There are many cool season veggie crops that prefer cool daytime temperatures of 60 to 80 degrees, and down to 40 degrees at night.
It’s not too late to grow some cool season veggies from seed. When choosing a variety, check the “days to maturity” for a shorter (50 day or less) duration. This will ensure proper germination and strong plants facing cool night weather. Spinach, lettuce, peas, radish and beet seeds can be sown and do best in lower temperatures. They will still need protection from potential frost, such as seed guard and frost cloth (available at Fort Collins Nursery).
We also have a nice selection of starter plants including Brussels sprouts, broccoli, cauliflower, cabbage, lettuce, and kale. Check back throughout the months of April and May for new arrivals including all of our warm season varieties!
