I bought these Opuntia cacti about a year ago, and after 2-3 months they began to wrinkle and the large one flopped over. When I bought them initially I was told to water them roughly once per week during the summer, then seldom throughout the winter.
However I wonder if the weekly water last year was too much, and it may have ruptured the cell structure of their base? Many months ago I took the large one out of its pot to check for root rot, and broke off any soggy roots, and repotted it once it had dried out.
If over-watering during last summer were to be the case, are they likely to regenerate? I have seldom watered them during the past 6 months.
Many thanks in advance!
