How to Feed Your Tree for Healthy Growth

Proper tree care starts with healthy roots. Knowing when and how to feed your tree can help it establish strong roots and grow well. Natorp’s tree-growing experts share these simple tips for caring for newly planted and established trees.

When Should You Feed Your Tree?

Early spring is generally the best time to fertilize trees as new growth begins. Some trees may benefit from fall fertilization, depending on their health, soil conditions, and local climate.

Before applying fertilizer, make sure your tree needs it. Healthy trees growing in good soil may not need additional fertilizer.

How to Feed a Newly Planted Tree

Newly planted trees need time to establish their roots. Instead of using a strong fertilizer, consider a root stimulant, such as Bonide Plant Starter, to support root development.

• Bonide Plant Starter: Mix with water as directed on the label and apply around the tree’s base.
• Espoma Bio-tone: Mix into the soil when backfilling the planting hole, following the product directions.

How to Feed Trees Planted 1–2 Years Ago

Trees in their first two years are still developing their root systems. Focus on proper watering and maintaining a layer of mulch around the tree.

If your tree needs additional nutrients, use a fertilizer suitable for trees and follow the product label directions. Avoid overfertilizing, which can damage roots.

How to Feed Established Trees

Established trees may not need fertilizer every year. If your tree shows signs of poor growth or nutrient deficiency, a soil test can help determine whether fertilizer is needed.

If fertilizing is recommended, choose a suitable product and apply it according to the label directions. Avoid applying lawn fertilizer near trees unless it is appropriate for their needs.

What Is Vertical Mulching?

Vertical mulching can improve soil conditions around established trees, especially in compacted soil.

The process involves creating small holes around the tree and filling them with suitable materials to improve air and water movement. Because this method can damage roots if done incorrectly, consult a tree care professional before attempting it.
