In early winter of the lunar calendar, fertilize and water and the temperature begins to rise. The first half of the month is 2 to 5 degrees, and the second half of the month is 7 to 10 degrees. The first half of the twelfth lunar month is 10 to 15 degrees, and the second half of the twelfth month is 15 to 20 degrees. Pay attention to pollination and thinning when flowering. Flowers, thin fruits, spray foliar fertilizer and potassium dihydrogen phosphate, control the temperature at 18 to 30 degrees, pay attention to weeding and moisturizing. It will be on the market in late March and early April. The price is best at this time. I wish you a good harvest and make a lot of money.
