I was never a fan of arugula. Too spicy, to peppery for my taste. What I learned was that if you harvest it when smaller, grow it in cooler weather, and experiment with different varieties, you’ll find it looses much of the spicy edge. This particular variety is Astro, and it is milder when grown this way.
This was direct seeded about 12 days ago on a very wintery day. As you would expect, this would come up faster on a slightly warmer day, but I like to see how far I can push the limits in our 4 season climate.
