Best rooting compound?
We are planning to root a cutting of an old Granada. This rose is 40+ years old and appeared to be on its last leg with a single old gray gnarly trunk. We cut off the single remaining cane and there is ONLY ONE stem to use for rooting. We have one chance!
I saw some Dyna-Grow yesterday and had it in my hand when I noticed the price: almost $30 for a small container. Then I remembered the bottle of liquid seaweed we already have at home and wondered if I could use that instead.
We have only one chance! What rooting compound would you choose for this?
