AZ Plant Lady House Call: What’s Wrong With My Bougainvillea?
**Disclosure: This post contains an affiliate link of a product that I use in my garden and I recommend to those who are experiencing similar problems.
A week ago, I was called to see one of my regular clients to see how her landscape was progressing since she had installed a lot of new plants at the beginning of summer.
The majority of her plants looked great considering she had planted them at a particularly tough time of the year.
BUT, what caught my attention was her bougainvillea shrub.
The leaves were quite ragged and looked like something had been chewing them.
In addition, there were some small black droppings scattered among the leaves.
The diagnosis was relatively simple…
The culprit was bougainvillea looper caterpillars.
Now, you rarely ever see the caterpillar itself. It is rather small and looks like a yellow-green to brown colored inch-worm.
The signs are ragged leaves that appear to have been chewed along with the black droppings.
My bougainvillea growing in the back garden. I haven’t seen any signs of caterpillar damage yet.
If you see similar damage to your Bougainvillea, don’t panic. Most Bougainvillea can handle the damage from the chewed leaves.
However, if your Bougainvillea is young, or if the infestation is severe, you can help to get rid of the caterpillars by spraying your bougainvillea with a product containing BT (bacillus thuringiensis), which is an organic pesticide. I use Safer Brand 5163 Caterpillar Killer II Concentrate, 16 oz in my own garden.
In the case of my client’s bougainvillea, I told her that the damage was not severe enough to warrant any treatment.
Some of you may see similar damage to your yellow bells or orange jubilee shrubs, which I wrote about in a previous post, “Oh No, What’s Happened to My Shrubs”.
**In the future, I will be sharing some gardening problems or design challenges that I encounter during some of my consults and their solutions.
My hope is that they can help you in your own landscape 🙂
I hope you have a great weekend. We will be celebrating my 3-year old twin nephews birthday at our house tomorrow morning. I’ll may post a picture or two next week from the party.
My daughter, Rachele, is doing well after the first week of her combat training in Mississippi. But, she did share some funny stories that I will share with you next week too!
Can't wait for the pictures …. and the stories too!
I found one on mine!!! I saw little black dots too, I should have squished him but I moved him away. I'm still scared of squishing bugs…
Thank you for the article! I have this problem too and live in Tucson. You mentioned a product containing BT (bacillus thuringiensis), which is an organic pesticide – where can I find it? What's the product called?
You should be able to find it at your local nurseries or Amazon. Last time I checked, the big box stores didn't have it.
The product is called BT.
I hope this helps!
I have an atrium with an older magnificent bougainvillea that is having this problem. Ii will be very grateful if this product works.
