Horticulture

The Kerr Center’s horticulture program shows farmers and gardeners, from beginners on up, how to sustainably grow vegetable crops, focusing on Oklahoma organic horticulture’s unique challenges.

The six+ acre Cannon Horticulture Project, certified organic in 2011, is founded on organic system design and management.  Organic certification was allowed to lapse in 2017, but organic management continues in order to permit easy re-certification in the future.  Demonstrations are tailored to organic home and market gardens in the same size range.
