Onions, Shallots & Garlic

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 the 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.
