Helen’s guide to growing garlic

 

Helen Simpson, from the Mushroom Shed, tells you all you need to know about growing garlic. She has also written articles about growing basil, brassicas, chilli, coriander, cucurbits, ginger & turmeric, mint, raspberries, rhubarb, strawberries, tomatoes and lesser known herbs.

garlicWith wintery weather underway, it can be difficult to find something cold hardy to plant in the veggie patch. But garlic loves the cold weather. In fact the more it receives, the better, as the cold is essential for large bulb formation.

Garlic can be planted in Melbourne from early April to late June. Surprisingly it’s a perennial, but usually grown as an annual and harvested from late November into December.

The downside of growing garlic is it takes up space in the veggie patch for around six to seven months. However its advantages include being relatively free from pests and (as long as it’s kept well-weeded and receives reasonable rainfall) pretty much fuss free. Of course it tastes great!

Selection

There are many varieties, categorised as ‘hardneck’ (firmer tuft above the garlic bulb) or ‘softneck’ (softer tuft, milder flavour, longer storage). We have found the hardneck varieties easier to grow and less prone to rot, but suggest you try both.

To obtain garlic for planting, purchase garlic bulbs from reputable suppliers who haven’t treated the garlic with growth retardants and chemicals. Farmers’ markets offer good choice and supply and you can check with the farmer directly on these aspects. Alternatively, garlic can be purchased in punnets, giving you the advantage of having someone else start the growing process for you.

If you have purchased bulbs, separate the bulb into individual cloves. Only plant the large, outside cloves – keep the small ones for eating. Large cloves produce large garlic – don’t waste your time with the small ones.

Planting

Plant cloves pointy end up, just under the soil. Mulch with a 3cm layer of straw or equivalent – make sure the straw is loose, so the green garlic tops can push their way through when growing. Plant in the sunniest spot you have.

Pests

Garlic is generally a ‘pest free’ crop. However, if you grow a large amount, watch out for the cockatoos in the early stages, who can destructively rip them out of the ground. If this is a problem, place a net over the garlic for the first few months.

Maintenance

Keep weed free!! This usually means weeding two to three times over the growing period. If grown in good soil at initial planting, extra fertilisation is not usually necessary; however, if the green tops of the garlic start to look yellow, fertilise with a liquid fertiliser.

Generally it rains sufficiently over winter to eliminate any need for watering; however, if the ground gets dry, then water.

Harvesting and drying

Garlic is usually ready to harvest around end of November to early December. When the green tops have died back by about one third, feel the garlic under the soil to check if distinct bulbs have formed – if so, it’s ready. Don’t wait until the tops have completely died back, or the garlic can often rot. It is easiest to harvest during a dry period – use a fork to gently lever out – don’t pull out by the tops. Don’t be concerned if it’s flowered.

Garlic can be stored by hanging, laying on airy racks above ground, or plaited and hung out of direct sunlight. If you want to make garlic plaits, do this whilst tops are still green – once the tops have dried, it is difficult.

Garlic takes about two weeks to dry; however, if you can’t wait, use it ‘green’, which means it will be very juicy. The garlic tops and flowers can also be used in cooking.

And finally…

Elephant garlic is also great to grow – note this is actually a variety of leek, not a garlic. It can be planted and harvested a few weeks later than garlic. The huge blue flowers look stunning in a cottage garden and the cloves have a milder flavour for eating.

  1. Hi Helen, thanks for your tips – I’m going to give it a go! One question: when preparing the (outside) cloves for planting, should I remove the papery cover and cut off the bottom bit where it attaches to the garlic head?

    • Hi Kerry. Leave the papery cover on the clove for protection. You can leave the bottom bit on too – however sometimes it snaps off which is also OK. The main thing is not to damage the individual clove. Regards, Helen

  2. I accidently put my garlic on the window sill to dry out. It has just started to turn green. It doesn’t smell like garlic; it barely has a smell.The cloves are gigantic. Can I still use them?

    • Hi Heather, if your cloves are gigantic with little smell, you may have elephant garlic (a leek). Some of ours have turned green too. They can still be eaten or planted, as long as the green is not a mould, which should be obvious on inspection. Normal garlic can look like this too. Regards, Helen
