What is full sun?
Full sun means at least 6 hours of direct, unobstructed sunlight per day. Most vegetables, many herbs, and the majority of fruiting plants require full sun to produce well.
Full sun is the gold standard for productive food gardens. Most warm-season vegetables — tomatoes, peppers, squash, corn, cucumbers, melons — need 8 or more hours of direct sun to develop properly and produce heavy yields. Even many cool-season crops like spinach and lettuce that tolerate shade will produce more and stay compact longer in full sun when temperatures allow. When selecting a site for a vegetable garden, full sun is almost always the first requirement to check. South-facing and west-facing aspects tend to offer the most reliable full-sun exposure in the Northern Hemisphere. Reflected heat from walls and fences can create beneficial microclimates in cooler zones.

Tips for full sun gardening in Zone 12
- 1
Track sun patterns across the day before selecting a planting site — a spot that looks sunny in the morning may be shaded by afternoon.
- 2
In hot climates (Zone 8+), afternoon shade for 1–2 hours can protect cool-season crops from heat stress without disqualifying the spot as full sun.
- 3
Reflective mulches (silver or white) can increase effective light for crops in borderline-full-sun spots.
- 4
Prune overhanging trees and tall shrubs to improve sun access as the season progresses.
- 5
Plant root crops (taro, yuca, yams) as year-round staples
- 6
Grow spice crops: turmeric, ginger, lemongrass, allspice
