Propagation method of Gardenia bonsai

The cultivation of gardenia bonsai is mainly based on cutting propagation, but also can be striped, split or sowed. Cuttings can be cut with 1-2-year-old strong branches in March-April, with 10-12 cm long, uniform nodes at the lower end, 1-2 pairs of leaves at the upper end, 23 depth, B permeable after cutting, and often maintain a certain humidity, and can take root in April-May. Cutting with tender wood in rainy season, cuttings 8-10 cm long, leaving 2 pairs of leaves in the upper part, using 0.0025-0.005% indole acetic acid or 2. 4D treatment of the incision can promote the formation of healing tissue and increase the survival rate by more than 90%. A shed is needed for shade after cutting.

In the south, a water insertion method is used to propagate, using the current year's twigs, which are 12-15 cm long, soaked in clear water up to 12, change the water once a day, and put it in the semi-shade. B can produce new roots in about 20 days. Striping propagation is carried out from March to April, usually using the branches of 3-year-old strong mother trees to be ditched and buried in the soil, which can take root in about 30 days, and then be planted separately in the following spring.

Gardenia is mainly propagated by cuttings, and it can also be propagated by pressing, dividing plants, and sowing.

1. Cuttage propagation

From May to June, select semi-lignified, fully developed twigs, cut them into 10 mures 15 cm long, soak the base with 1000 mg / kg naphthoic acid for 3 to 5 seconds, cut them in acid soil with strong water and fertility conservation, generally use 3 portions of rotten leaf soil or mountain mud, 1 part of sawdust, peat or river sand, take root about 1 month after planting, and transplant after 50 days.

The method of water insertion is often used in summer in the south, which is carried out from April to July. The cut cuttings, which are 15 centimeters long and with 2 or 3 leaves on the top, are inserted on the basket lid or perforated plastic board, and the lid or plastic plate is floated on the surface. The upper part of the insert can be exposed to the water. Put it in the semi-shade after insertion and keep the water temperature for 16-18 ℃. New roots can grow in 20 days. When the temperature is high, change the water frequently, change the water once a day, can not make the water deteriorate. When the root is 2-3 cm long, it can be transplanted.

2. Striping propagation

Most of them are carried out from May to June. Select 1-year-old, 2-year-old strong branches, 25 cm long, pressed into the soil 3 cm 5 cm, about 1 month can take root, 2 months later can be cut off from the mother. Can also be high pressure, that is, on the adult gardenia, choose 2-3-year-old strong branches ring peeling 1cm, and then wrapped in moist peat, the outside wrapped with plastic bags to keep the soil moist, about 40 days can grow new roots, 2-3 months later cut off the mother.

3. Ramet propagation

In May, there are 2 or 3 branches growing side by side at the base of the root, which can be cut from the root with a knife, and each ramet has fine roots. After the wound is coated with plant ash, it can be planted separately.
