regarding potting medium, temperature, fertilizing, air movement, watering, and
more. To get your free guide click on the following link to tell us where to

The October meeting will be Tuesday, October 3rd (earlier than usual) and will be presented by Tomas Bajza.

Tomas will be speaking on “Growing Miniature Orchids” .

An orchid lover and addict, Tomas originally came to the USA from the Czech Republic and settled
down in hot tropical Miami, Florida. He adored orchids during his teenage years, but at that time
there weren’t many to see in his country. Even though he’s been living in Florida and surrounded by orchids for so many years, Tomas started growing orchids in Florida in 2008. He started with the usual grocery store selling orchids, like Phalaenopsis and Dendrobiums, slowly adding some
Cattleyas and Vandas since these were the orchids that everyone in Florida grows.
2010 was the first time Tomas had ever seen a miniature orchid. He had no clue that such a thing
even existed! He fell in love immediately and ordered a few. When they arrived, they were even
smaller than he ever imagined. That was it, he was bitten by a “huge” miniature orchid bug. He is a
very stubborn grower and does not listen to anything, like the word “impossible”. He likes all
orchids, but has a huge amount of love for cold to intermediate growing species. He was told by
many growers that due to the hot climate in Florida that these types of orchids could not be
grown.  Through extended research, reading and being active in different orchid boards and orchid
groups, He’s learned tremendously and became an advance grower for miniature orchids.
