Plants. Lime makes soils less acidic and more alkaline. Most plants grow best in slightly acidic soil. By adding lime to the soil, you can kill a variety of pest plants. Fewer nutrients become available to the unwanted plants as the soil becomes less acidic.
Select a well-draining site in full sun for your wisteria. These plants require at least six hours of direct sunlight each day. They prefer moist locations that don't dry out excessively, but won't tolerate wet feet. Multiple plants will need at least 10 to 15 feet of space between them.
It's best to grow wisteria away from buildings and trees, and instead on a trellis or trained as a single-stemmed tree standard, because the vigorous vines can cause damage otherwise. If you set up a trellis/arbor, make sure it is extra sturdy for these heavy vines.t is best to prune wisteria right after it has flowered in mid-summer so that you don't prune off future flowering buds and lose next year's flowering display. You can prune the wisteria for structure when it's dormant in the winter months as you will be able to see the branches better.
