Can coleus be propagated by cuttings in summer?
Coleus can be propagated by cuttings in summer, and this is also its best season for cuttings. First, you need to select a branch with three to five nodes and some terminal buds on the stem, about ten centimeters long. Next, trim the leaves on the stem to reduce nutrient consumption; generally, all the lower leaves of the branch should be cut off. Finally, insert the branch into moist sandy soil and keep it in a cool, ventilated place.
Propagation methods for coleus:
1. Cutting time for coleus: Coleus propagation methods include sowing and cuttings, among which cutting propagation is the simplest. It can be done throughout the year, except in winter when low temperatures slow rooting; spring and summer have suitable temperatures and are the best seasons for cuttings.
2. Coleus branches: Coleus is a perennial herbaceous plant, but in homes it is mostly grown as an annual. It is very suitable for propagation by terminal bud cuttings. Select a stem node with terminal buds and 3 to 5 nodes, 5 to 10 cm long, as the cutting. After cutting the cutting, trim some of the leaves to avoid excessive leaves causing water loss from the branch and cutting failure. Usually, all the lower leaves of the branch should be cut off, and keeping just a few upper leaves is enough.
3. Cutting method for coleus: Coleus grows quickly, so a healthy branch can be directly inserted as a single cutting into a flower pot with a diameter of 7.5 cm. After successful rooting, it can be grown directly in the pot. If there is more space at home and the environment is suitable, it can be inserted into a larger planter.
4. Rooting time for coleus: Coleus roots very quickly. About one week after cutting, roots can grow. Two weeks after cutting, apply diluted liquid fertilizer or slow-release fertilizer so that the coleus enters the initial growth stage. After the coleus grows normally, pinch it back once to promote branching and improve the ornamental value of the small potted plant.
The small cuttings gradually grow larger. They can be planted in flower pots or grown in large pots as potted combinations. In addition, coleus grows quickly in summer, so proper pruning is needed to keep it attractive.
