1. Everything seems to grow in Maui. I exempt stone fruits and really cold-loving stuff, but only wind is the great equalizer. Corn looks funny lodged at 45 degrees off vertical.
2. Weeds are so easy to grow - corn is not (as yet).
3. You have to water carefully, as the rain doesn't last long enough, except to spot the windows.
4. It's hard to have too much compost or mulch.
5. I never saw snails the size of small conch, or slugs as big as my hand, all black with a tan stripe, like some sort of race car. They can fly straight down into the gulch really fast.
6. Whatever you knew about trellises, just increase them to supersize, anchored to hold the Queen Mary in port. A block wall isn't enough of a windbreak.
Meanwhile, back in OC, I have only citrus and avocados, with a giant bush of rosemary, making really nice skewers for kabobs. Making a weird appearance peaches have come in like never before, bending and breaking even the big branches, so pruning this year will be easy. Who knew?
