For over a century, Japanese bonsai artists have used an organic fertilizer to provide the nutrients needed to keep their trees in perfect health year round. BonsaiBoost is locally produced from high quality, pure canola meal, the same ingredient still used in Japan today. BonsaiBoost should be used on any bonsai or potted plant, from collected stock through to exhibition trees and on flowering, fruiting or evergreen trees. Easy to use with no mixing required, BonsaiBoost sachets are laid on the surface around the bonsai and watered as normal. At each watering, a little of the nutrients in the sachet is carried to the roots. Sachets can be replaced every 2 months during the growing season.
The above claims are guaranteed. If you are not 100% satisfied we will refund you in full.
BonsaiBoost is packaged in high quality coffee filter bags to ensure water penetrates easily but without allowing the ground fertilizer to disappear into the soil mix.
To use simply place the BonsaiBoost bag onto the soil and secure in place with wire or a toothpick. For shohin (small trees below 30cm) you should use about 1 bag. Medium sized trees can take 2 bags and larger trees as required. For maintenance of developed trees you will not need as much fertilizer as trees which are still being developed.
Replace the bags roughly every 2 months. When you first start using them they will omit an odour. This odour diminishes with time till eventually no smell is experienced. The ground canola cake will become a solid lump, this is normal.
While using BonsaiBoost little additional fertilizer is needed. For many years, Japanese bonsai professionals have been using exclusively these cakes to fertilize their trees. However for flowering plants you may want to use a fertilizer specifically aimed at promoting flowering. A seaweed extract may also be a good idea to use once in a while.
BonsaiBoost is the ideal fertilizer when using open growing mediums such as our Professional Bonsai Growing Medium.
After using the bag for your preferred length of time don't simply throw it away. You can do the following:
