Quck answer
Night-blooming jasmine, also known as Cestrum nocturnum, is a fragrant flowering plant that blooms at night. Propagating night-blooming jasmine can be done through stem cuttings or seeds. To propagate through stem cuttings, select a healthy stem and cut it just below a leaf node. Remove the bottom leaves and dip the cut end in rooting hormone. Place the cutting in a pot with well-draining soil and keep it in a warm and humid environment. Water regularly and wait for roots to develop. To propagate through seeds, collect ripe berries and remove the seeds. Plant the seeds in a pot with well-draining soil and keep them moist. Germination can take several weeks. With proper care, your night-blooming jasmine will grow and bloom beautifully.
If you want to grow a new night-blooming jasmine plant, the easiest method is to propagate it by rooting a stem cutting from an existing plant. Night-blooming jasmine is also known as night-blooming jessamine and produces beautiful white blooms with the familiar jasmine fragrance. This plant grows in USDA plant hardiness zones 8 through 11, and in zones 8 and 9, where freezes occur, the foliage may die to the ground but will start growing again in springtime.
Rooting Cuttings
To root a cutting from a healthy night-blooming jasmine, choose a vigorous plant with new stem growth. This is because actively growing stems will produce roots quickly. You can take a cutting any time of the year when the plant has new growth.
Step 1
Disinfect the pruners by dipping them in rubbing alcohol and then drying them with a clean rag. This is important to prevent the spread of disease when taking a cutting.
Step 2
Take a small amount of rooting hormone and place it on a saucer or in a small container.
Step 3
Mix equal parts of peat and perlite and fill a small or medium flower pot with it. Make sure the pot has drainage holes. Soak the mixture and let the excess water drain. Using a pencil, poke holes in the planting medium a few inches apart and about 3 inches deep. Cut off the bottom of a clear plastic jug that fits over the pot.
Step 4
Using the pruners, make a clean cut below a node and about 6 inches from the tip of the stem. It’s best to take at least two cuttings for better chances of success. Take the cuttings early in the day and wrap them in a moist paper towel to transport them to your other supplies.
Step 5
Remove all the leaves from the bottom half (cut side) of the stem. Pinch off any flower buds and leave only two leaves on the cutting. This helps the cutting direct all its energy into developing roots.
Step 6
Roll the cut end of the stem in the rooting hormone on the saucer and coat about 1 inch of the end. Tap off the excess hormone and discard any leftover.
Step 7
Place the hormone-covered end of each cutting into one of the holes in the planting medium. About half, or 3 inches, of the cut end of the stem should be below the soil line. Prepare each cutting this way and firm the planting medium around the cuttings. Place two cuttings in each container so you don’t damage newly formed roots and can easily replant them in a larger container later.
Step 8
Mist the leaves of the night-blooming jasmine stems and cover the planter with the plastic jug. Put the cuttings in a bright spot but not in direct sunlight.
Step 9
Make sure to water the soil regularly and spray the leaves with mist. Ensure that the soil doesn’t dry out completely. Once the cutting starts to grow, it means that the roots have formed. It takes about eight weeks for the roots to develop fully and the cuttings to settle into the container. Once the roots have fully developed, you can re-pot them into a larger container or move them outside to an appropriate location.
