It’s time for early spring planting of spinach. "Spinach enthusiasts celebrate their love of the vegetable every spring and fall here in Louisiana," says LSU AgCenter horticulturist Dr. Tom Koske, himself a hopeless addict.
The horticulturist says spinach is in the beet and chard family and needs cool weather to grow. It will tolerate quite a bit of cold, so plant in February and up to 60 days prior to expected high temperatures. "We don't see much spinach left by June; it goes to seed quickly then," Koske notes.
Spinach needs a loamy, non-acid soil of pH 6 to 7. More acid soil will ruin your chances. Incorporate 4 pounds of 8-24-24 fertilizer per 100-foot row (or per 330 square feet). A side dressing of ammonium nitrate will be needed in three to four weeks after the plants come up. Apply 3/4 to 1 pound per 100 foot row.
Soak spinach seed for several hours or overnight before planting at 1/4-inch deep. Seeds germinate in 1 to 1 1/2 weeks.
Several varieties are available to choose from, Koske points out, especially in the newer and more vigorous hybrids. There are smooth leaved type, savoyed (or crinkled) and in-betweens called semi-savoyed. The smooth leaved and semis are easier to wash at preparation time.
Koske says some good producing varieties are Melody, Tyee, Olympia, Coho, Skookum, Hybrid 7 and Bloomsdale.
If grassy weeds take over, Poast herbicide will take them out. A spray of Basic Copper fungicide will control most foliar diseases, and Malathion insecticide will control aphids and beetles.
