Heads up, Colorado gardeners! The National Weather Service has issued a Freeze Watch for Thursday night (10/15) into Friday morning (10/16), with temperatures potentially dropping to 27–33°F across Fort Collins, Boulder, Denver, and surrounding areas!!
We’ve been growing our own food since 2013 in this region and we ain’t scared… Here’s how to protect your gardens before the cold arrives!
🍅 VEGETABLES: Harvest tomatoes, peppers, cucumbers, and squash before Thursday evening. Cover tender greens with frost cloth or blankets. Hardy crops like kale, spinach and root veggies can generally tolerate a light freeze.
🌸 FLOWERS: Cover frost-sensitive annuals like marigolds, zinnias and nasturtiums. Harvest any blooms you want to save! Established, cold-hardy perennials will be just fine!
🌳 TREES & SHRUBS: Most established, cold-hardy trees will handle this freeze. Protect vulnerable new plantings, mulch around roots, and water only if the soil is dry!
🪴 POTTED PLANTS: Bring tender plants indoors or into a garage.
🧤 FROST PROTECTION: Use frost cloth, sheets or lightweight blankets, securing the edges at ground level. Remove coverings when temperatures warm.
💧 DON’T FORGET: Disconnect hoses and protect exposed outdoor plumbing!
And remember, gardening season does not end at the first frost! With a little care we can get a few more weeks out of our plants!
🌱 Stay warm and happy growing!
