How to Grow Jasminum multiflorum (Downy Jasmine)? Growing Methods and Precautions

Jasminum multiflorum has very beautiful flowers and a very pleasant fragrance. Many people are willing to grow a pot of it at home, but find that after planting it, all kinds of problems appear. So how exactly should Jasminum multiflorum be grown? What do we need to pay attention to when cultivating it? Let's take a look together below.

How to Grow Jasminum multiflorum

1. Planting: For potted Jasminum multiflorum, every 2-3 years it should be repotted in March or after flowering. The potting soil can be mixed with 2 parts garden soil, 1 part compost, and 1 part sand.

2. Fertilizing: Apply 20% cake fertilizer water once a week. In summer, apply phosphorus and potassium 2 additional times to promote the strengthening of new shoots and flower bud differentiation.

3. Watering: Water to the extent of keeping the potting soil moist. When the air is dry, spray water around noon to increase humidity. In early November, move it into a greenhouse, 4. a sunny spot, or inside a sealed balcony, and water as appropriate so the soil does not become too dry.

During the growing season, apart from shading during the midday hours of midsummer, it should be given ample light at all other times.

Growing Methods and Precautions for Jasminum multiflorum

I. Growing Methods for Jasminum multiflorum

1. Water and fertilizer management: For watering Jasminum multiflorum, it is generally best to keep the potting soil moist, and watering should be done in moderation. When the air is relatively dry, you can increase the air humidity by spraying water. After autumn begins, watering should be reduced, just ensuring the soil does not dry out.

Fertilizing is generally done once every 7——10 days with fertilizer water. In summer, apply phosphorus fertilizer 2 times, which can promote the growth of flower buds. Fertilizing should stop in autumn.

2. Light and temperature: Jasminum multiflorum likes a warm growing environment with plenty of sunlight. Generally, during the growing season it needs to be given ample light, but in summer care should be taken to shade it, especially at noon when the light is strong and the temperature is high, when shading from sunlight is even more necessary.

In winter, care should be taken to keep it warm. It is best to place it indoors in a warm place for care, and you need to find a spot with sunlight.

3. Propagation methods: Jasminum multiflorum is mainly propagated by cuttings, carried out in spring and summer, and it propagates relatively quickly. In addition, layering propagation can also be used.

II. Precautions

1. Repotting: Potted Jasminum multiflorum needs to be repotted, generally once every 2 years——3 years, usually in early spring in March or after flowering.

2. Pruning: Pruning of Jasminum multiflorum is generally done together with repotting. You need to prune the diseased, weak, and dead branches of Jasminum multiflorum, as well as cut off old roots and branches that have already flowered, to promote the growth of new branches.

3. Pests and diseases: During the growing period, Jasminum multiflorum will have insect pests, mainly leaf-rolling moths and red spider mites, which need to be controlled promptly. Generally, chemical agents can be used for spraying and killing.

Reasons Why Jasminum multiflorum Does Not Bloom

1. Being placed in a shaded spot for a long time causes the leaves to become leggy and thin, while flower bud differentiation and flower bud opening both require direct sunlight. Therefore, jasmine should be placed outdoors in direct sunlight.

2. If too much nitrogen fertilizer is applied, it causes the leaves to become leggy and affects flower bud formation. Therefore, in the early stage before budding, control the application of nitrogen fertilizer, appropriately apply phosphorus fertilizer such as bone residue, fish bones, rice-washing water and other composted fertilizers, and appropriately control water, and it will be able to bud and bloom.

3. Branches and leaves being too dense creates excessive nutrient consumption, which inhibits flower bud formation. Combined with whole-plant pruning in April~May, this can make the branches and leaves of the jasmine well-spaced and promote flower bud differentiation.

4. Too much watering, water accumulation in the potting soil, too low temperature, and exposure to rain outdoors during the budding period can all cause bud drop. Prevention and control methods: control moisture, loosen the soil appropriately, and avoid direct heavy rain, etc.

How to Prune Jasminum multiflorum

1. After flowering, prune away the spent flowers together with about the 4 pairs of leaves below them. This part has strong sprouting ability and can produce more side branches and more flowers, but it should be handled flexibly according to the length of the flowering branch, because leggy branches need to be cut back a little more heavily, trying to maintain a good plant shape with the plant. This not only controls leggy branches but also increases the overall ornamental value. Slender branches can be cut from the connection point between the side branch and the main branch to avoid consuming too many nutrients.

2. Before spring sprouting, appropriate pruning should be carried out, removing elongated branches, weak branches, and overly old branches, and appropriately shortening healthy branches. 3. If new branches have already emerged and are growing well, pinch them when they reach more than 10 cm to promote a second flush of new shoots and more flowers.

3. After each flowering, promptly remove the spent flowers, appropriately trim away overly long branches, and also apply fertilizer once. How much to cut is generally determined by plant height and personal preference, generally between one to three nodes below the flower. If it is a non-flowering elongated shoot, more should be cut.

4. Pruning should generally be done on sunny days together with leaf thinning, and diseased branches should be cut off at the same time.

If you want Jasminum multiflorum to grow well, you need to prune it regularly, but pruning still requires technique. If you prune randomly, it will not only fail to achieve a beautiful effect but will also have the opposite effect. However, today I have already introduced the techniques to everyone, so you can prune according to the methods, and then you will be able to see beautiful Jasminum multiflorum.
