Bougainvillea can take the Arizona heat!

Bougainvilleas are tropical plants that thrive in outdoor areas with low rainfall and intense heat, someone say desert!  They need lots of sun and are happy with Arizona temperatures reaching over 100 degrees. They have thin roots that are somewhat delicate and we find our Bougainvilleas take more of our attention in the garden.

My conclusion and my gardening experience with Bougainvilleas is that they are happier growing in large pots with good drainage.

The amount of watering needed 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 and mature.  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.

For Bougainvilleas planted in the ground:  At the time of watering, do it thoroughly – making sure that every inch of root gets watered!  I use long bamboo garden stakes to measure how far down the watering has reached and I soak until it reaches 8 inches.  This will create a stronger root system for your bougainvillea.  Deep watering is the key!

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.  Pinching is the method of removing the soft tips of young plant stems to encourage fuller growth.  This hardy plant will send out several new stems just below the pinched tip. I am going to prune/pinch all 6 of our Bougainvilleas this week. My Arizona Garden keeps me busy, and I love it!

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!

Grow your Bougainvillea Plant in containers and pots. They LOVE IT !!

Will my Bougainvillea plant grow in a container?  Yes and it will be a very happy plant.  Bougainvilleas do great in most types of pots and containers.  These plants are not easy to transplant so make sure the pot you choose is big enough to last the Bougainvillea for years to come.

Although they like their roots crowded in a container, Bougainvilleas do not like standing water.  Make sure your pot has good drainage so the Bougainvillea does not get root rot.

Fill your container with potting soil and place the bougainvillea plant inside.  Find a sunny location and it will be easy to keep your Bougainvillea happy and healthy.

Bougainvilleas have beautiful red, pink and purple colored bracts, which are specialized leaves that contain the plant’s white slender flowers.

Bougainvillea plants can grow rather large so they must be kept pruned in pots and containers.  You can train your Bougainvillea to grow up a trellis or in the shape of a tree.

During the winter, Bougainvillea plants can be most striking and provide gardens with abundant color.  Winter is when Bougainvillea Vines and Plants reach their peak color.

The small heart shaped bracts of the Bougainvillea are quite delicate to the touch, and are crinkly in appearance.

How long will a Bougainvillea plant display their color?  The length of time depends on how much sun and heat it receives and how healthy the Bougainvillea plant is.

Typically, a healthy Bougainvillea will bloom for about 3 weeks.

Bougainvilleas love sun and more sun.  They are heat tolerant and the hotter the better.  At the very minimum Bougainvilleas need at least 5 hours of direct sunlight.

Supply your Bougainvillea with regular monthly fertilization.  Nitrogen and phosphates are critical to flowering.  One of the best Bougainvillea fertilizers I’ve come across so far is BOUGAIN.

You can prune your Bougainvillea any time during the year because it does not affect bloom initiation.  If you want the Bougainvillea to grow up, then prune the outer branches.  If you want your Bougainvillea to grow out, then prune the new growth.  Trim your Bougainvillea drastically before bringing it inside for winter.

Bougainvillea plants and vines have a BLOOM CYCLE followed by a rest cycle whether you trim them or not.

I recommend a little trim or pinching at the end of each Bougainvillea bloom cycle as it promotes more budding for the next one.  Our plants just ended a bloom cycle so I will be trimming Bougainvilleas this week.

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.

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.
