Why That "Sunny" Spot Isn't as Sunny as You Think

Stand in your yard at noon on a clear June day and everything looks sunny. So you plant tomatoes by the fence, and by August they're leggy and barely fruiting. What happened? The spot was never getting the hours you thought — you just happened to look at the one moment it was lit.

Shadows move all day

The sun crosses the sky from east to west, so shadows swing across your yard hour by hour. A bed that's golden at 9 a.m. can be in deep shade behind the garage by 3 p.m. The total that matters isn't whether a spot is sunny right now — it's how many hours of direct sun it collects from sunrise to sunset. Two beds a few feet apart can differ by three hours.

And they move all season

It gets trickier: the sun rides higher in summer and lower in spring and fall, so shadows are shorter in June and longer in April and September. A bed that bakes in midsummer can be shaded out by that same fence in October. And a tree that's bare and lets light through in April becomes a solid shade umbrella once it leafs out in May.

How to actually measure your sun

The classic method: pick a clear day, walk out every hour from dawn to dusk, and mark on a sketch which beds are lit and which are shaded. Then do it again a few weeks later, because the sun has moved. It works — most people just never finish it.

The faster way is to let the math do it. Bee Come Native takes your address, your property outline, and the real height of your house and trees, and calculates the direct sun hours on every square foot of your yard — hour by hour, and season by season. The hot corners show up red, the shady beds blue, and you plant each thing where it'll actually thrive.
