The best time to plant watermelons outdoors

Open-air watermelons are suitable for planting in spring, approximately in March and April each year, because the temperature and humidity at this time are more suitable, and open-air watermelons have a higher demand for water during the growth process. In order to promote the growth of open-air watermelons, open-air watermelons can also be planted after the spring rain.

How to plant watermelon outdoors

1. Germination treatment: When planting open-air watermelons, you need to select seeds with full grains and no damage. In order to eliminate the bacteria on the surface of the open-air watermelon seeds and reduce the infection rate of open-air watermelons, the seeds should be soaked in carbendazim for 15-20 minutes.

2. Planting method: Open-air watermelon is suitable for growing in loose and breathable sandy soil. When planting open-air watermelon, you need to evenly spread the seeds on the surface of the soil, and then cover it with a layer of plastic film to keep the temperature in the soil constant. After the open-air watermelon seedlings emerge, use a knife to cut the plastic film nearby to promote its healthy growth.
