Thank you all info! I've a couple more ?s, if you don't mind.
(1) cuttings, can they be saved to grow at a later time, if so how?
(2) I've got some 6"er is 5 gal buckets, is too late to move outdoors now and will they mature to harvest outdoors? at 3000m or 9000' it can snow abt 20 Sept, but then it gets Indian Summer, temp above 40degrees?

(1) Sure, wrap a damp paper towel around the stem and stick it in a cool place (I have used the refrigerator and - accidentally - that space between the couch and end-table among others). When you're ready to root them, cut off the end of the stem for best results.
Err... Depends on how much time you wish to keep them, of course.
