Gelsemium Sempervirens Care

Put on long sleeves and gloves before trimming a Carolina jessamine. The sap can irritate your skin Trim dead or dying vines -- those without leaves or with wilting leaves -- in the winter and early spring by clipping them at the base of the vine with pruning shears Cut back the vine in midsummer after the plant has finished blooming. Carolina jessamine grows quickly during the blooming season. If you need to keep it contained to a specific area, such as a fence or trellis, cut vines that are too long in midsummer. Use pruning shears to remove the vines at the base, which could be the main stem or another vine.

You can use a general purpose commercial fertilizer, but the best fertilizer for Carolina Jessamine plants is a 2 to 3 inch (5-8 cm.) layer of compost, leaf mold, or aged manure.

It will tolerate light shade, but best flowering and growth occur in full sun.
