The cacti have a special way of growing that differs from other plant species. They need heat and long days, and the spectrum of sunshine and brightness that comes from spring and summer. They sit there dormant in winter in most cases. As long as they get full sun and lots of heat, they should start showing new growth in the next few months as we move into spring.Interesting, thanks.

PS- I planted ten pads in sandy soil a month or so ago, and haven't seen any new growth ... should I dig them up to feed to my Darwin or just give them more time?
Give them more time.
