I'm getting close to getting a few of these. I wanted to kill as many slugs in that area as I could first and I want to plant it closer to the rainy season. I'm going back to that nursery next week with a friend so if there are fewer of them than when I was there before I may have to go ahead and get them. Our rainy season usually starts in the first few weeks of June.
My beer loving slugs are getting trapped every night, it's amazing how many there were and how huge some of them are. I also read about spraying the area with ammonia and water to kill the eggs, will do that too.
The bed I have in mind is over an old well, now used for drainage, and the fish tail palm there must have gotten its roots into the well, it has grown so fast. I shouldn't have much trouble keeping it moist in the dry season. Still, it would be better to start it out with daily rains.
