My cactus has brown spots on leaves. What do I do?
I need some help here.
I moved into a new rented apartment a few months ago and there was a small cactus plant left by the previous tenant.
I'm no gardener and hadn't much interest in gardening, but I felt sorry for the plant and decided to water it and prune it.
It did extremely well and grew for a number of months until the last 4-6 weeks. some of it's leaves are turning brown and are dropping off. The plant is still growing fast though.
I'm in distress for the plant now! I don't know what to do!
The plant is usually placed by the window-sill where it can get the most sunlight. Is that wrong? should it have more shade? I have no clue!
I know I'm doing a whole lot of things wrong here but I have no clue where to start!... I don't even know what type of cactus I have!
Could someone please help. This plant has become a friend to me!
Here are a few pics of it.
I'd be truly grateful for any advice!
