Wisteria FAQ

Q. What is a wisteria?
A. Wisterias are a classic deciduous climbing plant, perfect for covering walls, arches and pergolas as the heavy flowers create a wonderful drooping shape. The blossoms add a pop of colour to your garden with beautiful blooms ranging in colours from purple to pink, and white. Native to Japan they signify long life and immortality as they can live up to 100 years.

Q. How do I grow a wisteria?
A. These fast-growing plants with the right care will keep on growing and growing. Attach to a trellis or around an archway to control the shape of your wisteria, and create a beautiful feature in your garden. Plant in a sunny spot for vibrant flowers come growing season. Plant in either spring or autumn.

Q. What type of soil do they need?
A. Well-drained and fertile soil is best. Wisterias will not handle being grown in a pot, they need as much room to grow as they can get.

Q. Are they hardy?
A. Wisterias are notoriously hardy and left to their own devices will invade any nook or cranny it can find. Give your plant a south or west facing aspect for the right amount of sun exposure.

Q. Where do I plant a wisteria?
A. As they can be quite invasive growers, be sure to not plant them too near any other plants as they may take over. Be careful planting close to your home as a happy wisteria will cover as much room as it wants. Careful pruning takes care of this.

Q. How much pruning does my wisteria require?
A. To keep your plant flowering and growing in the shape you desire prune in late winter, cut back about half of the last year's blossoms as new ones will grow on fresh wood. Prune new growth in late summer time to encourage more flowers.

Q. Do I need to feed my wisteria?
A. Spring time is when to give your wisteria an extra boost to grow those magnificent blooms. Rose fertiliser is readily available and perfect for promoting the growth of flowers.

Q. My wisteria isn't flowering, what do I do?
A. A common cause of this could be too much nitrogen in the soil, this will cause heavy foliage but little flowering. Make sure the soil is well-balanced by adding a phosphate fertiliser to the soil. A full sun aspect will also encourage lots of flower growth so make sure it is not too shaded.
