Planting a Fall Garden

Summer is coming to an end, the nights are getting chilly, and our vegetable garden is running out of steam here in Zone 5. Thankfully, the fall season is a great time to plant cold weather crops that we are able to preserve and save for eating our vegetables throughout the winter months!

The Best Time to Plant a Fall Garden

Here in New Hampshire, fall temperatures start to set in at about the beginning of September. August is the month for harvesting all of our summer crops, while in the meantime, our fall garden is just beginning.

Deciding when to start your fall garden all depends on the specific things you are trying to grow. For example, radishes are a very fast growing vegetable (only taking about 30-35 days to mature), whereas carrots take a longer time to grow (usually around 70-80 days). Therefore, when thinking about what to plant, you want to make sure that you have just the right amount of time available to be able to harvest your fall crops before any harsh frosts come through.

In our opinion, going by the information that is on the back of your seed packet is your best bet. The information for fall planting/sowing on these packets is completely based off of your first frost date, and from there it will tell you how many weeks ahead of this date you should sow your seeds. It should also give you other details such as if you should sow your seeds inside in flats or if you should direct sow. Different types of seeds require different amounts of care.

Please see below for some examples of this.

Best Vegetables for a Fall Garden

Ideally, we wish we could plant some more tomato seeds or cucumber seeds when our mature plants are done giving us their bounty, but unfortunately, they would not survive the cold long enough to bear any fruit. Instead, we plant the following seeds at their respective sowing date in order to get a harvest before winter!

Our favorite fall crops include:

  • kale
  • carrots
  • radishes
  • spinach
  • cabbage
  • beets
  • garlic (we overwinter these, i.e. plant in the fall and harvest in the spring)
  • onion (we also over winter these)
  • leeks
  • lettuce

There are so many options out there when it comes to deciding what to plant for your fall garden. Do not think that your favorite summer hobby is over just because colder weather is coming. The second season has just begun!

How to Extend your Growing Season

For most of us here in the northern states, frost is an extremely limiting factor when it comes to growing in the spring and even the fall. Establishing a fabric row cover is both an easy and inexpensive solution to extending your season.

This year we decided to get an early start on planting our radishes, spinach, and kale. We direct sowed all of these right into our raised beds. We then decided to install a fabric row cover. The specific one that we bought is very light weight and provides a frost protection of up to 28°F while still allowing a transmission of light of to 85%. (We will include the link to this cover below). We only used a fraction of the fabric for one 4x8 raised bed. We will get several more covers out of the rest of the fabric we have leftover.

This row cover was super easy to set up (along with a little bit of PEX piping), and allowed us to plant our fall crops earlier without them bolting. This cover will also allow our veggies to stay in the ground for a longer period of time because they will be protected from harsh temperatures and frost will not be a problem for them.
