Core guide
Check moisture and roots
Many problems come from too much or too little water. Feel the mix and, if safe, look at the roots: healthy roots are firm and light-coloured.
Look for pests
Inspect both sides of leaves and stems. Act early and use treatments appropriate to the pest and plant.
Fix the cause
If the mix is dense and wet, repot with better aeration. Products support healthy conditions but do not cure disease.
