This is another episode in my monthly series of 14 Workhorse Crops. These crops are reliable under a wide range of conditions. We’re several months into this series, so here’s the complete list: asparagus, beans, cabbage, carrots, chard, collards/kale, garlic, potatoes, sweet corn, sweet potatoes, tomatoes, watermelons, winter squash, zucchini/summer squash.
I hope to help you become more efficient, productive and profitable (if selling) as you deal with another strange year. Maybe you are not at home as much as last year, or maybe your helpers have gone back to school, but you deeply appreciate sustainably grown food. You still want to garden, even with less time at home. You can use the search box to find previous month’s entries, such as September.
Workhorse Crops to Plant in October
In October in central Virginia we only have enough remaining good growing conditions outdoors to plant 3 of our 14 Workhorse crops – we can still transplant chard, collards and kale. A big step down from last month’s 8. We could also plant some garlic scallions (the soil is still too warm for us to plant garlic, but if you are in a colder zone than us, you’ll want to see this post.)
In October here, outdoor gardening is more focused on harvesting and less on planting. In contrast, October is our busiest planting month in the hoophouse! In September we direct sowed our first hoophouse bed, and sowed other crops in an outdoor nursery seedbed. Two to four weeks later, in October, we transplant them in the hoophouse. Workhorse crops getting transplanted into our hoophouse in October include Red and White Russian Kales, Bright Lights chard, and Napa Chinese cabbage. This year we are trying some carrots (actually we sowed those in September). We have plenty of other crops that don’t qualify as workhorses too!
Swiss chard can be sown outdoors here in September, and transplanted early in October for an early winter harvest, with the option of overwintering under rowcover to provide harvests during the winter. We could direct sow chard in September and protect it for the winter, for a late winter and early spring harvest. Remember that red chard is more cold-hardy than the multi-colored types, and green chards tend to be even more hardy.
For hoophouse winter harvest, we sow Bright Lights chard in our nursery seedbed September 15 and transplant it October 16. We love the beauty of the multi-colored chard mixes, both growing and after harvest, and we have found that the hoophouse protects the crop well enough that it does not die, even without inner rowcover (unless the outdoor temperature is forecast to be below 8°F (-13°C).
This is rather late for us to transplant collards outdoors, but if we need to, and we have some good thick rowcover, we’ll do it. The extra warmth of the rowcover will help it make up for lost time.
Our last date for sowing Vates kale outdoors is 10/30. We can still transplant August-sown kale to fill gaps if we need to – see August’s post. Because kale makes some growth whenever the temperature is above about 40°F (5°C), it is a valuable winter crop. Our sunnier winter days are often warm enough for kale (and spinach!) to make some growth. We will sow more kale in late January, to give us a spring crop.
In the hoophouse we grow both the White Russian and the slightly smaller Red Russian kale. See the explanation about the merits of Oleracea and Napus kales. We make sure to transplant the shorter red kale on the south side of the bed, so it gets adequate light, with the white kale on the north. You may have noticed that red and purple-leaved vegetables grow slower and tend to be smaller than their green cousins. This is because they have less green! Green leaves are needed for photosynthesis, which enables plants to grow. Green plants also contain the reds and purples, but the green dominates. This is similar to the conundrum of red and orange fall leaves – where do those colors come from? They are there all along, but are masked by the green. In preparation for leaf fall, the trees absorb all the green chlorophyll, leaving the fall colors visible.
Garlic scallions are immature garlic plants, mostly leaves, pulled up before they make bulbs. They are the garlic equivalent of onion scallions (bunching onions, spring onions, escallions). Great for omelets, stir-fries, pesto, soups, and many other dishes.
We plant ours using the culled tiny cloves from the bulbs we save for outdoor garlic planting in early November. Tiny cloves will never produce big bulbs, so growing garlic scallions makes very good use of them! Planting garlic scallions is simplicity itself! Plant the small cloves close together in closely-spaced furrows, simply dropping the cloves in almost shoulder to shoulder, any way up that they fall. Close the furrow and mulch over the top with spoiled hay or straw.
You could plant these next to your main garlic patch, or in a part of the garden that’s easily accessible for harvest in spring. We plant our small cloves for scallions at one edge of the garden, and as we harvest, we use the weed-free area revealed to sow the lettuce seedlings for that week.
If you want to have Garlic Scallions to eat or sell in early spring, when new fresh vegetables are in short supply, and homesteaders may be running out of stored bulb onions, see my post Alliums for March. With a last frost date of 20–30 April, we harvest garlic scallions March 10 to April 30 in central Virginia, or even into May, if our supply lasts out, and we don’t need the space for something else. Harvesting is simple, although depending on your soil, you may need to loosen the plants with a fork rather than just pulling. Trim the roots, rinse, bundle, set in a small bucket with a little water, and you’re done!
Rather than dig up whole garlic scallion plants, some people cut the greens at 10″ (25 cm) tall and bunch them, allowing cuts to be made every two or three weeks. We tried this, but prefer to simply lift the whole plant once it reaches about 7″–8″ (18–20 cm). The leaves keep in better condition if still attached to the clove. Scallions can be sold in small bunches of three to six depending on size. A little goes a long way! If you do have more than you can sell in the spring, you could chop and dry them, or make pesto for sale later in the year.
You can plant garlic scallions at other times of year, if you have planting material. See Plant garlic scallions from softneck varieties (Alliums for February). If you plant in a hoophouse, more of the year opens up as a planting season. You can plant whole bulbs (the small cull ones you can’t sell, or don’t want to peel) and grow your garlic scallions already in a clump, rather than in rows of plants.
Some growers find they make more money from garlic scallions than from bulb garlic, partly because they don’t have the costs of curing and drying the bulbs! I encourage you to experiment with planting a few cloves at different times of year and record your results. Because you do not need to work with the right times for bulbing and drying down, all sorts of dates are possible!
Napa Chinese cabbage
Maybe you think I’m stretching things to classify Napa Chinese cabbage as a workhorse, but in my defense, I’ll say firstly that success in farming involves creativity and flexibility, and secondly that the Asian greens as a category are genuine Hoophouse Workhorses, as they grow so well in cool temperatures and short days. It is a cabbage! We sow Blues (53d from transplanting in mild weather) in a nursery seedbed on September 15 and transplant in the hoophouse October 2, at only two weeks old (very fast-growing in September). Because this is a heading vegetable, we leave it to grow to full size before harvesting. That will be in January. Many of the Asian Greens are harvested by the leaf, but Napa cabbage and pak choy are more often cut as a head.
Workhorse Crops to Harvest in October
Eleven of our 14 workhorse crops can be harvested in October (also true in September and August, but with substitutions!) No asparagus, no garlic, no more watermelon. Depending when the frost bites, there will be several fewer harvest options by the end of October.
Beans can be harvested until the weather gets too cold. We have covered the beds with rowcover to keep the plants warmer and growing faster. It’s true that pollinating insects can’t get at the flowers to perform their pollination services and make more beans, etc. But that doesn’t matter. We are more interested in fattening up the already pollinated beans! It’s also true that the yields are now way down, so we need to balance the benefits against the costs. Sometimes it is better to clear the crop (and its pests and diseases) and sow a cover crop.
Cabbage We harvest fall planted cabbage from September 25. We like Early Jersey Wakefield (45 days from transplanting) and Farao (64d) for fast-maturing cabbage; Melissa Savoy 85d; Early Flat Dutch 85d, Kaitlin 94d, for storage cabbage which are slower-growing. We have also liked huge Tribute 103d, Tendersweet (71d) for immediate fall use, and Wakamine (70d). Deadon (105d winter cabbage) is extremely cold hardy – we leave it outdoors until nights threaten to hit 10°F (-12°C) . Double-check those days to maturity, I may have mixed days from transplanting with days from sowing.
Carrots: If we sowed carrots in July, we will be harvesting in October.
Chard can be harvested whenever you want some. This year our chard did extremely well all summer and we are bored silly with it! We wish we had had stored cabbage, or some fall broccoli. We are relishing our fall senposai!
The outdoor killing temperature for unprotected Bright Lights chard is 22°F (–6°C); red chard survives down to 15°F (–9.5°C) and green chard to 10°F (–12°C).
Collards can be harvested in October.
Kale can be lightly harvested, if our early August sowings came through.
Potatoes: We can plant potatoes between mid-March and mid-June, leading to harvests in July-October. Protect potatoes from frost when harvesting. Read more about potato harvest here.
Our March-planted potatoes are in the root cellar. We’ve been eating those since July. We often plan to grow more in the June planting than the March planting, as root cellar storage over the summer is more challenging for us than having them in the ground.
Sweet Corn harvest is still going, thanks to our sixth sowing on July 16.
Sweet potatoes need harvesting in October here, before it gets too cold. Usually sweet potatoes are harvested the week the first frost typically occurs. I wrote a lot about this topic here. I wrote all the harvesting details in another post, 10/12/20.
Contrary to myth, there is no toxin that moves from frozen leaves down into the roots. On the other hand, below 55°F (13°C), they’ll get chilling injury, which can ruin the crop. Roots without leaf cover after a frost are exposed to cold air temperatures, and have lost their method of pulling water up out of the soil. I remember one awful year when we left the sweet potatoes in the ground too late, hoping they’d fatten up a bit to make up for a poor growing season. Instead, the weather got cold and wet, and the sweet potatoes were rotting in the ground (it was November by then), and those that didn’t rot got chilling damage that prevented them ever softening in cooking. Sweet potatoes that stay hard are no fun to eat!
Tomatoes are winding down. If a frost threatens we will harvest them all, including the green ones. I prefer to store them on egg trays or in shallow crates, to gradually ripen indoors. But other people prefer fried green tomatoes. To my taste buds, it could be cardboard inside the batter! I don’t know the nutrient content of fried green tomatoes, but I feel certain ripened tomatoes without batter are more nutritious!
Winter Squash harvest continues once a week throughout September and October. Stored winter squash can provide meals all winter and also in early spring when other crops are scarce. We used to harvest as late as possible in the fall, but now we prioritize getting a good cover crop established, to replenish and protect the soil, so we have a Grand Finale harvest just before Halloween, when we harvest all the large interesting almost-ripe squash, and give them away for lantern carving. Some go to the chickens too. Harvest before the fruits get frosted, which is shown by a water-soaked appearance of the skin.
Zucchini and summer squash are now being harvested every other day. Our last sowing was August 5. We harvest beyond the first fall frost, by covering that last planting with rowcover on chilly nights. But once it gets cooler, they grow slower, and are not worth checking every day.
From storage: spring cabbage, carrots, garlic and potatoes, winter squash.
Food processing is still busy.
Workhorse Crops Special Topic
September 17 is our last chance to sow oats as a cover crop. If sown later they will not reach a good size before they are killed by cold temperatures. The soil would not be held together well. It would be better in those circumstances to mow the weeds and leave their roots to hold the soil together over the winter.
Oats winter-kill in most of zone 7 or colder, and survive in zone 8 or warmer. The end for oats is around 10°F (-12°C), depending on their size and the frequency of cold temperatures. Large oat plants winter-kill after 3 days at 20°F (-7°C) or colder. Young oats are tolerant to temperatures down to 12°F (-11°C), until the 5 leaf stage, as the growing point is still underground. Once the plant starts to make noticeable vertical growth and form nodes (22-36 days after planting, depending on variety, sowing date, and water), oats can die at 24°F (-4°C).
Dead oats leave an easy-to-work surface for early spring vegetables.
Clovers can be sown here throughout September, as can winter wheat and winter barley. Winter rye can be sown here in September (not August – it could head up!). Hardy Austrian winter peas can be sown in late September with rye.
