mugo # 36

The old needles were removed and the wire taken off, the whole tree was treated with biotreecleaer. Now it looks fine. But it will have to be wired a second time soon.
Second image as of 2002, right after collecting.

Would you be so kind and tell a few details about this biotreecleaner? What exactly is it for? Where do you get it? Is it standard practice of yours to treat trees with it from time to time, or were there any particular reasons to do so?

BIOTREECLEANER - ENGLISH

biotreecleaner is a liquid which cleans bonsai thoroughly without harming the bark or the health of the tree. Green stuff like algae or moss will be removed dependably. Dirt will be burned by the acid. A fresh original color of bark will appear on most trees. e.g. Larches and pines will get nice brownish bark instead of dirty gray-black. In case one does not like the new look just do nothing for a couple of months and the former color will come back. Biotreecleaner sterilizes the surface of the tree. Bacteria, fungi and insects are impaired strongly. Biotreecleaner bleaches deadwood and also bark to a certain extent. So it fulfills the functions of of lime-sulphur in addition to removing green stuff thoroughly. Only the deadwood does not look like painted white a t all afterwards, but rather a natural color and texture of deadwood will appear. Some bonsai enthusiasts use biotreecleaner instead of lime-sulphur. The impact of biotreecleaner will last for a few months. During a vegetation period it is typically used twice or three times. Ordinary remover of green stuff as they are available in garden centers are typically not for usage on living plants. The 'bio' in biotreecleaner stands for application onto bonsai from the surface roots up over the trunk and deadwood into the fine branches, without this being harmful for the tree. Biotreecleaner has been tested on several hundred bonsai for a couple of years. Many of these trees were high class and some world class. The liquid has worked well in all cases and no immediate or long-term harm has been noticed.
Application of biotreecleaner:
It is possible to paint biotreecleaner onto a dry tree. But it is better to make the tree wet by spraying ordinary water onto it before. Then you paint onto every part of the tree with a large painter's brush.
You can, of course, only paint onto deadwood and all spots which are green or dirty. In daily work it is better to paint everything from surface roots upwards into every little branch. When the outside temperature is 25° C or warmer biotreecleaner works very quickly. First results are visible after a few hours and the effect continues for many more days. When the outside temperatures are low the effect is only visible after a day or even several days. The final effect is only visible after several weeks, but then it is amazing. The tree should not become wet with rain or watering right after application of biotreecleaner. Otherwise the acid will get onto the soil surface. This is not necessarily detrimental, but the moss will certainly be dead. If you want to be save, cover the soil surface with cloth or paper. When bitotreecleaner has dried on the tree surface once the tree can become wet again without problems. So it is OK to water the whole tree or to let rain hit it after a day. It is possible to clean the pot surface and kill all green stuff. In some very rare instances with higher concentrations the glazing can change color permanently though. After having applied biotreecleaner wait a couple of days and see the result. If there are still some green or dirty areas, apply there again. You should not overdo it and avoid getting too high concentration of this acid though. It is possible to spray the liquid onto the whole tree if there are no leaves or if the foliage is hard. Add water to it before spraying to have a lower concentration of salt. It is not necessary to protect the soil when spraying with low concentration in the field. The acid will be neutralized quickly when hitting the ground..

Safety considerations:
Biotreecleaner is an acid. It can be harmful for humans or animals. Try to avoid contact to skin. Never let it get into open wounds or mucosa and certainly not into the eyes. Absolutely avoid swallowing. If biotreecleaener gets onto normal skin just wash off with regular water. No harm will be done usually. If it ever gets into open wounds, mucosa or eyes, wash off immediately, put your eyes under water in a bucket and open them. Bes sure to store the bottle away from children and strangers. When applying with a brush use gloves and protect your face. When spraying, protection of hands and face is absolutely necessary. Do Not inhale when spraying. Biotreecleaner is deadly for algae, moss and small critters already at low dosage. If applied on trees onto bark and deadwood it is save. On small branches with green bark it sometimes can hurt a bit, but usually there is no harm. If it touches leaves or needles as a rule the is no harm. Sometimes small permanent changes in color can occur. In higher concentration it can permanently change color of pot glazings slightly. If it drips onto pots, clean with normal water quickly. Clothing that gets into contact with biotreecleaner will often bleach permanently. It is a good idea to add normal tap water to your bottle of biotreecleaner to have a lower concentration. If water evaporates, higher concentration of salt are the result and it will become more aggressive. Everyone is responsible for save application and storage. No liability can be accepted for improper usage.

Does any back-budding occur on these collected pines? The crown appears so much more compact. I know wiring techniques and such allow you to make the tree more compact, but in the image in 2002 the tree has long-thin branches with growth only on the ends.
The progress and transformation of your trees amaze me and are never disappointing.

The compact appearance is partially due to styling tricks. But there is also considerable back-budding on such collected trees.
The secret; modern substrate, full sun, lots of water daily, lots of feeding with strong nitrogene content.
