When Your Garden Gets Less Sun Than You Think
Many beds feel sunny at noon and still fall short of six hours. Trees leaf out in May. A new fence cuts the west side. A garage shades mornings. The Sun Hours desk only helps if the hours you enter match the real bed.
Why Counts Drift Down
- Deciduous trees: bare branches in March look open. By June the same spot is part shade.
- Neighbor structures: sheds, two-story walls, and privacy fences block low morning or evening sun.
- Season: winter sun is weak and low. A bed that works for fall greens may starve summer tomatoes.
- Cloud belts and tall crops: corn or sunflowers cast shade on beds beside them.
NC State Extension and similar beginner guides stress watching the site through the day and season, not only at lunchtime.
Fix the Plan, Not Only the Soil
- Re-measure after leaf-out. Update the bed hours on Sun Hours.
- Move fruiting crops to the brightest bed. Put lettuce and spinach in the dimmer one.
- Raise containers onto a sunny driveway or deck for the season.
- Prune only when it is safe, allowed, and will actually open a useful sun window.
What to Grow When You Are Stuck
If you cannot get past three to five hours, lean on vegetables that grow in part shade. Skip forcing tomatoes into a three-hour courtyard. Weak growth there is usually light, not a missing fertilizer blend.
Measure with how to measure garden sun hours, then shop seed that matches the bed you have.
