Soils should provide good water holding capacity and good internal drainage, and a pH of 6.0-7.0. Since arrugula may be harvested late into the fall, soils should be chosen that allow harvest in moderately rainy conditions. Have germination checked before planting if germination value is not known or current. Pelletizing seed allows precision planting. Stagger plantings once or twice per week, planting only what can be harvested, bunched and sold during that interval.
Arugula can withstand light frosts.
Transplant only for the earliest crops. Spacing depends on cultivar and crop being grown. Close spacings cover the ground quickly and reduce risk of soil contamination of the product from rain or irrigation splashing. These recommendations are intended to provide adequate fertilizer.
