I couldn't agree with you more, when you work for a sprawling school district, with a plethora of landscape goodies, you just CAN'T help yourself!, I go through a bottle of the stuff a year! But if you've ever had to deal with cactus you'd know that if you're out to get rid of it, cut it at the bottom - I use a scuffle how - and set it on a rock or piece of wood and let it dry out. I learned that if you just toss it and it lands on soil, you pretty much just transplanted the dagnabbed thing!
I had a jade plant that I wanted to propagate and give out to friends, luckily my sister was visiting, all she did was pull off a few leaves and stick them into the surrounding soil.
. "Leave them there until you see new growth on the lower curve, then take them out and put into new pots." needless to say, it worked!
I guess that if it's something thats special TO YOU, your best bet would be to use it, just for insurance if nothing else, but I have also seen plants get treated like rags and still thrive.
Anyway thank you for the thumbs up! I really appreciate it.
