Jasmine is a popular plant that grows in most climates around the world and there are different varieties. They are native to Europe, Africa, and Asia, and grow well in warm climates. Learning how to propagate Jasmine will keep you from relying on the nursery. Below, you will also find a few simple care tips that can make it easier to grow the plant.
Methods of Propagation
The two most successful methods are sewing seeds and taking cuttings. Whichever method of propagation you choose, the care techniques required will be the same.
You can buy Jasmine seeds for propagation online, from a nursery, or you can collect them yourself from a mature plant. Before buying or collecting, decide which type you want.
There are over 300 different varieties. Some of the varieties available are shrubs, those that climb, ones that have a strong fragrance, and those that are highly toxic to humans and pets.
In the late summer, the plants will produce a bean-like seed pod. They can break open at any time and spill seeds everywhere, so the best method of collection is gently attaching a sandwich baggie right above the seed pod using a twist tie. This way, when the pod explodes you will catch all of the seeds. When the seed pod begins turning brown you will know it is mature and is about to expel its seeds.
Soak the jasmine seeds in warm water overnight before planting. To improve success of the seeds germinating you should start them off in seed trays. Use a seed starting mix and cover the seeds lightly with soil. Keep the seeds at 70 F with 8 to 10 hours of indirect sunlight a day.( If you cannot maintain this temperature, place a heating pad set on low underneath the seed trays.) Fill a clean spray bottle with filtered or rain water and mist the seeds daily. Never allow them to dry out or become too soggy. Seeds can be slow to germinate and may take as long as one month.
If you want to start your seeds inside and move them outside in the spring, start the seeds about six weeks before your last hard frost. Otherwise, you can start the seeds at any time of year.
Rachel Klein, gardening expert, gives the following advice: "Once the the seedlings have reached 3 inches in height they can then be either potted up into individual containers or planted out in the garden when temperatures reach 70 F during the day and 50 F at night."
Another simple way of propagating jasmine is by growing it from cuttings. This is easier than you might think. Start by taking a cutting from a plant when there are no flowers on it. Ideally, this should be done in late summer to early fall. Using sharp scissors, take a 2 or 3 inch section of jasmine and snip it off the plant right below a leaf. Make the cut at a 30 degree angle.
Remove the bottom leaves to leaf nodes. Then dip the cut end of the cutting into rooting powder. Press the cutting into a moist, medium-like sterile potting soil; ideally a combination of vermiculite, perlite, and peat. Never use garden soil, which may be contaminated with bacteria or harmful microbes. Plant the cutting at a depth of one inch.
Place your container in a room that gets good light but no direct sun. Keep the cuttings at 70 degrees F, using a heating pad set to low underneath the pot if this temperature is not possible. Fill a clean spray bottle with filtered or rain water, and mist the cuttings daily to keep them moist and keep the humidity up. Alternatively, you can cut some ventilation holes in a ziplock baggie and place it overtop of the cutting to maintain a high level of humidity.
If you're trying to grow jasmine by taking cuttings, you need to take more than you need. Not all of these cuttings will take and it's always better to have more than you need.
Ideal Conditions for Jasmine
Jasmine grows best in positions that have full sunlight, although it also grows well in partial shade. You will have more success with a moist soil that drains well. Adding leaf mold to the soil can improve the conditions and improve growth.
Pick a space that is big enough to accommodate the mature size of your jasmine, this is dependent on the variety you have chosen. Dwarf Jasmine (Jasmine minima) will only grow to 6 inches tall, while some varieties can grow to be 15 feet tall.
Caring for Jasmine Plants
You should ideally plant them outside between June and November. If you are planting more than one plant together, space them around 8 feet apart so that they have enough space to grow. Adding fertilizer in the spring will help the plant to grow. For best results, use an organic fertilizer such as leaf mold or compost. However, a commercial preparation of 1-2-1 works well also.
When planting young plants you should tie them to supports to ensure they don't get damaged by the wind. Pinch out the tips of the plants to help stimulate growth.
It's important to water the plants regularly, and you should make sure the soil is kept moist during the summer months. During the winter, however, you don't need to water quite as often. During the spring, add fertilizer to the water to help the plant along.
Rachel's points out: "Watering is important but you shouldn't water the plant too often. Watering too often can cause root rot which can kill the plant."
Regular pruning is required to prevent the jasmine plants from getting too big. Pruning methods will depend on the variety, as well as the plant's purpose.
Rachel suggests: "Jasmine needs heavy pruning to keep it shapely. Heavy pruning should be done right after the plant has finished flowering, usually in late summer to early fall."
