When winter has worn out its welcome, gardening events erupt to welcome back sunshine, warmth, renewal and that ritual turn of soil, seeds and mulch. The Myriad Botanical Gardens and Crystal Bridge Tropical Conservatory in downtown Oklahoma City is just one of the many April events with the goods and good advice for making your garden a retreat. Look for the Myriad Gardens Annual Plant Sale April 5-7 (www.myriadgardens.com). The Tulsa Garden Center has SpringFest Garden Market & Festival, April 13-14, with a selection of plants and products plus natural and sustainable goods (www.tulsagardencenter.com). Remember, too, that many outdoor pro-local markets open in mid-April, including OSU-OKC Farmers Outdoor Market (www.osuokc.edu/farmersmarket) at the OSU-OKC Horticulture Pavilion in Oklahoma City and the Cherry Street Farmers’ Market (www.cherrystreetfarmersmarket.com) in Tulsa on Saturdays.
