boggy shady claggy clay
My open woodland garden is in North Cornwall within reach of salt laden Atlantic air. We experience very high rainfall, gales but don't suffer from frost. The ground is heavy clay which holds surface water for long periods of time offering a challenging environment in which to garden.
2017 was a wipeout because of the extensively wet weather which meant that moving a wheelbarrow about has compacted what soil we had. I am wanting to grow a wildflower garden in this mainly shady or open shaded ground which is very damp for a lot of the year full of clay and occupied by alder, ash, oak and sweet chestnut trees.
The area is mainly flat and has a lot of groundwater in patches and extends to about 30 x 60 metres. There is very little growing in the ground because of the fairly dense shade afforded by so many broad leaved trees. I have read that spring is preferable to autumn for planting in such damp conditions.
I am hoping to attract birds, bees and insects and introduce colour to this patch of ground within 2-3 years. Am I being unrealistic? Any advice please as to what and when to plant that is likely to survive?
