Because the plant is an evergreen perennial there is no sowing-to-clearing arc and no dead period. There is a crown in the ground that grows hard in spring, tries to flower in early summer, is stopped from flowering, flushes again in autumn, and then ticks over slowly through winter still producing pickable leaves. Seen that way, the jobs are few and each one has an obvious trigger.
The pivot of the year is the first flower stem in late spring. Everything before it is easy picking of the best leaves of the season. Everything after it is a matter of keeping the plant vegetative by cutting stems out weekly. Gardeners who lose their salad burnet to bitterness by midsummer have almost always simply missed that pivot by a fortnight.
The second thing that shapes the year is winter picking. This is one of very few herbs that gives you fresh green leaves in cold weather, so autumn preparation is not about putting the plant to bed, it is about setting it up to crop through the cold months.
| Season | Main job | Also worth doing |
|---|---|---|
| Late winter | Clear debris off the crowns, strip dead outer leaves | Light compost top-dressing around, not on, the crown |
| Early spring | Divide old woody clumps; sow new seed | First proper picking as the rosette fills out |
| Mid spring | Pick heavily; leaves are at their best | Thin seedlings, lift and move volunteers |
| Late spring | Begin weekly flower-stem removal | Watch for slug damage on soft new growth |
| Early summer | Keep cutting stems; hard cut-back if coarse | Water deeply in dry spells; no feeding |
| Midsummer | Hard cut-back and water; do not sow | Leave a few heads on one plant if you want seed |
| Late summer | Sow for next year, or divide in mild areas | Collect and dry saved seed |
| Autumn | Pick the autumn flush; clear leaf litter off crowns | Stop any feeding; do not mulch over the crown |
| Winter | Pick lightly, a few central leaves per plant | Review notes, plan spring divisions |
Late winter into spring: the best leaves of the year
Start by clearing. Rake off fallen leaves and any debris sitting on the crowns, and strip away the dead and battered outer growth from each rosette. This does three jobs at once: it removes slug shelter, it stops wet sitting against the crown, and it lets light into the center where the new growth is about to come.
Salad burnet starts moving as soon as soil temperatures reach the low forties Fahrenheit (around 5 to 7C), weeks ahead of anything you sow. Top-dress lightly with garden compost around the crown, never over it, and then leave the feeding alone for the rest of the year. Begin picking once the center of the rosette is producing new leaves freely.
Early spring is also the main division window. Any clump three or more years old with a bare woody middle should be lifted, split into fist-sized pieces and replanted. It is the main sowing window too, into cool soil at 50 to 70F (10 to 21C), and the point at which self-sown seedlings are big enough to recognize and small enough to move without checking.
Late spring through summer: the flower-stem season
From late spring the plant starts throwing tall wiry stems topped with rounded green heads, and everything now depends on your response. Walk the plants once a week and cut every stem out flush with the crown. Cutting halfway is no use; the stem branches lower and comes again. Miss two weeks in warm weather and the plant commits to flowering, the center stops producing and the whole crop toughens.
In midsummer, do the hard reset whether or not the plant looks like it needs one. Cut everything to an inch (2.5 cm) above the crown, clear the material away, and water thoroughly. Two to three weeks later you have a complete rosette of tender leaves and the plant is firmly back in vegetative growth. Doing this on purpose in early or midsummer is far better than waiting until the crop has already gone bitter.
Water only in a genuine drought, and then deeply, about a gallon (4 L) per plant every week to ten days. Do not feed. Do not sow. If you want seed or volunteers, this is the point to choose one plant at the back of the group and leave two or three heads on it while cutting every stem off all the others.
- Weekly stem patrol from late spring Once a week, cut every flower stem flush with the crown. A minute per plant, and it decides leaf quality for the rest of the season.
- Midsummer hard cut-back Cut all growth to an inch (2.5 cm) above the crown, clear the debris and water. Expect a full flush of tender leaves in two to three weeks.
- Deep water in drought only A gallon (4 L) per plant every week to ten days in a dry spell. Daily sprinkling keeps roots shallow and undoes the plant's drought tolerance.
- Late-summer sowing or division Once the heat breaks, sow seed into cool soil, or in mild areas divide old clumps so they have six weeks to root before hard frost.
Autumn and winter: the season that makes it worth growing
Cooler weather brings a second flush that is nearly as good as the spring one, so pick freely through autumn. Then, before the weather turns properly cold, do the one piece of preparation the plant needs: clear fallen leaves off every crown and strip the dead outer growth away so the center is open and dry. Stop feeding by early autumn so growth hardens off.
Do not cut the plant back for winter and do not mulch over the crown. Salad burnet is evergreen and hardy to about minus 20F (minus 29C), and its whole value is that it keeps its leaves through frost and snow when nothing else in the garden does. A plant cut down in autumn has thrown away the only crop you cannot get anywhere else.
Winter picking is light picking. Growth is slow, so take a few central leaves from each of several plants rather than stripping one, and expect a milder, gentler flavor than in summer. Check after heavy rain or thaw that no crown is sitting in standing water, since winter wet, not winter cold, is what kills this plant.
Keep four dates each year: the first proper spring pick, the first flower stem, the midsummer cut-back, and the last autumn clear-up. They repeat closely from season to season, and from those four you can write the following year's whole schedule, including when the weekly stem patrol has to start.
