How to Winter Wash Trees: A Step-by-Step Guide

Winter is a great time to give your trees some TLC. One important task that you can do during this season is winter washing, which involves removing pests and diseases from the bark and branches of your trees. In this article, we’ll take you through the step-by-step process of how to winter wash trees to keep them healthy and strong.

What is Winter Washing?

Winter washing is a traditional horticultural practice that has been used for centuries to control pests and diseases on fruit trees during their dormant season. It involves spraying a mixture of water, soap, and oil on the tree’s bark and branches to kill off any insects or eggs that may be hiding there.

This technique is particularly useful for fruit trees, as it helps to prevent pests from damaging the fruit and spreading diseases to other parts of the tree. However, it can also be used on ornamental trees to keep them healthy and free from pests.

When Should You Winter Wash Your Trees?

The best time to winter wash your trees is during the dormant season, which is typically between late autumn and early spring when the leaves have fallen off and the tree is not actively growing. This is because pests are less active at this time, making them easier to manage.

You should avoid winter washing your trees during freezing temperatures, as the soap and oil mixture can freeze and damage the bark. It’s also important to choose a dry day with little to no wind to ensure that the mixture sticks to the bark and doesn’t blow away.

How to Winter Wash Your Trees

Here’s a step-by-step guide on how to winter wash your trees:

Step 1: Prepare the Mixture

Mix together one gallon of water, one cup of horticultural oil, and two cups of liquid dish soap in a large bucket or sprayer. Stir the mixture gently to combine the ingredients, being careful not to create too many bubbles.

Preparing the mixture. Mix oil, water, and soap.

Step 2: Apply the Mixture

Using a garden sprayer, apply the mixture to the tree’s bark and branches, making sure to cover all surfaces thoroughly. Be careful not to spray too close to the tree, as this can damage the bark.

Spraying the mixture. Apply to all surfaces of the tree.

Step 3: Rinse the Tree

After applying the mixture, rinse the tree with clean water using a hose or sprayer. Be sure to remove all excess soap and oil from the tree’s surface to prevent damage.

Rinsing the tree. Be sure to remove all excess soap and oil.

Step 4: Repeat if Necessary

If you notice any remaining pests or disease on the tree after the first application, repeat the process as necessary to eliminate the problem.
