Planting & Care

Plant Sky Vine in a location that receives full sun and has well-drained soil. Dig a hole twice the width of the root ball and plant at the same depth as the container. Backfill with soil enriched with compost or organic matter and water thoroughly to settle the roots. Provide a trellis, arbor, or fence for the vine to climb. Space plants about five feet apart when covering fences or large structures. Water regularly while allowing the soil to dry slightly between watering. Fertilize in spring and fall with a balanced flowering plant fertilizer. Prune lightly in early spring to remove any dead or tangled growth and encourage vigorous new vines.
