What is the best fertilizer for grapevines
When planting grapevines, a base fertilizer can be applied to the soil, mainly organic fertilizers, such as decomposed manure or compost per mu. During the growing period, human waste or compound fertilizers containing nitrogen, phosphorus, and potassium or urea can be applied to promote flowering and fruiting. Phosphorus and potassium fertilizers are mainly applied when the fruit is coloring. After the fruit is harvested, to restore the tree's vitality and promote branch growth, phosphorus and potassium fertilizers need to be applied.
Grapevine fertilizing time
Grapevines can be fertilized with germination fertilizer, weak branch supplements, young fruit expansion fertilizer (fruit strengthening fertilizer), sugar-increasing coloring fertilizer, and foliar fertilizer.
Grapevines are top-dressed 3-4 times a year, mainly with fast-acting fertilizers. The first top-dressing is done before germination, mainly with nitrogen fertilizers. The second top-dressing can be done after the fruit is set, with human waste or compound fertilizers containing nitrogen, phosphorus, potassium or urea. The third fertilization needs to be done when the fruit is coloring, mainly applying phosphorus and potassium fertilizers.
The fourth top-dressing is after the fruit is harvested, to restore the tree's vitality and promote branch growth, phosphorus and potassium fertilizers need to be applied.
What type of fertilizer for grapevines
1. Grapevines need to be fertilized with nitrogen, which has a significant effect on their growth and development, can promote the development of lateral branches, increase the number of leaves, and can promote flowering and fruiting.
2. Grapevines need to be fertilized with phosphorus and potassium fertilizers, which can restore tree vigor, promote bud differentiation, and also improve their cold resistance and fruit quality.
3. Grapevines need to be fertilized with boron and zinc fertilizers, which help to improve their fruit-setting rate, improve the nutritional status of grapes, and increase yield.
Grapevine fertilizing methods
1. Apply base fertilizer: When planting grapevines, a base fertilizer can be applied to the soil, mainly organic fertilizers, such as decomposed manure or compost per mu.
2. Top-dressing: Grapevines are mainly top-dressed during the growing period to promote bud differentiation, promote plant growth and fruit development, and increase the fruit-setting rate.
3. Bud-promoting fertilizer: Applied before the spring starts to germinate, mainly with fast-acting nitrogen fertilizers, after top-dressing is completed, immediate watering is necessary to promote uniform germination.
4. Flowering fertilizer: Apply a compound fertilizer containing nitrogen, phosphorus, and potassium one week before the grapevines flower to promote bud differentiation and extend the flowering period.
5. Fruit expansion fertilizer: After the grapevines flower, a combination of fast-acting nitrogen fertilizer and compound fertilizer can be applied to increase the fruit-setting rate and improve yield.
6. Color and sugar-increasing fertilizer: Apply phosphorus and potassium fertilizers before or at the beginning of fruit coloring.
Notes on grapevine fertilizing
The base fertilizer must be fully decomposed before application to avoid burning the roots. After fertilizing, it is necessary to water in time to avoid fertilizer damage. Fertilize in moderation; the amount should not be excessive, and raw or concentrated fertilizers should not be used. Fertilizing every year should not be done in the same place to avoid affecting root growth.
