Propagation Methods

Cutting Propagation

Cutting propagation is a method of reproducing jasmine using its branches, suitable for spring, autumn, and winter. The specific steps are as follows:

  1. Select healthy branches from the mother jasmine plant that are vigorous, not flowering, and 10-15 centimeters long. Cut them with disinfected scissors at a certain angle.
  2. Remove excess leaves from the bottom of the branches, leaving 1-2 at the top to facilitate photosynthesis and water evaporation.
  3. Prepare well-draining and breathable soil, a mixture of leaf mold, garden soil, river sand, etc., or add some loose materials like perlite and vermiculite to improve soil aeration and water retention.
  4. Dig small holes in the soil, and insert the branches 3-5 centimeters deep, with 3-5 branches per pot. Gently press the soil after inserting to ensure good contact between the branches and the soil.
  5. After watering thoroughly, place the potted plant in a shaded area, avoiding direct sunlight. Keep the soil moist but not overly wet, spray once a day to increase air humidity.
  6. After about 20 days, the branches will root, and new shoots will appear. At this point, increase the lighting time appropriately to promote photosynthesis and growth. When the branches grow to 20-30 centimeters, transplant them into larger pots or in the ground.

Notes on Cutting Propagation:

  • When selecting branches, avoid choosing those that have already flowered or are about to flower, as these branches have already consumed a lot of nutrients and water, hindering rooting.
  • When inserting into the soil, be careful not to damage the buds on the branches, as these buds are essential for growing new shoots and roots.
  • When watering, be careful not to water the branches to avoid rotting the tips or roots. Water moderately to avoid affecting the rooting effect.
  • Maintaining air humidity is crucial for promoting rooting. You can cover the potted plant with plastic bags or glass covers to create a small greenhouse effect. However, pay attention to ventilation to prevent bacterial growth due to high temperature and humidity.

Air Layering

Air layering is another method of propagating jasmine using branches to root in the soil, suitable for May and June.

  1. Choose vigorous branches with one to two years of growth from the mother plant and cut them with a sharp blade. The incision should be smooth to avoid damaging the branches.
  2. Keep a few leaves on the upper part of the cut branches, remove all leaves from the lower part, and make a small incision in the middle to facilitate rooting.
  3. Prepare a well-draining and fertile soil pot, press the incision of the branches into the soil, and cover it with a layer of fine soil, and water thoroughly.
  4. Place the potted plant in a semi-shaded area, keep the soil moist, and avoid direct sunlight and drying. Check the branches every few days to see if new roots have grown. If new leaves emerge, it indicates successful rooting.
  5. After the branches have grown new roots, cut them off from the mother plant and transplant them into another pot. Be gentle when transplanting to avoid damaging the new roots. Water promptly after transplanting and place in a well-ventilated area.

Notes on Air Layering:

  • When propagating through air layering, choosing healthy branches free from diseases and pests is crucial for the survival rate. Avoid selecting branches that have flowered, as their internal tissues may be damaged, affecting the survival rate. Careful selection and protection of branches can improve the success rate of air layering propagation and promote healthy plant growth.
  • Maintain appropriate soil moisture during air layering. Excessive moisture can increase the chance of bacterial reproduction, leading to branch rot and even causing diseases. Therefore, regular watering is needed to keep the soil slightly moist, while avoiding excessive irrigation to prevent waterlogging in the roots.
  • To successfully achieve air layering propagation, various adverse conditions, such as high temperatures, low temperatures, drought, and waterlogging, must be avoided. These conditions can have a detrimental effect on rooting.
