Thanks to both, I'd think that liquid root stim would be about as effective? If not I'll check up at the lumberyard where I shop to see if I can find some powder. Was going out this afternoon to pot them up however the heat index is 108
so I'll have to wait until the morning. The photo is of my 16 4yr old seed grown Plumeria. Found some old powdered root starter out in the greenhouse should it still be good? I've had it for quite a few years.
