As long as you get the basics down, growing them in containers outdoors can be simple yet rewarding. Green onions have small root systems, so a container that's about 6 to 8 inches deep is ideal.

By selecting resilient plants like collard greens, leeks, rutabagas, mâche, mustard greens, and turnips, you ensure a steady supply of fresh, nutritious produce throughout the colder months.

Salad greens ... soil to grow them and less water, too. Use a vegetable potting mix to sow seeds. Don't use garden soil for your indoor plants because it won't drain well in a container.
