There's More to Saving Garlic Seed Than You Think: A Full Breakdown of the Latest Tips

Garlic is a common seasoning in our daily lives. It reproduces asexually, and the garlic clove is a modified lateral bud. Long-term asexual reproduction inevitably causes viruses to accumulate continuously within the plant, leading to seed stock degeneration. So how should we overcome this problem of saving garlic seed? Let's take a look together.

1. Establish off-site seed-saving fields

Establish garlic seed fields with a certain degree of regional difference and cultivation difference. This can prevent garlic degeneration, improve garlic seed quality, and provide a certain off-site growth advantage. For example, exchange between mountainous areas and plains, exchange between dryland areas and paddy fields, exchange between vegetable gardens and grain fields, and off-site exchange in different directions within a certain range, such as between the south and the north. This can improve garlic yield and seed quality to varying degrees.

2. Select pest- and disease-free garlic bulbs as seed

When harvesting garlic for the seed field to save seed, plants with the morphological characteristics of that variety should be selected as the standard, requiring seed garlic with disease-free leaves, plump bulbs, uniform color, a moderate number of cloves, and no pests or diseases. After selecting good seed garlic, tie it into small bundles and harvest and store them separately. Note here that the garlic bulbs should be thoroughly dried and stored in a cool, ventilated environment; otherwise, a high-temperature, high-humidity environment will reduce the vitality of the garlic buds and may even cause the seed to rot.

3. Use aerial bulbils as seed

In order to improve the seed quality and vitality of garlic, garlic aerial bulbils can be used as seed. The method is: after the garlic bolts, do not harvest the garlic scapes, and delay the bulb harvest period by 15-20 days. When the garlic scapes turn yellow and the aerial bulbils are mature, harvest them, and select those with a diameter greater than 0.4 cm to store through the summer. In autumn, open furrows on the raised beds for drilling in rows or broadcast sowing, generally controlling it at about 120,000-150,000 plants per mu, then cover with about 2 cm of soil, press down, and water. Subsequent management is the same as sowing cloves. Aerial bulbils generally grow into single-clove garlic in the first year. Although this method can improve seed quality and prevent garlic seed degeneration, it is not suitable for some varieties. For example, garlic without scapes, or with thin and small scapes that do not form bulbils, cannot be propagated by this method.

4. Garlic with secondary growth cannot be kept for seed

Fields where garlic shows secondary growth due to cultivation, climate, and other conditions cannot be used for seed saving. Secondary growth in garlic is itself a phenomenon of seed degeneration, seriously affecting garlic yield and quality. If such plants are selected for seed saving for another season, it will cause even more secondary growth and severe yield reduction, so they cannot be kept for seed.
