Arugula - Key Growing Information

SCIENTIFIC NAME: Eruca sativa, Diplotaxis spp.
CULTURE: Arugula prefers a fertile, well-drained soil, with a pH range of 6.0-6.8 in full sun to part shade. Arugula prefers cool conditions and is hardy enough to over-winter in many locations from late summer and early fall sowings. It is also well-adapted for growing in cool greenhouses and high tunnels for winter production. Direct seed 1/8" deep from early spring onward @ 30-50 seeds/ft. Germination should take 5-7 days. Keep soil moist to slow bolting. For a continual supply, plant every 2-3 weeks until 1 month prior to first avg. frost date.
HARVEST: For bunching, cut just above soil level. For baby leaf, clip leaves for cut-and-come-again. After plants flower, the leaves can still be used but taste is sharper. Flowers are also edible.
PEST CONTROL: Flea beetles can be controlled by covering the crop with floating row covers from the day of sowing. Prevent diseases with crop rotation and sanitation.
