Planting ideas for Shallow soil/Concrete Underneath
I'm in a muddle!!
We have just put edging down one side of the garden, to then cover with shingle and have some pots on. However I would really like to plant a few plants in bedded into the gravel under the membrane.
The problem is, that where the fence is, there is about a foot of concrete coming from down the whole length of the fence and its really frustrating trying to get deep enough to plant anything.
Is there anything that has really shallow roots, that I can put down between the pots to break it up a bit, or am I wasting my time totally, and should just stick with the pots??
