If you have a sprouted white onion and were to want to divide it after it sprouted: Remove the outer scales (layers) of the onion that will not completely encircle one of your divisions. Then cut the basal plate in sections to separate your desired transplants. Next, plant in prepared soil 1 foot apart in rows 2 to 3 feet apart. For your effort you will have multiplied your original onion that would have happily gone to seed with several clones that will go to seed, and if they survive, the seed yield and quality will be less than that of the original. But why stop there! If you were so taken by this onion and wanted to briefly share with the world. Scaling or chipping the bulb would have been an option. Sadly, preparations would have had to had been made months ago... I looked at your posts made this week (It has been a banner first week) ... YOU have wasted my time and that of others who wish to help a fellow gardeners. If that is what you have wanted 'TrollKingster' or whoever, be happy! take it and go away. It would be interesting if someone who could check the IP addresses could check those supposed forum "conversations" out... With that moniker, supposed clulessness about simple matters about concern over replacing your soil after using fertilizer and buying soil when it is everywhere, you asked these questions while somehow being aware of fairly specific differences in the growth habits of alliums? - ya, right! I have noticed over time there have become fewer that can answer a question on this site- trying to help at some point must just not be worth it. Best wishes.

Socalgirl, While I don't know a thing about onions my best advice to you about the garlic is to Google "how to grow garlic" you will find umpteen different sites telling you what you need to know about when and how to plant them. Seed bulbs are just like the bulbs you eat...the only difference really is the size of it. People grow big garlic bulbs just to sell to others like yourself. There are many different outlets for planting stock out there and is easy to buy online. Ebay is a good source for garlic bulbs in September. A local farmers market is another. I would not go to the big seed retailers your first year growing though..they're pretty expensive. You can go to your local grocery store and buy some bulbs in October-November and plant those is you want to play with the idea of growing garlic without a big outlay of cash. Hope this helps

Here that would be the 1st of September and transplants set out Nov 15, just before the rains start. Harvest around the 15th of June. Temps are usually 2.2C to 43.3C. If you are not in this range, adjust accordingly. Absolutely the best would be to ask some one who grows onions in your area. Perhaps call one of the Israeli research stations listed in the link. Here is a link that might be useful: research stations and other regarding onions

Dixondale Farms has the best onion growing advice on the net as far as I am concerned. Be sure to click on their FAQs and Guides section at the top. They will set you straight in no time.
