Hi Greg, dont worry about the russian garlic, it will shoot up. Some take a little longer, some come up straight away. Youll find that they really like full sun - if they have shade during the day they will take a little longer to come up. If you have planted the bulbins (little nut like seed) they will probably not show until early spring, cheers

If you want to grow imported garlic purchased from a super market pick out a nice bulb feel around the cloves near the to top, if there is a slight swelling thats the one you want to buy.Get a small con.that will hold water 5mil deep quarter teaspoon thrive or seasol.leave for about three days.plant out 50mil deep.after 2 weeks my plants are now 80 ml high.

One other company for great Garlic is garlicworld.com. They are based in Port Campbell in Victoria, Simon and his wife.I got some lovely Californis purple from them. Not sure if they'd have any left now. A couple of years ago, I got some Purple garlic which came from Chile. I really don't like to buy out of area stuff, but I figured it would be a one off, and haven't bought much since, except for the garlicworld stuff. Melanie, the garlic is ready when the top wilts and leans over, as Jen has said. Sometimes, the plant goes into flowering mode, but usually not, usually it just falls over. The stem that falls is the bit you use to tie it up with, so if you let it die too much, you won't get the protective outer skin, or something to plait it with. I tend to wait until it looks a bit ratty, but hasn't died completely, about a week or so after it keels over. Then I dig it up, don't pull it from the stem, I learned that lesson the first year.!! Hope this helps.

Hi melanie, Garlic is usally ready to harvest when the stalks brown off and lean over. If you are desperate for some fresh garlic you can harvest a bulb earlier but must put up with the bulb being smaler.... good luck ..it gets easier with every year

Another source of organic garlic is Kookaburra Organics(google the name). They are based on the Sunshine Coast (Maleny/Conondale) in Queensland. We've just bought some from them for planting for the first time. They seemed very knowledgeable and definately very helpful.

I've seen varying information on when to harvest garlic - some say let it flower, other advice says not to let it flower. Does anyone know which is correct?

i have heard that is best to harvest after the flowering when the stem dries up, similar to onions.

We use Sam's Club garlic because it is cheap and quickly available.... ours were huge by May after we planted in October. We dug a deep rectangular in ground spot about a foot deep and filled the lower half with horse manure bedding and put blended sandy compost on top of the horse bedding manure (we actually planned on making a "hot bed"/cold frame there but termites usually destroy wood structures here at ground level) and our garlic were big as tennis balls! We recently tried planting in a bed that we didn't put a lot of fertilizer first and got VERY depressing results so I say go big or go home on nutrients in the bed first or you may be disappointed. I really do not think the type as much as the preparation of the bed is what gives the best results. We just wanted a lot of food for the least investment... you may have other goals. Either way... doesn't hurt to fluff up most anyplace with fresh soil/nutrients first.
