The calendar for this crop runs opposite to most vegetables. The bulbs go in during autumn, the plant does its growing through the cool months when the beds are otherwise quiet, and it shuts down for summer rather than through winter. That makes it an unusually easy crop to fit into a plot, because it occupies ground precisely when other things do not and asks for almost nothing during the busiest weeks of the year.
Two decisions shape the whole cycle. The first is when to plant, which is governed by soil temperature falling rather than by any date on a calendar. The second is when to lift, which is governed entirely by the tops dying back. Everything else, including hilling and the very small amount of feeding and watering involved, hangs off those two points.
The year in phases
Read the table below as the shape of the year rather than a fixed timetable, and adjust it by watching soil temperature and the state of the tops. The same sequence works in either hemisphere.
| Phase | What the plant is doing | What you do | Decision point |
|---|---|---|---|
| Autumn planting | Rooting from the dormant bulb | Plant six inches (15 cm) apart, tip at the surface | Soil at planting depth below 68F (20C) and falling |
| Late autumn | First tops up, division beginning underground | Weed by hand; water only if the ground is dusty | Green tips showing within two to four weeks |
| Early winter | Steady leaf growth in mild climates | First hilling once tops are six to eight inches (15 to 20 cm) | Clump visibly widening at the base |
| Deep winter | Slow or stalled; tops may die back in cold areas | Mulch loosely in hard-winter areas; otherwise leave alone | Frost heave lifting clumps means firm them back in |
| Early spring | Strong regrowth, clump dividing fast | Weed thoroughly; one light low-nitrogen dressing on poor sand only | Tops lengthening again after winter |
| Mid spring | Bulbs forming and swelling | Second hilling; stop all feeding | Clump full width, tops still fully green |
| Late spring | Bulbs sizing up, reserves moving down | Stop watering entirely; keep the row weeded | First yellow leaf tips appear |
| Early summer | Tops yellow, flop and dry to straw | Lift on a dry day, split, sort, pickle or cook within days | Tops fully down and soil dry |
| Midsummer to late summer | Replanting bulbs dormant in store | Dry replant stock two to three weeks in shade, then store cool and airy | Wait for soil to cool before planting again |
One year or two: a real choice
The standard cycle lifts the crop after a single winter, in the first early summer. Each planted bulb gives roughly ten to fifteen bulbs of a good, even size, plump enough to trim and clean without frustration. That is the right choice if you want bulbs for pickling whole and you value ease of preparation.
Leaving the clumps in the ground for a second year is not neglect and not a mistake. The clump goes dormant through the first summer, wakes with the cooling weather, and divides again through the second cool season. When you lift the following early summer you get thirty or more bulbs from the original one, each noticeably smaller, denser and firmer. Some growers prefer exactly that: small bulbs pickle firmer, keep their crunch longer and are quicker to fill a jar with, at the cost of far more trimming per pound.
If you go for two years, plant more widely at the start, eight to ten inches (20 to 25 cm) apart, and expect to weed the wider bed carefully through the first season. Give the bed nothing over the first summer dormancy: no water, no feed, no cultivation near the clumps. Simply mark the row clearly and leave it alone until the tops reappear in autumn.
| Approach | Bulbs per original planting | Bulb size | Best suited to |
|---|---|---|---|
| Lift after one winter | Ten to fifteen | Larger, even, easy to trim | Pickling whole with minimum preparation |
| Leave two years | Thirty or more | Small, dense, very firm | Growers who want the crispest small bulbs |
| Mixed row, half and half | Both | Both grades in one bed | Deciding which you prefer in your own kitchen |
A mixed row is the sensible first-year experiment. Lift half the bed at the first early summer, leave the other half marked and untouched, and compare the two harvests directly a year apart before committing the whole bed either way.
The records that turn this into your own calendar
Published calendars are approximations; yours is not. Write down the planting date and the soil temperature you planted at, the date green tips broke the surface, the dates of both hillings, the date the first tops yellowed, and the date you lifted. After a single season those points give you a calendar tuned to your own garden and remove nearly all the guesswork from the second year.
Add the numbers next to the dates: bulbs planted, bulbs lifted, bulbs kept back, bulbs lost to rot or sprouting before you could use them. The number lost to sprouting is the one most gardeners underestimate, and it tells you honestly how many clumps you can afford to lift in a single day next time.
Finally, note the bed. Allium rotation depends on knowing where the alliums were three and four years ago, and a small plot changes shape faster than memory keeps up with. A sketch of the plot each autumn, with the row marked on it, is worth more here than any other note you make.
