Likely causes
Drought Stress
Most likelyHow to tell: The leaves look wilted and feel dry or brittle to the touch. This happens quickly during hot, dry spells.
What to do: Give the plant a deep, thorough watering until the soil is moist several inches down. Mulch around the base to help the soil hold onto moisture longer.
Root Damage
PossibleHow to tell: The plant wilts even when the soil is moist. You might notice the plant leaning or pulling out of the ground easily.
What to do: Check for pests or rot in the root zone. If the roots are mushy, you must improve drainage immediately.
