| I've had this little tree for probably 6 or so months, and ever since I got it, it has not put out any growth. It hardly has any growth on it. It is severely rootbound, as I see roots poking through the bottom of the pot. I want to maybe repot it, and I was also wondering if anyone else had any advice or criticism toward this tree. Please, be as drastic as you feel necessary. This tree just does not appear to be growing at all. And maybe it is due to the lack of room to grow. Should I repot it? Also, the rock it is planted "over" (it really goes through it) is looking rather bad. It is a red lava rock, but it appears white and old looking. Well, here is the tree:
Thanks! Ryan |

| Ryan,iwould repot the tree into better soil.first the white on the rock is probley salt deposits from watering.. mix dish soap and water and with a toothbrush clean it best you can.i would trim the small roots from the rock leave all the large ones they are your feeder roots.where is the tree located inside or out??? put it outside let it get use to the sun.hope this helps john |
|
| Um.. actually the newer, smaller and highly placed roots are the 'feeders'. The older, longer ones may have new feeders on their bottoms, but you don't want to encourage those, but the ones higher up. You can't obviously just cut away all the older long ones, but find a better balance. |

| I won't cut anything just yet. I did repot this today. Here are the pictures:

| You did well not to cut anything off. Soil looks a lot better too, hope you didn't mess around wit dish soap though. Now leaf the tree on a shady place where there's no wind for at least a month and DO NOT FERTILIZE. Only fertilize trees that are healthy. Good Luck! |

| Why would you say "DO NOT FERTILIZE. Only fertilize trees that are healthy." Many trees are 'sick' because of nutritional deficiencies. To adhere to the above advice and not fertilize them is to condemn them all to death. Trees that are not growing are dying (Dr Alex Shigo), and trees need a full compliment of nutrients to grow. Bonsai soils are generally an extremely poor source of nutrition, requiring frequent and regular supplementation. It's not as though the scheff shown has a vast amount of energy reserves to make roots. The tree is already running on empty, and to deprive it of the building blocks required for the tree to make food and grow doesn't seem like a very good idea to me. Al |

| A tree needs nutritions to grow, that's true. But a shortage of fertilizer will only make it grow less figurous. It will take a very long time before the tree really starts to dimish due to a lack of nutritions. Trees become sick because of damaged rootsystems. Damaged rootsystems may be caused by many things like too much water, too less water, a buildup of toxins from excessive fertilizing etc. Etc. But definitely not by a shortage of nutritions. Fertilizer is NOT a medicine! In order for a tree to recover, it needs to revive it's rootsystem. Therefore a good clean soil is necessary. Adding fertilizer to the mix burns any new forming roots right from the start giving the tree no chance to recover it's rootsystem. This will only make things worse! |

| Let the tree recover for a mont or two. Just like you would never fertilize a tree after repotting, one should never fertilize a stressed tree. You could however add some vitamins and hormones like superthrive or rainbow to stimulate rootforming. http://www.gardenguides.com/100377-save-sick-tree-weed-killer.html |

| "Adding fertilizer to the mix burns any new forming roots right from the start giving the tree no chance to recover it's root system. This will only make things worse!" You seem so sure. ;o) Sorry - but you'll have much difficulty supporting this idea. There is no scientific basis for it. You CAN over-fertilize, and induce plasmolysis (fertilizer burn) but that is unrelated to this discussion because it affects plants in the same manner, whether they are newly repotted or not. Fertilizing at normal rates (normal TDS/EC levels) will not burn even the tenderest newly emerging roots. I'm very familiar with what fertilizer is/isn't, and that it is not medicine or plant food, but thanks for the primer. ;o) The simple fact is that if adequate nutrition is not available to the plant, it cannot grow (do a search for "Liebig's Law of the Minimum"). YOU may think it's growing because it is translocating (only the) mobile nutrients from plant parts it is shedding to make new leaves and extend branches, but growth is measured in the increase in biomass, and biomass cannot increase unless all the nutrients are available. Trees become 'sick' for a wide variety of reasons - not just a compromised root system. Disease, insects, drought, heat stress, nutritional deficiencies/toxicities, pollutants, herbicides .... are a few causes, making it too simplistic to simply announce that trees become sick because of damaged root systems - as if it's the only cause. You can also be assured that nutritional stress (deficiencies) affects all organs of the plant, including the roots. Al

| ""and DO NOT FERTILIZE. Only fertilize trees that are healthy."" I can't belive I'm reading this. JoJo |

| You both seem to misunderstand the difference between nutritions and fertilizer. Fresh soil (even bonsai soil) contains more then enough nutritions for a tree to grow (Although minimum growth Liebig confirms). But it does not contain fertilizer. Fertilizer, either produced chemically or organic contains chemicals that produce nutritions for the tree. It does not contain nutrition itself! These chemicals are harmful for newly formed roots. That's why the most respected advice is not to fertilize trees after repotting, and never fertilize stressed trees. A sick tree can be caused by many things as is mentioned before. But it always, always affects the trees root system. A tree does not become sick if it has a healthy root system. Therefore restoring the root system is vital for recovering the trees health. google: fertilize stressed bonsai trees. Result: Oh, and most importantly: Go ahead, go against the advise of the greatest bonsai masters like, Graham Potter, Lindsay Farr, Masahiko Kimura, Walter Pall and gardenwebs own FAQ page. I don't know who wrote it, but he's surely more experienced than you two. P.S. Liebig is Only about healthy trees and about nutritions, not about fertilizer. |

| Sigh. "Fertilizer, either produced chemically or organic contains chemicals that produce nutritions [sic] for the tree. It does not contain nutrition itself! These chemicals are harmful for newly formed roots." Fertilizer contains nutrients the plant uses as building blocks to make its food and to keep its systems orderly. If fertilizer doesn't contain nutrients, where do they come from? Why are N,P,K,Ca,Mg,Fe,S,Mn,Z, and others (contained in fertilizers) listed EVERYWHERE as nutrients? .... and since when are nutrients harmful to newly formed roots? Who says Liebig's law only pertains to healthy plants? I've never seen that exclusion or qualification, so if you want us to believe your theory, you'll want to link us to something that supports your idea. Read the link below. Brent is well respected in the bonsai community for his expertise. You'll see you are at odds with not only me, but with him as well. Perhaps you should let him know he's misguided, too. ;o) Take care. Al |

| Al... you put it so well, some things should appear above the forum as permanent FAQ's! |

| larke, I totally agree with you! I recently moved trees that were going down hill fast into new soil and used fertilizer. Now they are green and happy! dsdevries, Al~great article! |
