Q: How can I get my wisteria to bloom since it has not bloomed for years? A: Although most wisteria purchased from a reputable nursery will flower, many wisterias can be very stubborn about blooming. Here are some steps that you can try, however to try and help them flower. First, prune them back heavy in June to stimulate growth. Second, you can try root pruning, by taking a shovel and making a series of cuts in the ground. Making a circle around the tree about several feet out from the main trunk, take a shovel and cut into the ground about every 12". So if the circle were a clock with the tree in the middle, make cuts at 12, 2, 4, 6, 8 and 10. By cutting the roots, you are stimulating growth, which often will encourage flowering. Third, into the cuts in the ground add super-phosphate fertilizer with a high phosphorous plant food (no nitrogen). | |
