Troubleshooting
Miss Kim Lilac problems — and how to fix them
Miss Kim Lilac (Syringa pubescens subsp. patula 'Miss Kim') 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.
Reduced bloom in shade
Although compact and reliable, it still needs full sun to flower well; in too much shade it blooms thinly and grows looser.
Mistimed pruning
Blooms on old wood. Any shaping should be done immediately after flowering; later cuts remove the next season's buds.
Occasional powdery mildew
More resistant than common lilac but can still show light mildew in humid, crowded conditions. Maintain airflow and full sun.
Scale and lilac borer
Susceptible, like all lilacs, to scale and stem borer. Inspect stems, prune out infested wood, and keep the shrub vigorous to limit damage.
