Top dressing is an important element of care when growing zucchini. Here are the best dressings that will increase the yield of zucchini. With them you will have great tasting fruits. After all, nutrients should be introduced in stages, observing the dosages.
What nutrients do zucchini need in July
Soil composition is important for the crop throughout the growing season. Zucchini grow quickly, they are demanding in nutrition. With favorable weather and timely planting, the first buds appear in late June, and mass flowering and fruit formation begins in early July. Fertilizers should be used very carefully and balanced during this period.
- without a sufficient amount of boron, the outer skin of zucchini will be covered with lines and streaks;
- lack of iodine will lead to rotting of the crop;
- potassium deficiency contributes to the formation of a spherical tip in zucchini; a lack of calcium will cause the central part of the fruit to shrink;
- a shrunken bright tip indicates nitrogen deficiency. Phosphorus improves taste and boosts immunity.
What is the best fertilizer to use
In July, the plant gives full strength to fruit set and growth, the nutrient requirements increase significantly. The cultivation of zucchini needs above all potassium and phosphorus. Nitrogen during this period requires a minimum amount. To feed zucchini, a combination of mineral fertilizers with folk remedies is used.
In early July, zucchini can be fertilized with green infusion or nitrophoska. During active fruit formation, the need for phosphorus and potassium supplements increases, which not only strengthens plants, but also helps reduce the number of empty flowers. It is better to use superphosphate and boron.
How to prepare a composition for fertilizing zucchini in July
Green infusion is prepared at least a week before the meal: 1/2 bucket of chopped grass without seeds is poured with water, covered with a lid and left to ferment for 7 days.
The resulting concentrate is diluted with water, at the rate of 1:10, 1 glass of sifted wood ash is added, and mixed.
To prepare a nutritional composition based on nitrophoska for zucchini in July, 30 g of granules should be dissolved in 10 liters of water. An aqueous solution based on boron and superphosphate is prepared according to the scheme: 1 g of acid + 30 g of superphosphate are diluted in a small amount of hot water and the volume is adjusted to 10 liters.
Rules for fertilizing zucchini in July
When fertilizing zucchini, it is important to remember the moderation of fertilizing, deficiency and excess of nutrients are harmful to plants, so the dosage should be maintained.
The infusion is watered under the plants, in pre-moistened soil, in the morning or in the evening, at the rate of 1-2 liters per bush.
A solution of nitrophoska is applied with irrigation, avoiding touching the stems and leaves, spending 1 liter of the nutrient composition for each bush.
Zucchini is watered with a nutrient composition of boron and superphosphate after evening or morning moistening, with a consumption rate of 3 liters per plant.

What to do if zucchini are loosely tied
There are several reasons why there are no or very few ovaries on zucchini. One of the most likely is that the female flowers are not pollinated due to the absence of bees. In such a situation, it is necessary to spray the flowers with sugar syrup: dissolve 0.5 sand in 1 liter of water at room temperature and add oil (clover, sainfoin, phacelia, bruise, linden). Another common cause is nutrient deficiencies, even with regular fertilization.
To activate the growth of the crop, flowering and fruit set, Bud is used as a foliar dressing, in the ratio of 20 g of the drug per 10 liters of water. A good stimulating effect is given by the introduction of urea during flowering and fruit pouring: 10 g of the drug is dissolved in a bucket of water and applied under the root with watering 1 time 10-12 days until improvement.
