How to Grow Crossvine

Overview

Crossvines are perennial vines that bloom from mid-March until mid-June. They are aggressive vines that can grow up to twenty feet long each. Their foliage is green during most of the year, however they are a reddish purple in the winter. Crossvines can grow in USDA Hardiness Zones 5 to 9.

Step 1

Select a site to plant your crossvines. They need full sun or partial shade. Along a stone wall, fence, railings and trellis are ideal places for crossvines to thrive.

Step 2

Add organic matter to your soil, if necessary. Crossvines need well draining, rich soil. Till your soil about 8 inches deep and add several inches of the organic matter, such as peat moss or compost.

Step 3

Dig a hole a deep as the crossvine container, but two times as wide. Set your plant in the hole and back fill with soil. Pat it down to remove any air pockets.

Step 4

Space multiple crossvines 10 to 20 feet apart. They will grow to fill in the gaps over the next few seasons.

Step 5

Fertilize crossvines twice a year. In late winter, use a fertilizer labeled 5-10-5 and in mid-summer, use a slow releasing fertilizer labeled 12-6-6. Always follow manufacturer directions for dosing as each brand of fertilizer has different potencies and release rates.

Step 6

Prune cross vines, if desired. Crossvines will spread quickly and soon get out of control if left on its own. After the flowering season, just pull the vines with your hand and use clippers to thin them out.
