Troubleshooting
Maleberry problems — and how to fix them
Maleberry (Lyonia ligustrina) 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.
Chlorosis in alkaline soil
Yellowing foliage with green veins indicates iron or manganese deficiency caused by soil pH above 6.0. Lower soil pH with elemental sulfur and apply chelated iron. Test soil pH before planting; never site near lime-mortar walls or recently limed soil.
Legginess and poor flowering
Maleberry blooms on the previous year's wood. Pruning at the wrong time (late summer or autumn) removes next year's flower buds. Prune only immediately after flowering in early summer, removing no more than one-third of the oldest stems to encourage bushy, floriferous growth.
Root rot in compacted or poorly drained soils
Although tolerant of wet conditions, maleberry requires that water movement through the soil is not impeded by compaction. In heavy clay, amend with grit or organic matter, or plant on a gentle slope to allow drainage. Stagnant water differs from consistently moist soil.
