Tilia tomentosa 'Petiolaris' problems — and how to fix them
Tilia tomentosa 'Petiolaris' (Tilia tomentosa 'Petiolaris') 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.
Flowers narcotic to bumblebees
Silver limes are sometimes blamed for bumblebees found dazed or dead beneath them in late summer; current evidence points mainly to bees foraging on nectar-depleted flowers during dearth rather than direct toxicity. It is a recognised but largely seasonal, low-impact phenomenon.
Aphids and honeydew
Like other limes it attracts aphids that secrete sticky honeydew, encouraging sooty mould on foliage and anything beneath. Avoid planting over patios, paths or parking.
Leaf scorch in extreme heat
Despite good heat tolerance, foliage can brown at the margins in prolonged drought on shallow soil. Mulch and water young trees; mature specimens normally shrug it off.
Wide spread underestimated
The pendulous branches reach far sideways and low to the ground, needing generous space. Allow at least 10-12 m clearance and avoid tight street or boundary positions.
