Mid-August is rolling around, and with it comes some vegetable planting possibilities that will feed you late into autumn and early winter. This is a great time to clean out some of the garden beds that have finished producing and replant them with some fresh crops for late season harvest. Here are a few options that you might want to consider incorporating into your later summer gardening routine.
A note on flea beetles and row cover. Flea beetles are little, black and jump around on your plants while making tiny little holes. They love anything in the brassica family - cabbage,broccoli, arugual, mustards, collards, etc. Row cover is a white fabric used to keep out insects and/or to warm up the soil and air around the plants. It does not hurt to use row cover to speed things along and to keep out the flea beetles.
Broccoli - seed a small amount directly into garden beds, or buy transplants up to mid-August. If you are direct seeding into a garden bed, remember to thin or prick out and replant the broccoli babies so that they have proper spacing (15” or so).
Cabbage - same as broccoli. Choose shorter day varieties. Seed packets usually list the days to maturity for all crops. In early August, you can usually get away with planting a 60 day cabbage that will be ready in early October.
Kale - this is a great time to put in a few more kale plants or seeds, they will size up before snow flies, and will withstand lots of wintery weather. The good thing about kale, is that once it is full grown, it will just stand around in the garden waiting to be picked. It does not get “too old” or bolt (jump into seed production mode). This makes it a great early winter crop and a joy to harvest under snow fall. Collards can be treated this way as well.
Arugula - a nice addition to salads, this tender green with a mustard-like flavor is also a great survivor of cold temperatures. It can withstand many hard frosts and will continue to add a little spike to your salads well into November and December. You can put row cover on it to keep away the flea beetles and to give it a little extra protection from cold winds that can dry it out. If it starts to turn a little purple in the colder temps, don’t worry about it, it is still fine to eat. This is just a symptom of not being able to absorb phosphorous in cold conditions.
Turnips - a short season salad turnip can still be sown in August. I like the Hakurei variety from Johnny’s. It is delicious raw in salads, sliced thinly or finely diced, or sauteed in a little butter with fresh herbs (winter savory makes a special appearance at my house, often in this dish in particular). People who think they hate turnips will just be shocked when they taste these buttery slices that just melt in your mouth.
Spinach - in the first half of August, it is a good idea to plant a large patch of spinach. It will germinate in the cooler night time temperatures (spinach does not like to germinate in the heat) and will last a long time in the field in the cool temperatures of October and early November.
Carrots - fall carrots are best seeded right around July 4th. This gives you a chance to do an early batch of carrots for late spring, early summer eating, and then a second (or third) batch for fall eating. Fall carrots are considerable sweeter than spring seeded carrots and are definitely worth the trouble.
Boc Choi - this is another crop that does really well in the cooler temperatures of fall. It is not a heat lover, and therefore should only be planted in April and May and then again in mid to late August for fall harvest. This benefits from row cover if you have a lot of flea beetle pressure. There are quite a few different versions of boc choi, and if you like the crunchy texture and delicate flavor of this crucifer, then please consider trying baby boc choi, red boc choi, or full sized boc choi. While it is easier to start with plants, it is certainly possible to direct seed this crop.
Beets - fall time beets are sweet, tender, and do not have that “dirt” taste of beets grown in full summer heat. Last planting date for fall beets is around August 10th. They should be direct seeded in the garden and then thinned to one plant per 2 to 3 inches. You can space the rows 10 to 12 inches apart and fit about 3 rows in an average bed with a 4 ft width. The greens are tasty too, and the little delicate plants you pull out when thinning are a great addition to sauteed greens, soups, or even salads if very young.
Cilantro and Dill - these herbs can be planted directly in the garden from seed as late as mid-August. They grow well in the cold, and actually prefer it. The cold slows them down and prevents them from going to seed. Plant a good sized patch since you can harvest the plants well into December. They can take a frost, a snow fall and still will bounce right back.
Mustard Greens - these can be planted just like arugula. See instructions above.
Radishes - are a great addition to the late season garden. They can be planted right up to early September, and will maintain a high level of quality right up until it snows.
Lettuce - you can direct seed certain varieties of lettuce for fall harvest. Some do better than others in the cold. I like to plant Merveilles des Quatres Saisons and Tango for their beauty, taste, and cold hardiness.
Parsley - this herb can take very cold temperatures, so make sure, in mid-July or so that you have a nice patch of this going into fall and later summer. If this is an herb that you use frequently, it does not hurt to plant two or three different patches over the course of later April to mid - July. It is a slow grower, so after mid-July you can only plant it from transplants, not seed.
