The water needs of winter jasmine are highest during early spring through summer.

It is best to water it 2-3 times a week, especially during hot weather.

But, gradually reduce the frequency of watering as the weather starts to change.

Though to late winter, this jasmine species only needs to be watered once a week.

To increase the growth of the plant, add fertilizer after every two weeks, during spring and summer.

How to Propagate Winter Jasminum?

The propagation techniques used for Jasminum nudiflorum are:

Layering:

  • Layering is performed in various ways.
  • The simplest technique is to select a few young and flexible shoots to easily be bent down to the ground.
  • Preferably, they should be on the outer side of the plant.
  • Leaving a distance of about 1’ foot from the tips of shoots, make 1” – 2” inch long incisions along the stem.
  • Now apply a hormone rooting compound on both the surfaces of the incisions, put layered areas of the green stems in shallow trenches, no more than 4” – 6” inches deep, and fasten them with a bamboo cane.
  • Fill the trench with soil and water, if dry.
  • The trailing branches of the plant root when they come in contact with soil.

Semi-Hardwood Cuttings:

  • To take semi-hardwood cuttings, use sharp, clean hand pruners (our favorite pruners) and choose healthy material from the season’s growth.
  • Place the cuttings in a plastic bag and put the bag in a hot or shaded area for a few hours.
  • However, do not leave the cuttings for more than 12 hours.
  • When ready to plant, trim the cuttings into 4” – 6” inch pieces; cut just below the leaf node.
  • Remove any soft tips and lowest green leaves and dip them in fresh root hormone powder from the bottom.
  • Plant the cuttings in a container filled with cuttings compost and water well.
  • Allow them to drain and then place the pots in a greenhouse.
  • Semi-hardwood cuttings are best to take in the morning.

Control weed issues with mulch.
