I keep forgetting lol sorry I don't know what to tell you with that, just the I've had very bad problems burying RW in soil. Matter of fact the two outdoor plants that died were in RW buried in soil. Two others almost died but I was able to surgically remove the RW once I uprooted the plant. Had to be very delicate and they managed to recover with minimal shock or stunting. Problem is the RW retains water to no end and it rots the stem and discourages the roots to seek out water so they sit and rot.
You could dip the cutting and put em right into the soil as well. May have a better end result that way. I've read about so much that I don't need to use but I'm glad I have something to share with you given we use different mediums.
