Garlic is traditionally planted in cold weather and harvest in summer ("plant on the shortest day, harvest on the longest"). Plant the cloves (separated from the bulb), point upwards, deep enough to just cover with soil. A fairly tough and easy-growing plant. On better soil with regular watering you will get a better crop. On poorer soil, and forgetting to water them, you will still get some garlic, only not quite so much.

Leave a garlic to go to seed, and you will probably get plenty of self-sown plants the following year.

To keep for later use, dig up and leave to dry out for a day or so after the green shoots die down. To use immediately, pull up a head when you need it, or cut and use the green shoots.

Culinary hints - cooking and eating Garlic

Cut the growing shoots or use the entire young garlic plants as 'garlic greens' in stirfry.

Over the last couple of years I have had really poor garlic crops which I have put down to fusarium rot. I have since read that it is endemic to Australian garlic (shop purchased).Same this year , so I bought some Mexican or Argentinian stock, planted it in April and it grew beautifully, until most of it started to sprout shoots up the middle from the developing cloves. I left it until the middle of July then pulled it all use as soft fresh garlic. Surprisingly about 10% of the plants were fully mature and dried well, also had a very good root system.Too much N2 climate change or just a warm Perth Autumn. My Australian garlic (March) is still struggling away Any other ideas

Perth's climate is the opposite to East Coast - wet winter and dry summer. It says here plant April to June. It takes about 6 mths for garlic to grow. Maybe better to plant May or June - don't over fertilise it. It is variable weather - not climate change. Climate is the weather of 30 years.

Is it late to plant garlic in July in nz subtropical

Where iam at the moment it get verry cold and forsty in the morning I know it.s may be a bit late to plant garlic but will it still be ok to plant it now or preferably when the frost almost over towards modd August i think ingoulburn Unless the cloves are not effected by the frost

For cool/mountain it say plant Apr/May so you are too late. If you plant now the crop may fail. You could try - wouldn't plant too many though.

You could certainly try planting now, the sooner the better because garlic needs to go through the cold to get a decent size to it. The plants are totally unaffected by frosts down to at least -12°C which is what we get here in July. Just for your information, I usually plant garlic late March for a November harvest. In Goulburn you could probably wait until April/May. Good luck with it.

A saying - plant the shortest day of the year and harvest the longest day. 21st June - 21st Dec.

During the garlic growing period. What fertiliser, how often & how much to use, please.
16 Jun 18, Mike L (Australia - sub-tropical climate)
If you started with good rich soil then you don't need to add more fert. Any all round fert will do. 10-14 N 4-8 P 10-14K @ 2-3 teaspoons per 9 L of water. Or use an organic fert at the recommended rate.
