Jasmine: planting cultivation maintenance and pruning

The choice can be made on one of the many species of deciduous or evergreen jasmines, whose flowering, pink, white or pink, blooms according to the case over the different seasons. Some are very fragrant, others more discreet. But whatever it is, jasmine is a climbing or bushy shrub with starry flowers of great delicacy that nicely adorns low walls, trellises, pergolas, tree trunks and even wire netting, supports to which it brings an exotic note. Let’s find out how to plant a jasmine and then maintain it so that it thrives for many years. Let’s also look at the pruning method for jasmine, knowing that it should never be too harsh.

Plant a jasmine

Jasmine enjoys any good garden soil as long as she stays fraîchegood drainedand that she is very rich in organic fertilizer. Stony soil is best suited for shrubs grown in the South. Care must be taken to avoid any risk of stagnant water because this shrub hates having its roots bathed.

He likes them sunny situations good sheltered from cold winds but in regions with a very hot climate, it can be installed in the sun or in a semi-shaded corner.

It is a shrub that is chilly, not tolerating temperatures below -4°C. Small special mention for Winter Jasmine (Jasminum nudiflorum) that can be installed in all our regions because of its great hardiness. However, a winter veil should be kept close at hand in case of exceptional cold.

Planting period

Jasmine can be planted either in autumnthat is in spring. However, it is preferable to wait until spring to plant the less hardy species, in order to prevent them from spending their first winter in the cold.

Method of planting jasmine

In the groundit is right to :

  • Dig a sufficiently large hole, around 2 to 3 times the width of the root ball,
  • Place clay pebbles or gravel at the bottom of the hole to ensure sufficient drainage,
  • Prepare a mixture of topsoil, potting soil and organic fertilizer,
  • Install the foot in the hole, tilting it slightly to point it towards the wall or any other support,
  • Fill the hole without damaging the roots with enriched soil,
  • Pack well around the foot,
  • Water copiously.

We can then install a mulch to preserve the freshness of the earth. All that remains is to take care of the trellising of the jasmine branches.

If one wishes plant a jasmine in a potwhich is quite possible, you must file a drainage layer sufficient to fond and ensure that it is perforated. The container must measure at least 50 cm in diameter. The ideal substrate is made up of equal parts potting soil suitable for plants around the Mediterranean or potting soil and topsoil. Once the jasmine is installed in its container, it is essential again to water copiously.

The pot is then placed at the foot of the chosen support and all that remains is to attach the stems with ties that should not be too tight.

Caring for a Jasmine

After planting a jasmine, watering should be followed so that the shrub can take root and grow. If it is planted in a pot, it is approximately twice a week that it is necessary to water because the substrate dries much more quickly in these conditions. Once the shrub is well rooted, there is really little to care for.

Overwintering a potted jasmine

As soon as the first frosts are imminent, if you live in a region with a harsh climate, it is essential to overwinter your jasmine in a bright room where the temperature is about 15 or 16°C. Hence the interest of having it installed in a tank and not in the ground. If there is no possibility of bringing it inside (lack of premises, shrub planted in the ground, etc.), it is essential to protect it from the cold using a winter sail and a good layer of Straw placed at his feet.

Trellis some jasmines

When planting, care is taken to help the branches move towards the support. Thereafter, we limit ourselves to the trellising of the new shoots. Some varieties of jasmine with tendrilsthey do not need to be attached to cover a support.

Water your jasmine

Between two waterings, the soil must have dried out somewhat. We water more frequently as soon as the flower buds appear and in case of extreme heat of course, without drowning the roots. To save water, the good idea is to install Plant ground cover all around the foot of Jasmin or to opt for a mulch.

Fertilize the land

From April to September, it is useful to dilute in water a low nitrogen fertilizer like the one intended for roses, for example, twice a month. Fertilizers are stopped during the plant rest period.

Repot a jasmine

Repotting of container grown jasmine is only necessary every 3 years, every 2 years if it grows very quickly. It can be carried out either before winter, or in spring. This allows him to offer a bigger jar and of completely renew its substrate. It is therefore beneficial for its health and growth.

Monitor the possible presence of diseases and parasites

Jasmine is not not particularly sensitive diseases and does not attract many pests. However, we can fear aphids and mealybugs.

Mealybugs must be eliminated manually using a gauze previously soaked in90° alcohol then we spray the jasmine every 15 days for 2 months with a mixture of know black and lukewarm water or soap, water and vegetable oil (rapeseed for example). These natural preparations are non-aggressive for the shrub and are also perfectly suited in the event of an attack by aphids.

Cut a jasmine

We are satisfied with a annual light pruning so as not to harm the jasmine. It allows the shrub to flower generously year after year but also to maintain a bushy habit. Pruning the jasmine is also necessary to control your growth. This therefore consists of eliminating dead wood, dry twigs, broken or damaged stems and the least vigorous branches in favor of the strongest.

A slightly larger size without being too severe can be carried out every three years around in order to tame the port of jasmine. Here again we wait for the end of flowering to get down to it because it is not recommended to cut back the branches until they are completely deflowered. A clean cut is recommended:

  • Just above vigorous new growth that you want to keep or above a large bud,
  • To eliminate a few excess branches,
  • To pull out the layers, that is to say the shoots that grow spontaneously at the foot of certain varieties of jasmine.

Subsequently, once the jasmine has more than 4 years, it is useful to ventilate the heart of the subject and shorten the stems that start from the base. They are shortened by about 25% of their length or a little more without ever exceeding 30%. The goal is to promote the growth of young stems of the shrub. We take the opportunity to eliminate very old branches, those that are damaged as well as dead wood of course.

Pruning a jasmine is the key to enjoying a blooming profusely year after year and for limit exuberance of the shrub because if we are not careful it can become invasive because of its incredible vigor, especially if it benefits from the best living conditions. But we emphasize that the pruning of jasmine should in any case be moderate.
