Beer contains a large amount of carbon dioxide, which is an indispensable substance for the metabolism of various plants and flowers; Beer also contains nutrients such as sugar, protein, amino acids, and phosphates, which are beneficial for flower growth. Usage: Press with water and beer:

The proportion is evenly mixed and poured directly, which can make the flowers grow vigorously and the leaves are green and gorgeous. After mixing water and beer evenly in the ratio of :, spraying the leaves, the effect of extra-root fertilization can also be obtained.

Hydrangeas like fertilizer, if you want the plant to bloom into blue-purple flowers, you can apply some acidic fertilizer, you can apply base fertilizer when planting hydrangea, and the bottom fertilizer can be slow-release fertilizer, organic fertilizer, bone meal, cake fertilizer, etc. This type of fertilizer can provide nutrients to the plants slowly, as long as you use the amount of fertilizer well and do not allow the fertilizer to come into direct contact with the root system. In the growth period of the plant, some liquid fertilizer can be applied to top dressing, and top dressing can be used with nutrient solution, various liquid fertilizers, etc.

This kind of fertilizer can provide nutrients for hydrangeas quickly, but it should be applied diligently to prevent hydrangea hypertrophy and burn roots.

It is best not to fertilize hydrangea during flowering, if the fertilization is improper, it may lead to fertilizer damage, causing the root system to be burned out, resulting in a shortened flowering period, and the flowers wither in advance.

If you want to fertilize during the flowering period, you can apply a little thin phosphorus and potassium fertilizer to promote vigorous flowering, pay attention to the nitrogen fertilizer can no longer be applied at this time, and also pay attention to the concentration of fertilizer. In addition to root fertilization, potassium dihydrogen phosphate solution can also be sprayed to promote the flourishing of branches and foliage, and promote flowering.

Fertilization method: You can choose organic fertilizer or chemical fertilizer, it is recommended to use organic fertilizer. You can use well-rotted compost or organic fertilizers such as chicken manure, or you can choose special hydrangea fertilizers.

Fertilization is spread evenly over the soil around the hydrangeas and then thoroughly watered with water to facilitate the penetration of the fertilizer into the soil.

Precautions: When fertilizing, the fertilizer should not be in direct contact with the roots of the hydrangea to avoid burning the roots, and the fertilizer should be sprinkled on the soil around the plant. At the same time, it is also necessary to avoid excessive fertilization, otherwise it may cause hydrangeas to grow too vigorously and affect flowering.

Supplemental nutrition: If you find that the hydrangea leaves are sold to cause malnutrition such as yellowing and smaller leaves, you can consider adding some foliar fertilizer or trace element fertilizer at the same time as fertilization to help hydrangea supplement the nutrients needed.

In conclusion, reasonable fertilization can promote the growth and flowering of hydrangea with tall flowers, but it is necessary to pay attention to the appropriate, uniform and timely fertilization to avoid negative effects on the plants.

Usually, it is mainly nitrogen, phosphorus and potassium compound fertilizer at least twice a month, and when it comes to flowering, it is necessary to stop ternary compound fertilizer, but to use diluted potassium dihydrogen phosphate water-soluble fertilizer, which can not burn the roots but also strengthen the roots, which is more conducive to the absorption of the roots.

In summer, when the temperature is high, you need to stop fertilizing, do not apply thick fertilizer, raw fertilizer, when it is lower than 28 degrees, you can apply some well-rotted organic fertilizer, or ordinary flower fertilizer.

Hydrangeas need to be kept in plenty of light at other times except for a little shade in summer. If there is not enough light for a long time, the branches and leaves grow thin and slender, the leaves become thinner, the night is not shiny, and the flowers are few, so they need to be exposed to the sun frequently.

1. What fertilizer is good for hydrangea occlusion?

Hydrangeas love fertilizer. If you want the plant to produce blue-purple flowers, you can apply some acidic fertilizer. When planting hydrangea, you can apply base fertilizer, which can be slow-release fertilizer, organic fertilizer, bone meal, cake fertilizer, etc.

This fertilizer can slowly provide nutrients to the plants, as long as the amount is well controlled, the fertilizer does not come into direct contact with the root system. In the growth period of the plant, you can top dress one limb ear with some liquid fertilizer, and you can use nutrient solution and various liquid fertilizers to top dress. This fertilizer can provide nutrients for hydrangea quickly, but it should be applied thinly and frequently to prevent hydrangea from becoming fertilized and burning its roots.

2. How to fertilize hydrangeas.

1.Base fertilizer: When planting hydrangea, it is generally necessary to mix base fertilizer into the soil.

Generally, for 20 caliber flower pots, mix 2g of slow-release fertilizer in the soil, or grab a handful of organic fertilizer. The smaller the pot, the less soil it holds, and the less fertilizer is used. 2.

Top dressing: During the growth period of hydrangea, fast-acting fertilizer can generally be poured into the soil. Diluted liquid manure is usually poured into the soil every half month.

Topdressing liquid fertilizer with balance of nitrogen, phosphorus and potassium during the growth period can promote growth, and phosphorus and potassium fertilizer can be applied before flowering to promote flowering. 3.Color:

Hydrangeas are pink in alkaline soils and blue in acidic soils. Therefore, flower lovers who want to color hydrangeas can use a blue toner to color hydrangeas when the hydrangea buds have just appeared, and generally spread a layer on the soil surface.

In the process of hydrangea growth, compound fertilizer or organic fertilizer can be applied to it, usually in the early stage of growth, nitrogen fertilizer is mainly used, and organic fertilizer can be used once a month. In the process of growth and development, you can apply cake fertilizer water every half a month or so. When the hydrangea is in the bud growth period, Xuhongsan can apply 2-3 times of diabsolute potassium hydrogen phosphate, which can promote the larger and more vivid opening of the flowers, and the fertilizer should be stopped during the flowering period.

When planting hydrangeas, it can generally be mixed with bottom fertilizer in the soil, and the bottom fertilizer can be slow-release fertilizer, organic fertilizer, bone meal, cake fertilizer, etc.

This type of fertilizer can provide nutrients to hydrangeas slowly, as long as you use the amount well and do not let the fertilizer come into direct contact with the roots.

In the hydrangea of the long-term search, and know that you can generally water the soil with fast-acting fertilizer, chase the fertilizer can use nutrient solution, various liquid fertilizers, etc.
