My Wisteria Appears to Be Dying
Within the last 48 hours, all of the leaves on my wisteria have curled and withered as if there is a shortage of water, yet this is a water dry tolerant plant. The plant is approx 8 years old and is covering the front wall of my bungalow. This year saw the best display of flowers we have ever had on both plants. I have another wisteria on the side wall (approx 12 ft away) and this is still perfect. Could my plant have been poisioned? There is no sign of pests.
Your plant may have root gall. Check the roots for large bulbous growths.
