Hmmm I am puzzled with my watering regimen, not really sure what works because others thrive but others are not happy. But we are having really hot humid weather and the majority of my cacti and succulents are at the back porch where they get morning sun.
I collect rain water and those that don't get wet by rain gets the liquid gold treatment manually, when I have time. On days that we don't get rain, my desert roses get the liquid gold first but the other non-desert plants get the regular water. The indoor ones get our left over bottled water or the fresh rain water.
