When is it appropriate to top-dress watermelon

Let's talk about when it is appropriate to top-dress watermelon in terms of horticultural knowledge. Next, I will introduce you to this information.

When is it appropriate to top-dress watermelon

After watermelon enters the fruit expansion stage, it should be watered every 10 days and fertilized with a full water-soluble fertilizer, using 5-8 kilograms per mu. Top-dressing during the seedling stage of watermelon is mainly to promote the development of the plant's root system and should apply a small amount of fast-acting nitrogen fertilizer. In the period of 4-5 true leaves, urea needs to be applied, and the soil should be covered immediately after application. Before the vines start to stretch after transplanting, applying human waste urine each time, combined with tillage to loosen the soil, will yield better results.

Watermelon seedling stage top-dressing

The first top-dressing of watermelon seedlings, known as seedling promotion fertilizer, is when the cotyledons form a cross shape, applying urea. For fields with higher fertility or sufficient base fertilizer, top-dressing may not be necessary during the seedling stage to prevent excessive growth, which is not conducive to fruit setting.

Watermelon growth stage top-dressing

After the watermelon fruit is stable, apply fruit expansion fertilizer, choosing fast-acting water-soluble fertilizer to promote rapid and vigorous growth.

When the young seedlings have grown 4-5 leaves, apply fast-acting fertilizer to promote faster growth of the seedlings. When the seedlings start to stretch and climb, apply a vine promotion fertilizer with potassium, calcium, and urea to accelerate leaf growth and lay the foundation for flowering and fruiting.

High-yield top-dressing methods for watermelon

Top-dressing during the watermelon seedling stage is mainly to promote the development of the plant's root system and should apply a small amount of fast-acting nitrogen fertilizer. In the period of 4-5 true leaves, urea needs to be applied, and the soil should be covered immediately after application. After transplanting and before the vines start to stretch, applying human waste urine each time, combined with tillage to loosen the soil, will yield better results.
