I recently planted a mint plant purchased from a supermarket in some houseplant potting soil. It's been on a windowsill in the kitchen. In the last week it's acquired some sort of pest which I've tried to take photos of (below).
I have no problem throwing it away and starting again since the plant was very cheap, but I'd like this not to recur. Hence:
- Can anyone identify what this is likely to be?
- If I were to ignore it, what would be likely to happen (for example, would it go away, kill the plant, spread to other plants in my flat...)?
- What precautions should I take to avoid this happening to its replacement?
