When is the best time to propagate osmanthus trees
Propagating osmanthus trees in the summer and autumn is better, with the specific time being May to July and September to October. During these two periods, the new shoots stop growing, nutrients are more abundant, and the climate and temperature are more suitable, making it easier for roots to form and survive. After propagating osmanthus trees, do not water too much, keeping the soil slightly moist is sufficient. Too much watering will affect the growth of new roots.
Osmanthus Tree Propagation Season and Months
Propagating osmanthus trees in the summer or autumn is more suitable, with the specific time being May to July and September to October. During these periods, the new shoots stop growing, nutrients are more abundant, and the climate and temperature are more suitable, making post-planting management easier and roots more likely to form and survive.
Osmanthus Tree Propagation Methods and Steps
1. Prepare the soil
Use fine, well-ventilated soil as the propagation bed, and set up a arch棚 50 cm high above the bed surface, covered with a shade with a light transmission rate of 30%.
2. Cut branches
From healthy, pest-free plants, cut a branch about 8-10 cm long, preferably using this year's new tender branches. Wrap the base with a wet tissue after cutting.
3. Treat the branches
Then remove the leaves, leaving only 2-3 at the top, cutting the leaves in half, and cutting the base into a slanting shape. Tie them into a small bundle and soak in water with rooting powder for 1 hour to help the roots adapt to the new environment more quickly.
4. Propagate
Make a hole in the prepared propagation bed, place the treated cutting into it, cover it with fine soil, and water it.
Post-Propagation Care for Osmanthus Trees
1. Watering
Keep the potting soil of the propagated osmanthus trees slightly moist, as too much watering will affect the growth of new roots and may even cause root rot. You can also spray water mist on the leaves to maintain humidity.
2. Fertilizing
During the growth period after propagation, you can apply a thin cake fertilizer water every half month to help the branches grow. Before flowering, you can apply phosphorus and potassium fertilizer every 10-15 days to accumulate nutrients in the plant and produce flowers.
3. Pruning
Pruning after propagation of osmanthus trees usually involves pinching and cutting methods. Pinching refers to removing the topmost tender shoots to promote branching, while cutting involves pruning side branches, selecting strong ones to keep and pruning overly dense branches appropriately.
