Troubleshooting
Navel Orange Washington problems — and how to fix them
Navel Orange Washington (Citrus sinensis 'Washington') 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.
Fruit drop
A normal 'June drop' thins excess fruit, but heavy drop also follows drought stress, cold draughts or feeding lapses; keep conditions steady.
Aphids and scale
Soft new growth attracts aphids, and scale leaves sticky honeydew and sooty mould; treat with horticultural oil and improve airflow.
Rind splitting
Irregular watering late in the season splits the thin navel rind; maintain consistent soil moisture as fruit swells.
Nutrient chlorosis
Container plants often show magnesium or iron deficiency as yellowing leaves; correct with a citrus feed and check that soil pH has not drifted too high.
