Jasmine: planting, growing, caring for and pruning

The choice can be made on one of the many species of jasmine with deciduous or evergreen foliage, whose flowering, pink, white or pink, blooms according to the cases over the different seasons. Some are very fragrant, others more discreet. But whatever it is, jasmine is a climbing or bushy shrub with extremely delicately starry flowers that nicely adorns a low wall, trellis, pergola, tree trunk and even fencing, supports to which it brings a note of exoticism. Let’s find out how to plant a jasmine and then maintain it so that it thrives for many years. Let’s also take a look at the jasmine pruning method, knowing that it should never be too harsh.

Plant a jasmine

Jasmine appreciates all good garden soil as long as she stays fresh, good drained, and that she is very rich in organic fertilizer. Stony soil is especially suitable for shrubs grown in the South. Care must be taken to avoid any risk of stagnant water because this shrub hates that its roots bathe.

He likes them sunny situations good sheltered from cold winds but in areas 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, cannot withstand 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 wintering veil should be kept handy in case of exceptional cold weather.

Planting period

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

Method of planting jasmine

In the ground, it is right to :

  • Dig a sufficiently large hole, around 2 to 3 times the width of the root ball,
  • Place balls of clay 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 by tilting it slightly in order to orient 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 soil. All that remains is to take care of the trellising of the jasmine branches.

If we want to plant a jasmine in a pot, which is quite possible, you have to file a drainage layer sufficient to background and ensure that it is perforated. The container must be at least 50 cm in diameter. The ideal substrate is made up of equal parts of soil suitable for plants from the Mediterranean region or of potting soil and topsoil. Once the jasmine is installed in its tank, it is again essential to water copiously.

We then place the pot at the foot of the chosen support and all that remains is to tie the stems with ties that should not be too tight.

Take care of a jasmine

After planting a jasmine, watering should be followed so that the shrub can take root and develop. If it is planted in a pot, it is about twice a week that it is necessary to water because the substrate dries much faster under these conditions. Once the shrub is well rooted, the care to be given to it is really little.

Wintering a jasmine in a pot

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

Trellis some jasmines

When planting, care is taken to help the branches to move towards the support. Thereafter, we limit ourselves to the training of new shoots. Certain varieties of jasmine possessing tendrils, they do not need to be attached to cover a stand.

Water your jasmine

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

Fertilize the earth

From April to September, it is useful to dilute in water a low nitrogen fertilizer like that intended for roses for example, and this at a rate of twice a month. The fertilizer contributions are stopped during the plant rest period.

Repot a jasmine

Repotting of jasmine grown in a container is only necessary every 3 years, every 2 years if it develops very quickly. It can be done either before winter or in spring. This allows to offer him a bigger pot 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 particularly sensitive diseases and does not attract many pests. However, we can fear aphids and mealybug.

Mealybugs must be removed manually using a gauze previously soaked in90 ° alcohol then we spray the jasmine every 15 days for 2 months with a mixture of black knowledge and lukewarm water or soap, water and vegetable oil (rapeseed for example). These natural preparations are not aggressive for the shrub and are also perfectly suitable in case of aphid attack.

Prune a jasmine

We are content with one annual light pruning so as not to harm the jasmine. It allows the shrub to flower generously year after year but also to keep a bushy habit. Pruning jasmine is also necessary for control its growth. This therefore consists of the elimination of dead wood, dry twigs, broken or damaged stems and less vigorous branches for the benefit of the stronger ones.

A a little more substantial size without being too severe can be performed every three years approximately in order to tame the port of jasmine. Here again we wait until the end of flowering to get down to it because it is not recommended to cut back the branches until they are completely deflowered. It is recommended to make a clean cut:

  • Just above vigorous new shoots that you want to keep or above a large bud,
  • Eliminate a few extra branches,
  • To tear off the layers, that is to say the rejections which grow spontaneously at the foot of certain varieties of jasmine.

Thereafter, as soon as the jasmine will have over 4 years, it is useful to ventilate the heart of the subject and to 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 remove very old branches, those that are damaged as well as dead wood of course.

Pruning a jasmine is the key to enjoying a flowering profusely year after year and for limit exuberance shrub because if you are not careful it can become invasive because of its incredible vigor, especially if it enjoys the best living conditions. But we insist on the fact that the pruning of jasmine must in all cases be moderate.
