This does seem a bountiful year for acorns. My rear garden borders six other area's......four other gardens...an end to a cul-de-sac and finally a Scouts compound which has a large wooded area of oak trees.....these oak trees are very tall and have a huge spread of branches which stretch at least thirty feet plus into my garden....and are dropping acorns at approximately one every 10 seconds. We have raked up over the last three weeks..... two full to the brim garden wheelie bins....these bins weigh so much it is difficult to tip the bin and wheel it out to the kerb side.....so I just drag it. When indoors you can hear acorns bouncing off the greenhouse all the time.....and walking in that part of the garden can be quite dangerous.....they can be quite painful falling from quite an height on to your head. If scouts did bob-a-job still (shilling ago if I remember) they can come round and pick-em up themselves.
