Sphagnum Moss


Compressed Long Strand Sphagnum moss 100g is high-quality hand-picked sphagnum moss from New Zealand. Don't let this little packaging fool you. This moss expands to 8L when soaked in water for 15 minutes. Use it all or break off as much as you need and soak it. 

Loose Premium Long strand Sphagnum moss. 35g (Enough for repotting 3-5 Bonsai in 8" pots).

Long Strand Sphagnum moss is an ideal component of soil conditioning and propagation. It is also recommended when repotting your Bonsai. Just place a small amount around the root ball when repotting and then continue as you usually would with the repotting. 

To revive the sphagnum moss, submerge it in water for 10-15 minutes and then it's ready to use. 

This premium Sphagnum moss can hold 20x its weight in moisture, making it a great way to ensure the root ball is protected from drying out and giving your Bonsai the best chance of survival during repotting. 

Sometimes called spagnum moss as well, it is the same product. 


Soil (Substrate)

Bonsai soils are usually a mixture of organic potting compost (Pine Bark or Forest Floor), Akadamapumice, lava rock in varying amounts. 

It is important for the soil have good water retention while also draining well, along with very good aeration. The quality of the soil directly affects the health, size and growth of your tree. One of the worst things you can do to your tree is plant it in regular garden soil. Garden soil hardens when it drys and can often lead to a disadvantage when growing a Bonsai. 

Soil mixtures can be purchased here, but given their weight and cost of shipping, you can also easily make your own. 


Depending on the type of Bonsai you're growing, here are the general formulas for successful mixtures. 

Deciduous Tree (Leafy and looses leafs in the fall)

50% Akadama

20% Pumice

20% Lava Rock

10% Potting Compost


Coniferous Tree (Evergreen like Juniper, Cedar)

1/3 Akadama

1/3 Pumice

1/3 Lava Rock


If you are not able to check on your Bonsai's moisture levels daily, add more Akadama to the mix. 

Given how these soils erode over time, repotting every 2-3 years is required. 


Here are some suitable replacements if you cannot find the recommended types of soil.

  • Akadama - fine fired or baked clays, some even recommend cat litter as a substitute. 
  • Pumice - fine crushed aggregates, expanded shale and vermiculite.
  • Lava Rock - This can be replaced with fine gravel or you can also look into purchasing a larger lava rock at a hardware or gardening centre and crushing it. 



One of the best and easiest ways to fertilize your Bonsai, is to add a liquid fertilizer mix when water your Bonsai's once a month during the spring/summer. If your Bonsai looses leaves in the winter there is no need to fertilize it then. If you have a coniferous tree, fertilizing the tree once in the beginning of winter and once in the middle of winter should be sufficient.
