May is a busy month in the garden. One of the most important keys to garden success is to know what planting zone you live in. Why? Because it determines what you can plant, where you can plant it, and when to plant. I live in zone 8. If you are not sure what zone you live in, you can find out here.
I found a free monthly organic gardening guide to help you plan and maintain your garden. You can get it here. https://www.kellogggarden.com/wp-content/uploads/Monthly-Organic-Gardening-Guide-By-Planting-Zones.pdf
Now that you know your zone, it's time to plan what to plant and your other garden chores.
