Chojubai Notes: Part 3 Why is my weak Chojubai

Few plants come without a perplexing problem or two. For dwarf flowering quince ‘Chojubai’, the most serious problems are in the roots. Chojubai are strong plants that normally extend 6 “(18”) by wave of growth. If it is not, then, be alert.

A weak tree will not cause the typical extensions of spring and could have a yellowish color. Some are simply weak Chojubai in soil that is too thin, is overwatered or underwatered, or are in pots that are too shallow, and they are easy to correct.

Otherwise the root zone of a Chojubai is susceptible to various problems that can weaken your tree. The first is a nematode, the second is a bacterium, and the third is a root galls and are all separate but interrelated of the disease known as crown gall pieces. it is not common, but if you have a Chojubai, be aware of general weakness. I’ve been looking at this problem for a while, and my apprentice Bobby has been very helpful to discover some of the links also, so I would like to offer here what we are doing now to address these underlying problems.

  • In brief summary, nematodes injuries root cause wounds in the fine roots of the Chojubai that provides an entry for bacteria, a real rascally Agrobacterium tumefaciens, that gill cause of the crown. A wound from a root pruning tool can also provide input. The bacteria live inside the root, and transfers part of its DNA into the DNA of plant cells, which, with cell division, causing galls callus-as we see in the roots of affected plants. So the bacteria is very clever guy, not too easy to get rid of!

First, there was a nematode called … Nibble.

… then it was not a bacterium called … WisFree …

… and Finally there was a vesicle called … warty. And everyone had a rockin party on his boat. Read on to find out what Mickies to throw in their drinks …

If you see galls (warty and friends) in the roots of Chojubai, try these treatments:

  1. Move the tree in a larger pot. If the weakened Chojubai is in fine soil, a small pot, compacted soil, or a shallow pot, certainly transferred to a larger, deep bowl or box with thick pumice (1/3 “+ size) or similar the bottom and sides surrounding the original soil mass. are allowed to grow freely, without excess water (algae and liver are tracks), while controlling the other matters.
  2. control nematode root injury. There are specific nemacides to control nematodes, and these can be used. with a suggestion of a friend and a couple of tests found that soaking the rootball in Zerotol 1.25 oz / gal will kill nematode. this can be done while the tree is still in the pot.
  3. Control of bacteria. the problem with bacteria is that there are within the same root. copper is effective for this bacteria (Japanese bonsai professionals use streptomycin, but it is disconcerting to calculate the appropriate concentration for plants because they are made for internal use with animals). I’ve been using Phyton 35 is a systemic copper bactericide / fungicide. Be sure to carefully read the label Phyton-35 requires a change in the mix it in water to a pH of 5.5-6.5.
  4. Control of the gallbladder. Cut the gall away with pruning shears when transplanting. It may take several repottings to get all the gall eliminated.

What seems to be important is to take care of this three-ring circus systematically. First remove the nematode. Then go after bacteria. And finally cut the gallbladder. Even if you’ve killed your nematodes and bacteria, you may have the guts as the DNA of bacteria replicate keep cell division. But if you’ve killed the nematode and is controlling the bacteria, it weakened Chojubai often shows a very quick jump back to strong growth. I have seen new, big, strong and even outbreaks Chojubai leaves in a completely stagnant in less than two months with these treatments.

The nematode is often the main culprit, who seem to think that Chojubai roots are like crack, chocolate, nirvana, or all three. They can knock down the root system of a quince fairly quickly, and then see a weakened tree with roots gimpy system that does not have the typical force of Chojubai. Many other plants Rose family are particularly tasty to nematodes.

Some of the nematodes can be seen without a magnifying glass (I saw some of about ½ “long, and resemble glassy worms), others are almost microscopic. If you find that the gallbladder can assume that have bacteria. it is best to prevent, for example, be careful sterilization of cuts, and nematode control.

hope you can never see more guts on your tree, but if you do, try these solutions to bring your tree back to health
