How does the poinsettia propagate
About the propagation of poinsettia and the precautions for cultivating poinsettia, the following is the introduction of related green plants and flowers. Next, the editor of this site will introduce to everyone.
Speaking of poinsettia, I believe that flower lovers are not unfamiliar with it, especially for those who enjoy flower arrangement, it is often encountered as "home cooking", but when it comes to cutting propagation, some friends may not be very clear.
Just a few days ago, a netizen asked me, saying that she wanted to cultivate poinsettia, but did not know how to propagate by cutting. She wanted to use it as a wedding decoration this year, so she urgently sought my advice: how to propagate by cutting.
Key points:
First, cutting time: The best time for propagating poinsettia by cutting is from June to July. Because poinsettia is afraid of cold, if the weather is cold, the plant may wilt and lose leaves during the cutting process.
The temperature environment for cutting should generally be maintained at around 25 degrees Celsius, which can quickly promote the growth of the rootstock. After cutting, it will take about 1 month to root. Since the flowering period of poinsettia is around December, as long as it grows well, it can bloom for appreciation during the New Year's Day.
Second, cutting method: Directly cut branches for propagation, mainly using tender branches, with a length of 1-2 nodes being ideal. If conditions permit, you can apply wood ash to the top of the cuttings, which helps the growth of the rootstock and can reduce diseases.
During the cutting process, try not to break the tender branches. At the same time, plant them in sandy soil to avoid excessive sunlight, which can cause the tender branches to wither. Use branches to shade the roots and tops to reduce water loss from direct sunlight.
Third, cutting care: After cutting the tender branches of poinsettia, there is no need to fertilize, but one thing that cannot be lacking is watering to keep the soil moist. Water is the key to rooting and is also very helpful for later transplantation. Poinsettia requires a lot of water during growth, and it is difficult to root if there is not enough water.
From the perspective of plant growth, water is the key to promoting the transport of nutrients in the rootstock and leaves. Therefore, if there is a lack of water during the cutting process, the leaves may fall off. Generally, after cutting, you can spray water every 2-4 days to keep the soil moist, allowing the poinsettia to accelerate rooting.
As can be seen from the above, the cutting of poinsettia is relatively simple, with the key being the supply of water. After the poinsettia has rooted, during the later care process, you can supplement nitrogen or phosphorus fertilizer, which helps leaf growth and flower blooming, achieving the effect of appreciation. Poinsettia can be used for Christmas and festive decorations, symbolizing prosperity and thriving. Therefore, flower enthusiasts can also cultivate it at home according to the above methods.
The above is an introduction to how to propagate poinsettia and the precautions for cultivating poinsettia, which can be used as a reference suggestion for everyone.
