What are the propagation methods for Exochorda racemosa? Explained clearly in one article

1. Seed propagation.

The seeds of Exochorda racemosa ripen in August and September in autumn. After harvesting, they are sun-dried, threshed and stored in a sealed container. In February to March of the following year, they are sown in drills with a row spacing of about 20 cm. After sowing, a 1 cm thick layer of mud ash is spread on top, then covered with grass to retain moisture. Seedlings generally emerge after one month. In early April, once the seedlings emerge evenly, the grass cover can be removed. When the seedlings grow to 3-4 cm tall, thinning is carried out in stages; thinning is best done after rain or after watering on a sunny day.

During the seedling stage, attention should be paid to weeding, loosening the soil, and applying fertilizer two or three times. In hot summer weather, cover with grass to prevent drought. By the end of the year, the seedlings reach about 30 cm tall. They are transplanted in the following spring at the vernal equinox, and after two or three years of cultivation they can be used for landscaping or potted ornamental planting.

2. Cuttage.

Cuttage is best done in early spring when buds begin to sprout. For the cuttings, choose robust dormant branches from the previous year, cut them evenly at the node to about 12 cm long, treat them with rooting powder before inserting, then insert them into the cutting bed to a depth of a little less than half the length of the cutting. After inserting, water thoroughly, cover with a plastic film frame to retain moisture and provide shade, and keep the cutting bed moist.

3. Division.

Division is generally carried out in spring. Dig up the mother plant, keeping the roots intact, split it with a knife, and replant the divisions; they will survive.

Propagation methods of Exochorda racemosa

Cuttage of Exochorda racemosa

Hardwood cutting

Use dormant old branches of Exochorda racemosa for cuttage. This should be done in spring before buds sprout and leaves appear. Select robust old branches and cut them evenly at the node, with 2-3 internodes, and a cutting length of about 15 cm. Insert the cutting into the seedbed to two-thirds of its length. After inserting, water thoroughly, and roots will form in half a month.

Softwood cutting

For softwood cutting, usually choose vigorously growing plants in late spring or early autumn, and select current-year vigorously growing semi-lignified branches, keeping the front 2-3 internodes. Remove the leaves from the lowest internode, make a slanted cut of about 0.5 cm at the base, then insert the cutting into the seedbed, also to two-thirds of its length. Roots generally form in about 10 days.

Layering of Exochorda racemosa

Exochorda racemosa can be propagated by air layering, generally carried out in early spring and late autumn. The part of the branch buried in soil needs to be wounded to promote rooting. During layering, keep the soil moist, place it in an area with scattered light, and once it roots, separate it from the mother plant to form a new plant.

Sowing of Exochorda racemosa

Seed collection can be done in September, and sowing can be done in March of the following year. Choose well-aerated and fertile soil. After sowing, cover with plastic wrap to maintain humidity and temperature, and place in an area with scattered light. It will sprout and emerge in about 20 days. After emergence, the plastic wrap can be removed. When the seedlings grow to about 5 cm, thinning can be done to enhance their vigor and prevent sunscald. Before buds sprout and leaves appear the following year, they can be transplanted into new pots. Be sure to transplant with soil to prevent root damage.
