Just returned from a Propagation Specialist training in Montgomery County and wanted to add my voice to the crowd singing the praises of the Montgomery County Master Gardeners. They really set a high standard for the rest of us by installing and maintaining an amazing variety of demo gardens - floral, fruit, butterfly, xeriscape, bog and pond - and in their "spare time" they've raised the money for and installed a huge multipurpose building for their Extension office. They even have real china cups for the coffee! Talk about attention to detail... If you have reason to be in the Houston/Woodlands area - it's worth the drive to Conroe to see what can be accomplished with a big dream, hard work and a team spirit. Of course, it doesn't hurt to have Tom LeRoy as coach/Extension agent.
