Tomatoes want sun most of the day; ferns do not. A sun-hours map of your garden or courtyard shows which bed gets what, for any day of the growing season.
On a balcony, one point report tells you how many hours of direct sun the plants will get in April and in July.
What to check
- Hours of direct sun across the garden on a spring day and a summer day
- Beds that get under one hour
- How a neighbouring wall or building moves the shade through the day
- Sun on the balcony at the time you would sit there
How to do it
- Open your address and zoom in until the garden fills the view.
- Pick a date in the growing season.
- In Analysis, compute a 200 metre sun-hours map and read the colours.
- Tap a bed or the balcony for the exact hours.
