I was looking at a patch of Sedum (not sure which, but not acre) and counted 30 bees of different sorts on it. Not yet got as many as we used to get in our previous place, but slowly building up the numbers. No spraying for a very long time before we came has helped.
We're getting quite a few Bumble bees and some of our neighbours Honey Bees. It's good to see them in the garden. I'm so glad we're completely organic - we just let nature do it's thing..
