How to Grow and Care for Bougainvillea ‘Sundown Orange’

This plant is a great choice for new and experienced gardeners alike. Let’s walk through the steps to make it happy.

☀️ 1. Full Sun = Full Bloom

Bougainvilleas need at least 6 hours of direct sunlight per day. No compromises here.

More sun = more flowers. Less sun = more leaves and fewer blooms.

Find the sunniest spot in your garden or patio. That’s where ‘Sundown Orange’ belongs.

🌱 2. Soil Should Drain Quickly

Bougainvillea roots do not like to sit in wet soil. They need fast-draining soil to stay healthy.

• Use sandy, loamy soil in the ground.

• In containers, use a cactus or succulent mix with excellent drainage.

• Avoid clay or heavy, compacted soils.

If the water doesn’t drain, the roots can rot—and that’s one of the few things that can harm this tough plant.

💧 3. Water Sparingly

Bougainvillea thrives on dry conditions once it’s established.

Here’s a simple watering guide:

• After planting, water deeply to help roots settle.

• Once established, allow the soil to dry out between waterings.

• In pots, check that the top inch is dry before watering again.

Tip: Overwatering is the #1 reason bougainvillea doesn’t bloom. A little stress = more color.

🌸 4. Feed for Bracts, Not Just Leaves

To encourage those fiery blooms, feed with care.

• Use a low-nitrogen, high-phosphorus fertilizer (like 5-10-10).

• Apply every 4–6 weeks during the growing season.

• Avoid high-nitrogen lawn fertilizers—they'll give you green leaves but no blooms.

Want nonstop color? A little bloom-boosting plant food goes a long way.

✂️ 5. Prune for Shape and More Blooms

Pruning is essential to keep your bougainvillea looking its best—and to trigger more flowering.

• Trim long or unruly branches after bloom cycles.

• In early spring, give it a more serious shaping.

• Always remove any dead or weak growth.

Don’t be afraid to cut back. Bougainvillea loves a good pruning and will reward you with fresh growth and new color.

Growing in Containers

Bougainvillea ‘Sundown Orange’ is fantastic in large pots, especially in cooler climates or for patios and porches.

Container care tips:

• Choose a pot at least 18" wide with drainage holes.

• Use well-draining soil mix.

• Provide a trellis or let it spill naturally.

• Water deeply but let it dry out completely between waterings.

• Feed monthly with a bloom-boosting fertilizer.

Bonus: Containers let you move it indoors or protect it from frost in colder zones.

Cold Climate Care and Winter Tips

‘Sundown Orange’ is best in USDA Zones 9–11. It won’t survive a hard freeze outdoors—but don’t worry, you still have options.

If you live in a colder climate:

• Grow it in pots and bring indoors before frost.

• Mulch heavily around in-ground plants in fall.

• Use frost cloth to protect plants during cold snaps.

Even if frost damages the top, many plants bounce back from the roots when warmer weather returns.

Common Questions

Why is my plant not flowering?
Usually it’s getting too much water, not enough sun, or too much nitrogen. Adjust those three and you’ll likely see blooms.

Can I grow it indoors?
Not easily. Bougainvillea needs direct sun, warm temps, and airflow. If grown indoors, use a bright sunroom or greenhouse. Otherwise, it’s happiest outside.

Is it safe around pets or kids?
Bougainvillea has sharp thorns along its stems, so use caution around walkways, children, and pets. It's not highly toxic, but thorns can scratch and irritate.

How fast does it grow?
Very fast. Once it settles in, it can grow up to 20–30 feet or more, depending on support and climate. It will need guidance and pruning to manage.
