Plant Australian Purple Garlic in full sun with loose, well-drained soil. Avoid heavy, wet ground, as garlic bulbs can rot if they sit in water for too long.
Best Soil for Growing Garlic
- Garlic prefers fertile soil with good structure.
- Improve the area before planting rather than trying to fix poor soil later.
- Heavy clay should be improved or mounded.
How to Plant Australian Purple Garlic Cloves
Step-by-step:
- Break the bulb into individual cloves just before planting.
- Keep the papery skin on each clove.
- Plant the largest, healthiest cloves.
- Place each clove pointy end up.
- Plant around 3–5 cm deep.
- Space cloves 10–15 cm apart.
- Water in after planting.
To plant Australian Purple Garlic, separate the bulb into cloves and plant each clove pointy end up, around 3–5 cm deep and 10–15 cm apart. Water in well after planting.
Growing Australian Purple Garlic in Pots
Australian Purple Garlic can be grown in pots as long as the container is deep enough, drains well and receives full sun. Use a quality potting mix and avoid letting the pot dry out completely during active growth.
Watering Garlic
Garlic needs steady moisture while growing, especially during bulb development. Keep the soil lightly moist but never waterlogged, then reduce watering as the leaves begin to yellow near harvest time.
Feeding Australian Purple Garlic
Feed Australian Purple Garlic during active growth with a balanced fertiliser or liquid feed. Avoid heavy nitrogen late in the season, as this can encourage leaf growth instead of good bulb formation.
Mulching Garlic
- Light mulch can help retain moisture
- Useful in dry or windy areas
- Keep mulch loose
- Avoid smothering young shoots
- In very wet climates, use mulch carefully to avoid holding too much moisture
