Alturas, Florida, has been hit hard with citrus greening. Trees in groves continue to be removed at an increasing rate. This photo, next to one of our groves, shows the devastating result of this disease. At least the risk of transmission of disease to our grove is reduced once this grove is taken out.
I recently heard from the Florida Department of Citrus that they like one of my citrus grove photos that appears on a site I did for the Indian River Citrus League. After a day or two of negotiating, we arrived at an agreement for the FDOC to license the image for their national and international marketing program! Keep on the lookout for it–it might appear in a grocery store near you!
This image was taken at sunrise on November 21, 2010, on the west shore of Lake Hancock in Highland City, Florida. We rented an elevation platform and just hoped we got great sunlight and clouds to go along with it. Sure enough, we did!

WORKING DRAFT VERSION
In the first post in this series last week, I reported on some of our management success in controlling dieback in Early Pride citrus. I took a look at the symptoms of the problem and examined the progress of the disease over the course of a year in a new block we planted. Although I didn’t go into detail last week, I made the point that most of the dieback we saw was due to some sort of physical trauma. This week, I’ll take a detailed close-up look at those symptoms, and illustrate how I came to the trauma conclusion. In my next report due later this week, I’ll go over the findings of the USDA regarding secondary pathogens, and the treatment programs we used to help contain the problem in our grove.
Today, I had a chance to drive around the citrus groves in this area with some visitors from California. We talked about alternative crops, marketing, and variety licensing among other things. During the visit, we happened upon a section of one of the groves showing what I would call classic, textbooks symptoms of greening. Seeing the differences in the patterns in these symptoms can be subtle, but once you get accustomed to the general look, you begin to recognize them more easily. Here are eight examples we saw today.
Citrus groves in Florida can often be overgrown with fields of wildflowers. This time of year, we till them into the earth for organic matter. Later, this same practice will help expose the soil which will help with freeze protection.
In April, 2014, I met Drew Dyess and a friend for a photo shoot in a citrus grove. Drew, who works for Plant Food Systems, wanted some good photographs to use in his work. This would be one of those rare opportunities where you can get great images of citrus people working in the grove. I met Drew and his friend after work one afternoon. His friend helped us out by serving as our lighting director, and Drew carried on about his work while we shot away. The results turned out great–be sure to check out the gallery below!

I have recently become more interested in olives and growing them in Florida. Olives might be perfect for replanting citrus areas where trees succumb to greening disease. As has been covered at several public presentations recently, olives have a lot going for them. It seems they once were thought of as a good plant for Florida, but somehow that was lost as citrus became more popular in the state around the turn of the century.
We recently planted our first ‘Early Pride’ trees in Polk County. Here are some of the various symptoms that appeared back in October 2013 on the trees soon after they were planted. We’re currently looking closer into the dieback issue to see if the various symptoms have similar or different causes.
