How to make and use camellia fertilizer

Camellia suitable fertilizer

Commonly used fertilizers for camellia are nitrogen fertilizer and potassium dihydrogen phosphate. Generally, you cannot use only one fertilizer. You can apply nitrogen fertilizer and potassium dihydrogen phosphate alternately, which can promote vigorous growth of the plants and provide the necessary nutrients for the differentiation of flower buds.

Organic fertilizers are the most suitable for camellia, such as bean cake crumbs, fish bone meal, and fermented and rotten fish and poultry manure. These fertilizers are all natural and contain sufficient nutrients to meet the nutrients needed for camellia growth.

Camellia flower fertilizer production method

1. Homemade nitrogen fertilizer

Crush and boil moldy beans, peanuts, melon seeds, castor beans, or leftover vegetable leaves, bean shells, melon and fruit peels, or pigeon droppings. Put them all in a small jar, fill it with water, seal it, and leave it for a while to ferment and decompose.

2. Homemade phosphate fertilizer

Pour leftover pig bones, discarded fish intestines, poultry feces, fish bones, etc. into a jar and add an appropriate amount of fermentation agent, add a small amount of water, seal it well, and after a month of fermentation, it can be diluted with water for use.

How to use camellia fertilizer

1. Fertilizing the spring shoots: After the spring, as the temperature continues to rise, camellia will begin to sprout spring shoots. At this time, it needs to be fertilized to promote germination, usually once every 10 days. The fertilizer should be mainly nitrogen fertilizer, and it should be applied until the spring shoots become lignified. In addition, you can also spray some foliar fertilizer, usually potassium dihydrogen phosphate mixed with urea and rice vinegar.

2. Fertilization before flowering: During the flower bud differentiation period of camellia, it is necessary to control the amount of nitrogen fertilizer and apply phosphorus and potassium fertilizer instead. This can prevent the plant from growing too tall, shorten the differentiation time, and promote the formation of flower buds. It is usually applied once every 10 days. Fertilizer is mostly potassium dihydrogen phosphate, add a little borax and rice vinegar, dilute it and spray it on the leaves.

3. Fertilization in autumn: The temperature begins to drop in autumn, but this is the period of nutrient accumulation, so it is also necessary to apply fertilizer appropriately, generally once every 15 days. Fertilizers should still be phosphorus and potassium fertilizers, which can not only supplement nutrients, but also improve the plant's cold resistance and help it survive the winter better.

Too much camellia fertilizer

If camellia uses too much fertilizer and loses leaves, you can repot or prune the plants. You can also re-root or graft them to allow the plants to grow again.

Matters Needing Attention When Fertilizing Camellia

1. Camellia will enter a dormant state in the summer, so it is not suitable to fertilize it at this time. Although it will also be semi-dormant in the winter, its growth has not completely stopped. Therefore, in order for the plant to bloom better, it is still necessary to add fertilizer, but it should be combined with watering to reduce the concentration of fertilizer.

2. Do not apply fertilizer during the flowering period of camellia, otherwise it will cause the flowers and buds to fall off. If you see that the branches of the camellia are growing too long and the leaves are dark green, it means that too much fertilizer has been applied and you must stop fertilizing immediately.
