FERTILIZER: ORGANIC VS SYNTHETIC



In common with all plants, your bonsai need three basis nutrients: nitrogen, potassium and phosphorus.  Also in common with other plants, they don't know (nor do they care) whether these nutrients are derived from decomposing vegetable and animal matter (organic) or from the production line of a giant chemical plant (synthetic). 

So why all the fuss about using organic fertilizers? Consider your bonsai, its container and the soil as a single, self-contained unit, and compare that to a tree growing in open ground.  A bonsai's roots are confined in a small container, they are growing in a virtually inert and lifeless medium where they rely on you for all their needs - and their needs don't stop with the basic NPK of synthetic fertilizers.  The soil in open ground contains many other minerals and countless zillions of microorganisms that perform a myriad of functions necessary to keep the soil healthy and vibrant. They help the plant build resistance to stress, they aid the roots in absorbing major and micro-nutrients, and they help to prevent compaction and stagnation of the soil. Your plant may not care about the type of fertilizer you use, but the soil, and it's microorganisms do care - a lot! 

It's rather like asking a human to survive on burgers and chips - it can be done for a while, but eventually the effects of an imbalanced diet would cause deterioration and probably death.  Container-grown garden plants generally only spend a few years in a pot, so the long-term effects of inorganic culture are not so much of an issue. But your bonsai, we hope, will live for a very long time in a container, and will be asked to withstand surgery and assault, so it becomes more important to give them the best possible growing conditions. 

Most organic fertilizers, not only contain many of the important microorganisms, but they also contain the substances necessary for them to multiply and function, creating a truly living and healthy subterranean environment for your bonsai's roots. They also contain many trace elements, or micro-nutrients that are essential to overall plant health (something that even the best bonsai soils lack). These micro-nutrients are broken down by the microorganisms and converted to a form that the plant can absorb readily. Once the nutrients have been depleted, the microorganisms remain to do their important work until the next application of fertilizer.  Month on month, year on year, the soil and the tree become healthier.

Within a few weeks of changing from a synthetic fertilizer to organic, such as Green Dream, you will notice the difference: your trees will seem happier, more vibrant. Foliage will be brighter, buds will be stronger and growth will be more consistent.  After a few weeks they will become less miserable in periods of environmental stress such as heat or drought.

Within three months of discovering Green Dream I was absolutely convinced that it was the best feeding regime for my bonsai. I have never regretted the change and I can thoroughly recommend Green Dream as the mainstay fertilizer for all bonsai growers.
