I was going to say the same - is the area well drained?
The red shoots are simply new shoots, so it sounds as though yours isn't producing many.
My first thought would be to try feeding it?
Fascinating - I look forward to hearing whether it works!
Just had a hail shower but the sun is now out.
Very chilly, though.
You can buy one based on chicken manure which is very good.
The sonic scarer won't affect any other garden if there is a barrier in the way such as a hedge. The sound only carries a finite distance, too.
Sounds like a good thing to do, Wintersong
Nice to "meet" you
Hello again, Greeneddy!
Are you sure that it was 15"? I think that 8-10" is around about the maximum.
Topsoil can never be too deep, no. More of an issue is what's underneath it - you could have a pan of compacted rubble which would prevent drainage.
