watering
Japanese wisteria should be watered frequently to keep the soil moderately moist. Water at least once a week during the summer months, making sure to irrigate deeply so that the soil is lightly moist. During hot summer months, the soil should also be watered at least once every 5-7 days. In the winter, reduce watering so that the soil is just barely moist. Care should be taken with overwatering, as this can cause root rot and plant disease.
sunlight
Japanese wisteria needs at least 6 hours of direct sunlight per day in order to thrive. This plant does best in full sun during the morning to mid-afternoon hours and should receive partial shade during the hottest times of the day. During the summer months, Japanese wisteria should be watered twice a week to make sure it gets enough moisture, but in winter months it only needs to be watered once a week.
pruning
Japanese wisteria (Wisteria floribunda 'Rosea') should be pruned twice a year. The first pruning should take place in late winter or early spring, while the second pruning should take place in midsummer. During the late winter/early spring pruning, selectively remove dead or damaged branches and stems. You can also prune back side shoots to 2 or 3 buds from the main stem to encourage bigger blooms. During the midsummer pruning, selectively remove any new, unwanted stems growing from the main stem and fan trunks. Be careful not to remove too much as too much pruning can reduce flower production. It is also important to thin out any overcrowded stems to promote better air circulation and light penetration throughout the plant.
