The guide says Sept - Oct planting - if that isn't your Spring then it won't grow.

How often do we water garlic?

Put your finger in the soil if it is dry below 1 inch, add water.

What about growing elephant garlic in zine 9b? Is it the same as regular garlic?

It's best to plant hardneck garlic in zone 6B from the middle to late October or even early November. The key is you want it to be cold, consistently below 45°, at least every night time. The first freezing encounter triggers garlic to start producing roots and that would determine how healthy and large the plants grow. Keep in mind freezing above ground may not equal freezing below ground. If you plant it in too warm a time, like early October, it may stunt the growth. It may even rot the garlic if it's wet too long. You may be able to accelerate the process by keeping in the refrigerator for a few weeks I'm not even know people who have kept it in the freezer for a few days or longer hopefully triggering root growth. I haven't tried that so I don't know.

I have success in planting from October 1 up until Early Dec….harvesting late May through July. Nice large bulbs in Zone 7b, getting close to 8a.

Hi, thank you for your comment. What type of garlic do you grow? Can you send me some advise on how you grow it including fertilizers that you use etc? I am growing in zone 8a. Thank you so much, Miriam.

Hey Miriam I'm in zone 8A and I grow Purple Glazer, Italian Mountain Red and Inchelium Red in my raised garden beds. I plant anytime from 10/15 until Halloween. I havent used fertilizer in the past so I cant comment on that. However if you live in SC, Clemson Coop Esxtension has a great site for information on growing all sorts of veggies. I usually start harvesting late May till Mid June (my neighbor said to harvest when half of the leaves have turned yellow/brown. Hope this helps and good luck with growing garlic for next year

This is a transcript of a article on growing garlic in central Australia (desert). It is on ABC Rural News and may be a help to you. Trials reveal potential for garlic-growing in Northern Territory Posted 7 Oct 2016 MAP: Alice Springs 0870 A trial exploring the capabilities of seven garlic varieties in the red centre is showing some early positive results. Seven varieties of garlic are being trialled at the Northern Territory's Arid Zone Research Institute (AZRI), alongside the standard industry garlic variety, Glen Large. The Alice Springs environment will demonstrate how varieties that have never been grown commercially in the Northern Territory respond to extreme cold and extreme heat. Central Australian Horticulture Development Project manager and researcher Stuart Smith said despite challenges such as poor water quality, the results so far had been positive. "We're hoping, because we're just south of the Tropic of Capricorn, we're just a bit a little subtropical, that we're in the right area," he said. "We've got the right heat profile, right day length and we're able to grow some good bulbs. "If it'll grow here, it'll grow anywhere. "Central Australia is a bit isolated from the rest of Australia so it doesn't have the pests and diseases of the other garlic-growing areas." Plan to get garlic onto market early in season Mr Smith believes there is a market opportunity for garlic that grows early in the traditional growing season. We thought we could get a few varieties to come early on the market, so we can get some good prices for them and replace the imported garlic," he said. The first successful harvested trial crop has reached a stage of maturity that would be ready for market. "It's got a code name called AF. We're getting some good-sized bulbs out of this," Mr Smith said. "I estimate we're getting 6-8 tonnes per hectare."

(ABC Rural: Katrina Beaven) Mr Smith said the early trial results were encouraging despite poor water quality and salty soils. "We have to keep watering them pretty constantly to keep moving the salt out of the root zone," he said. "The water we're using at AZRI is pretty low quality. "Most of the water other people are using in horticulture around the Central Australian region is a lot better quality than this." Mr Smith said the research results would also add value to what was being learned by a grower at Orange Creek Station, south of Alice Springs, who is conducting a commercial garlic trial this year.
