Hi all! This is my first foray into bonsai so bear with me but I've picked up a young Lawson cypress and it's been quickly deteriorating over the past few days. I yanked it out the side of the road (possibly attached to mother tree?) and it had some developed roots and lovely green foliage. I've since potted it in coarse gravel and for a few days, kept it on a windowsill and frequently watered it. Despite (or probably as a result of) this, the foliage very quickly dried out and fell off and I think it might be on it's way out.
I live in a temperate climate where it's approaching summer now but I can't easily place it outside for a few days yet (not home). Any recommendations for care? What am I doing wrong re: watering, soil, etc?
Thank you in advance!
