How to Grow and Care

Honeysuckle vines should be planted during the spring in cooler climates because their roots thrive when cool and shaded. Make sure to wait until the final frost before planting them.

When the timing is finally right, locate a spot for planting where they'll get full sun, or at the very least, partial sun exposure. Plant your honeysuckle at a soil depth of 18 inches and lay an organic fertilizer or compost over the top 3 inches.

This type of vine is sensitive to the amount of water and moisture it receives. When you first plant your honeysuckle, the plant will need a considerable amount of water to help it grow. However, by the time summer arrives your vine will be more fortified and only need small amounts of water, even during dry spells. Many people make the mistake of continuing to water the plant equally throughout these different stages, which is a definite recipe for harmful overwatering in the summer months… – See more at: 6 Mistakes to Avoid When Growing Honeysuckle Vine
