Curling leaves

Signs to check

• Leaves curl upwards into a spoon shape or downwards along the central vein.
• The leaf remains firm to the touch, rather than soft as with wilting.
• Its color initially remains green, with no visible spots or yellowing.
• No insects, webs or sticky deposits are visible inside the curve.

Common causes

1. Too little water · Soil is dry and leaves are limp and drooping.
2. Excess salts · Brown leaf tips and a white crust on the soil.
3. Weather damage · Sudden damage after extreme weather such as frost, a heatwave or wind.
