"A 30 year major hobby is growing and propagating suculents indoors. I live in the foothills of the Rockies at 7500' where winter temperatures can get down to -25° C. Currently I have about 250 plants (pots). One of my favorites is sansevieras. I formulate my own potting mixes. For the first time ever I've had an epidemic of wooly aphids and have lost some rare plants."
