Plant These 6 Fall Crops Now for a Last-Minute Harvest!


We typically associate September with harvest season here in Edmonton, but you can still sneak in one last round of crops before winter! While most crops need a bit more time to grow, some cool-weather crops mature quickly and thrive in the mild temperatures of September and October. However, the weather is always a bit unpredictable in our neck of the woods, and it’s typical to experience a few frosty nights during these months. You’ll need a game plan ready when the forecast calls for frost overnight.  


Getting Prepared for Growing Fall Crops in Edmonton

The sunny daytime is usually warm enough for your fall crops, but nighttime is when frost becomes a risk. Crop covers like burlap, landscape fabric, or old bedsheets are awesome for frost protection. Just gently spread the cover across your plants and use stakes or weights to secure the corners so the material doesn’t blow away. In the morning, remove the covers so your plants can get some sunshine.

Growing fall crops in containers is a great idea. That way, you can move the containers indoors overnight, then bring them back out in the morning. If we get a freak snowstorm ahead of schedule, you can try placing the containers near a bright window or use a grow light to help them keep developing until they’re ready for harvest. We recommend keeping your potted outdoor crops separate from your houseplants to prevent hidden pests from spreading.  


The Best Fall Crops to Plant Now

Ready for one last harvest of fresh veggies to tide you over as winter approaches? Plant these six cool-season vegetables and herbs in early September so they’ll be ready before the winter freeze.

When the outer leaves measure 6 inches long, your spinach is ready for harvest; this typically takes about six weeks. Try not to pick more than 1/3 of the plant at a time so your plant can keep growing harvestable leaves until it’s too cold to continue.  



These fast-growing root veggies can mature as quickly as one month! Some varieties take a little longer””around 45 days””but they’re by far one of the best crops for a late-season harvest.
