I have three Echinocactus grusonii growing in a pot together (apologies for typing error in the thread title). They're roughly 2" in diameter each. I've had them for a few years now. They were recently due for a repot, as they were incredibly crowded and it was getting difficult to get water in the pot, and roots were starting to peek out the bottom of the pot.
Unfortunately, I wasn't able to find the type of pot I was looking for (something wide and shallow), so I made the decision to move them into an unglazed terracotta pot with more width. I wasn't super happy with the particular pot, as it's too tall for the plants, and might run the risk of retaining too much water.
I finally came across a new pot, the same width as the one I moved them to, but half the height. I'd ideally like to move them into this one as it's a more appropriate size for them.
My question is, the cactuses were transferred to the new pot a few weeks ago. I think it was 4-5 weeks roughly? Would it be okay to repot them again into the shorter pot? Or is this going to be too stressful on them? I've never tried to repot after another repot, so I've been nervous to do it. In hindsight, I probably should have waited a bit longer to move them, but they were admittedly overdue for an upgrade and I wasn't expecting to find something more suitable any time soon.
I can take pictures of the plants and pots if needed.
Suggestions are much appreciated.
