When to harvest onions?
I'm fairly new to gardening and this is the first year I've actually had onions make it. I planted sets this year (a little late, not till the end of April).
I keep reading that they are ready to harvest when "the tops fall over". Do they fall over at ground level? Mine were about 18" high, but then the top 6" drooped over. Everything is still quite green, no yellowing, but technically the tops have fallen over. I don't see any signs of onions mounding up or anything, just lots of green foliage.
Any ideas here?
