Choosing the Right Garlic for Containers

Softneck Garlic

• Stores longer (6–9 months).
• Grows well in a variety of climates.
• Great for braiding after harvest.

Hardneck Garlic

• Stronger flavour.
• Produces edible flower stalks called scapes.
• Slightly shorter storage life (3–5 months).

Tip for beginners: Choose reliable varieties like Solent Wight (softneck) or Carcassonne Wight (hardneck). Avoid supermarket bulbs, which may carry disease and are often unsuited to UK growing conditions.

Caring for Garlic in Containers

Watering

Feeding

Protection
