Troubleshooting
Tilia cordata problems — and how to fix them
Tilia cordata (Tilia cordata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aphids and sticky honeydew
Limes are notorious for heavy aphid colonies that drip honeydew, blackening leaves, cars and pavements with sooty mould below the canopy. Encourage ladybirds and lacewings; avoid siting over parking or seating areas.
Basal suckers and epicormic shoots
T. cordata readily throws up shoots from the base and trunk, cluttering the clean stem. Rub off or cut these out each year to keep a tidy standard.
Leaf scorch
Leaf edges brown in hot, exposed, dry positions or windy sites. Keep young trees mulched and watered; mature trees usually recover without intervention.
Bacterial / fungal leaf spots
Cool wet springs can bring minor leaf-spotting fungi. Damage is largely cosmetic; rake and remove fallen leaves to limit overwintering inoculum.

Most tilia cordata issues are care-mismatch, not bad luck. Dial in the basics:
