Keep cuttings in the shade until they have roots. Few Echeveria are going to be happy in full sun in Riverside. It gets way too hot for that. Find a place that gets 2-4 hours of morning sun, and the rest of the day in bright shade. Cuttings without roots have limited water reserves, and no way to absorb any from the ground. It will take several weeks to form roots, so put them in pots so you can limit sun exposure until they are ready for direct sun.

This is a little late but as I was going through this thread I realized that I never responded with a thank you reply and for that I apologize.

I actually did take your advise back then and they did very well inspite of my ignorance. They do prove to be very hardy plants so it's kind of hard not to appear as a green thumb expert with this type of plants.
Thanks Brad,

Greg
