Wisteria Pests A variety of pests nibble at wisteria leaves, but only the wisteria borer has been observed giving established plants any real problems. These tiny beetles cut perfectly round holes into the woody parts of the vine, where they may spend a significant portion Read more
In Chinese wisteria, all the flowers in a cluster bloom at the same time. Japanese wisteria flowers are “indeterminate,” which means the lower flowers in the cluster open first, and blooming progresses along the cluster from base to tip.
So how do you know if your wisteria with no leaves is simply slow to start (dormant) or actually dying? Check for stem flexibility first. If the plant bends easily, it's ok. Dead plant stems will snap and break off.
Plant wisterias in full sun or partial shade, but make sure the vines receive at least six hours of direct sun daily to encourage good flower development. Also choose a sheltered planting location if you live in a colder climate, since the flower buds can Read more
Wisteria enjoy neutral to slightly acidic soil. Overly boggy, soggy soil is not a condition that a wisteria will put up with and that excess moisture will manifest in limp, yellowing leaves that will start to fall off the plant. Check your drainage and stop Read more
Pythium fungi shoulder the blame for most cases of root rot in wisterias. But the fungi only feast on the roots of the wisterias if the roots sit in water due to poor drainage or excessive watering. Moist soils throughout the country contain the fungi.
Crown and Root Problems Crown galls, cankers, root rots and graft failures may result in the total collapse of your plant. These conditions usually cause plants to slowly fail, wilting all or part of the canopy, as the sick plant parts have increasingly less access Read more
A wisteria root system digs deep and spreads wide in order to anchor the huge vine. Experts recommend that if you locate a wisteria near a structure or walkway, you should insert a corrugated panel some 6 feet (1.8 m.) long and several feet (1 Read more

Water them every two to three days when rain doesn't happen – or whenever the top few inches of soil is dry when you insert your index finger. Annuals in pots and baskets likely will need water every day. At least check them daily. Soak Read more
Wisteria produces its flowers on new growth from spurs off the main shoots. Prune all this year's new shoots back to a spur leaving no more than about about 6 inches of growth. In the process the whole plant can be tidied, trained and tied Read more
Wisterias can be grown in containers but they will never be as successful as those planted in the garden. Ideally, only plant wisteria in a pot if you're training the plant as a standard tree. Choose the largest container you can find and use a Read more
“Wisteria is a deciduous twining climber native to China, Japan and eastern United States.” (Royal Horticultural Society, UK) The difference is in the training and pruning. Wisteria can grow to 30′ and can be quite aggressive so the tree form is a good solution for Read more
Dead plant stems will snap and break off. Next, scrape off a little bark or break a small piece off. Green indicates health. Unfortunately, if it's brown and dried out, the plant is most likely dead.
Other: All parts of the plant are poisonous, but it is most often the seeds or seed pods that are ingested. Symptoms: Symptoms can include burning mouth, nausea, abdominal pain, vomiting and diarrhoea, sometimes followed by collapse. Warning: Seek urgent medical attention for all ingestions.
Use organic insecticides whenever possible, such as neem oil or other horticultural oils. Trunk sprays for borers only work during the insect's egg-laying period. Sprays will not kill borers once they are inside the tree.
Aphids and Mealybugs Aphids congregate on the underside of leaves and have green, yellow, red, brown or black bodies with a wooly or waxy appearance. Female mealybugs appear as small pieces of cotton on leaves and stems of the wisteria, but winged male mealybugs are Read more
Once the wisteria has reached the desired height, pinch off or cut the main vine tip to stunt its growth. Even trained wisteria vines require regular pruning; otherwise, wisteria will quickly take over everything in its path.
Wisteria is fully hardy, although the emerging flowers (racemes) can be damaged by frost (see below) which means a sheltered spot is best. Wisteria are usually easy to establish, fast growing and need a lot of space, and time.

Wisteria Leaf Curl: Reasons Why Wisteria Leaves Are Curling This common problem may seem overwhelming, but it's a pretty simple situation. Curled wisteria leaves are commonly caused by sap-sucking pests or a lack of fertilizer in the soil — both are easy to remedy.
Sharp spring frosts can cause flower buds to drop before opening, or result in distorted flowers. Other possible causes for poor flowering are too much shade, or inadequate levels of potassium.
Wisteria needs a sunny wall. Don't waste your time giving it a wall facing north or east. South and west are the more favoured aspects, where the wood will ripen most effectively.
Wisteria vines require a very sturdy structure to climb on, such as a metal or wooden trellis or pergola. Mature plants have been known to get so heavy that they break their supports, so plan with care and build your structure with hefty materials.
Warning: Wisteria flowers are edible, the rest of the plant is poisonous. A note of warning: even though wisteria flowers are edible, wisteria pods and the rest of the plant are in fact poisonous.
TOP TIP – Wisteria are hungry plants, so mulch with well-rotted horse manure spring and autumn. This will slowly release nutrients into the soil and help ensure you have a fabulous flower display.
Poor Pruning Plants that do not receive sufficient light have fewer leaves and slower growth. They will also be paler in color with leggy growth once it does emerge. If pruning has caused a delay, don't worry too much as sprouting will eventually occur.
