shrub or small tree in wet ground
I have a small brick built planter which measures 4 ft x 3 ft and the soil is made up of lots of manure which i dug into the soil this year . As a result the ground is very moisture retentive! I would like to grow a small tree of large shrub to be the middle feature which i will surround by planting bluebell bulbs. Has anyone got any advice on what would be best in this location.
