Possible causes: overwatering, poor drainage, a nutrient shortage or too little light. Check the soil moisture first, let the top layer dry before watering again, and move the plant to suitable light. Feed lightly during the growing season.
Older leaves yellowing is often normal ageing, but it can also mean overwatering or a nitrogen shortage. Remove the dead leaves, ease off watering and apply a balanced feed.
New leaves turning yellow usually points to a nutrient shortage (often iron), very bright direct light or cold draughts. Check your feeding routine and move the plant out of harsh sun.
A uniformly pale plant often means too much light, a nutrient shortage or root problems. Check the roots, repot into fresh mix if they are damaged, and adjust the light.
Root rot comes from soggy, airless soil. Take the plant out, trim mushy brown roots, repot into fresh well-draining mix, and water only when the top layer dries. Improve drainage and empty the saucer.
Inspect the undersides of leaves and the new growth. Isolate the plant, wipe off the insects with a damp cloth, then treat with insecticidal soap or neem oil, repeating weekly until clear.
Fine webbing and speckled, dusty-looking leaves suggest spider mites. Raise the humidity, rinse the leaves, and treat with insecticidal soap or neem oil every few days.
White cottony clumps in the leaf joints are mealybugs. Remove them with a cotton swab dipped in rubbing alcohol and repeat weekly; check nearby plants too.
Sticky residue or tiny flying insects point to aphids or whitefly. Wash the leaves, remove badly infested shoots and treat with insecticidal soap.
A white powdery coating is powdery mildew, which thrives in poor air flow and humid, still conditions. Improve ventilation, remove affected leaves, keep the foliage dry and use a suitable fungicide if needed.
Crispy brown tips usually mean low humidity, inconsistent watering or a build-up of salts in the soil. Water more evenly, raise the humidity, and flush the soil occasionally.
Brown tips alone often signal low humidity or fluoride and chlorine in tap water. Use filtered water, raise the humidity and trim the dead tips with clean scissors.
Brown patches in the middle of leaves can indicate sun scorch, fungal spots or cold damage. Remove affected leaves, keep the foliage dry and adjust the light and temperature.
Wilting can mean too little water, too much water or root damage. Feel the soil before acting, and check that the pot drains freely.
If the soil is wet and the plant still wilts, the roots may be drowning. Stop watering, improve drainage and let the soil dry out; check for rot.
If the soil is dry, water thoroughly until it runs out of the drainage holes, then water again when the top layer dries.
Sudden leaf drop is usually stress: a change in light, temperature, watering or position. Keep conditions steady, avoid cold draughts and let the plant settle before changing anything else.
A plant that will not flower may be short of light, overfed with nitrogen or simply too young. Give it brighter light, switch to a bloom feed and avoid moving it while buds form.
