i guess it's been about a month. 1st set was black, 2nd set was green, and 3rd was red.
1st set went into cup with very little or no root. just bud breaking and "root initial".
2nd set had about 1/4" roots with most of them having leaves breaking out.
3rd set had about 1-3" roots.
out of those, 2nd set produced most roots. 3rd set came up fast. 1st set didn't have much issue either. very few out of 1st set fail to show root outside of peat pot, but at this point, they all have roots and most vigirous rooting was from Calvert that was in 1st set.
at this point, i would say it really doesn't make much difference when they go into soil mix. it seems the failure to root, at least for me, is based on each individual cutting and just my luck.
one thing i did notice is out of 4 that doesn't have root or top growth, 3 of them are cuttings with terminal bud.
