From Our Home to Yours

Dalen Products is an independently-owned Family business that began in 1975 when Neal Caldwell first brought his Vent-o-matic Greenhouse to the market, helping make gardening easier for Americans. At that time, Dalen Products could only be purchased through mail-order catalogs, but as the seasons have changed, Dalen Products are now available to purchase all across the United States. Look for us in garden centers and stores like Walmart, Costco, and Amazon. A long time has passed since 1975, but Neal’s legacy continues to thrive as many of his inventions continue helping gardeners all across the USA overcome their gardening challenges. Some of Neal’s original products are unchanged since conception, while others have been continuously innovated and improved as the years have passed. Neal’s son and grandson continue to work at Dalen, but the real heroes are the great Tennesseans who continue to show up for work. As a business, there have been ups and downs, hard winters and scorching summers, but we continue to persist and blossom on the pretty days. At Dalen, we believe a better world can be grown through gardening. We hope you will join us on our mission, because this world is ours to share. Gardeners can cultivate beauty for us all.

Dalen Products is located in Knoxville, TN, USA and a proud owner of a Protected Wetlands and Bird Sanctuary. Although our goal is to grow beautiful and life-promoting gardens all across America, we think it's important to set aside and protect larger parcels of land for wildlife to live and thrive. In our protected wetlands in West Knoxville, we love seeing Red-Shouldered hawks hunt for snakes, Blue Herons feeding on fish, Eastern Box Turtles basking in the sun, and Musk Rats swimming around having a good time. All sorts of animals visit our wildlife refuge, more than we could count or name. In the grand scheme of things, our protected wetland is only a drop in the ocean of life, but at Dalen, we believe the little things add up to a whole lot.  Every little detail matters, every garden counts.

The Dalen History

When Neal Caldwell, a mechanical engineer by trade, and his wife, Alice, built their Williamsburg-reproduction home in Knoxville, TN, they started with a vision, their sleeves rolled up and a lot of moxy. Through trial and error, Neal put his training to the test and developed several products to help establish his yard and garden on land that so many others had written off. The marriage of his professional talents, his passion for gardening and the inspiration to make his family’s house a “home” resulted in the birth of Dalen Products, Inc. in 1975.

Humble beginnings.

Since 1975.
