Fly Bonsai's Professional All Purpose Bonsai Soil Mix - Premium Blend - This mix is the most commonly used and accepted mix by bonsai professionals around the world. In some circles this is known as boon mix or franks mix in the North East United States. This is the mix I use on nearly all of my personal trees. - Is It Dirt? No. Bonsai trees do not like "dirt" and will in most cases die if left in dirt over long periods of time. This is substrate. - What Is In It? The primary components are Akadama, Pumice and Black Lava. These components have been found over time to provide the best drainage, water retention, nutrient retention and air circulation possible to promote healthy bonsai.- 1/3 Japanese Hard Akadama - is a clay like component that is excellent binding nutrients, it holds water and it breaks down over time allowing roots to grown in it's place.- 1/3 Japanese Hyuga Pumice - is a volcanic byproduct that is excellent at retaining water.- 1/3 USA Black Lava Rock - is also a volcanic byproduct that is excellent at promoting air to the root area. Black lava also adds structure to the soil.- Horticultural Charcoal -This was added to harbor beneficial bacteria and add humic acid in the soil. - Particle Size - This is very important in a soil mix. This blend is sized from 1/16" to about 1/4" in size. This allows air to the roots while maintaining moisture needed by deciduous trees. - How Do I Use It? This is "real" bonsai soil. Be sure your bonsai pot has holes in the bottom covered by bonsai mesh. Each micro climate may require different amounts of water. On very hot/dry days you may need to water two/three times while around freezing you may need to water every week or two. Push your finger 1" into the soil and feel for moisture. If it is dry, it is time to water. Paying attention to your bonsai's moisture level is very important. When potting into a new mix, the tree will use water at a different rate and the soil will dry at a different rate. Pay Attention! Also, be sure to repot at the proper time of year for your climate and type of tree. Lawn & Patio, Superfly Bonsai, Professional Bonsai Soil Mix - Premium Blend- 12 Quart.
