What fertilizer is best for camellia

Camellia fertilization time

Camellia needs to be fertilized during its growth period, which can be done around February to March in spring, around May to June in summer, and between October and November in autumn.

In spring, in order to increase the germination rate of camellia, more phosphorus and potassium fertilizers and less nitrogen fertilizers should be applied. If the camellia is mainly for plant growth, nitrogen fertilizers can still be applied, but no phosphorus fertilizers should be applied. Every 10 days or so, diluted potassium dihydrogen phosphate, a small amount of borax and rice vinegar can be sprayed on the leaves.

What fertilizer is good for camellia

1. Organic fertilizer : When planting or repotting camellia, you can add decomposed bean cake water or fish bone meal to the soil, which can continuously provide nutrients for the growth of the plant and promote its growth and flowering.

2. Liquid fertilizer : Camellia needs an appropriate amount of fertilizer during its growth period. You can make fertilizer from rice water, bean cakes, fish heads, etc. It needs to be diluted with water before use, so that the flowers and leaves will be brighter in color.

Camellia fertilization method

Camellia usually starts to be shaded at around 18℃, and nitrogen fertilizer can be applied every 10 days until the spring buds begin to lignify. If you want it to grow more buds, you should apply more phosphorus and potassium fertilizers, and no or less nitrogen fertilizer.

In summer, the weather is hot and camellia grows slowly, so it is not suitable to fertilize at this time. Autumn is the period for it to accumulate nutrients. You can apply a mixed fertilizer containing phosphorus and potassium fertilizers at intervals of 15 days and combine it with foliar spraying to promote plant health and improve its cold resistance. In winter, it enters a semi-dormant period, and you can apply dilute liquid phosphorus and potassium fertilizers when watering.

Matters Needing Attention in Fertilizing Camellia

During the flowering period of camellia, you must not fertilize it, otherwise it will cause the flowers and buds to fall off. During the high temperatures in summer and the semi-dormant period in winter, you need to reduce or stop fertilizing, otherwise it will cause the roots of the plant to rot.
