What should I do if the bud withers before it opens?

The treatment methods of bud withering before opening are: watering, applying phosphorus and potassium fertilizer and shading.

1, permeable

Generally speaking, buds do not bloom and wither because the soil is short of water, buds do not have enough water, and wither and do not bloom. It is necessary to water plants and keep the soil moist during flowering.

2. Apply phosphorus and potassium fertilizer

Flowering is a very nutrient-consuming process, which requires timely fertilization. Without nutrition, the buds will wither. Generally, nitrogen fertilizer is not used for flowering fertilizer, but phosphorus and potassium fertilizer are used much, and nitrogen fertilizer is easy to grow in vain. In the first half of flowering period, potassium dihydrogen phosphate crystals were added with water 1000 times.

3. Shading treatment

Excessive light is also one of the main causes of bud withering, so it is necessary to shade the plants at noon, or directly place the plants in bright and scattered places when flowering. Too strong sunlight will make the bud temperature too high, lose water too fast, wither and wither, and not bloom.

Methods of promoting flower bud opening

1, spray to grow three sauce Su Yang.

You can choose to buy a suitable bottle of rose growth hormone and dilute it with water. Spray the diluted auxin on the flower bud, so that the whole flower bud will be infected with auxin, and wait until the flower bud absorbs nutrition for one day before flowering.

Step 2 spray sugar water

Supplementing sugar to the bud in time can also make it have enough nutrition to bloom and prepare the right amount of glucose. You can also choose white sugar or other sugar substances, dilute them with water so that the sugar is not too high, and then spray them on the flower buds to promote the flower buds to bloom.

Step 3 blow open the bud

The common way to make buds bloom is to blow them away directly with the wind. You can directly soak the roots of flower buds with hot water, and blow them on the flower buds with a hair dryer after 24 hours. Be careful not to blow too much air. It is best to cover the blower with a layer of gauze to let the buds bloom as soon as possible.
