Plant my carolina jasmine

In open soil or in pot? It's simple, if at home the temperature drops permanently below 0 ° C, it should be in pot! Do not leave it in the original pot, often made of plastic - unsightly, heated when placed in sunlight, waterproof... - Repot it in a pot much larger - in terracotta! In open soil, plant in spring in a sheltered and sunny place. It requires a rich and well-drained soil because it dreads when its roots stagnate in water: do not hesitate to bring sand for better drainage. Water copiously to facilitate rooting. Very important: provide it something to climb on, like a wall with a trellis.

Water my carolina jasmine

In pots, water often, and during winter, indoors, watering three times per month should suffice. In open soil, waterings should be moderate, except in case of intense drought.

Prune my carolina jasmine

Cut any dead, damaged or diseased shoots with pruning shears. You can also remove any shoots that cause overcrowding.

Protect my carolina jasmine

Your Carolina jasmine is non-hardy - it will not survive a frost episode! If your plant is outside and you fear a very cold period, add a thick layer of mulch, and protect it with some insulation material if you can.

Shelter my carolina jasmine

If your plant is in a pot and you have a sheltered place with a minimum temperature of 10 ° C, sufficiently bright, bring it inside for wintering, before the first frosts. Water very little during the winter. You can take it out again in May.

Put outside my carolina jasmine

Well after the last frosts, you can bring your potted potatoe vine outside in a sheltered, sunny place!

Fertilize my carolina jasmine

Apply a high-potassium fertilizer which will promote abundant flowering. Wood ashes actually make a good potassium intake! In any case reduce the amount of fertilizer at the end of the summer and stop completely in early autumn.

Repot my carolina jasmine

Repot at least every 3 years, in a larger container if necessary, and change most of the medium, bringing soil and sand for a good drainage.
