Spraying Horticulture Oil when trees are dormant.

We use the term "Dormant" oil when describing the Horticulture Oil sprayed in the spring to suffocate aphid eggs and scale.

This is a very important application in that it is organic, and does not harm beneficial insects.

Every spring I get the question, "my tree is in bud - isn't it too late to spray dormant oil".

Twenty years ago...yes,!

We still use that term "dormant" because it is far more practical to layer the bark with the oil when leaves are not in the way; however the new Supreme Oils are safe to spray over buds and leaves.
Article on newer refined oils we use.

The other question is rain, "will the rain ruin the oil application."

The oil is distributed with water as the carrier so a light rain is  not going to have an effect.

I strongly encourage using the organic oils and even warranty the tree if you have done a oil application and a systemic drench because these applications are so much more environmentally sound.
