LarryW said:I I have not been to gardens in Florida, but I think I have read that most of the big hybridizers use shade cloth over their hybridizing areas or have greenhouses in which they hybridize.

Ted Petit uses shade cloth over his blooming plants and lines the seedlings out in rows in a greenhouse with open sides once they've sprouted and are growing well.
The Salters have their breeding stock in pots in a greenhouse, and that's where they do their hybridizing.
Nicole has all of her stock in pots in the open, but I don't know what goes on in her greenhouse - it was sealed off from access during last year's Mecca.
Floyd Cove has their seedlings out in the open, much of their stock under shade cloth, and I'm not sure what they use their greenhouse for.
At Watermill Garden there was a small greenhouse, but it was empty during the Mecca.
Reilly gardens doesn't appear to have a greenhouse.
