organic fertilizer, and it is best to apply it in May. Because the roots and fruits are growing well at this time, and the branches and leaves are about to stop growing, fertilizing at this time will not cause a second growth. After fertilizing, water it, and the soil, fertilizer, and root system will be closely connected, which will promote the absorption of fertilizer.

Autumn base fertilizer should be applied after the fruit is harvested. At this time, the root system is in the growth period, and even if the roots are injured, they will heal quickly. When applying fertilizer, you can cut off some of the small roots, which can have the effect of pruning the roots and promote the growth of new roots. In terms of the proportion of fertilizers, nitrogen fertilizer can be appropriately increased to promote the growth of branches and leaves.

top dressing

Top dressing before flowering: Top dressing in early May, mainly choose nitrogen, phosphorus and potassium fertilizers. Timely top dressing can meet the needs of the plant for flowering and fruiting.

Top dressing after the flowers fall: Top dressing is needed in time after the pomegranate flowers fall. This is the period when the pomegranate needs the most fertilizer. The development of young fruits and the growth of new shoots require sufficient nutrients. At this time, appropriately increasing nitrogen fertilizer can reduce physiological fruit drop. If a large amount of topdressing is applied before flowering, the amount of fertilizer can be reduced appropriately after flowering.

Fertilization method

Shallow trench fertilization

Dig a deep circular trench around the outermost edge of the flowerpot, add fertilizer into it, and then cover it with soil. Be careful not to cut off the pomegranate roots when digging the soil. This method is suitable for pomegranate seedlings.

Hole fertilization

Dig a small hole about 20 cm deep directly next to the pomegranate, pour the fertilizer into it, and then cover it with soil.

Foliar Fertilizer

This method is simple and easy, requires less fertilizer, and takes effect quickly. Mainly dilute the fertilizer and spray it on the leaves. Obvious absorption will be seen 10-15 days after spraying. This method can improve the nutritional status of the roots, promote the development of the root system, and enhance the absorption capacity. However, foliar fertilization cannot replace soil fertilization. The two should complement each other.

However, the best time to apply foliar fertilizer is before 10 a.m. and after 4 p.m. Try to spray when the temperature is moderate and the sunlight is not strong.
