all my cuttings are outside, i dont often take cuttings but when i do i leave em outside
i have two large field maple branches stuck in a tray in spag moss and soil on my balcony im attempting rafts with them and there is also an english elm raft attempt in the same tray, in another tray i have english elm root cuttings. i just keep the soil moist. ive had large trident branches root on my balcony before inside a bonsai pot that was then stuck in one of the overhanging troughs. the troughs are filled with soil and collect water which in turns provides humidity around the pots. it worked that one time, the trident cutting produced roots that found there way into the trough beneath. i didnt use any plastic covering.
