Best Begonias for Sun and How to Fertilize for Maximum Blooms

No Begonia Loves Full Sun, But These Tolerate It Best

Wax begonias (especially the 'Wings' hybrids) handle more sun than other types. Bronze-leaved varieties also show better sun tolerance than green-leaved ones.

Fertilizer for Blooms, Not Just Leaves

• Choose: High-phosphorus fertilizer (middle number highest), e.g., 5-10-5 or 10-20-10.
• Avoid: High-nitrogen formulas (like 20-10-10)—they produce lush foliage at the expense of flowers.
• Apply: Time-release at planting + liquid bloom booster every 2–3 weeks, or follow label for granular.

Quick Tips

• Water at soil level to prevent leaf spotting.
• Deadhead spent flowers to encourage more buds.
• In Zone 8b, provide afternoon shade for best performance.
