Dahlias 2021

I've also a large border that is sloped, and has a large hawthorn tree near. I'm going to see whether I can grow dahlias in this. It does get sun most of the day during summer - maybe a touch of shade on the edges. So started planting out - unfortunately the end third of the bed is full of annual flowers. I will just leave them and I will change things around next year if this works. Ideally I would leave the tubers in here. The soil is lighter, it's very drained and is sheltered by the house, and then two walls. So doesn't get much wether like the rest of the garden.
