How to Use Coffee Grounds for Tree Fertilizer

Trees are a staple for any landscape or garden, whether they are fruit, nut or oak trees. Trees require care and maintenance in order to boost their growth, just like any other plant. One of the key elements that encourages growth is fertilizer that is high in nitrogen, phosphate and potash. An easy fix to this (and an organic one) is to use coffee grounds right from your kitchen. The grounds act as a natural fertilizer, and using them for this process requires few materials and little time.

Store household coffee grounds from your coffeemaker in an old coffee can or other container, such as a bucket. Starbucks even offers bags of used grounds to customers for free. You will need about 1/2 pound for 1 tree.

  • Trees are a staple for any landscape or garden, whether they are fruit, nut or oak trees.
  • Trees require care and maintenance in order to boost their growth, just like any other plant.

Combine 1/2 pound of coffee grounds (per tree) with 5 gallons of warm water in a bucket, stirring it slowly and carefully to completely combine. You are basically creating a fast-acting liquid fertilizer.

Put on your gardening gloves. Use your hands to layer the fertilizer around the base of the tree when it is young, and also in the spring and fall seasons.

Sprinkle used coffee grounds that have not been mixed with anything else around the base of your trees before rain or watering, for a slow-release nitrogen fertilizer.

Tip

You can also mix the coffee ground fertilizer into soil for houseplants or new vegetable beds. Circle the grounds around the base of plants along with eggshells to repel pests.
