Three Timbers Installation Guide (Feel Free to Follow): California Gold Bougainvillea

Planting Guide:

• Location: Full sun (at least 6 hours of direct sunlight daily for optimal growth and blooming)
• Soil: Well-drained, sandy or loamy soil (slightly acidic to neutral soil preferred)
• Spacing: Space plants 3-4 feet apart to allow for optimal growth and air circulation
• Planting Depth: Plant at the same depth as the root ball, ensuring the top of the root ball is level with the surrounding soil surface
• Support: As a vining plant, California Gold Bougainvillea requires a trellis, fence, or other support to grow upward. It can also be trained into a bushy form.

Watering Guide:

Watering After Planting:

• Initial Watering: Water thoroughly immediately after planting to saturate the root ball and surrounding soil
• Frequency: Water every 2-3 days for the first 2-3 weeks to help establish the root system
• Watering Amount: Provide 1 inch of water per session to ensure deep watering around the roots

When is the Plant Established?

• Timeframe: California Gold Bougainvillea is considered established after 2-3 months when the roots have spread into the surrounding soil and the plant begins showing consistent new growth

Watering Once Established:

• Summer: Water every 7-10 days during the hotter months. If temperatures exceed 100°F, increase watering to every 5-7 days. Provide 1.5-2 inches of water per session.
• Winter: Water every 3-4 weeks during the cooler months, depending on rainfall. California Gold Bougainvillea is drought-tolerant once established but benefits from occasional deep watering during dry winter periods.

Drip Irrigation Setup:

• Placement of Emitters: Place the drip emitters 12-18 inches away from the base of the plant to ensure that water reaches the root zone and promotes deep root growth.
• Flow Rate: Use emitters with a flow rate of 1-2 gallons per hour for slow, deep watering. This ensures that water penetrates deeply into the soil and supports healthy root development.
• Number of Emitters: Place 1-2 emitters around the base of each plant to ensure even water distribution around the root zone. Adjust the number of emitters as the plant matures.
• Irrigation Zone: Set up a dedicated irrigation zone for drought-tolerant plants like Bougainvillea, allowing you to adjust the watering schedule based on their specific needs.
• Adjusting Frequency: In the summer, you may need to increase watering frequency to every 5-7 days to keep the plant hydrated. In winter, reduce watering to every 3-4 weeks, or adjust based on rainfall.

General Watering Tips:

• Soil Check: Check the soil moisture regularly. Water when the top 2-3 inches of soil feel dry to the touch.
• Avoid Overwatering: California Gold Bougainvillea is highly drought-tolerant once established. Overwatering can lead to root rot, so ensure the soil drains well and avoid standing water around the base.
• Mulch: Apply a thin layer of mulch around the base to help retain moisture, regulate soil temperature, and reduce weed growth. Avoid placing mulch directly against the plant’s stem to prevent rot.
