How to prune葡萄树 after flowering
After葡萄树 flowers, there is no need to prune the branches, just remove the side shoots and残花, arrange the light properly, and apply phosphorus and potassium fertilizers. After the new buds of葡萄tree sprout, pruning is required to prevent blossom and fruit drop. It's important to pay attention to any withered or diseased branches and deal with them promptly.
Pruning葡萄tree after flowering
1. Pinching: There are many varieties of葡萄, for those with a higher fruit-setting probability, pinching can be done 3 days after flowering, with the removed tendrils usually about 10 cm long.
2. Thinning inflorescences: To properly handle the inflorescences, remove excessive ones and also those that are not developing well. This can reduce nutrient consumption and ensure that the remaining inflorescences receive enough nutrition, which can also improve the quality of the grape clusters. Generally, each fruiting branch is left with one inflorescence, and the rest can be removed.
3. Thinning fruit: About a week after葡萄 flowers fall, when the grapes have grown to the size of mung beans, thinning can be carried out, removing some weaker grapes to balance the number of clusters.
Pruning葡萄tree during flowering
Pruning during flowering: After葡萄tree sprouts new buds, pruning is required. One week before flowering, to prevent blossom and fruit drop, pinching of new shoots is necessary. It's important to pay attention to any withered or diseased branches and deal with them promptly.
Reasons for not flowering:葡萄tree may have consumed a lot of nutrients due to high yield the previous year, affecting the differentiation of flower buds; or there may be too many branches on the葡萄tree, using a large amount of ethylene-based colorants, leading to a lack of nutrition for the flower buds, resulting in no flowering.
Methods to promote more flowering: When the winter buds sprout in spring, pinch the top ten leaves on the new shoot to inhibit the growth of the main shoot, while retaining the top two summer bud side shoots.
Care methods for葡萄tree after flowering
1. Appropriate top dressing: During the flowering period of葡萄, pay attention to top dressing. Apply decomposed organic fertilizer to葡萄 and spray boric acid or borax water before flowering to supplement nutrition and improve the fruit-setting rate of葡萄.
2. Maintain temperature: Pay attention to controlling temperature and humidity, keeping it around 28℃ during the day and 16-18℃ at night.
3. Control watering: After flowering, control watering to avoid excessive water causing fruit drop.
4. Pest and disease control: Take measures to prevent and control pests and diseases.
