Reviving a wilted hosta involves taking corrective measures to address the specific cause of wilting. First, you need to identify these underlying causes.
Insufficient watering usually leads to wilted hostas. Check the soil moisture level by digging a finger about one inch into the soil near the plant's base and see if it's dry.
Usually, a hosta needs an inch of water per week, so adjust your watering practices based on the plant's needs. Ensure that the soil is damp but not overly saturated.
If there's excessive sunlight, provide shade or relocate the plant to a spot with filtered or indirect light. Similarly, provide cover during severe weather or consider relocating.
If pests are causing the wilting, introduce organic insecticides or beneficial insects. In the case of diseases, use proper fungicides or bactericides.
Improving the soil quality is also vital for the plant's revival. Try adding organic matter like compost or peat moss to the soil to improve drainage and promote healthy roots.
