How to Propagate Forsythia by Cuttings
A bit of knowledge to share with you on how to propagate Forsythia by cuttings and an introduction to the green plant flowers, including the methods and timing of Forsythia cutting. Here are the details to follow.
It is possible to propagate Forsythia through cuttings, as the branches root easily and the survival rate of seedlings is high. The methods of propagating Forsythia include cuttings, division, and layering, with the cutting method being the most commonly used. Forsythia is a deciduous climber of the Oleaceae family, blooming before other flowers in early spring, and quickly growing leaves after the flowers. Below is a specific introduction on how to propagate Forsythia through cuttings.
I. Soil-based Cutting Method
1. Cutting Time
Forsythia can withstand severe cold and drought. It can be propagated in soil in spring, summer, and autumn. Spring cuttings of Forsythia can root quickly, with the optimal temperature for survival being 20 to 25°C, making spring the best season for propagating Forsythia. This can be done at the end of March. Summer and autumn cuttings are best done between July and September.
2. Selection and Treatment of Cuttings
Usually, 12 to 15 cm long semi-hardwood branches from the current year are used as cuttings, which should be robust and healthy. The length of the cuttings is also determined based on the desired plant shape. If it is intended for a potted plant, the cuttings can be slightly longer.
The tip of the cutting should be pruned, leaving a small amount of foliage at the top, and all leaves below one-third of the cutting should be removed.
3. Cutting Process
The cutting depth into the propagation medium should reach 1/3 to 1/2 the length of the cutting, then press the soil surface flat.
4. After-Cutting Care
After cutting, water thoroughly and provide shading protection. Maintain soil moisture, and cover with plastic film for 10 to 15 days to keep warm and moist. It is also necessary to frequently open it to maintain air circulation. In about 30 days, the cuttings can root and survive.
II. Water-based Cutting Method
Forsythia can also be propagated in water, and this can be done in any season with a temperature of 15 to 20°C. The cuttings should be 8 to 12 cm long, with about 2 to 4 nodes, and should be from the current year's strong branches, with the lower leaves appropriately removed.
Usually, the cuttings can root in 35 to 40 days, and after the roots reach 3 to 5 cm in length, they can be transplanted into soil for cultivation.
The above information provides a complete introduction to how to propagate Forsythia by cuttings and the methods and timing of Forsythia cutting for everyone to learn and understand!
