Jasmines grow best in full sun, although some varieties will tolerate part-shade. Indoors supplement the natural light with a grow light. Plant jasmine vines in soil that is rich in organic matter, well-draining and moist. Soil that drains well is especially important if you are growing your jasmine vine outdoors in a United States Department Of Agricultural hardiness zone where the plant is marginally hardy such as hardiness zones 5 and 6. The majority of jasmines are hardy in USDA hardiness zones 7 though 11.
Container grown plants are best transplanted in the fall right before you take the plants indoors for the winter. Jasmine vines that are planted in the ground are best planted in the spring as soon as the ground and air temperature is 70 degrees Fahrenheit and all danger of frost has passed. This gives the plant several months to establish its root system before winter. Insert a soil thermometer into the ground and let it sit for 5 minutes to determine what the actual soil temperature is.
Dig a hole that is three times the size of the root system. Amend the soil with compost or other organic matter to improve drainage and increase soil fertility. Dig the jasmine vine up or remove it from the pot once the new planting hole is prepared. Jasmine vines that are being dug from the ground benefit from having their roots submerged in a bucket of water for 30 minutes before being replanted. This gives the roots a chance to take up enough water to sustain the plants foliage and prevent wilting. Backfill the hole with the amended soil until there is enough soil in the hole for the plant to set at the same depth it was previously. Set the plants root ball on top of the soil, backfill and water well.
The key to getting your jasmine vine to re-establish in its new home – whether that is a container or in the ground – is to provide adequate water. Water the plant deeply once a day for the first week. After that, water every two to three days as needed for another week. By now the jasmine vine should be sending out new roots. Keep an eye on the plant and if you see signs of wilting, water immediately, otherwise, begin watering once a week if there is not adequate rainfall. Spread a 3 inch layer of mulch or compost over the planting area to help retain soil moisture.
