Wintering jasmine: What to consider when wintering in pots and in the garden

More than 200 species of the genus “Jasminum” are popular among gardeners for their beautiful fragrant flowers. Most of the flowers that belong to it are either conditionally hardy or not hardy at all. In areas with mild climates, they thrive outdoors with no problems. But even in regions with harsh winters and permafrost, jasmine can grow well as long as you take proper care of the plants. We explain how to overwinter jasmine and what to consider.

Wintering jasmine: the most important things in summary

Jasmine stay outdoors winter jasmine care

As already mentioned, there are more than 200 species of jasmine. Most of them are not winter-hardy or winter-hardy only to a certain extent. We give you an overview of the most popular varieties:

  • True jasmine belongs to winter hardiness zone 8b. This means that it can tolerate temperatures as low as – 6.7 ° Celsius.
  • Shrub jasmine also belongs to winter hardiness zone 8b and is not considered hardy in this country.
  • Arabian jasmine can do well in winter hardiness zones 9 to 11. In practice, it can rarely withstand sub-zero temperatures and survives winter outdoors only in the southern parts of Europe. In Germany, it must be overwintered.
  • Among the popular jasmine species, only winter jasmine is hardy.

Care in autumn: first cut back, then overwinter the jasmine.

The jasmine species are brought into shape after the end of the flowering period. For all non-hardy species, this ends in the fall, no later than September. The rule of thumb is: young plants are only thinned out a little – about a third of all old shoots are cut off close to the ground. Old plants are given a rejuvenation pruning. Jasmine that has gotten out of shape can also benefit from severe pruning.

Exceptional case winter jasmine: the only hardy jasmine species blooms in winter. Therefore, do not prune this climbing plant until spring. However, you can cut off yellow leaves and shoots that have become bare in the fall.

Wintering non-hardy species in a pot

Non-hardy jasmine species can not thrive the frost in winter. It’s best to plant them in a pot one to two weeks after pruning (late September to mid-October) before the first frost and move them to winter quarters.

Jasmine need a cool and bright place where they can spend the winter dormancy. Good for this purpose is the garage with a window, a garden shed or the basement (as long as it has windows and you can ventilate there). During the day, the temperature should not exceed 15 degrees, and in the evening it may even be cooler.

Jasmine overwinter care tips for autumn

It is best to give the plant time to recover after pruning. Then plant it in a sufficiently large pot and first leave the pot in the old location for a few days. Then place the pot against a house wall, protected from the wind and covered if possible. After another week, it can go to the winter quarters. First, bring it indoors only for several hours, then gradually leave it outside for longer.

If the flower is still outside in October, then you can wrap the tub with fleece and place it on a polystyrene plate.

Properly water the potted plant in autumn and winter.

The jasmine needs less water during the dormant period. So the watering can be smaller, but you should water the plant at regular intervals. To help guide you, do the finger test during the first few weeks. When the soil has dried slightly, then you can water the jasmine again.

Exceptional case: winter jasmine can stay outside.

The only species of jasmine that can spend the winter outside in this country is winter jasmine. But it, too, needs some frost protection to survive the cold season outdoors. To do this, proceed as follows:

Jasmine overwinter in the garden what to consider

  • First, give the plant a maintenance pruning, removing yellow leaves, dried and dead shoots in September.
  • Then check the plant for pests and diseases and take action if necessary.
  • Then remove weeds from the bed to avoid root competition in winter.
  • Then cover the bed with a 7 cm layer of mulch (bark mulch is best). It is best to use bark mulch or shredded autumn leaves.

Young plants are not particularly hardy and need additional frost protection . As a rule, therefore, you should plant them in a location protected from the wind. A thick layer of mulch will protect the delicate roots from ground frost and prevent irrigation water from evaporating. In addition to this, you can cover the plants with a translucent fleece during permafrost.

Water the winter jasmine only when necessary.

Winter jasmine can cope without watering. Conversely – it can tolerate waterlogging worse than drought. So when you put young plants in the ground, you can first work coarse-grained sand into the soil. This way you will improve drainage.

Winter jasmine: stop fertilizing in the fall.

Winter jasmine is fertilized with organic compost only once in March – April. The non-hardy varieties are provided with nutrients during the flowering period. However, you can stop fertilizing in the fall.
