I’ve written a lot about the perennial “weeds” around my place that keep me in greens, but there are also some veggies that aren’t known as perennials but can be managed that way for good eating with very little work.
Surprisingly, garlic can be managed that way. I plant a lot of garlic because I use huge amounts as green garlic before it ever matures a bulb. In one area I forgot to harvest, and by year three I had a thick clump of fine grassy leaves in the spring that were tender and delicately scented of garlic. Of course you won’t get any bulbs if you manage garlic this way. It’s strictly a leafy herb. In early spring I start cutting bunches of the leaves thinly, like chives, to float on soups and toss decoratively on top of other dishes. By late spring the leaves are tougher and I use handfuls of them chopped into stir-fries where they will get at least a few minutes of cooking. In midsummer the leaves brown and die back, and new leaves come up in the fall.
I’m also experimenting with managing ordinary leeks in a perennial bed. So far I’ve only been at this for a couple of years, so I don’t know how it will work out in the long run. The first year I planted deeply in the normal way, then when I was ready to harvest the leeks in late summer, I carefully dug away the dirt next to them and cut the edible shaft off, leaving the base and roots in place. Naturally you get a bit of dirt on the cut and have to trim away another 1/4 inch to clean them up for the kitchen. The following spring each base sent up between 2 and 5 “daughters.” I dug some out by the roots to thin the bed, using the thinnings chopped up in greens dishes. I left some by themselves and some as smaller clumps of two or three.
At this point in late spring all are of useable size, although of course the singletons are larger. I’ll harvest some as described above and leave some in place to throw up a bloomscape. Leek scapes are one of my favorite garden treats. The tough outer skin needs to be peeled off but the interior is delicious, sweet, crisp, and gently oniony. It’s a wonderful element in Chinese dishes, having both flavor and texture.
I’ll plan to dig out enough by the roots to leave just one base in each planting position, so that (I hope) each will again make good-sized useable leeks the following year.
Keep in mind that your own leeks, harvested young, can often be used up to the tips. Cut the leaves in cross sections about 1/4” wide and use in cooked greens dishes or stew them gently in butter or olive oil with a little salt until tender. They need cooking to get tender even in early spring, and get tougher as the weather warms and are no longer useable except to cook in broth for flavoring. Don’t try cooking the leaves of leeks from the store, which have been in storage and are tough as nails.
When managing anything as a perennial, don’t forget to keep the soil fed. I sprinkle some chicken manure around in fall, then mulch with alfalfa hay, and the soil is black and rich now, a far remove from the tan adobe clay that I started with.
