Troubleshooting
Crimean Linden problems — and how to fix them
Crimean Linden (Tilia euchlora) 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.
Low aphid pressure (but still possible)
More resistant to linden aphid than T. × europaea or T. platyphyllos, but not entirely immune. Inspect undersides of leaves in spring; wash off colonies early with water before they establish.
Poor autumn colour
Foliage turns a dull yellow-green in autumn rather than rich gold. This is a characteristic of the species rather than a cultural problem; select position where summer form and flower are the primary features.
Witch's broom
Dense clusters of distorted twiggy growth can appear on older specimens, caused by eriophyid mites or phytoplasma. Prune out affected growth during dormancy to improve tree aesthetics.
