Hey guys, this is my cactus Fred. I'm a pretty new cactus owner and I forgot that growing season started and for a couple months so have only just started watering him regularly. I've noticed that recently his spikes have gone hard and got a red/brown-ish tint to them, especially at the top. Is this because he's dried out, been in the sun too much or could it be rot?

Please help!

I think the color is due to new growth. All my cacti have more intense spine colors in the point of growth area when they begin new active growth.

On an aside here, I don't think your plant is getting enough sunlight. I think the growth is stretching too much. I'm not sure what your cactus is exactly, but I think the top growth should match the lower part of the barrel better than the photo indicates. That may be last seasons growth I'm seeing. How many hours of direct sun does it get?

You have this one type of rebutia pygmaea, under the name Rebutia torquata

Its somewhat common in cultivation, though really obscure.
I used to think they were a type of echinocereus.
Anyway, as a plant they are weird.
If the lighting is too dark, they etiolate easily.
If its too bright, they sunburn just as easily.
They have a "golden zone" which involves very bright, indirect light where they grow.
Water it less, and keep the soil draining and coarse.
Never had one bloom, nor had one live as long as my current one.

Thank you both! I've been struggling with getting the right light as I've just moved home from uni and he was thriving in the light in my flat there. I did notice he was stretching as well and leaning towards the sun, I've moved him somewhere with bright indirect light to see how he does Smiling
