Tools Needed

Bio Advanced Month Tree & Shrub can be applied with a hand sprayer or backpack sprayer. You will also need a flexible measuring tape to measure the size of the tree and/or shrub.

How to Use

• Step 1: Measure the size of the tree or shrub you intend to treat to determine how much product you will need to use. To do this, measure the distance around the tree trunk or the height of the shrub. Measure distance in inches around the tree trunk at chest height, and multiply the number of inches by 0.5 to find how much product you need. If there are multiple tree trunks, add their measurements together, then multiply by 0.375. For example, if one tree has four trunks and they measure 20, 10, 5 and 5 inches or a total of 40 inches (40 X .375 = 15 ounces of product to use). For every half ounce of product used you will want to mix it with 1 gallon of water. If your tree trunk exceeds 50" then use 2 gallons of water. For shrubs, you will use 1.5 fl. oz. per foot of shrub height.
• Step 2: To mix, you will want to fill your sprayer halfway with water, add the required amount of Bio Advanced 12 Month Tree & Shrub needed, then fill the rest of your sprayer with water. Close the lid and shake until mixture is even.
• Step 3: Slowly apply the spray mixture as close to main stem of the trunk or shrub as possible. You will want to apply your solution evenly around the tree or shrub.
• Step 4: Refill the sprayer with clean water and pour around the trunk of the tree or stem of shrub.

Where to Use

Bio Advanced 12 Month Tree & Shrub is to be used on non-crop or ornamental trees or shrubs distanced away from water.

When to Use

Bio Advanced 12 Month Tree & Shrub can be used anytime of the year, preferably on dry or humid days to avoid the ground being waterlogged or frozen. For best results, the spray mixture will work best in the fall when insects are less active. During prolonged dry periods, you will want to water the tree or shrub well the night before application.
