One of the most common questions we get here at Snoozing Dogs Farm is when to start seeds and plants. We’ve put together a calendar to share with you. Remember that Highlands Ranch sits higher in altitude than Denver, so our dates are a little later than what you see in the city. Our last frost date is May 13. Don’t be tempted by those plants in the nurseries. Stick to your guns and follow this guide – even though its 80 degrees in March!
