This is the first of my planned posts on successful crops I’m going to revisit in the demo garden next year. I thought I’d start with what seems fundamental: root crops.
They’re successful because, for the most part, they are easy; although, as Bob’s last post showed, they can have pests, both below ground and above. However, given good soil, plenty of water and some attention, they usually thrive.
We will certainly be growing potatoes and sweet potatoes, but I won’t discuss those here. Nor will I mention root crops I’ve struggled with, like parsnips. Which of this category of plants will I definitely be growing? Beets, carrots, turnips, onions, radishes, and (the odd one out) celeriac.
Beets are one of my favorite vegetables… okay, I know, some of you don’t like beets. I suspect that this is mostly because of what happens to them when they’re canned, so please do try them fresh; you’re allowed to still not like them afterwards! I will eat your share. They’re tasty and easy to grow: you need a nice loose soil with good fertility, and you need to water them, but they have few pest problems (except rabbits and the like) so usually the greens end up looking good enough to eat – and please do! The varieties I have most fun with are Bull’s Blood (for the spectacular deep red leaves as well as the roots), Chioggia (for the bull’s eye red-and-white striped interior), and golden (Burpee’s Golden and others) as shown above. These have a nice mild flavor and the advantage of not staining everything in their vicinity pink.
Carrots are a bit more of a challenge to grow, but I’ve had great success at the demo garden with them, probably because of our great soil. Carrots need deep, loose soil – not the clay we generally have around here before adding amendments – but at the same time you don’t want to overdo the fertility, because too much nitrogen causes the roots to grow lots of hairs, or even to do this –>
I had great luck with Cosmic Purple carrots this year – I forgot to harvest them from a spring sowing until mid-July, and they were still tender and delicious, plus they look beautiful with purple skin over an orange and yellow core – so I will probably do those again, and maybe some other colors too. I may also try a row of little round Paris Market-type carrots in a salad table. The round kinds are good for gardeners who have not yet achieved the perfect soil. Try amending with coarse sand as well as peat moss or coir and not too much compost to fix your soil for longer carrot-shaped carrots.
One curious incident in the world of carrots happened to me this year: a flower. Carrots are biennials; they’d prefer to grow leaves and tasty roots in their first year from sowing, and flowers and seeds in the second year. We usually interrupt this cycle by harvesting the plant to eat, but if you are planning to save seed from carrots, you need to let them winter over and bolt up into flower the next spring. This carrot decided, in July, that it had already had a winter’s rest, and needed to make seeds right away. I’m sorry to say I didn’t let it get that far (I needed to plant something else there) but I did leave the flower for a while to bemuse gardeners and provide tiny insects with a drink of nectar.
Carrots can also be planted in the late summer/early fall for fall or winter harvesting. Mm.
Turnips have a few root pests and also get hit in the leaves by harlequin bugs, cabbage loopers, and other Brassicaceae pests, so whether planting in spring or fall I usually start them under row cover and keep them there until they get too tall. Turnip greens are great for adding bitterness to a saute of mixed greens, but it’s tough to keep them looking good while growing organically. I have only grown Purple-Top White Globe, which is a reliable standard, but I’d like to branch out into some of the little white or red-skinned types.
There’s a whole world of onions out there to try. I plan to grow a lot of them throughout the garden next year, mostly started from sets (because they are easy) but I’ll also do some smaller ones from seed (Cipollini onions, cute little flattened disks, can be started right in the ground in spring for summer harvest). Onions can have pests, but I have never had a serious problem with them (aside from the occasional rotted one) and I know the rich soil in the demo garden treats them well.
Let’s grow radishes in every color – yellow and black as well as the more common pink, red, purple and white. Fast and easy and a great addition to salads or (especially the longer Daikon radishes) to stir-fries. The leaves can go into that sauteed mixed greens dish – spicy! Brassicaceae pests do damage the leaves, but harvest comes so quickly it usually doesn’t matter much.
Celeriac is pretty much the opposite – it needs a place in the garden to mature over a long season, but I’ll give it one because it’s such a rewarding plant and the leaves are just as edible as the roots.
And that concludes my tour of root vegetables you’ll (most likely) see in our demo garden next year! Don’t forget that you can learn more about growing most of these crops (we seem to have left out celeriac, so far) at the Vegetable Profiles link on the Grow It Eat It website.
Root crops are magical and fun and good additions to your menu as well as your garden! Try some!
