How to propagate peonies? Sharing a few common propagation methods
Peony is a herbaceous plant that is very popular in China, and peonies can be seen in many parks. Peonies actually have not only ornamental value, but also certain edible and medicinal value. They are a flower with relatively high economic value, and China now also has dedicated peony planting bases. However, many people do not know how to propagate peonies, so below the editor brings the propagation methods for peonies. Let's take a look!
1. Division propagation
Division propagation is the most common propagation method for peonies, and is mainly used for peonies grown for medicinal purposes. In autumn, dig out the mother plant with soil, and select peony heads with buds for propagation. First observe the peony heads, pick out those without buds and with pests or diseases, then cut the normal peony heads into pieces. Each piece of peony head must retain more than 2 strong buds. The peony head should not be too thick or too thin; if too thick, the main root is weak, its growth ability is not strong, and branching decreases. If too thin, the peony head absorbs nutrients poorly, and growth is hindered after planting. Cut as you plant. However, the division propagation method cannot be used continuously, because peonies are not suitable for continuous cropping, otherwise the disease incidence will increase, causing poor growth and increasing the mortality rate.
2. Seed propagation
Seed propagation is also a common propagation method for peonies. Peony seeds are mainly inside their fruit. When the seeds mature, the fruit cracks, and the seeds fall out of the fruit. The ripening time of peony fruit varies depending on the planting region, so everyone needs to pay attention to this. After harvest, seeds should not be stored for too long. It is best to sow immediately after harvest, because the moisture content of the seeds will gradually decrease as the sowing time is extended. This causes the seed germination rate to decline, making it difficult to take root and emerge. Before sowing, pick out poorly developed seeds, remove shriveled seeds by soaking in water, then soak the seeds to promote germination, do a good job in land preparation and fertilizing, control the sowing density well, and sow at the right time according to weather changes.
3. Cutting propagation
Although cutting propagation is not common, it is relatively simple. First select soil with good ventilation, sunlight, and drainage as the cutting bed, and loosen the soil. Then spread a layer of river sand on the soil as the cutting substrate. Before spreading the river sand, disinfect it first to prevent pests and diseases from affecting growth. Then from June to August, select branches with strong growth and no pests or diseases as cuttings. The cuttings should be about 12 cm long. Control the depth and insert the cuttings at the right time. After inserting, water thoroughly, cover with a greenhouse, and control the greenhouse temperature at 22 degrees and the humidity at about 85%. Roots can generally form in about one month.
4. Root cutting propagation
The last propagation method is root cutting propagation. The prerequisite for root cutting propagation is based on division propagation. When dividing in autumn, perform root cutting treatment on the plant. After root cutting, disinfect the cut opening of the plant to prevent wound infection and pest or disease problems. Then cut the roots into root segments of about 8 li, control the density well, and insert them into the planting ditch dug in advance. The depth of the ditch should be controlled at about 12 cm. After inserting, cover with fine soil and water thoroughly.
The above is a brief introduction to several propagation methods for peonies. The two most commonly used propagation methods for peonies are still division and sowing. Cutting and root cutting require a certain level of skill, because when cutting, it is necessary to ensure that the plant will not suffer other damage, and disinfection work must be carried out after cutting, so everyone must pay attention when using these two methods. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
