A Planting Mix and a Mulch in One Bag

Kellogg Garden Organics Gromulch is a 2-in-1 organic planting mix and mulch recommended for trees, shrubs, roses, and flowers. You can use Gromulch as a soil amendment to add a boost of nutrients to your trees, shrubs, and groundcover. It helps loosen compacted clay soil and adds rich organic material that creates the right balance of moisture retention and aeration for strong root growth.

You can also add Gromulch on top of the soil around trees and shrubs as a nutrient-rich organic mulch, keeping the soil cool and moist while it slowly releases nutrients into the ground. Whether you use it as a soil amendment or as a mulch, Gromulch is made from natural ingredients and safe for your family and pets to be around.

How to Use Gromulch

  1. For New Trees, Shrubs, and Flowers: Mix Gromulch into the planting hole at a ratio of about 1 part Gromulch to 2 parts native soil. One 2.5 cu. ft. bag transplants 6–7 one-gallon plants or 4 five-gallon plants.
  2. To Enrich Existing Beds: Spread Gromulch over the bed and work it into the top few inches of soil. One 2.5 cu. ft. bag amends 10 sq ft at a 3-inch depth.
  3. As a Top Mulch: Spread a 2 to 3 inch layer around the base of trees, shrubs, and flowers. Keep the mulch a few inches away from trunks and stems to prevent rot.
  4. Feed Through the Season: Pair with Kellogg Garden Organics All Purpose Fertilizer for steady plant nutrition.

Key Benefits:

Skip One Trip to the Garden Center

One bag enriches planting holes and tops your beds, so you don’t buy soil and mulch separately.

Plantable Clay Soil

Loosens compacted ground so roots can spread and water can move where it needs to go.

Soil That Stays Cool and Moist

Using Gromulch on top slows evaporation and feeds the soil as it breaks down.
