the vinegar we buy here is 5% - I think 20% is high (especially when diluting and using around "wanna keep" plants)
I bought a varigated brug today for $1.99 :-)
No, I haven't, but I'm going to look into it further. Anything Malcolm Beck says is as good as gold in my opinion. You'll have to keep us posted on the results!
Yikes! Last night I had another Brug dream. This one was scary. I dreamed my variegated brug was outside on the ledge and that I sat too close to it and knocked it over, killing it. I think this dream was spawned from a real life accident last week, when I DID do that to my one and only Cypress Vine I had started from seed, and was sunning and hardening it off. It didn't make it.
However it was nice to wake up this morning and see that brug doing very well.
