Pick tips, do not pull plants
The instinct with a leafy green is to pull the whole plant, and it is the wrong instinct here. Garland chrysanthemum regrows readily from the leaf joints left behind, so a plant harvested by the tips keeps producing for weeks while a plant pulled up is simply over. Three or four plants picked properly will outyield a dozen pulled, and the later cuts are the ones with the best texture.
Cut the top three to four inches (8 to 10 cm) of each shoot, taking the cut just above a pair of leaves so that the buds sitting in those leaf joints can break and grow away. Leave at least two sets of leaves on the stump. If you cut below the lowest leaves you have taken the plant's ability to regrow along with the harvest.
Use scissors or a sharp knife rather than snapping the stems. The stems are hollow and brittle, and a torn stem often splits down several inches, which lets rot into the stump and kills the shoot you were counting on.
| Where you cut | What happens next | Verdict |
|---|---|---|
| Top 3 to 4 in (8 to 10 cm), above a leaf pair | Two or three side shoots break within two weeks | Best; repeat every two to three weeks |
| Halfway down the stem | Regrows, but slowly and with thicker stems | Use only for a final heavy cut |
| At soil level | Sometimes resprouts from the base, often does not | Only when clearing the row |
| Pulled up whole | Nothing; the plant is finished | Only for thinnings |
Time it by the buds, not by the size
Size tells you when you may pick. Flower buds tell you when you must. Leaves are at their best when the shoots are soft enough to snap between finger and thumb without any string, which is generally when the plant stands eight to ten inches (20 to 25 cm) tall. Past that, the stems firm up and the flavor deepens quickly.
The change once flower buds form is not subtle. The aroma turns sharp and medicinal, the leaves narrow and toughen, and the stems become genuinely fibrous. This is not a crop where you can leave the harvest a fortnight and accept slightly coarser leaves. Check the growing points every few days once the weather warms, and cut everything usable the moment you find the first tight green bud anywhere in the row.
| Stage | How it looks | How it eats |
|---|---|---|
| Thinnings, 2 to 3 in (5 to 8 cm) | Whole seedlings, soft stems | Mildest of all; use raw |
| Young tips, 8 to 10 in (20 to 25 cm) plants | Wide soft leaves, stems snap cleanly | The crop you are aiming for |
| Mature shoots, before bud | Darker, narrower leaves, firmer stems | Still good cooked; strip the lowest leaves |
| Bud showing | Tight green knots at the shoot tips | Harsh and stringy; cut the row and move on |
How many cuts you actually get
An autumn sowing picked properly will usually give four or five cuts before it tires, spread over two to three months. A spring sowing gives two or three at best, because the plants bud up while they still have plenty of growth in them. Knowing which crop you are managing changes how greedy you should be with each cut.
- First cut Take the pinched tip only, leaving the side shoots. This is a small harvest and it doubles the size of every one that follows.
- Second and third cuts Take the top three or four inches of each side shoot, two or three weeks apart. Water and give a half-strength liquid feed the same day.
- Fourth cut onwards Expect shorter, thinner shoots and a stronger flavor. Cut a little deeper each time, but always above a leaf pair.
- Final cut When regrowth slows to a crawl or the first buds appear, cut everything back hard, use it all, and either resow or let a few plants run to flower.
Harvest in the cool of the morning if you can. Shoots cut in afternoon heat go limp within the hour and never crisp up properly, however long you stand them in water.
After picking, and what to record
The cut shoots wilt fast because the stems are hollow and lose water quickly. Stand them upright in an inch of water for half an hour, then wrap them loosely in a damp cloth and refrigerate; handled that way they hold for three or four days. Do not seal them in a closed bag while warm, which turns them to slime overnight. Wash immediately before use rather than before storing.
Record the date of each cut and roughly how much you took, plus the position of the row. Over two seasons this gives you the number that matters most for planning: the real gap between cuts in your own conditions, and the total number of cuts an autumn row gives compared with a spring one. Note the date of the last useful cut too, because that date, counted back from your first flower buds, tells you exactly how late you can still sow and expect a worthwhile crop.
