Oh, bougainvilleas; just when I thought I’d written all I co
uld write about you, this happens. All in all, it’s been a very mild winter here in Tucson but we did have 1 evening in mid to late December when the temps dropped to 29 degrees. Brrrrr – the bougies weren’t very happy about that. I want to show you what light freeze damage looks like on bougainvilleas and tell you what my plan of action is.I worked at a wonderful nursery in Berkeley many moons ago. One January a very atypical 4-5 night consecutive freeze hit the Bay Area. My client who lives on the coast just south of San Francisco had an iced-over bird bath! The bougainvilleas in the Oakland and Berkeley Hills totally froze to the ground. Some started sprouting back up in mid-spring but many bit the dust.
Light Freeze Damage on Bougainvilleas
What am I planning on doing about it you ask? Absolutely nothing right now except for sweeping up the fallen leaves and flower bracts. At the end of February/beginning of March, I’ll see low the temps are dropping and decide whether to prune then or wait. I don’t want to force out a lot of new growth by pruning and have the bougainvilleas get hit even harder because their outer protection has all been cut away.
The flowers have dried on this branch & a couple of the leave
This bougainvillea is right around the corner from me. The outer & upper branches have been hit on this 1 too.
Here’s another of my bougainvilleas. The leaves are always a paler green on this 1 but the markings are due to the freeze.
That’s new growth swelling from the nodes. Old leaves will all fall off & that fresh new growth will appear as the days get longer & the weather warms.
If your bougainvillea has been hit by a freeze (light or hard) in early winter, resist the temptation to have at it with your Felcos at this time. A light freeze will just superficially effect the plant so wait until the evening temps are consistently warmer. With a hard freeze you may have to wait even longer to see if any new growth is appearing. And, no fertilizing your bougie at this point thinking you’re going to pamper it.
Don’t worry if the leaves on your bougainvillea are turning yellow and dropping off at this time of year. Here’s the scoop: Bougainvillea is native to coastal tropical areas. One of the causes is the cooler winter temperatures. In some climate zones it’s semi-deciduous and the leaves partially or totally fall off.
Have you ever experienced freeze damage on your bougainvillea?
Be sure to check back in late winter/early spring because I’ll be doing a post and video showing you how I prune my Bougainvillea Barbara Karst after this light freeze. For now she’s just going to have to wait!
