How to propagate the poinsettia
Abstract: This article introduces the propagation and cutting methods and timing of the poinsettia, as well as related information about green plants and flowers. Detailed information follows below.
When it comes to the poinsettia, I believe plant enthusiasts are not unfamiliar with it, especially for those who enjoy flower arrangement, as it is often encountered like "home-cooked meals." However, when it comes to cutting propagation, some friends may not be very clear.
Just a few days ago, a netizen asked me, saying she wanted to cultivate poinsettias but didn't know how to propagate them through cuttings. She wants to use them as wedding decorations this year, so she urgently sought my advice: how to propagate through cuttings.
Key points:
First, cutting time: The best time for propagating poinsettias through cuttings is from June to July. Since poinsettias are sensitive to cold, if the weather is cold, the plant may experience leaf drop and wither during the cutting process.
The temperature environment for cutting should generally be maintained around 25 degrees Celsius, which can quickly promote the growth of the rootstock. After cutting, the plant will usually take root within about one month. Since the flowering period of the poinsettia is around December, as long as the growth is good, it can bloom for display during the New Year's Day.
Second, cutting method: Directly cut branches for propagation, focusing on tender branches with a length of 1-2 nodes. If conditions permit, applying wood ash to the top of the cutting can help with rootstock growth and 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 shield the roots and tops, reducing water loss due to direct sunlight.
Third, cutting care: After cutting the tender branches of the poinsettia, fertilization is not necessary, but one thing that cannot be overlooked is watering to keep the soil moist. Water is key to root growth and also helps with later transplantation. Poinsettias require a lot of water during growth, and if there is insufficient water, it is difficult to take root.
From the perspective of plant growth, water is essential for the transport of nutrients in the rootstock and leaves. Therefore, if water is lacking during the cutting process, the leaves may drop. Generally, after cutting, water can be sprayed once every 2-4 days to keep the soil moist, allowing the poinsettia to accelerate root growth.
As mentioned above, the cutting of poinsettias is relatively simple, with the key being the supply of water. After the poinsettia takes root, during the later care process, it is appropriate to supplement with nitrogen or phosphorus fertilizer, which helps with leaf growth and flower blooming, achieving an ornamental effect. Poinsettias can be used for Christmas and festive decorations, symbolizing prosperity and thriving, so plant enthusiasts can also cultivate them at home using the above methods.
The above sharing of how to propagate poinsettias and the methods and timing for poinsettia cutting are for reference and suggestion.
