Inland locations in Cali, is really too bone dry and hot, so once a week watering for flowering plants will not be sufficient, especially when the higher 90's to triple digits come in during late Spring all the way to summer. San Francisco side is good or coastal San Diego is good, they have the marine layer in summer, but our inland locations, is just searing heat. I have learned that now, not to expect blooms in my garden, unless I am ready to water almost everyday during the hot summer days. I get blooms with my other plants only in mid Fall, sometimes in Winter, then to early Spring..after that..only the toughest of succulents can stand our heat, even the succulents, you have to give some shade with the searing heat. Plants will just start shutting down and conserve their resources in our super hot, dry days.
