We have planted 26 of them so far! The entire area is going to be underplanted with plants the bees will love. Hopefully next year we can encourage a Bee Keeper to leave a hive or two in the orchard area.
The world shortage of bees, and particularly for us in the U.K., is a growing concern. Universities over the U.k. are at present trying to find out exactly why there is such a worrying decline. This year we have not seen one Honey Bee! The Bumble Bees, although in plenty in our garden, are suffering from an internal mite. We have found many dead Bumbles. But other causes for the Honey Bee are now under scrutiny. e.g., modern farming methods.
