Maybe a daft question. After moving to our new house I'm realising that the garden is much more shady than I had thought. Although the back of the house faces south, the garden is shaded by the house at the bottom of the garden and is completely in shade by 5.00 now. So my question is, can I get an idea of how much higher the sun will be in the summer and therefore how much sun the garden will get then, so I can plan my planting, seating etc.
