  • How do I use horticultural spray oil on trees?

    Created by Beda Johnson on

    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.

    Hi Beda –

    Our ALL SEASONS® HORTICULTURAL AND DORMANT SPRAY OIL is a self-emulsifying spray, composed of paraffinic oil with emulsifier and spreader sticker, which envelop, wet and smother insects and disease fungi.

    This natural pest control may be used at the DORMANT STAGE (before buds show green tissue), GREEN TIP STAGE (when leaves of blossom buds are bursting and show about 1/8 to 1/4 inch of green color), DELAYED DORMANT STAGE (when the leaves of the blossom buds are out from ¼ to ½ inch), and during the GROWING SEASON.

    Hope it helps!
