Question 1: How to fertilize potted grapes. The management of potted grapes is more complicated than field cultivation. Water, water once a day in summer, and once again when wilting at noon. The amount of water should be just enough to thoroughly water; fertilize, apply thinly and frequently. Fertilizer types: urea and potassium dihydrogen phosphate, diluted 300 times. For root irrigation, you can take out a part of the leaves and spray them; for pruning and trellising, different tree shapes should be used according to the size of the balcony space. If the space is large, you can use a trellis, and if the space is small, you can use a hedge. In summer, you should often top off to prevent Leggy, pruning in winter should be done appropriately according to different rack styles, leaving 8-10 sections for extension heads and 4-5 sections for general new shoots.

Question 2: How to fertilize potted grapes? What kind of fertilizer should be used? It is better to use all-element compound fertilizer. It is better to spray potassium dihydrogen phosphate on the leaves frequently, which can promote the flowering and fruiting of plants. Grapes like light and can be placed brightly on the balcony. A well-ventilated place is better. Just water it when it is dry. If the soil is not dry, water it if it is dry. You are afraid of waterlogging.

Question 3: When should I fertilize potted grapes? Fertilization time:

1) At the beginning of germination, nitrogen-based fertilizer should be applied once or twice to promote lush growth of branches and leaves and facilitate flowering;

2) Before flowering Apply 1 to 2 times of thin fertilizer mainly composed of phosphorus and potassium;

3) When the flowers fade and the fruits are set, in order to make the fruits expand, apply dry cake water every 7 to 10 days. The odor evaporates, and the dry cake water is applied in ditches. First dig a 2cm to 3cm trench around the edge of the pot, apply dry cake fertilizer and water into the trench, cover the soil immediately, and gradually increase the fertilizer from light to thick. You can also scatter the decomposed dry cake powder on the surface of the pot soil, let it mature again in the pot, and mix it with the soil evenly after 7 to 10 days.

Fertilization precautions:

The principle of fertilizing potted grapes is to apply it sparingly and frequently.

1. For potted seedlings that have not yet produced fruit, generally start with a seedling height of about 20cm (i.e. 6-7 leaves). Apply cake fertilizer and water once every 7-10 days until the end of September.

2. For potted grapes that have produced fruit, it is best to apply once every 5 days to ensure fruit development. After the fruits are harvested, they are applied to potted seedlings. Pay attention to watering immediately after each application of liquid fertilizer.

3. Foliar spraying of fertilizer can also be carried out.

(1) In the early growth stage of potted grapes, spray 0.1-0.3 urea solution 2-3 times;

(2) Starting from the fruit expansion stage, spray every 7-10 Spray 0.3 potassium dihydrogen phosphate solution 3-4 times on Tianke.

Question 4: Potted grapes. I don’t know how to fertilize grapes. Before flowering, you need to promote the growth of the root system. You can use Fujinmen’s special water-soluble fertilizer to promote rooting. During the flowering and fruit setting period, you need to increase the flowering and fruit setting rate to preserve flowers and preserve the fruit. If the fruit effect is good, use high-nitrogen and high-potassium water-soluble fertilizer. During the fruit expansion period, use special water-soluble fertilizer for fruit expansion to promote the growth of the root system and improve the quality and yield of grapes.

Question 5: Do potted grapevines need to be fertilized? Go to the flower shop to buy compound fertilizer and bury 20 grains on the edge of the pot. Don't use too much, as it will cause fertilizer damage.

Question 6: Fertilizing potted grapevines. What I bought is how to use compound fertilizer and how much to apply at one time. How to fertilize flowers. Fertilizing flowers must be timely and appropriate, and the season and time must be mastered. Generally speaking, fertilization is applied during the growing season of flowers. Flowers with strong growth need more fertilizers; all-vegetarian fertilizers are applied in the seedling stage, phosphate fertilizers are mainly used in the flowering and fruiting stages, and nitrogen fertilizers are mainly used for foliage flowers. Stop fertilizing flowers in the dormant period. In addition, we must also master the principle of "fertilize thinly and apply frequently", that is, "eat less and eat more." During the growth period of flower seedlings, it is best to apply thin fertilizer and water once every 10 days. Fertilizing in the evening is best. Avoid fertilizing around noon because high soil temperature can easily damage the roots. Organic fertilizer must be fully decomposed before application. The controlled-release fertilizers developed in recent years can be effective for half a year or even longer. The amount of one-time application can be larger than that of water-soluble fertilizers. The gradual release of nutrients can meet the nutrient needs of flowers for a long time. There are two methods of fertilizing flowers, namely base fertilizer and top dressing.

Base fertilizer refers to the fertilizer that is applied to the soil before planting flower seedlings. When planting flowers in the open field, mix the base fertilizer into the soil first, and then cover the soil with soil to plant the seedlings. For indoor potted flowers, base fertilizer can be put into the bottom layer of the pot soil, such as bean cakes, fish bone meal, etc. . Be careful that the roots do not come into direct contact with the fertilizer. Some flower production companies have begun to use controlled-release fertilizers as base fertilizers. Top dressing refers to the fertilizer applied during the growing season of flower seedlings. For flowers in the open field, dry fertilizer can be applied around the seedlings and then watered, or water and fertilizer can be poured directly. For potted flowers, you can sprinkle dry fertilizer on the surface of the pot soil, then loosen the soil and water it. For top dressing, use soybean cake, sesame paste residue or soaking liquid such as water chestnut slices and sheep horns. After fermentation, it will be made into fertilizer water for application. Fertilizer and water are suitable for large potted flowers placed in flower beds or in the open air. Flowers with strong acidic soil in the south, such as camellia, rhododendron, gardenia, smile, Milan, jasmine, etc., can be irrigated with water by adding 0.1% ferrous sulfate to the soaked fertilizer water. It can also be mixed and extruded with various chemical fertilizers to form solid fertilizer tablets for top dressing. Or use a fertilizer solution with a concentration of 0.1 (1 tael of fertilizer plus 100 pounds of water) to spray on the above-ground part of the flower seedlings and spray it on the leaves, which can make the leaves of the flower seedlings dark green and shiny, and also prevent flowers and fruits from falling.

Question 7: Is it difficult to cultivate potted grapes? What kind of fertilizer is good? Potted grapes require larger pots, but there is no need to bury animal carcasses in the soil. It is best to use other organic fertilizers instead. When animal carcasses rot and ferment, the smell is too unpleasant and the pollution is extremely serious.

For organic fertilizers, it is generally appropriate to choose chicken manure, pig manure, cow manure, etc. If these fertilizers are not available, you can choose sesame paste residue (sesame oil residue) or bean cake instead, and the effect is equally good. .

If there are many rotting leaves in the pot soil, you can mix it directly with river sand, and then topdress the grapes during their growth.

Question 8: What kind of fertilizer should be used for potted grapes? Pu'er fertilizer

Question 9: Is it necessary to fertilize potted grapes? If so, what kind of fertilizer should be used? Which kind is better and how to apply it? Grapes like fertilizer, but if it is not fertilized, it will be difficult to bear fruit. Even if they bear some fruit, they will easily fall off. Apply thin liquid fertilizer every 10 days during the growth period. When the stems and leaves are growing, nitrogen fertilizer will be the main fertilizer. Before flowering and after fruit setting, phosphorus and potassium fertilizer will be the main fertilizer. .

Question 10: Can anyone tell me what fertilizer to use for potted grapes? When the grapes are placed in the pots before the Qingming Festival, some old roots can be trimmed, new culture soil added, and base fertilizer applied. The base fertilizer can be bean cakes, egg shells, crab shells, bone meal, etc. Apply top dressing once every 10 days after the new shoots sprout. Use bean cakes, fish heads, fish intestines and other retting buds to grow. Use liquid fertilizer after each preparation is decomposed. Do not fertilize too thickly and be sure to water after application. The principle of fertilization is to "apply thin fertilizer frequently". In May, when the flowers and leaves are in full bloom, apply more nitrogen fertilizers. After June, mainly apply nitrogen and phosphorus mixed fertilizers. After July, apply nitrogen, phosphorus, and potassium fertilizers. After September, you can apply potassium fertilizers.
