Q.My Chinese Wisteria Blooms Fall to the Ground
Chinese wisteria blooms fall to ground as soon as vine starts blooming. It’s about 10 years old. No insect problems. It seems like the slightest breeze shatters the bloom. What a mess! Twice a day sweeping right at the back door. Covering a wooden pergola.
I would look carefully for thrips. They are hard to see and will attack the base of blossoms, causing them to fall off before they open.
Treat the plant with neem oil. That will take care of both pests and fungus and is safe for people and pets.
