Is it time to plant your garden with vegetables to ensure a healthy bounty for your summer table? The best way to know when to start sowing is to get a soil thermometer (less than $5) and make sure the soil has reached at least 35 degrees. But it's generally a good bet to start sowing the coolest germinators — spinach and lettuce — first. A couple of weeks later, follow up with crops that like soil slightly warmer: kale, bok choi, radicchio, cabbage, collards, radishes, turnips, carrots, peas, broccoli, fava beans and onions. Wait another week before sowing Swiss chard, parsley, cauliflower and parsnips. It’s going to be a healthy and delicious summer!
