In fact, the recommended practice is to irrigate one metre deep. It is imperative to irrigate the soil deeply before transplanting the watermelon seedlings. Adjust the fertilisation programme according to the plants’ development requirements.įarmers can plant anything from 4000 plants per hectare to as many as 8000 plants and this depends on the cultivars, the area of growth, and the soil conditions. Irrigate the plants directly after planting them. ![]() Firm the soil around the plug to prevent air pockets from forming around the plant’s root zone. Holes must be prepared in advance and the seedlings should not be planted too shallow or too deep. The watermelon seedlings’ root zone must be wet during the planting process. Make sure all the preparation has been done by the time delivery day comes. The field must be cleared of weeds and if plastic covering is used, make sure that it is tight at the ridge to prevent the plastic from touching the seedlings’ stems. It is thus imperative to ensure an optimal soil structure at up to 40 cm deep. Watermelon plants have roots reaching as deep as 40 cm into the soil. With deep soil preparation, it is possible to reduce the prevalence of soil-borne disease problems. It is essential to prepare the soil to a deep level, as watermelons have extensive root systems. Soil Preparation Before Transplanting Watermelon Seedlings Seedless varieties are now also available. The sizes of the fruit range from small to extra-large and this depends on the cultivars. Watermelons come in many varieties, ranging from elongated to cylindrical fruits. If the soil’s pH is 5,4 or lower, it is recommended to add lime. The soil’s optimal pH range for growth is between 5,7 and 6,3. Sandy loam is suitable, provided that good drainage is possible. It is best to avoid heavy clay or shallow soil. The plant is quite adaptable to different soil types, but it grows best in sandy soil. During the ripening stage, the optimal temperature range changes to between 14 and 26 ☌. ![]() Its best temperature range for optimal growth is between 17 and 21 ☌ at night and between 23 and 31 ☌ during the day. It produces male and female flowers, with the female flowers staying open for around 24 hours. The plant is widely cultivated in South Africa and many other countries around the world.
