When is the planting time of watermelon in South China?

The best season to grow watermelons in South China is to raise seedlings during the Spring Festival and sow in February and March. As long as the temperature can be between 18-35, it can be planted continuously.

It is best to grow watermelons with farmyard manure (spring and autumn). There are many kinds of farmyard manure, including miscellaneous manure, dry manure, human excrement, plant ash, chicken manure, pig manure, rapeseed cake and so on. Soil miscellaneous fertilizer is the most accessible and widely used organic fertilizer in rural areas. Generally, it should be sown in the high-yield ditch 15~20 days before sowing or planting, or it can be scattered on the ground before turning the ground, so that it can turn underground when turning deeply. Manure is a mixture of a small amount of soil in the sun, which can be used as the base fertilizer or topdressing of watermelon. Human excrement is a kind of organic fertilizer, which is mainly used as topdressing after fermentation. Plant ash can be used as a potash fertilizer with the best topdressing effect. Chicken manure and rapeseed cake are organic fertilizers with high phosphorus and potassium content. After full fermentation, it is used as base fertilizer, which has many nutrients and long fertilizer effect, and is a good fertilizer for cultivating watermelon.
