What are the grey and black dry spots?

The presence of gray or black spots on your plant's leaves could signal various issues, ranging from diseases to potential watering problems.

Black spot fungus

Common causes

There could be a number of different causes. The plant being sensitive to lime, overwatering and/or poor drainage, dusty leaves, fungus, or underwatering.

What to think about

Regular misting/cleaning can help prevent dusty leaves from becoming a problem and causing dry spots.

Overwatering or having poor drainage weakens plants and often makes them susceptible to fungal problems. Make sure to check on each plant’s specific water needs - some plants prefer to dry out between waterings, whereas others prefer to maintain a certain level of moisture. In any case, it’s never a good idea to leave plants completely soaked and waterlogged for prolonged periods of time.

If you believe that lime sensitivity may be the problem, it may be worth investing in a water purifier to avoid watering your plant with alkaline water. You can also use rainwater if you have access to it. Species that are especially sensitive to alkalinity should be planted in acidic or ericaceous soil mixes.
