BOUGAINVILLEA is #10 – in our TOP 10 Heat Resistant Plants

Bougainvillea are tropical plants that thrive in outdoor areas with low rainfall and intense heat.  The 100 degree temperatures do not faze our Bougainvillea.  This flowering jewel is number 10 on our list of the BEST heat-resistant plants in Arizona.

Bougainvilleas are native to South America; therefore, it is drought resistant (instead of “drought tolerant”) because it is not a desert native plant.  Caring for and growing a Bougainvillea takes more effort but it is worth it!

Bougainvilleas flourish in pots and containers.  To grow this striking ornamental vine choose a very sunny place. Be sure your pots have holes in the bottom; adequate drainage is a must! Bougainvillea growing tip: Fertilize with Hibiscus Food.  Hibiscus food has more potash than many other fertilizers. Be sure to measure exactly the amount of food according to the size of your pot.

The amount of watering for your Bougainvillea is directly related to your area and the local weather. There are some basics —- Bougainvillea is a drought resistant plant, and requires very little water once established.  Be sure to let the soil dry between waterings; if your Bougainvillea’s roots stay continuously wet it will promote a weak and shallow root system. Wilting is the best indicator that watering is needed.  Don’t let it dry out completely as this will cause bracts and foliage to drop.

When choosing an area to plant your bougainvillea, remember that higher ground is best – as this makes water drain AWAY from the roots. Avoid overwatering.

In Florida, landscape professionals commonly perform a hard cut at the first sign of summer, and keep on a regular trimming schedule all summer long to maintain size of the Bougainvillea.  Pinching is the method of removing the soft tips of young plant stems to encourage fuller growth.  Bougainvilleas will send out several new stems just below the pinched tip.

The more regularly you pinch, the more your bougainvillea will branch and bloom.  The best time to prune or pinch is after the flush of color or flowering cycle is completed.  Flowering cycles are typically four to six weeks. Lets get pinching!

Stay tuned as the count down for the best heat survivors continues…
