Bed MemoryAllium family vegetables
The alliums, or onion family, are onion, garlic, leek, shallot, scallion and chives.
For crop rotation they count as one crop: garlic should not go where onions grew in either of the last 2 years. Check a bed below.

Rotating alliums
Onions and garlic share soil-borne problems such as white rot and onion maggots, so they move together. Perennial chives can stay put; rotate the annual crops.
A worked example
You plant garlic each October. The front bed grew onions in 2026, so this fall's garlic should go in a bed that had no onion family crop in 2025 or 2026.
Questions gardeners ask next
Are garlic and onions the same family?
Yes. Garlic, onion, leek, shallot and chives are all alliums.
Can I plant garlic where garlic grew last year?
Rotation guides advise moving it, ideally for 3 years or more, so problems in the soil do not build up.
What follows garlic?
Garlic comes out in early summer in most of the US, so a summer crop from another family, such as beans or squash, can follow the same year.
