People are asking how to start the pups. For starting small pineapple pla ts I use a 1 gallon pot with cactus mix. I use EB stone cactus mix that has pumice pine mulch, and sand in it. Use it for all my plants. It drains super well. I add a little organic eb stone avocado citrus 7-3-3 into it and put them in 1 gallon pots. Then leave them in medium to full sun for several months, it can take up to a year to outgrow that size pot. Then move into 5 to 7gal pots with the same mix.
That's how I do it, there's probably a million ways to do it. They like well drained soil and take a while to get started then they go fast. I usually water once a month with fish emulsion or fertilize with a little well rounded fertilizer with nitrogen. Then when they flower switch to a higher potassium fert.
