The time is shorter in warm areas, longer in cold areas, and shorter in the Yangtze River basin. The time in the north is longer, but the time of some early-maturing varieties is shorter than that of late-maturing varieties, and the time in the greenhouse is shorter than that in the open field.

1. Maturity time

Generally speaking, if watermelons are planted in the open field in March, they will mature in June. It takes about 90 days for early-maturing varieties, such as Zaochunyu; about 100 days for middle-maturing varieties, Xinong R; and 120 days for late-maturing varieties, such as Hongyou 2. It probably matures in June to July. Greenhouse planting, choose early-maturing varieties, probably planted in February, can be on the market at the end of April and May.

2. Growth period

The whole growth period mainly has four periods, germination stage, is the cotyledon expansion period, mainly depends on seed nutrients and cotyledon photosynthesis to provide nutrition, mainly the growth of root system. It needs a temperature of more than 25 degrees. At the seedling stage, the true leaves grow to six true leaves, mainly for the growth of leaves and stems. It needs a temperature of more than 20 degrees. During the vine-drawing period, it is mainly for rapid plant growth and female flowers. It mainly turns to reproductive growth, which requires a temperature of more than 20 degrees. Fruiting period, flowering to maturity, mainly flowering and fruiting, nutritional supply, between 20 and 26 degrees.

4. Mature period

The south is precocious, d matures in June, the north matures in July, protected cultivation, the four seasons can be cultivated, the mature time should be determined according to the planting time, early spring mature in May, autumn planting, winter can also mature. Land planting matures from June to September, depending on the variety. Sometimes it depends on the climate and altitude, the mature period of high altitude will be later, the climate will be dry and warm earlier.

The maturity of watermelon after planting mainly depends on the variety, planting site, climate, altitude, environment, temperature and other influencing factors, as well as the maturity of watermelon itself. But it's usually three to four months. I hope the above information will be helpful to all of you.
