Jasmine is a woody climber that produces flowers in the summer or the winter depending on the variety you choose. Winter flowering jasmine such as the Jasminum nudiflorum produces stunning yellow flowers through winter and spring while the summer flowering varieties, such as Jasminum officinale with its white flowers and beesianum with its red flowers, produce stunning and often scented flowers in summer.

When planting it is best to do it in the spring or autumn if you have a summer flowering Jasmine, although the perfect time is probably autumn and for a winter Jasmine planting in spring would be ideal.

Once fully established, most hardy Jasmine varieties will span between 3 and 5 metres for height and spread, however, if grown in containers this reduces its height but it’s worth noting that they do adapt very well when grown in pots and containers. This is an incredibly popular plant for the UK because of its hardiness to frost although they do prefer a more sheltered position.

Winter Jasmine is more tolerant of partial shade than the summer varieties

When planting Jasmine you need to provide fertile, well-drained soil with partial sun or full sun. If you are growing summer Jasmine it requires a slightly sheltered spot with full sun, preferably facing south or southwest. By comparison, if you are growing winter Jasmine it is more tolerant of partial shade and thrives with south-east or north-west direction.

Growing frost hardy varieties under glass over winter

Growing frost-hardy but more tender varieties (such as Jasminum Trachelospermum) in colder areas where they may not survive, can be kept in a cold greenhouse or an unheated conservatory over winter using nothing more than a small greenhouse heater to keep the frost to a minimum.

Growing Jasmine in containers and pots

Jasmine makes for particularly lovely specimens in containers but if you do plant them in a container be sure to add extra drainage holes because they need well-drained soil. The holes should be covered with crockery or stone to prevent the compost from washing through it or worst the holes from becoming blocked.

Be sure to leave space at the top so that you can water the plant and put it somewhere it has access to bright, filtered light. In terms of compost, we recommend John Innes potting compost which is soil-based with a little grit mixed in to improve drainage.


On-going Jasmine care

Watering

Once you have planted your Jasmine you should water it freely in the spring and in the summer when the plant is most actively growing, this is especially important for container-grown Jasmine that can dry out quickly on warmer days.

Come winter you can reduce the amount of watering. As an outdoor plant, it won’t need a lot of watering in the winter unless it is a particularly dry season, you may not even need to water it at all because they usually cope quite well with very little care. If you bring your Jasmine indoors or you have it in a greenhouse it will only need sparse watering once the soil has become dry. Jasmine grown in containers outdoors can also be treated in the same way, only watering when required.

Feeding Jasmine plants

Growing Jasmine in a container requires monthly feeding with a liquid feed that has high potassium levels, usually, a tomato fertiliser is more than good enough, and usually the most affordable way to go about it.

With Jasmine that is grown in the ground, you can add a balanced, granular fertiliser such as Growmore (which is usually the cheapest option) plus you can also use it on most other plants in your garden. You can also feed with something that is high in potassium, such as sulphate of potash. Alternatively, you can add seaweed feed if you have some laying around in your shed and if you have a wood burning stove you can also use wood ash as an organic source of potassium.

Pruning and Training

Pruning Jasmine by flowering time

Summer flowering jasmine

With a summer flowering Jasmine plant, you should prune it right after it flowers which is usually in late summer to early autumn. With most varieties of summer flowering Jasminum, the earliest flush of flowers will develop on the previous year’s growth but a later flush will develop just on the tips of the current growth from the current year. By pruning at the appropriate time you allow the opportunity for the new growth to mature and flower the following season.

Pruning Jasmine is more about when to prune jasmine rather than how. Summer and winter flower Jasmine need to be treated differently. learn more now on pruning Jasminium

Winter flowering Jasmine

If you have a winter flowering Jasmine, such as Jasminium nudiflorum, it is best to prune them in the spring, directly after it has finished flowering in the winter. For Winter Jasmine, the flowers develop on the previous year’s growth so pruning directly after flowering provides new growth over summer that will produce the yellow flowers in winter.

When to prune Jasmine

Hard pruning

Both varieties of Jasmine, winter and summer flowering, will tolerate hard pruning on occasion and will generally respond very well. If your plant has outgrown its space you can cut it back to approximately 2ft (60cm) from the base. Remove any unwanted shoots and leave the strongest of shoots to be trained into the new framework.

General pruning

Given that Jasmine is a climbing plant you can train the branches as they grow to the shape and framework that you prefer. You can choose to prune away unwanted shoots to facilitate more vigorous strong shoots or simply leave the ones you have to grow along something such as a trellis or a fence in your garden.

Propagating by Taking Cuttings

If you have a particularly successful plant and want to have a go at propagating some new plants this can be done by either layering or by taking hardwood cuttings, and this is probably the best way to go about it.

Your outdoor varieties are best propagated if you take a hardwood cutting during the winter, this is probably best done either just after the leaves have dropped in late autumn or late winter, just before it comes into bud. If you have a more tender variety you can take a semi-ripe or softwood cuttings in the spring or summer, however, this method is generally used for indoor varieties of Jasmine.

Taking the cuttings

Once you have the cuttings in question, remove any extra leaves so that there is simply one pair at the top, and place the cutting directly into a container of compost or directly into the ground. If you are growing your cuttings in pots, cover the top of the container with a plastic bag, plastic cup, or a plastic lid of sorts, making sure that the cover does not touch the cutting directly. From there each of your containers will create small greenhouses and eventually your cutting will establish a root system and be ready for transplantation.

Taking hardwood cuttings is usually an easy but long process, although generally the most successful. More often than not, if you take cuttings in the autumn, they will be ready the following autumn to transplant into another pot or into the ground.
