Marshall’s has an extensive range of onion, garlic, and shallot sets which have been tried and tested to select the best performing varieties. You can grow onions, garlic, and shallots from seed or from sets.

Sets are easy to grow as they can be planted directly into enriched soil in your garden, or into wide containers, as they’re low-maintenance and don’t take up much room. Onion, garlic, and shallot sets can be planted in the spring as the soil starts to warm. They should be harvested from late June or early July, as the leaves begin to turn yellow.
