He is the love of my collection and the bane of my life. He has had whiteflies all summer. I’ve been managing them, but in the last two days he’s had a ton of leaves turn suddenly yellow (see pic) and developed this brown pattern on others (first pic). Does it look like whitefly damage? Some context. For whiteflies, I’ve: -treated with neem oil -grown marigolds -washed him frequently Nothing has eradicated them, but I’ve managed the numbers. Weeks when I can’t mitigate he’s gotten a few yellow leaves but leaves stop turning yellow when I’ve gotten their numbers down. Other problems he has had: -out growing his pot. I repotted him twice this year because he’s had two fits of bad health and I suspected root rot. Both times they were super healthy but he was root bound badly. He’s taken off after I’ve repotted him both times -being nutrient deficient. The nursery recommend 6-12-6 fertilizer last time he had a bad spell, but I was repotting him anyway, so I just chose really good soil -being too dry (he needs water twice a day during Texas summers) -being too wet. Jury is out on this one but with our 50-90 degree weather he’s been staying wetter and seemed over watered at the pre-set once a day timing. He could now be too dry again though the soil seems fine. Bonus question: both the latest white fly treatment (pryerthin) and the 6-12-6 fertilizer is 1 diluted gallon to 1,000 acres. How am I supposed to scale that to a single bonsai? I can’t seem to find more reasonably measured products. If he wasn’t so sentimental, I wouldn’t be so desperate, but he is and the nursery sold off the mother plant (he is my second attempt) he is from so any help is greatly appreciated. The purple pot is when I got him last October and the second one is him a few weeks ago. ![Pièce jointe 1 sur 4](https://images.getplanta.com/v1/resize/Ih3oYQEcbg_XjI-FBIqPQ-xmFaRAp9hazpxtjR1O07w/XtF77SXWQMqHUN3eWdUMJg.webp?size=large) ![Pièce jointe 2 sur 4](https://images.getplanta.com/v1/resize/Ih3oYQEcbg_XjI-FBIqPQ-xmFaRAp9hazpxtjR1O07w/2mBESWvDQ4uQJkIkKifXPg.webp?size=large) ![Pièce jointe 3 sur 4](https://images.getplanta.com/v1/resize/Ih3oYQEcbg_XjI-FBIqPQ-xmFaRAp9hazpxtjR1O07w/97qZqRioTomlbwBbOk4cJg.webp?size=large) ![Pièce jointe 4 sur 4](https://images.getplanta.com/v1/resize/Ih3oYQEcbg_XjI-FBIqPQ-xmFaRAp9hazpxtjR1O07w/iq5Dg6l6S9GVQzV8clI2_A.webp?size=large) ## 2 commentaires ### Sunny a commenté le 2024-11-14 I feel your pain. I had three lovely gardenias that white flies loved more than me. The plants looked snow covered. We dug up and tearfully trashed the plants. I knew nothing about Neem oil pyrethrum back then. These are the common treatment methods that you’ve tried. You’ve also taken care of the soil. Were there pests in the soil like larvae? I would recommend watering with a tea of mosquito dunks soaked in the water if there are larvae in the soil. I’m not helping you much, I know. It’s all I can think of that’s not already on the internet #### Darcy ha respondido el 2024-11-14 I’m sorry about your plants! I honestly gave up on eradication so long ago that while I know I need to do something about the soil I haven’t had the heart to research it so I really appreciate your suggestion! --- _La communauté Planta (https://getplanta.com).
