Likely causes
Verticillium Wilt
Most likelyHow to tell: You will see sudden wilting of individual branches, often starting on one side of the plant. If you cut a small branch, you might see dark streaks in the wood.
What to do: There is no cure for this soilborne fungus. Prune out the affected branches well below the damage and disinfect your tools with bleach between cuts to prevent spreading.
Underwatering
PossibleHow to tell: The leaves look limp and dry, and the soil feels bone dry several inches down. This happens if the plant has not been watered during a hot, dry spell.
What to do: Give the plant a deep, slow soak at the base. Ensure you are watering every 7 to 14 days during the growing season.

When to worry
If the wilting is caused by Verticillium wilt, it can be fatal to the entire plant. If it is just dry soil, the plant should perk up within a few hours of watering.
Stopping it coming back
Avoid planting in soil where other plants have previously died from wilt. Keep the plant healthy with proper watering to help it resist stress.
