How to Care for a Trellis Mandevilla
The mandevilla vine (Mandevilla sanderi) grows best when trellised within the garden and not in a container. The vines quickly grow 8 feet high with twining stems. The sheer size and weight of the large flowering vine requires a sturdy trellis, a fenceline or other structure to offer support. The vine produces trumpet-shaped flowers in shades of pink, red, yellow and white from spring until fall. Each flower measures up to 4 inches in length and 2 to 3 inches in width. The vine sports deep, dark evergreen foliage. It grows best in U.S. Department of Agriculture Hardiness Zones 10 to 11.

Choose a planting location that offers full sunlight for best flowering. The soil needs to be well-draining because the mandevilla will not tolerate an overly wet root system.
Dig a hole twice as large as the vine's root ball. Mix ample compost, aged manure or peat moss into the soil until it feels crumbly to the touch.
Place the vine into the hole. Plant the vine at the same level in the soil that it was in the nursery container. Tamp the soil down around the vine's root system.

Place the vines of the mandevilla against the trellis, fence line or other climbing structure. Loosely tie the vines with cotton rope until the vine learns to climb the structure. Remove the cotton rope once it is climbing the structure.
Apply 3 to 4 inches of mulch around the base of the vine. Use bark chips or leaf debris.
Water the mandevilla vine thoroughly. Keep the soil moist but not waterlogged.

Fertilize monthly using a 15-30-15 general purpose fertilizer. Follow the directions on the fertilizer label for application instructions. Water the fertilizer into the surrounding soil thoroughly.
Prune the mandevilla vine in the spring. Remove a few main shoots to encourage new growth. Prune the shoots to the ground and discard.
