Why Certain Herbs Need Full Sun
You’ve probably noticed that herbs grown in bright sunlight tend to look fuller and smell stronger. That’s not just coincidence—it’s science.
Sunlight Drives Flavor and Aroma
When herbs receive 6–8 hours of direct sunlight, they increase their production of essential oils. These oils are what give rosemary its sharp scent, lavender its sweetness, thyme its earthiness, and oregano its heat. The more sun they receive, the more intense these oils become.
In other words:
- More sun = more flavor
- More sun = stronger aroma
- More sun = healthier plants
Sunlight Strengthens Growth
Herbs need full sun for strong photosynthesis. When they receive enough light, they:
- Grow thicker stems
- Produce more leaves
- Resist disease
- Stay compact instead of growing leggy
- Develop vibrant, healthy colors
Without enough light, you’ll often see:
- Thin, floppy stems
- Pale or yellowing leaves
- Weak aroma
- Slow or stunted growth
How Much Sun Is “Full Sun”?
For most herbs that need full sun, aim for:
- 6–8 hours or more of direct sunlight daily
- East-facing or south-facing areas for strong morning and midday sunlight
- Avoiding shade from fences, trees, or buildings
