What causes secondary growth in garlic? Teach you effective prevention methods
Garlic is an essential vegetable in our daily lives. As demand for it grows, its planting area is gradually expanding. However, improper planting and management methods have led to secondary growth in garlic. Secondary growth causes deformed garlic and disordered arrangement of cloves, seriously affecting quality and yield. So what causes secondary growth in garlic? How can it be prevented? Let's take a look together.

I. Causes of secondary growth
1. Improper selection of garlic varieties for planting. The genetic characteristics of seed garlic are the main factor in secondary growth. When selecting seed garlic, the local growing environment must first be considered, and a garlic variety suitable for local growing conditions should be chosen. When selecting seed garlic, it should have large bulbs, plump cloves and obvious separation. If a variety not suitable for local growing conditions is chosen, secondary growth is very likely to occur.
2. Improper storage of garlic seed. One month before sowing, if the seed garlic is stored at a temperature below 16 degrees and an air humidity above 75%, the low-temperature and high-humidity environment will increase the secondary growth rate of the seed garlic.
3. Improper treatment of garlic seed. In many regions, farmers treat the seeds before planting garlic. If low-temperature seed treatment is used, the garlic will sprout earlier after sowing, and secondary growth is very likely to occur.
4. Improper sowing time. Garlic has strict requirements for temperature, light and nutrients. If the sowing time is improper, it will affect the growth of the bulbs and cause secondary growth.
5. Improper selection of cloves. Some people believe that when selecting seed garlic for sowing, the larger the clove, the better, as it is beneficial for the seed garlic, but this is incorrect. The size of the seed garlic cloves must be within a certain range. If too small, single-clove garlic is easily formed; if too large, secondary growth is easily caused.
6. Cultivation and management measures. Although garlic has strong adaptability, it is relatively sensitive to the growing environment, nutrients and water. During management, if nitrogen fertilizer is applied excessively or too much fertilizer and water are used, secondary growth will be caused.
II. Prevention methods
When selecting varieties, be sure to consider the local environment and choose varieties suitable for local planting. When storing seed garlic, be sure to choose an environment with a temperature above 20 degrees and air humidity below 75%. When treating seed garlic, low-temperature treatment methods should not be used. Choose cloves of appropriate size, neither too large nor too small. The sowing time must be well controlled, and neither early nor late sowing is suitable. In addition, reasonable close planting should be carried out.
