Troubleshooting
Greenspire Linden problems — and how to fix them
Greenspire Linden (Tilia cordata 'Greenspire') 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 honeydew
Lime aphids (Eucallipterus tiliae) can build up in large colonies beneath the canopy in summer, excreting sticky honeydew that coats surfaces below. In most cases, natural predators (ladybirds, lacewings) control populations without intervention. Avoid planting over parked cars or outdoor furniture. Apply insecticidal soap for severe infestations on young trees.
Japanese beetle feeding (North America)
Tilia species are highly susceptible to Japanese beetle (Popillia japonica) skeletonisation of leaves. In heavily affected regions, consider neem-oil or pyrethrin applications in midsummer. Avoid Japanese beetle traps near the tree — they attract more beetles than they catch.
Basal sprouts and suckers
Like many grafted or heavily pruned lindens, 'Greenspire' can produce basal shoots from below the graft union or from surface roots. Remove promptly by cutting flush at the base — do not leave stubs, which stimulate more vigorous regrowth. Keep the root zone mulched to reduce sucker frequency.
