I love arugula too! I can eat a bowl full of it.
Easy to plant, grows like a weed. When its warm you must keep eating or at least cutting before the plants bolt. So you can have salads daily. Tastier before it bolts, that is for,sure, so get out there every evening and cut.
i was actually hoping mine would bolt but it never did, being a fall crop. i harvest all my non-hybrid seeds each year. i love doing that and it makes me feel self-sufficient. and cheap! lol. so i just ordered another package of arugula seeds, hopefully my last!
but yes, bolting does make lettuces bitter. i need a spring and fall crop, because the heat makes the spring bolt and i can get seeds. but the fall crop is SO much easier to grow I found out this year! less bugs and less having to cover because of heat (although covering because of frost becomes an issue).
but how did lettuce and tomatoes ever become a popular combination? by the time its hot enough for good tomatoes, my lettuce has bolted. then when the fall crop matures, the tomatoes have quit production. weird.
What does bolt in a plant mean? I know it does not mean they get up & walk away at night ; )
