This is a quickly growing green which is best grown in cooler weather - we prefer to grow it in the fall where they are not bothered by flea beetles.

”Some people love arugula tossed into a mixed salad and some people don’t. I am becoming more fond of it with a mixed “greens” salad I guess…as my palette matures. The first packet of seed I bought was a 10 cent packet from the Hart Seed Company. This was in the 1950’s and it was a packet of arugula. It quickly grew into a wild patch of leafy plants and at that time it smelled so much like skunk that I couldn’t bring myself to eat it. I am somewhat relieved to hear that Julia Child thought the same. That’s all I have to say.”

Plant seed directly in the garden a few seeds per inch in a furrow. Cover with 1/4 inch of soil. Like early radishes this is a fast growing crop that needs fertile ground and well-drained soil. Water when the soil is dry. Ready to harvest in a month. Summer heat will cause the plant to bolt and you can collect the seed.
