What should be noted when transplanting grafted watermelon seedlings

(Agricultural Wealth Network) When transplanting grafted watermelon seedlings, note the following: First, select normally developed grafted seedlings for planting and discard poor seedlings. Second, grafted seedlings should not be planted too deep; the graft union must be 1 to 2 cm above the ground. If this phenomenon is found, the seedling's own roots should be cut off, and the surrounding soil should be pulled away from the hypocotyl to prevent the regrowth of its own roots. Third, because grafted watermelon seedlings grow vigorously, they should generally be planted sparsely. For early-maturing varieties, 600 to 800 plants per mu; for mid- and late-maturing varieties, 300 to 500 plants; train to three vines or multiple vines, and keep 1 to 2 fruits per plant.
