Hydrangea Fertilizer

Hydrangeas like fertilizer, and commonly used flower fertilizers are usually some acidic fertilizers. If it is base fertilizer, commonly used fertilizers include slow-release fertilizer, organic fertilizer, bone meal, cake fertilizer, etc. Top dressing can be with nutrient solution, various liquid fertilizers, etc.

It is more appropriate to use nitrogen fertilizer in the early stage of hydrangea. You can apply decomposed alum fertilizer water to it, and you also need to apply urea to it, which is conducive to its vigorous growth. If it is in the flower bud differentiation and bud formation period of hydrangea, then applying phosphorus and potassium fertilizers is the most appropriate. You can spray potassium dihydrogen phosphate on the leaves 2 to 3 times, and stop fertilizing after the buds are translucent.

How to make hydrangea fertilizer

Use banana peels to make flower fertilizer: Banana peels cannot be mixed directly into potting soil. They need to be fermented and decomposed. A better way is to mash the banana peels, soak the peels in a container, and then filter out the residue with a gauze. The resulting solution can be diluted with water and used.

How to use hydrangea fertilizer

1. Base fertilizer: When planting hydrangeas, it is generally necessary to mix base fertilizer into the soil. Usually, for a 20-caliber flower pot, mix 2g of slow-release fertilizer into the soil, or grab a handful of organic fertilizer. The smaller the flower pot, the less soil it can hold, and the less fertilizer is needed.

2. Topdressing: During the growth period of hydrangea, quick-acting fertilizer can generally be poured into the soil. Usually, diluted liquid fertilizer should be poured into the soil once every half a month. During the growth period, liquid fertilizer with balanced nitrogen, phosphorus and potassium should be applied to promote growth, and phosphorus and potassium fertilizers should be used before flowering to promote flowering.

Too much fertilizer for hydrangea

If hydrangeas lose leaves due to overfertilization, but the situation is not too serious, you can immediately pour plenty of clean water into the hydrangea pot to dilute the excess fertilizer.

If the situation is serious, you should immediately remove the plant from the pot and wash the roots, remove the rotten roots, wash them, soak them in a solution of carbendazim, then air the roots for two hours, prepare new potting soil and repot them.

Precautions for fertilizing hydrangea

When fertilizing hydrangeas, you must control the amount of fertilizer and do not let the fertilizer come into direct contact with the root system to avoid affecting the growth of the plant by damaging the root system. You also need to pay attention to applying thin fertilizers frequently to prevent the hydrangea from overfertilizing and burning the roots.
