Worm tea can be heavily diluted, and used as a drench or a spray, but I like to add about half again of water. Since the beginning of the year, I've used it exclusively on the orchids, with some very gratifying results.
I don't feed my orchids as often as I should, but most of them flower on and off regardless. However, for years I've had a large cattleya growing on the north side of a coconut palm trunk. It flowered once, nearly 10 years ago, but now it's got two huge blooms! I was stunned to find them a few days ago.
And a vandaceous orchid that's not flowered before produced some delightful blooms of the palest purple, a color I've not seen before.
