— And 5 Veggies You Can Still Plant In August. Start your late season crops in the heat of August to enjoy a second harvest in September and October.


You may be in full summer-harvest mode, picking zucchini, tomatoes and basil every night; or, maybe you got sidetracked this spring and your plans to get the vegetable garden going just never quite materialized. Either way, it’s already August, and in many parts of the country, it’s time to plant fall crops!

The timing for fall crops can be tricky because you need to leave enough time for them to mature before cold weather sets in. In addition, fall crops may need a little extra time to mature because they receive less daylight as the season winds down. In most temperate growing zones, fall-planted crops will be ready to start harvest in September and October. In very mild climates like the Pacific Northwest (where I live), many of these crops can survive through the winter, providing much needed garden love in the gloomiest months of the year. Fortunately, a successful fall garden hinges on only a few simple rules:


By the time many people start thinking about fall crops, it’s already too late. To ensure a successful fall and winter harvest, you need to start many of your late season crops in the peak of summer. In most regions, this means planting in the heat of August to give your crops time to size up while growing conditions are still good. Some fast growing fall crops like lettuce and radishes can be planted into late September; but many desirable fall crops like broccoli and carrotsneed several months of prime growing conditions to mature before frost and low light levels set in. When in doubt, plant your fall crops a little early.


Make sure you know your crop’s life span: Each crop has a relatively predictable lifespan, meaning that you can anticipate approximately how long it will take to reach harvestable size. The life span of the crop is usually defined by the phrase “days to maturity,” which will be listed on the seed package or plant tag. Days to maturity will vary a bit by environmental conditions, but these numbers should be fairly accurate. As a general rule, you should plan your planting so that the crops have time to reach maturity before the first frost (find out what your local frost date is here).


Get out there and harvest your spring and summer crops: Planning a successful fall garden hinges on the proper management of spring and summer plantings. In most gardens, where space is limited, it is imperative that early season crops are harvested and removed from the garden in a timely fashion. This clearing makes room for the new fall plantings. Crops that may be finishing up in your garden mid-summer include garlic, onions, potatoes, carrots, beets, cauliflower, cabbage, and broccoli. You might also still have some spring salad greens that are exhausted and ready to come out. When choosing which fall crops to add to your garden, start by making an inventory of currently harvestable crops. This will allow you to determine how much space you will have available and prioritize the fall plantings you care about most.


Fall and winter gardening turns your vegetable plot into a giant refrigerator. During the fall season, cool weather allows crops to hold longer in the garden once mature. Crops like broccoli, cabbage, and kale can live for months in the garden after they reach maturity. Even fast growing crops like spinach, cilantro, and lettuce will hold their quality for much longer when planted for fall harvest. If you plan properly, you may be able to harvest from the garden all through the cold season and into the early spring.

Now that you are primed to select crops that still have time to mature in your region and have opened up space in the garden for new crops, it’s time to discuss fall crop options. While not comprehensive, the following list includes the most popular and commonly requested crops for fall planting in our gardens:

Carrots (about 70 days to maturity)

Direct-sow carrots into the garden in rows spaced 6-8 inches apart. If your garden has drip irrigation, sow the seeds along the drip lines. Carrot seed is very small and can be hard to sow precisely, so aim for 5-8 seeds per inch. You’ll need to thin the plants to one seedling per inch once they have germinated, but overseeding helps ensure a fully filled-out row. Once fall carrots are mature, they can hold in the garden for months. You’ll find that carrots typically taste even better than normal when harvested in the fall after a few light frosts. If you’re gardening in an area that experiences hard frosts during the winter, pull all of your carrots out of the garden before frost sets in or mulch your beds with a thick layer of straw to protect their exposed crowns.
