The division propagation method of Alpinia glabra

Preliminary preparations for propagation of Alpinia serrulata

Soil selection

When propagating Alpinia officinalis, you should choose fertile, neutral to slightly acidic sandy soil.

The soil should have good aeration and drainage, and must not be too sticky or dense. The cultivation soil can be made by mixing equal amounts of loam, peat soil, and leaf mold, with some river sand and charcoal powder added.

temperature

Around the spring equinox, the plant of Alpinia galanga begins to sprout new buds in large numbers. Spring and summer are the best times for Alpinia galanga to be propagated by division.

The propagation of Alpinia glabra by division

In spring and summer, dig out the underground rhizomes of Alpinia officinalis, shake off excess soil, separate the tangled roots as much as possible, and use a sharp knife to split it into two or more plants. Each separated plant must have a considerable root system.

Then trim the leaves appropriately and cut off the above-ground stems and leaves to facilitate survival.

The rhizome selected for division can be 4 or 5 cm long. Just pot it directly.

Late-stage maintenance of Alpinia serrulata propagation

Fertilization

After the plant germinates after transplanting and before leaves grow, you can apply an appropriate amount of liquid fertilizer mainly composed of nitrogen fertilizer to promote the growth of Alpinia serrulata leaves.

Around the beginning of summer, apply phosphorus and potassium fertilizers to promote bud formation and flowering.

Watering

After dividing and potting the Alpinia serrulata, the roots should be irrigated or watered thoroughly. In the next 3-4 weeks, water sparingly and less frequently to avoid root rot.

At the same time, spray the leaves 1-3 times a day to ensure moisture on the leaves.
