How to Propagate Azaleas from Cuttings? Detailed Guide to Cutting Time and Methods
Azaleas are also known as shan zhizhu, shan shiliu, yingshanhong, zhaoshanhong, and Tang azalea. Legend has it that long ago there was a cuckoo bird that cried day and night until it coughed blood, which stained the flowers all over the mountains red, and that is how the azalea got its name. The azalea is a typical indicator plant of acid soil in central-southern and southwestern China. It generally grows in sparse mountain thickets or under pine forests at altitudes of 500-1200 m, usually blooms in spring, with 2-6 flowers per cluster, and the flowers come in colors such as pale red, apricot red, snow blue, and white. Today, the editor will talk about the cutting time and cutting methods for azaleas, hoping it will be helpful to everyone.
1. Cutting time for azaleas
Azalea cuttings are generally taken in late spring and early summer, but because azalea varieties differ, the time when they sprout new shoots also varies. Similarly, Western azaleas are in late May, spring azaleas in early June, and Eastern azaleas and summer azaleas in mid-June. In the plum rain season of Jiangnan, the air is mild and humid, making planting in Jiangnan even more favorable for the cuttings to heal and take root.
2. Cutting methods for azaleas
First, select a robust mother plant, cut off the selected lush upward-growing branches and leaves from the base, and remove the lower leaves at the same time, keeping only the top 2-3 leaves. After pruning, tie the branches together, soak them in warm water for half an hour, and poke a few small holes in the prepared potting soil. Insert the soaked branches into the holes and press the soil firm with your fingers. After cutting, water thoroughly and place in a cool place. If the humidity is relatively low, you can wrap the flowerpot with plastic film. After about 21 days, the rooted cuttings will have adapted to the new environment, and then they can be moved to a bright place and given appropriate sun exposure.
3. Cutting care for azaleas
After cutting, azaleas will take root in about 50-60 days. Once they have rooted, the top layer of plastic film can be removed to ensure air circulation. Generally, water once in the morning and once in the evening. After about 30 days, the root system will become full, and then they can be potted separately. When potting separately, it is best to plant them in pots with a diameter of 10 cm, and after potting, place them in a warm, sunny place.
How to Propagate Azaleas from Cuttings? Method for Propagating Azaleas from Stem Cuttings
Flower friend: The company did inventory today, and I saw a whole row of azaleas planted in the flower garden. They were very beautiful, and I couldn't resist breaking off this branch. Can it still be propagated successfully from a cutting now? How exactly should I do it? Location: Xiamen, temperature around 10-20 degrees.

Editor: First, I can tell you very responsibly that azaleas can indeed be propagated successfully from stem cuttings, but the azalea branch you broke off and the timing are both unsuitable. The correct operation method is as follows:
1. Branch selection
Azalea cuttings can use softwood cuttings or hardwood cuttings, but you cannot choose branches that have already bloomed or grown long shoots and buds, because nutrients have already begun to be consumed, which will affect the survival rate.
Use your hands to pull the azalea branch down from the base (the part connected to the stem), generally 4-6 cm long, keeping 4~5 leaves at the top. If the broken end is ragged and hairy, it should be trimmed smooth with sharp scissors, and then inserted into the soil to a depth of one third of the branch length, with a plant and row spacing of generally 5~6 cm.
In addition, if using softwood azalea cuttings, the branches should be selected from robust shoots newly grown in the current year.

2. Cutting time
Hardwood cuttings are generally taken from April to May, using last year's old branches before flowering, while softwood cuttings are best taken during the plum rain season. Because the air humidity is high at this time, growth is promoted quickly, generally from late May to June.
3. Cutting seedbed
Before cutting, it is best to prepare a seedbed first. For home cuttings, you can use a shallow pot or a clay pot with a diameter of 20~23 cm. The bottom of the pot must be lined with broken tiles to facilitate drainage, and put mountain soil (the soil azaleas like most) into the pot to about eight-tenths full.

4. Cutting care
After insertion, spray with a fine-nozzle watering can, water thoroughly, and do shade work within 7~10 days. It is best to place them indoors to prevent sunlight exposure, and spray with a mist sprayer 6~7 times a day to increase the air humidity on the leaf surface of the cuttings.
After 10 days, a little light can be let in in the morning and evening, and spray 3~4 times a day. After about 15 days, if the cuttings are still relatively plump and the leaves do not fall off, it means the broken end has grown fine root hairs, and generally rooting is complete in 25---30 days.
Some superior varieties are not easy to survive from cuttings, and vermiculite can be used as a medium for cutting. The method is the same as above. If automatic intermittent misting can be added to keep the leaf surface of the cuttings moist regularly, the survival rate can reach more than 95%.
How to Propagate Azaleas from Cuttings
Cutting time for azaleas
Azalea cuttings are best taken in late spring and early summer, but different varieties sprout new shoots at different times. Usually Western azaleas are in late May, spring azaleas in early June, and Eastern azaleas and summer azaleas in mid-June. But in the plum rain season of Jiangnan, the air is mild and humid, which is more favorable for the cuttings to heal and take root.
Cutting methods for azaleas
First, select a robust mother plant.
Select lush upward-growing branches and leaves, and cut them off from the base. Remove the lower leaves and keep only the top 2~3 leaves.
After pruning, tie the leaves together and soak them in warm water for 30 minutes.
Poke a few small holes in the prepared potting soil.
Insert the soaked branches into the holes and press firm with your fingers.
Water thoroughly and place in a cool place. If the humidity is relatively low, you can wrap the flowerpot with plastic film. After about three weeks, the rooted cuttings will adapt to the new environment, and can be moved to a bright place and given appropriate sun exposure.
Cutting care for azaleas
They take root 50~60 days after cutting. Once rooted, the top layer of plastic film can be removed to ensure air circulation. Water once in the morning and once in the evening. After another month, when the root system is full, they can be potted separately, preferably in pots with a diameter of 10 cm. After potting, place them in a warm, sunny place.
