Do you want to grow wisteria in your home or garden, but don't have enough space? Why not try growing them in pots? With attention and care, you can successfully cultivate lush wisteria in pots.
Pot Selection
When it comes to choosing a pot for planting wisteria, size does matter. Aim for a container that is at least 60cm deep and wide. The larger the pot, the healthier your wisteria will grow.
Soil and Drainage
Wisteria thrives in soil that is rich, light, and well-draining. A bed of gravel at the bottom of the pot can help with drainage. Don't forget to ensure your chosen pot has suitable perforations for this purpose.
Planting
When it's time for planting, place your wisteria in the pot at the same depth it was in its original pot. Make sure the soil is moist for optimal results.
Location and Sunlight Exposure
Your potted wisteria will benefit from six to eight hours of direct sunlight each day. Though it can tolerate slightly shaded areas, less sunlight can result in less abundant flowering. While light winds aren't an issue, you should shelter your plant from areas with stronger gusts.
Fertilization and Watering
Fertilize your potted wisteria once a month during the growth season. Use low nitrogen, high potash fertilizers in the spring to favor flowering over foliage growth. Regular watering is vital, aim to maintain moist soil without waterlogging it. Depending upon the environmental conditions, your plant may need watering every two to three days.
Pruning
Pruning is a key part of maintaining a healthy wisteria plant. Over the first two years, focus on shaping the plant by forming a group of branches at the top. Each summer, prune young shoots back to about six leaves, and in winter, prune remaining shoots back to three buds.
Re-potting
As the roots of your wisteria grow stronger over the years, re-potting may become a necessity. When doing so, you can cut back a third of the older, longer roots. Be careful though as not to damage the newer roots near the trunk.
Note: These guidelines are suitable for both the Wisteria sinensis and Wisteria floribunda varieties.
