Ed is a big proponent of raised beds. He says we don't necessarily need to build frames around them. We should dig about a foot deep, and then mound more dirt on top, about 8 inches, so the roots will have a plenty of room to grow down. With mounds (or raised beds), you can supposedly grow more in a smaller amount of space, with narrow spaces for walking between wide rows of plants. This is our plan, using that advice:
We are doubling our garden in size, which means we have to start digging soon. We are in zone 6a in coastal Massachusetts, and our last frost date is around May 15. Ed says we could start planting seeds for things like beets, arugula and spinach as early as this weekend, which is 3-4 weeks before last frost. That's not going to happen, though, because we've got to paint one of the bedrooms this weekend before the floor guy comes next week. More on that later.
