Wisteria plants are large, bush-like plants that produce small, light purple flowers. The flowers grow in triangular bunches, similar to how grapes grow. The plant starts out small, but can quickly grow to several feet in length. When planted in a basket, wisteria will eventually flow over the edges of the basket, similar to a creeping vine. Pruning the wisteria each year will keep it contained inside the basket. Plant wisteria in hanging baskets or in large baskets placed on a floor or table. Keep the plant in a sunny location for maximum bloom and growth.
Floral plastic (used to line pots)
Water retaining gel
Other plants (optional)
Line the basket with floral plastic if it is made of wood or natural fibers. This will prevent the basket from rotting when you water the plant. You do not have to use a liner with plastic or clay baskets.
Mix potting soil with water-retaining gel capsules and controlled-release fertilizer to create a compost for the basket. Use a ratio of four or five parts soil to ½ part gel and ½ part fertilizer. Add water to the mixture until the soil is damp, but not soaking. Place a three-inch compost layer in the bottom of the basket. Fill the rest of the basket with potting soil. Remove any grass roots from the soil.
Dig a small hole in the center of the soil. Place the wisteria plant in the hole. Pack the soil around the roots gently, but firmly to anchor the plants. If the basket or pot is large, you can place several wisteria plants in the same basket.
Cover the soil with a one-inch layer of mulch. Make sure no partof the plant is trapped under the mulch or else it will die.
Place the basket outdoors in a sunny location for best growing results. Water the plant once or twice a week, depending on the dryness of your area. Some areas may require watering three or more times a week to prevent the plants from dying. Trim the stalks back to six inches after flowers die to encourage flower growth the following year.
Fertilize the plants once a year in the spring with all purpose fertilizer. Add more soil to the basket each year to prevent exposed roots. Apply an appropriate insecticie to prevent insects from eating the plants.
Try adding other plants around the wisteria basket for a variety of blooms. Choose plants that bloom at different times of the year or day than the wisteria plant so that you always have cheery blossoms in the basket.
