So this fall I have taken coleus cuttings...two are rooted in soil, and I have a bunch rooting in water. Once I get them all into pots, what are the best conditions to overwinter them indoors? Few sunny windows here during winter (I live in the Pacific Northwest) and my usual "winter plant room" where my cactus collection rests is on the cool side. Do I need grow lights? Warmth? Any suggestions welcome!
