Greasy spot has flared up in a few locations on cultivars like Valencia, and …

University of Florida Institute of Food and Agricultural Sciences researcher Xavier Martini recommends planting windbreaks on two or more sides of citrus groves.

At Citrus Expo, University of Florida soil scientist Kelly Morgan said nutrient uptake by HLB-infected trees can be improved by applying the proper amount of nutrition and managing pH. “Those two things go hand-in-hand,” he said. “As you reduce soil pH below 7, you increase the uptake of most nutrients. So we need to reduce our pH. Our pH has …
