Understanding Tree Plant Sealer: What is it and What is it Made of?

Tree planting is an important aspect of sustaining a greener environment. However, it takes more than just putting the plant on the ground to ensure its survival. One of the essential tools necessary for tree planting is the tree plant sealer. This article explains what tree plant sealer is, and the different materials that make it.

What is Tree Plant Sealer?

Tree plant sealer is a mixture of materials applied on the roots of a planted tree to prevent stress, increase water absorption, and lessen the likelihood of pest infestations. Mostly, it's a thick, tacky compound that slows down the drying of roots and helps to prevent the entry of pathogens into the trunk.

The primary purpose of using a tree plant sealer is to create a physical barrier preventing waterlogging of the soil around the roots of the tree plant. Tree roots need oxygen to survive, and excessive moisture prevents the roots from getting adequate airflow. Therefore, tree plant sealer acts as an aid in retaining moisture and eliminating air gaps that cause tree transplants to struggle.

What is Tree Plant Sealer Made of?

Tree plant sealer materials differ from one manufacturer to the other. However, there are various standard ingredients that are mostly used. They include but not limited to:

1. Asphalt Emulsion

Asphalt emulsion is a black, viscous liquid byproduct of petroleum refining. It is a handy material that has been used in producing several building and construction supplies. In tree plant sealers, it forms the base and used as a water-resistant adhesive which holds the other additives together.

2. Policarboxylate Polymer

This is a water-soluble polymer used in making tree plant sealers that are more durable than regular asphalt emulsions. It helps to improve the viscosity, elasticity, and strength of the sealer, making it resistant to environmental elements and pest infestations. Policarboxylate polymer allows the tree to grow as it fills in air pockets found in the soil, allowing the roots to establish themselves more quickly.

3. Mineral Fiber

Mineral fiber materials, such as rock wool, are added to give the sealer a thicker consistency, making it easier for application. The fiber strengthens the sealer against harsh weather elements and erosion, which can dislodge the tree planting compound.

4. Proprietary Additives

A manufacturer's proprietary additives are added to the sealer to give it specific characteristics. For instance, some brands add a bright color to the sealant, making it easier to identify trees that have received the treatment. They also improve the adhesion of the sealer to the plant's stem, which reduces the risk of fungal, pest, or bacterial infestations.

How to Apply Tree Plant Sealer?

The application of tree plant sealer is a straightforward process. If done properly, the sealant can last for up to two years.

The following are the steps on how to apply tree plant sealer:

1. Dig a Hole

Begin by digging a hole twice as big as the plant's root ball. Make sure the hole is deep enough to cover the top roots. Consequently, backfill the hole with enough soil to hold the tree in place.

2. Apply Tree Plant Sealant

Squeeze the sealer into the lower roots of the tree plant. Apply it evenly around the plant in small amounts, working up the trunk, ensuring you don't get it on the leaves. The sealer should be applied thoroughly and should have a thickness of 1/8th to 1/4th inches.

3. Water the Tree Plant

Ensure you water your newly transplanted tree to help the soil settle around the roots.

Conclusion

Tree plant sealer is an essential tool for ensuring during the early period of a newly planted tree's life. It protects the plant's root system from the harsh effects of natural elements, such as erosion and pests. With its main ingredients being asphalt emulsion, policarboxylate polymer, mineral fiber, and proprietary additives, tree plant sealer provides an excellent protective barrier for the longevity of the tree plant.
