What is the best fertilizer for wisteria?
Wisterias usually don’t need fertilizing. If you want to fertilize, a 0-10-0 granular product dug in around the plants in spring is a good choice. Prune your wisteria twice a year to keep it in check and make sure you get lots of magnificent flowers each spring. Remember that sunlight needs to reach the wood at the base of younger plants in order for it to ripen and produce flower buds.Wisteria is a hungry plant. Feed monthly with a high potash fertiliser during the growing season, to encourage more flowers to bloom. Water and feed pot-grown wisterias weekly. In autumn, mulch with organic matter such as well-rotted horse manure or home-made compost.Wisteria can grow up to 10 feet a year, especially once it’s established in the proper environment. It performs best in deep, moist, but well-drained soils that are neutral to slightly alkaline.How to summer prune wisteria. After flowering, in July or August, cut back the whippy green shoots of the current year’s growth to five or six leaves. This controls the size of the wisteria, preventing it from growing into guttering and windows, and encourages it to form flower buds rather than green growth.
What plants go well with wisteria?
Perennials To Plant With Wisteria Other less aggressive perennial vines are great partners for a Wisteria growing in a naturalized area of the garden. Choose from clematis, akebia, and honeysuckle, which all bloom after Wisteria and add lovely color and scent for the rest of the summer. Blooming their heart out in late spring to early summer, both these climbing vines provide interest after flowering is over, thanks to the seedheads left by the passing clematis flowers and the long velvety, bean-like pods left by the wisteria. Clematis and Wisteria can be perfect companions.
What is the best thing to feed wisteria?
Feeding wisteria plants every spring will give the best results. You can use Miracle-Gro Growmore Garden Plant Food or Miracle-Gro® Fish, Blood & Bone All Purpose Plant Food, but a rose or flowering shrub feed will generally give better results. In very well-drained soil, also feed with sulphate of potash in summer. Using a high potash feed like liquid tomato feed is beneficial for wisteria as it encourages more prolific blooming. Timing: The best time to start feeding your wisteria with a high potash feed is when you first notice the flower buds forming.If you’re growing your wisteria in a large container – which you can do with less vigorous varieties – then a liquid tomato feed throughout the growing season works perfectly.Once established, wisteria should only need supplementary water during dry periods. You may wish to apply a high potash feed during the spring to encourage flower production, but don’t overdo it because overfeeding can result in more foliage and fewer flowers.If you’d like to grow your wisteria in a container, you’ll need a large container of at least 45cm (18in) filled potting compost such as John Innes No. It will take more effort to grow than if planting in the ground as wisteria are very hungry plants, so they’ll need more feeding.
What is one of the biggest problems with having wisteria growing nearby?
Displacement of native vegetation: Chinese wisteria’s aggressive growth and ability to thrive in various conditions make it difficult for native plants to compete. Ecological damage: By displacing native vegetation and altering forest structure, wisteria can disrupt ecosystems and negatively impact wildlife. Wisteria has been around a long time, with 7 million year old fossils of Wisteria sinensis, or Chinese wisteria, found in China. Plants live an average of 50 years but can survive much longer.Asian wisteria species are also very long-lived, up to 50 years. With 10 feet (3 m) of growth per year, you can have a full-size vine within just a few years.Chinese wisteria grows so rapidly that it covers plants, shading out others and even killing trees. Chinese wisteria (Wisteria sinensis) is able to damage local ecosystems because of its rampant growth and ability to thrive in a number of different conditions.Wisteria can climb up tall trees and will continue to grow in the tree canopy where it can shade out smaller trees and plants below. Additionally, individual wisteria plants can live for more than 50 years; wisteria’s longevity only increases its ability to invade an area and choke out native plants.
Do wisterias like full sun or shade?
Wisterias do best in well-drained, fertile soil, in full sun. They are native to China, Japan and eastern United States and, of the ten species, the three most commonly grown are Wisteria floribunda (Japanese wisteria), Wisteria sinensis (Chinese wisteria) and Wisteria brachybotrys (silky wisteria). Wisteria planted in full sun will bloom more reliably than plants located in part shade. Make sure the upper part of the plant receives at least six hours of daily sun exposure.When does wisteria bloom? Most wisteria bloom in mid to late spring. Some varieties, like ‘Blue Moon’, may rebloom in summer.Wisteria flowers best in full sun, with few if any flowers forming in deep shade.Wisteria is not an indoor species. It thrives best outdoors in full sun and experiences natural seasonal cycles. If grown indoors, it will likely weaken and fail to flower.Prefer full sun. Established vines grow and flower in partial shade. Chinese wisteria is more tolerant of shade. Tolerates a wide range of soil conditions.
