Nice to meet you.

Hi! I'm Callie Works-Leary, and I'll be your instructor. 

I'm an expert garden educator, a Texas Master Gardener, and the founder of The Dallas Garden School with over 17 years of horticulture experience. I specialize in growing food and flowers in an urban environment. 

My passion is teaching others how to achieve professional results. 

They call me the "Tomato Queen".

I must admit. I laughed the first time someone called me that. But  that's what happens when you grow over 500 tomato seedlings of 32 different varieties every year.

It all started with "Green Zebra". My favorite heirloom tomato. It's unique green zebra striping and tangy,  gourmet flavor had me completely hooked.

That was 16 years ago - in my Midway Hollow backyard - when my journey to know everything there is to know about growing tomatoes in North Texas began. Today, after gaining a horticulture education and working professionally, I grow and sell heirloom tomato seedlings to people all across the country and harvest hundreds of pounds of tomatoes. 

My passion is helping others to enjoy the success and fulfillment of growing their own food. Will you join me as I share everything I know about tomatoes?
