Wisteria

WhiteWisteria truly is a plant that fills any garden with joy. When you think of that perfect country garden, you imagine a large Wisteria with its purple blooms encircling the front door of the cottage of your dreams. This is why it is such a shame when this beautiful plant isn’t taken care of properly, which often ends in there being little to no flowers. This active climber is best planted between autumn and spring, and as a lover of the sun is best to be situated on south and west facing walls. Within three to four years of planting you will begin to see beautiful purple or white flowers depending on the variety, between May & June. However, to get the most out of your stunning plant, pruning is key. Prune your Wisteria twice per year – in July/ August and January/February. Pruning of growth during the summer encourages better air circulation and greater amounts of light to reach the young growths. This provides better ripening of the wood and increases the chances of flower bud formation, resulting in better blooms. So how do you prune your wisteria? In the summer months (July/August), cut back the green shoots of that year’s growth to five or six leaves which helps to control the size of the plant. This also helps to stop any unwanted invasion of guttering etc. Then, during winter months Wisteria 'Black Dragon'(January/February) when the plant is leafless, cut the same growths back by two or three buds. Another common issue that can cause problems with the production of flowers on your wisteria, can be due to excess nitrogen. A wisteria with too much nitrogen will have plenty of foliage but very few blooms or even none at all. An easy solution to surplus nitrogen in the soil is to feed the wisteria with a phosphate fertilizer. If unsure it is always helpful to consult a professional horticulturalist who can troubleshoot any issues with your plant and recommend treatments. It’s as simple as that! Be sure to water your Wisteria during dry periods and particularly in sandy soils to give it the best care possible. Hopefully by following these simple steps you will be able to enjoy this amazing fragrant beauty for many years to come in your garden.
