In Newhall, I could easily root things using Mel Hulse's "Rose Rustler's Toolkit" method. Not here! EVERYTHING I tried, using every method I tried, no matter how I tweaked them, rotted. Too arid to leave them uncovered. Too humid to cover them. This makes use of the optimums in the perfect time of year. Planting callused cuttings deeply in the soil so the soil keeps them damp, cool and dark, while leaving only the top inch or two uncovered works perfectly. As long as the cuttings are as dormant as possible so they contain enough stored nutrients to feed themselves until they form leaves to take over that function.
