When to Plant Garlic in Tasmania

The good news is that Tasmania offers excellent garlic growing conditions.

Are you looking to grow garlic in Tasmania?

Most varieties grow well here with the exception of subtropical varieties like Glenlarge and Italian Pink.

However, before you source your bulbs and prepare your soil, you need to know when to plant it.

When to plant garlic in Tasmania

The best time to plant garlic in Tasmania is generally in April or May. This is approximately when the soil will get down to 10 degrees Celcius, which is the optimal temperature for garlic cloves to be planted.

Early season varieties may also be planted in March.

Autumn-planted garlic is ready for harvest in late spring or summer, depending on the variety chosen.

Depending on the variety you are growing, you may be able to get away with planting garlic in Tasmania as late as June.

However, remember the optimal time to plant garlic is when the soil temperature drops to 10°C. Cold soil and shorter days can lead to stunted growth.

Can you grow garlic in summer?

Garlic is a cool-weather crop and it would struggle to grow in Tasmania’s summer heat.

If you were to plant garlic in summer, not only would it not grow properly but it might also result in bulbs that don’t separate into individual cloves.

How long does garlic take to grow?

Garlic takes 7 to 9 months to grow and is generally ready for harvesting in spring or summer.

The best time to pull garlic from the ground is when the tops are drying and turning brown. Lower leaves turning yellow or brown is another sign that your garlic is ready for harvest.

How to prepare your soil for garlic

When choosing a place for your garlic, make sure the soil is well-draining and rich in organic matter. Choose the sunniest spot in your garden.

Garlic will thrive in an environment with pH levels between 6-7, so you may want to add lime before planting if your garden soil is acidic.

If you’re growing garlic in a container, make sure it’s free-draining and has plenty of drainage holes.

How deep to plant garlic

Plant garlic cloves 2-3cm deep with the pointy end up. Space cloves 10-15cm apart, and cover with a 5cm layer of mulch. Leave the skin that covers each clove intact.

After planting your garlic cloves, water them well. Keep the soil moist but not soggy for the first few weeks and then watch out for signs of drying out in winter.

If you receive regular rain through winter they should be fine without any more watering, but keep an eye on them and make sure the soil doesn’t dry out completely.

Does garlic need full sun?

For best results, select a spot in your garden that receives at least 6 hours of sunlight per day.

Grow garlic near cabbage, spinach, dill, beets, kale, potatoes, eggplants, tomatoes, peppers and fruit trees.

Types of garlic

Garlic is generally divided into two categories: hardneck and softneck.

  • Hardneck garlic grows clusters of cloves around a central stalk, which becomes woody as the plant matures.
  • Softneck garlic has a rounder bulb without a woody stalk.

The two types both come in several varieties with different flavours, textures and uses.


What can you not plant next to garlic?

Garlic shouldn’t be planted next to asparagus, peas, beans and parsley because it may stunt their growth.

Can you plant a garlic clove that has sprouted?

Yes, you can plant a garlic clove that has sprouted. Just make sure that the cloves are firm and healthy, and always select the biggest ones for planting.
