While we aren’t completely out of freezing temps yet, we are really close. That means we can finally get our hands in some dirt.
Here in Zone 5, we can start planting Hardy and Frost Tolerant Vegetables. These vegetables tolerate cold temperatures the best. The seeds germinate in cool soil and their seedlings are frost tolerant. They will grow in daytime temperatures as low as 40 degrees Fahrenheit. Cool season veggies can produce more sugar and sugar water freezes at lower temps than water, which actually keeps the water in the plant cells from freezing and bursting, protecting the plant. So go for it!!!! Put the gloves on and start moving that soil!!!
Use these Guides as your schedules for what and when to plant indoors and out.

Here’s a handy map to help you find your zone.
You can search your local Master Gardener’s website for greater detail on fruits, veggies and herbs that suit your Zone the best. Keep in mind that a cool weather veggie will stay a cool weather veggie no matter where you live. Eggplants, peppers, Basil and Tomatoes are always going to need heat and Spinach, Arugula and Cilantro do not like heat. Nothing will change that. The only difference will be how long it is hot or cold in your Zone and your Master Gardener Extension program can help answer those questions specific to your region. Ours is http://urbanext.illinois.edu/veggies. Every state and Canada has extension programs, and they’re always staffed with happy people because gardeners are Zen 🙂
