It always pays to do research before you do anything in the garden. This morning I went to do some weeding and saw that the Elephant Garlic that we planted in February was flowering I in my noviceness thought that it was ready to harvest. So I carefully lifted it out and rinsed the soil off, only to find three very small bulbs, so I again carefully put it back and covered the roots with soil again. Then I went back inside and looked up Elephant Garlic on the internet and found that it takes two years to harvest, and when it flowers you are to cut off or bend the flower over to encourage bulb growth. Are there any other things I need to know about the onion, garlic, or leek families when they are ready to harvest?
