What are the propagation methods for Polygala tenuifolia? A detailed explanation of the latest techniques
Polygala tenuifolia prefers a cool climate, tolerates drought, and dislikes high temperatures. It mostly grows wild in rather dry fields, roadsides, hillsides and other such places. It is best cultivated in sunny, well-drained sandy soil, followed by clay loam and calcareous loam. Clay soil and low-lying wet areas are not suitable for planting. Below, let us take a look together at the propagation methods for Polygala tenuifolia!
Seed collection of Polygala tenuifolia
Polygala tenuifolia is propagated by seed, either by direct sowing or by raising seedlings and transplanting. Because the capsules of Polygala tenuifolia split open when ripe and the seeds easily scatter on the ground, the seeds should be collected when the fruit ripens in July to August.
Direct sowing of Polygala tenuifolia in the field
Spring sowing is done in mid to late April, and autumn sowing in mid to late October or early November. On the prepared ground, scatter the seeds evenly into the furrows and cover with 1 to 2 cm of soil. For drilling, open shallow furrows at a row spacing of 20 to 23 cm, with a seeding rate of 11.25 to 15 kg per hectare. After sowing, press lightly and water thoroughly. Seedlings begin to emerge about half a month after sowing. For autumn sowing, seedlings emerge in the spring of the following year.
Raising seedlings and transplanting of Polygala tenuifolia
In early to mid March, drill on the seedbed, cover with 1 cm of soil after sowing, and keep the seedbed moist. The seedbed temperature should preferably be 15 to 20°C. Seedlings emerge about 10 days after sowing, and when the seedlings are about 6 cm tall they can be planted out. Planting out should be done on a rainy day or in the afternoon, at a row spacing of 22*5 cm.
