She's dropped the gardening know-how on WFAA's Good Morning, Texas and has a new book (Best Garden Plants for Texas) slated for spring, but for now, it's her free green advice on the web that Dallasites should be following. Leslie Halleck is the self-described plant geek behind Halleck Horticultural. As she explains, she provides technical horticultural consulting and business strategy consulting for industry, but "much of [her] time is spent generating horticultural content for green industry companies so they can better educate their audience." Impressive to be sure, but it's the byproduct that benefits Dallas' brown and wannabe green thumbs most — the free gardening advice Halleck shares on the Halleck Horticultural blog, Facebook page, Pinterest, and Instagram account. From her East Dallas hub, Halleck and crew provide peeks inside the industry as well as more intimate scenes from her own garden. She offers suggestions, like what to do with an overabundance of tomatoes or alternatives to planting tulips in a row; a series called Cocktail Gardening, complete with recipes; portraits of garden critters (including her own pets); a glimpse at urban homesteading; and seasonal planting tips.
