How do I use horticultural spray oil on trees?
I live in San Diego and have 45 year old naval orange tree that gave me an enormous crop last spring. Now, and for some months, my tree is in bad shape – with twisty curly leaves, brown leaves that look like they have scale on them and generally in very bad shape. Your product seems to say to use this on the tree in a dormant stage. Well, orange trees are always green in California and so there is hardly a dormant stage.
Some oranges have developed, but drop off when they are green.
Can I safely use this spray on my tree NOW? It is in VERY bad shape and has never been sick like this before.
