Hello,

I have had these cacti now for a number of years but am now starting to notice some problems with how they are looking. Is this disease or age? And If disease what do I do.

If it is feeling firm, nothing mushy, I'd say it is just corking, their natural aging.

Are your containers with drainage holes?

I'm not sure about the second plant, but the first one looks like it's probably just been in the same pot too long... that cactus can grow much larger, into a sort of shrub, with several levels of pads. Just be really careful if you do choose to move it up a size because those brown spines (technically they are called glochids) can be quite dangerous.

The top one has drainage holes. I have recently sprayed it down as it was previously in a damp house without much light and it seemed to be covered in white which I thought might be scale or mould. The second is in a pot with no drainage holes so I will move it into a bigger one this weekend as since I have moved within the last month it's grown 3 new pads. Thank you for the replies

Hello tabi09, when you repot the 2nd one, check the condition of the roots, if there are still roots. Also try not to use too big a container, it will not like sitting in a very big container where moisture holds far too long below soil line. Consider too the type of container you will use, if it is a glazed container, remember that it will hold moisture longer, so you will have to adjust very well your watering, got to allow the media to dry out. Try to make your media grittier too, if you can, mix in more pumice or perlite to it.
