Thank you for this very informative video.It's important for us regular home growers to SEE what diseases actually look like ,so that we don't confuse bad watering or care for a disease.
Thanks for this Dan. As I live in New Zealand the HLB stuff hasn't been relevant to my situation. However a lot of this probably is. I'm now going to do further research on Cachexia and Citrus Leaf Tatter as they may be the answer to some issues I've been having with some of my trees. All the best to you and yours for the holidays.
I’m having trouble identifying the disease on my orange tree, it’s 13 years old and this odd growth started three years ago, can’t seem to find any information online. Do you know of any resources to identify the issue?
Have you contacted University of California ANR? I gave a link to them in the video description: You can find University of California ANR farm advisers and specialists who can help with citrus disease questions via the link below: ucanr.edu/About/Locations
I suspect something wrong with my citrus tree. Contacting someone who knows anything about citrus is surprisingly difficult here in California. So instead of destroying my tree, I will let it keep growing. Luckily the neighbors tree has been infected with what appears to be the same thing. Maybe now that there are 2 trees infected, I will be able to get some help diagnosing the issue.
I'm not sure if you saw these videos, but I gave resources here where you should be able to reach someone who can help: www.fruitmentor.com/citrus-disease-california Here Dr. Ashraf El-Kereamy even asked me to give out his email address so that he could help people: www.fruitmentor.com/citrus-tree-care-fertilizing-citrus-trees I hope that you can get to the bottom of your problem.
We have a lot of imported plants here in FL and a rather large Asian population in our particular area -- I'll be keeping a look out for any of these symptoms and let you know if we see any signs
Thank you! It is unfortunate that huanglongbing is already widespread there. I hope that my channel helps prevent things from getting worse for citrus in Florida.
Dan have you ever had issues with cicada larvae causing problems with citrus? I graft my own (in containers) and have had some 'mystery' trees that never really grew well despite grafts taking. The signs are low vigour and lack of proper flushing. Last month I discarded a tree that had dropped its leaves last year and, on unpotting it I discovered three big fat cicada larvae sucking on the roots. More recently on some small tress that were also not doing well (but which are hard to replace) I've seen empty cicada 'shells' on the trunks and emergence tunnels in the potting media. I get that it's unlikely that they're a disease vector but they've cost me a few trees and have set some other young potted trees back several years. I guess this is where I say I don't use sprays on my citrus and in fact gravitated towards citrus *because* they generally do well without sprays. Thanks for any input you may have. Edit: I should mention that, while I've seen cicada oviposition sites on prunus and many other trees I've never noticed them on the citrus. However you can be sure I'll be looking a lot more closely in future - and keeping those other trees well away from my citrus.
I have seen some sort of larvae in the bottom of potted citrus plants. I am not sure what they were. It did not seem like they were causing problems, though. I think my biggest problem in growing potted citrus has been too much moisture at the bottom of the pot. I have mostly planted them in the ground, but I am experimenting with a bunch of potted plants right now.
I have a small lemon tree (1 meter tall, very young) that got infested with some local plague. Some leaves started greening and growth is slow, which I suspect is some sort of fungus that's stunting development. Are these diseases curable or do I have to try again, planting a new tree?
If it is indeed a fungal disease, you may be able to treat it with a fungicide. But if it is a graft transmissible disease like the ones in this video, the best bet is to replace the tree.
Bro pls share what to do outside America we are in India ..pls help how to choose disease free Scion.....and pls suggest ways to stop above mentioned disease it's preventive pesticides and fungicides...
I did a series of interview videos that includes many tips for avoiding disease: th-cam.com/video/d4JwPijoAIg/w-d-xo.html The videos on Citrus Pests and Citrus Propagation and Disease should be especially helpful. I do not know of a program like CCPP in India. If you discover one, please let me know.
Unfortunately a lot of these diseases are near Tallahassee Florida. It’s so sad, but they’ve noticed difference in citrus under Live Oak trees. They’re not sure if it’s the oil from live Oak tree or The over head shade it gives to the citrus.
It is so sad. My grandmother had a house in Florida and that is where my love for citrus started. I remember climbing her orange tree and eating the fruit right off of the tree when I was very young. We are in a dark period now, but eventually the research will pay off and it will be easier to grow citrus again in Florida and other places affected by HLB.
My lime was perfect until last harvest. It’s producing limes that are dry and yellow inside. The fruit on the tree seems normal until you open it. I don’t know what could be wrong. We’ve had 5 years of biannual harvests from this tree. The leaves are normal. This is absolutely confusing
I heard from someone that when citrus tree has some branches have bigger leaves than others branches we need to take it off, he called cancer , is this is real disease ?and i need to take that branch off??
I wonder if they meant citrus canker which I show at the 6:09 point in this video. It is a very nasty disease and my understanding is that trees with canker are normally removed.
I always wondered if anybody tried to eat the fruit from a tree having HLB if it would make them sick. Obviously, the fruit would be undesirable. But, is it dangerous to eat it?
It just tastes bad. It is not dangerous to eat. The bacteria that causes HLB does not do well outside of citrus trees and Asian citrus psyllids. Scientists have had great difficulties culturing the bacteria in the lab and that has slowed down the research seeking a cure.
Dan you have by far the best channel I have found in regards to grafting and explaining the spreading of fruit tree diseases. Please do keep up the work. Greetings from Greece!

Thanks for the feedback, Shaun. I am glad that you have found it helpful. I would not be surprised if some of those diseases were in New Zealand.

Can you kindly state the solution of stem rot in citrus?
Trees in south texas started dying late march. There was a chemical fog for a couple of mornings before plants and trees started wilting and dying.

Should I discard my Meyer's lemon plant since its got alternaria fruit rot and the buds are turning black and falling
Very informative video for citrus growers. Thank you so much
Glad it was helpful!

How to treat Citrus greening disease

Dan, you are direct and your presentation is precise and elegant. Thank you for this service.
Thank you!
Ikr he is not like other youtubers who give a long ass introduction
I live in India. Very nice to see your video. I could not understand the language myself. But I also cultivate site juice in India.
My lime was perfect until last harvest. It’s producing limes that are dry and yellow inside. The fruit on the tree seems normal until you open it. I don’t know what could be wrong. We’ve had 5 years of biannual harvests from this tree. The leaves are normal. This is absolutely confusing

Thank you!
Thank you for very importent items.
You're welcome!
Thanks for your informative video...👌👌
Thank you!
Looks like a lost cause
Not a lost cause, but the diseases certainly make it harder to grow citrus in the areas that have them.
