Count direct sunlight on the place where the pot will sit. A bright room or a sunlit wall is not the same as hours of direct sun on the leaves, and seasons change the pattern.
Under two hours: choose foliage for low light
Edible harvests may be limited in a very shaded spot. Try attractive foliage plants suited to your climate, or a small test pot of mint or leafy greens in the brightest position. Mint spreads readily, so keep it in its own container. If little direct sun reaches the balcony, set expectations around leaf growth rather than abundant fruit.
About two to four hours: experiment with greens and herbs
Leaf lettuce, spinach, and some Asian greens are worth trying in a cooler, brighter area. Chives and parsley can also be options depending on season and variety. Watch for stretching, slow growth, or a plant leaning toward a light source; those signs may mean it needs a brighter position.
About four to six hours: a flexible middle ground
Many herbs and leafy crops can do well here, especially with morning sun. Choose compact varieties and use the plant label to check local timing. A balcony that receives late, reflected afternoon heat can behave differently from one with gentle morning light.
Six to eight hours: try warm-season crops
Tomatoes, peppers, eggplant, and squash generally need more direct sun than leafy greens. University of Maryland Extension recommends around 6–8 hours for warm-season crops and 3–5 hours for cool-season crops in containers. Look for dwarf or bush varieties and match planting dates to your local growing season.
These ranges are a starting point, not a universal guarantee. Climate, cultivar, heat, reflected light, and container size all affect results.
Make your first trial easy to learn from
- Pick one plant you enjoy eating or caring for.
- Write down the sun hours and location.
- Use a pot with drainage and the recommended mature size.
- Check moisture and growth regularly, then adjust placement.
