After it is planted, it should be leveled with a wooden board and watered. After the water has penetrated, 5-6 cm of fine sand is placed on the surface to facilitate moisturizing and harvesting. When the seedlings grow to 12 to 15 centimeters long, pour the water; pour the water 3 to 4 days before the harvest.
After controlling the temperature, garlic should be kept at 22-24°C for 4-8 days. 5 to 6 days before harvest, 18 to 20°C should be maintained. The night temperature during the entire growth period is not lower than 16 to 18°C, the bed temperature should be maintained at 18 to 20°C, and the room temperature should be maintained at 25 to 28°C. It should be noted that when the temperature up to 28 ~ 30 °C or less than 15 ~ 16 °C, garlic sprouts appear jaundice tips.
