The suitable time for planting sweet corn is spring, the approximate time is about March to may, and the sowing time of each region should be changed according to the change of weather. Don't do it when it's too hot, it's not conducive to its emergence, and even if the seedlings grow out, they may be very thin. When it grows and matures, the yield will be very low.
1. Land: the land for planting sweet corn should have good fertility and higher softness, so before sowing, turn over the soil and add a proper amount of base fertilizer.
2. Variety: the selected seed shall have good lodging resistance. If it is planted in the north, the purchased seed shall have no cold resistance. Whether the seeds are of high quality will directly affect the yield, so if you want to have a higher yield when harvesting, you need to buy high quality healthy seeds.
3. Seedling thinning: the seedling thinning after sowing is also very important, because if the seedlings grow too thick, the seedlings will grow very thin and small, so remove the seedlings that are too dense in time.
