As I walk my Golden Retriever through my neighborhood here in Sun Valley, I’ve noticed a rash of mold and mildew on citrus.
Here’s the deal.
With the sudden heat and the colder nights and mornings, mildew spots are appearing on your citrus. How do you solve the problem? First, do not water the foliage in the evenings and also use an organic spray to get to those aphids — ants will literally farm the aphids to make that “poop” that the ants love and promotes that white and black sooty mildew.
Another problem with citrus is leaf miner, which occurs with the new growth. Not to be gross, but it looks like a swirly trail on the leaves and someone spit on them! When I’m walking my Danica I have encountered many people having that problem on their citrus trees. They talk to me ’cause I have my Armstrong shirt on!
Also, there’s a product named Spinosad that is awesome working on those citrus leaf miners and in the past few years, the problem has been declining.
