Propagation methods of Chestnut rose

Chestnut rose flowers can be propagated by division, cutting, grafting, sowing. Next, let's look at the details of propagation methods of Chestnut rose.

1. Plant division propagation of Chestnut rose

Chestnut roses can propagate by division. First, choose healthy, disease-free seedlings, then dig them out of the soil and plant them in soil rich in organic matter and well drained. After cuttings, carbendazim solution can be sprayed on the plants to help the seedlings adapt to the environment.

2. Cutting propagation of Chestnut rose

Chestnut Rose can also be propagated by cuttings. Cuttage propagation: Chestnut rose cuttings, spring, summer, autumn can be carried out (with autumn interpolation as an example). Make the bed. Choose leeward slightly overcast, fertile soil, sandy loam with watering conditions to make a bed, deep turn, bottom fertilizer, rake dry, do 1 meters wide, length unlimited slotting, watering enough water to be cuttings.Cut cutting.

Cut the lignified current year branches from the good mother trees that have produced fruit, cut 10-15 cm cuttings, cut them into horse ear shape, cutting depth is 2/3 of the cuttings, plant row spacing is 10 cm ×25 cm, and insert them on the seedbed observiously.

After inserting, a square plastic arch shed is attached to the seedbed, and the vent is opened. After freezing, the vent is closed in time. When the cuttings sprout in the second year, water is poured, the vent is gradually opened, and the film is removed about 30 days, and the seedlings can be released in autumn.

3. Grafting propagation of Chestnut rose

Chestnut rose can also be grafted and propagated. First, choose cuttings that have not suffered from pests and diseases, or chestnut rose as rootstocks. Then cut the same size wounds from the rootstocks and cuttings, stick them together, and secure them with tape.

4. Sowing propagation of Chestnut rose

Sowing propagation of Chestnut rose can be carried out in spring sowing and autumn. Chestnut Rose seeds have no obvious dormant period, the autumn seeds are sown immediately after maturity, and the germination rate and emergence rate can reach more than 90%. Autumn sowing, in September, the fruit is mature after the seed, immediately sown into the seedbed, in October, late seedlings. Transplant nursery in March the second year, the end of the year can be nurseries.

But in winter, the cold areas need to be covered with plastic film to prevent freezing. Spring sowing is appropriate from late February to early March. Seedlings emerge in early April, and transplants to the nursery from late May to early June. The day before sowing, the seeds are soaked in warm water of 50~60℃ for 12~24 hours. After taking out, the seeds are washed and planted, which can germinate 5 days earlier and improve the germination rate.
