How many days after watermelon seedlings can they be transplanted?

Watermelon seedling cultivation is a highly technical job that requires careful care and management. After the seedlings are raised, when to transplant them is a key step. So how many days after the watermelon seedlings can they be transplanted? Let’s take a look below.

1. How many days after the watermelon seedlings can they be transplanted?

1. During the seedling stage, the key is to provide a suitable growth environment for watermelon, including appropriate temperature, light, water and fertilizer . Through careful care, the rapid growth of watermelon seedlings can be promoted and prepared for transplanting.

2. After the seedlings are raised, it will take about 25 days for the watermelon seedlings to grow to the four-leaf stage, which is the best time to transplant them. Transplanting too early may make it difficult for the seedlings to survive or slow their growth, while transplanting too late may cause severe root damage or even problems such as corking. Therefore, it is necessary to accurately judge the transplanting time based on the growth of the seedlings.

3. 5-7 days before transplanting, the watermelon seedlings need to be hardened at low temperatures. By extending the ventilation time during the day and lowering the temperature of the seedbed, we can promote plant rooting, enhance the frost resistance and disease resistance of the melon seedlings, and improve the survival rate after transplanting.

2. Watermelon planting methods and techniques

1. Soil selection and preparation

Choose fertile, well-drained soil for watermelon growing. Before planting, test the soil pH and make any necessary adjustments.

2. Seed selection and seed soaking

Choose high-quality, disease- and pest-resistant watermelon seeds for planting. The seeds can be soaked to improve germination rate and disease resistance.

3. Planting method and density

There are two common planting methods: direct seeding and seedling transplanting. The planting density is generally 6000-8000 plants/hectare.

4. Fertilization and water management

Apply organic fertilizer and mineral fertilizer reasonably according to soil nutrient conditions. Water regularly and keep the soil moist, but avoid standing water.

5. Pest and disease control

Inspect the fields regularly and take preventive measures in a timely manner, such as spraying pesticides and setting up pest control nets.

6. Bracket and pinching

A trellis system can be built to provide support for the watermelon vines. At the same time, appropriate pinching should be carried out to promote the development of side branches and ventilation and heat dissipation.

7. Disease prevention

Regularly carry out plant thinning, promptly remove diseased leaves and fruits caused by pests and diseases, sterilize wounds, and prevent the spread of diseases.

8. Harvesting and preservation

Choose the appropriate harvesting time according to the variety and growth cycle. After picking, be careful to avoid bruises, and maintain good ventilation and suitable temperature during storage.

That’s it
