The increased demand of this tree species is credited to its extreme hardiness (drought tolerance and disease resistance), adaptability to different types of soil, and most importantly, breathtakingly attractive blooms in shades of pink, purple and blue. Among the various cultivars, the Chinese variety (Wisteria sinensis) is most commonly planted.
Grafted wisteria grows and develops very fast, while blooming occurs within 4 years of plantation. Whichever propagation mode you choose, maintaining the tree is so simple that in some areas it is considered an invading plant species
For planting the sapling, remove it gently from the packaging and expose it to the air. Then soak its base in water for 3-4 hours, prior to planting it in the soil. This allows re-hydration of the tree and promotes quick growth of new roots.
Growing the Tree
Dig the soil and make a plantation hole large and deep to place the root ball without damaging the roots. The root crown should lie one inch below the top soil layer after planting. Place the tree and fill the hole with soil, taking care that you do not disturb the fragile roots. Lightly press the soil around the plant, thereby making it firm. Water deeply.
As far as supplementation of fertilizers is concerned, minimal addition is sufficient to ensure timely flowering. Never supply a heavy dose of chemical additives, or the blooming will be hampered. If required, stake the tree and train it to grow in an upright manner.
Pruning this tree is imperative to promote timely flowering and production of maximum blooms. Yearly removal of the twigs will help maintain the crown in a proper shape. Other benefits of regular pruning are improving light tapping, increasing tree vigor, and controlling disease and pest infestations (to some extent).
