The one's from Lee Valley are set of 5 for $11.95...
(that's about $2 something each)
But I originally used duct tape...
for my rooting experiments...
It's a long story..
When I was a kid, just getting into house
plants,
I had an Angel Winged Begonia... I loved, it was so tall and pretty.. and I was moving it one time and the top half broke
it was probably about 3/4 of the way broken off..
and in my early, "believing stage", in my mind, I thought if I took duct tape, taped it around the stem *backwards, so it stuck apon it's self and not the stem* and thought it would regrow..
Well, a bunch of weeks later, I tugged on it..
and it seemed sturdy..
Well, I left it a bit longer to make certain..
When I opened it up, there were a ton of white roots all along the node of the stem where the leaf met the stem.. and in the darkness of the ducttape, it rooted all on it's own...
Hence came the begining of a humongus interest in gardening.
So, taking the duct tape works..
Also, taking a ziplock baggie, slit down on side of the bag it'self.. put in some spagnum moss like or a bit of bagged soil, or maybe even some damp peat moss and shove it in the baggie on either side of it like...
Then take that baggie and wrap it around the stem of what you want to propagate and then duct tape it around....
***sometimes slitting the
plant/stem/bark about 3/4 of the way thru, so the momma
plant still can feed the part you're trying to root but will feel threatened enough to make roots too***
