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.
Both Japanese and Chinese wisteria need pruning, although the Chinese vine grows a bit slower and produces a smaller plant. There are at least two types of pruning necessary to maintain a wisteria plant: pruning to control growth and pruning to encourage flowering. If the plant is totally out of control, it can be cut back almost to the ground to rejuvenate it but it will take several years for flowers to reappear.
