What are the control techniques for garlic bulb splitting?

1. Do a good job of drainage in the late stage of bulb expansion. Drain promptly after rainfall, do not apply heavy watering unless there is drought, and avoid excessive soil moisture.

2. Harvest in time. 18 to 20 days after harvesting the garlic scapes is the suitable period for harvesting garlic bulbs. When harvested early, the garlic skin is not only thin and white, but also less prone to splitting; when harvested late, if rainy weather occurs, the bulbs are prone to splitting. The standard for timely harvesting is when most of the plant leaves have dried up, the upper leaves have faded and then dried at the tips and drooped, the plant is in a soft state, and when pushed over to one side from the base, it shows a non-brittle and flexible texture as a sign of maturity, and it should be harvested promptly.

3. After harvest, dry the garlic promptly in the sun, cover the garlic bulbs with garlic leaves, and focus on sun-drying the garlic stalks and leaves to reduce the internal moisture content, so that the leaf sheath bases and protective bulb skins gradually lose water and dry out. During storage, protect against rain and moisture. In the early stage of storage, trimming off the fibrous roots of the garlic bulbs can delay splitting.
