Finger Lime problems — and how to fix them
Finger Lime (Microcitrus australasica) 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.
Spider mites
Thrive on dry, dusty foliage indoors and over winter; check leaf undersides for stippling and fine webbing and raise humidity.
Citrus leaf miner
Silvery serpentine trails distort new flushes; prune affected tips and protect tender spring growth in warm climates.
Magnesium/iron chlorosis
Interveinal yellowing on older or new leaves signals nutrient lockout; correct pH and apply chelated micronutrients.
Cold damage
Frost scorches leaves and can kill stems below about -2°C; move containers under cover before the first frost.
