Planting Advice for Wisteria floribunda Black Dragon Tree
Our pot grown Double Purple Wisteria can be planted at any time of the year. Start by removing all weeds and grass within a metre of your intended planting hole, which is ideally next to something the Wisteria can climb up. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, especially if you have poor soil, we advise sprinkling root grow in the hole.
Take the pot off and gently loosen the roots, then place into the planting hole. Mix 50% of the original soil with 50% compost, then fill in the hole and firm around gently, making sure not to bank the soil up around the collar. For further information, visit our help and advice section.
Aftercare of Wisteria floribunda Black Dragon Trees
If you’re planting in spring, summer or dry weather, water well and regularly for the first few months. Make sure to keep an eye on young Double Purple Wisteria and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits, suitable for a variety of planting schemes.
Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons.
Pruning Advice for Wisteria floribunda Black Dragon
Wisteria plants have a reputation for being high maintenance when it comes to pruning, but this is not the case! When pruned at the correct times, Wisteria is easy to control and a pleasure for everybody.
Wisteria floribunda Violacea Plena needs to be pruned twice a year. - in July or August and then again in January or February. In summer, after flowering, prune the green, whippy shoots from the previous year’s growth. This encourages flower production and helps to control the overall size. In January, remove up to half of the previous year’s growth, leaving just a few buds on each stem.
