Common jasmine is a fast-growing plant, often growing up to 2 feet each year. It is best planted in a pot near a house or walkway so that you and your guests can enjoy its fragrance. It will also attract beneficial pollinators to the garden, like butterflies. If you are growing jasmine in a cold growing zone, planting it in a pot can be helpful so that you can bring it indoors when the weather turns cooler.
In addition to dead or damaged leaves and stems, you can also remove stems that are growing out directly from the fence or other supports. Renovate overgrown jasmine by cutting back to the base. Jasmine grows vigorously and can withstand hard pruning.
If your jasmine has outgrown its space, you can cut the entire plant back to within 2 feet 61 cm of ground level. Select strong, healthy shoots to retrain on your wall or fence. Method 2. Do a hard pruning immediately after blooming. Remove all stems that have already flowered, bare lower stems, and dead or damaged leaves.
You can also let the vines hang over the edge of the pot. Indoor jasmine may bloom year-round, but requires a rest period during the fall. Remove dead flowers and branches as soon as they appear. If you don't get rid of dead flowers and branches, your jasmine will stop growing. Pinch off dead flowers and cut non-flowering branches down to the base of the stem. Try to move it to a place where it can receive more direct sunlight. Trim as necessary to prevent overgrowth.
Jasmine plants grow vigorously. Indoors, they will quickly overtake their pots if not trimmed regularly. Prune away 10 to 20 percent of new growth as needed weekly, except when the plant is blooming.
Follow up with a hard pruning when blooming has stopped. Give the plant a couple of weeks to recover before resuming your weekly trimming routine. Repot in spring only when completely pot bound. Jasmine plants tend to bloom best when they are slightly pot bound.
If your jasmine is in a larger pot, you may see lots of leaves and fewer flowers. Your jasmine's new pot shouldn't be more than 1 or 2 inches 2. Root-prune when repotting your jasmine. If you root-prune your jasmine, you typically can return it to the same pot rather than using a larger pot. Root-pruning can help you keep the size of your indoor jasmine under control.
Do not root-prune unless you top-prune as well. Method 3. Set supports about 2 inches 5. If you want your jasmine to grow freely up a wall or fence, your supports should be far enough out that the vines can twine around the supports and grow loosely. This will help prevent excessive dampness and rot, and make it easier for you to prune the lower parts of the vines.
Start young plants on bamboo canes. Jasmine plants typically are started in pots, then transferred to the garden once they've started growing vines. Set bamboo canes directly in the pots, and twine the young vines around these canes. Allow the plant to grow until its roots fill the starter or seedling pot, then move outside in early spring. Leave the vines trained around the bamboo canes when you move your jasmine outdoors. Make sure the plant is 12 to 18 inches 30 to 46 cm away from the wall or any solid structure, so it has enough room to develop a complete root system.
Use the canes to angle the vines up the support. Take the bamboo canes from the potted jasmine and weave them through the wires or wooden battens of your support to help train your vines in the right direction.
