WHY DOES THIS HAPPEN?

There can be a number of different reasons why grey or black dry spots may appear on your plant. These include: the plant being sensitive to lime, overwatering and/or poor drainage, dusty leaves, fungus, or underwatering.

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. Following Planta's watering schedule and always checking the soil dryness before watering can help to prevent this.

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.

Regular misting/cleaning can help prevent dusty leaves from becoming a problem and causing dry spots. If your plant requires this then Planta will let you know, as it is not necessary for all types of plants.
