I'm trying to propagate some deciduous trees from cuttings I've taken. I have 3 different stems for each of 2 trees I've collected from (one being a red maple, the other being a mulberry). Both will loose their leafs soon, and the red maple's leafs have already turned colors. I'm in zone 5a and these cuttings were taken in the past week or so, after the first couple of frosts (nights below 32dF) but with the weather coming back to warmer autumn temperatures.
Right now I just have these cuttings sitting in cups of water as I prepare some rooting hormone from weeping willow stems, then I planned to plant the maple and mulberry stems in small pots with potting soil and water them once with the rooting hormone, then with regular water.
Do I need to do anything in particular to keep these tree cuttings growing healthy, given that they'd naturally be losing their leafs around now? For example does that change whether I should keep them indoors/outdoors, give them more artificial light or let them be in the partial shade of an indoor spot during winter, wait before I plant them in pots at all (in which case would they sit in water, or just left dry over winter), etc.
