In addition to supporting the trees, bonsai soil feeds the trees. There are different bonsai soils on this page which you can purchase ready-made or you can use the recipes here to mix your own.

Professional bonsai soil is made of kiln fired clay. The firing process sterilizes the growing medium and stabilizes it so that it will not break down over time like peat based mixes will.

The resulting benefit to your bonsai trees is that they will continually receive the correct balance of air, water and nutrients.

The benefits to you are that you will never need to repot a bonsai plant just because the soil needs replacing. And you won't ever have to worry about soil compaction.

A good bonsai tree soil mixture for most types of bonsai will have a pH of between 5.5 and 6.5. Azaleas and other acid loving plants will prefer a bonsai soil mixture with more peat in it.

To please these plants, you can add peat moss to a ready-made bonsai tree soil or mix the following:

Acidic Bonsai Potting Soil

  • 1 part compost
  • 2 parts Lava Rock Granules (for drainage)
  • 5 parts peat
  • All Purpose Bonsai Soil Mixture

    This is what all juniper, pine, cedar and cypress bonsai trees should be potted in. These plants prefer a drier soil than most other bonsai tree species.

  • 1 part compost
  • 2 parts Lava Rock Granules
  • 1 part fine pine bark mulch
  • Bonsai Soil and Additives

    There are a few things you can add to bonsai soil mixtures to make them more nutritious or more moisture retentive. Add the bone and blood meal sparingly. A teaspoon added to a quart of soil will be enough.

    Crushed Shale: This can be added to the homemade soil mixes above to make them more stable and to increase both drainage and moisture retention. It also makes an attractive "mulch" or decorative top dressing when spread on top of the soil.

    Bone Meal: An organic slow-release fertilizer used to provide phosphorous and nitrogen. This is most beneficial to flowering plants.

    Blood Meal: An organic fertilizer used to give plants a nitrogen boost. It is fast acting and can be mixed into the bonsai potting soil or into the water.

    If you find that your bonsai trees are drying out too quickly, try adding a handful of plain, unscented kitty litter to the bonsai soil mixes above.
