There are plenty of delicious veggies you can grow in the cooler months of spring and fall. This list features quick-growing options that are ready in just six weeks. Come see these leafy, green, delicious choices.
Fast Growers for Cooler Weather
If you have been here before you know I love cool weather gardening. Free of the intense heat and humidity of summer, it’s a beautiful time to be outside and the conditions are ideal for many cool-loving veggies.
Spring and fall are the time for growing nutrient-dense, leafy greens, and, if you have never been particularly fond of them, it is time to give them another try. I know we hear this all the time but it’s true: nothing compares to the flavour and juiciness of freshly-picked spinach and leafy greens! That limp, lifeless stuff in the grocery store shouldn’t even be sold as food!
All the veggies on the list (below) have edible stalks and leaves which makes them ready to pick at any point in the growth cycle. The estimated harvest day is simply marks a point where growth may be at a maximum. Plus, many of these varieties are ‘cut and come again’, meaning, you can trim off leaves for your dinner salad, leaving an inch at the base, and new leaves will grow—sometimes several times over. Bonus!
You can start sowing cool-tolerant crops when your garden soil temperature is consistently 50 to 68 °F | 10 to 20° C.
Know Your Hardiness Zone
While this is probably not a concern for short-term veggie crops, if you are a beginner gardener, the first step is to know your gardening zone (for plant hardiness) and learn which plants are best for your growing conditions and climate. Invasive species (plants and animals) are huge problem these days and it is critical that gardeners are making safe choices that benefit the environment.
- Frost Dates Calculator | This calculator at Almanac.com is simple to use. Enter your city and state or province to find your first and last frost dates and number of frost-free days.
- Plant Hardiness Zone | United States and Canada
Plant hardiness zones are listed on seed packets and plant tags.
Growing zones are usually displayed on plant packages, tags, and seed packets to assist your buying decisions.
