Sow Seeds again and again

I just started my third batch of seeds of the year- I have lots of beets, kale, lettuces (I am trying Iceberg this year), leeks & yellow onions. It is a good idea to start seeds every two to three weeks in the northwest, because of the variability in weather and because you will want to have some plants to eat that are maturing each week. I like to eat salads from the direct seeded area between the seedling planted in the garden.  It is hard to remember to keep seeding while you are harvesting more lettuce than you can eat, but you have to, or you won't get good summer salads. I learned to put squash seeds into the lettuce bed near the end of the harvest, and by the time the squash are big enough to throw shade on the lettuce, you are done with that bed!
I just took a cool webinar class about crop rotation, and am going to try to incorporate some of the things they talked about in some of the gardens I am planning this year. I never plant the same food in the same beds year after year, but I have not kept track of exactly what was sown where in my garden... this year it will be different! I even learned a cool way to track the garden in a simple excel sheet. I will keep updating my progress through the season...
