Espalier and fan for shorter wall
We are in the North East and have quite a long stretch (~15-20m) of dry stone wall. It's West facing, gets quite a bit of sun and is fairly sheltered. We were thinking about growing an espalier pear and maybe 3 fan plums, but the wall is only about 1.2m tall. I know you can get stepovers, so assume you can grow shorter but I wanted to ask if it would be likely to work and if there are any particular problems we might encounter trying to grow trees like that.
