Likely causes
Excess Nitrogen
Most likelyHow to tell: The vine is growing very fast with lots of lush green leaves but zero buds.
What to do: Stop using high nitrogen fertilizers immediately. Switch to a fertilizer higher in phosphorus and potassium to encourage flower production.
Insufficient Sunlight
Most likelyHow to tell: The plant is in a shady spot and looks sparse or stretched out.
What to do: Move the plant or prune back surrounding trees to ensure it gets at least 6 hours of direct sun daily. Wisteria needs full sun to set flower buds.
Improper Pruning
PossibleHow to tell: You are pruning the plant heavily in spring or autumn, removing the buds before they open.
What to do: Prune your wisteria twice a year. Cut back long green shoots in mid summer and shorten the side shoots to 2 or 3 buds in late winter.
