What makes my Katsura leaves turn brown? Every summer after the leaves have come out, it isn’t long before all the leaves are turning brown. I first thought it was a fungus so I sprayed it with a spray for brown spot and tree disease that did not help. Then I sprayed it an insecticide in case it was caused by insects, that did not help. I really need help or I’m afraid I will lose it.
Make sure your tree is planted properly, not to deep.
A little bit of shade protection is the perfect spot to plant.
Mulching is helpful.
Here is a link to refresh you on the care requirements.
Pruning to repair it's shape may take some time over a few seasons.
Here is an article that may help you.
May I ask you, please, if you could advise what size I can expect a Katsura Tree (Cercidiphyllum japonicum) to grow to? I have just ordered one, and was advised that it is ideal for small or large gardens or for bonsai – I would like to keep it small but not bonsai size!
The size at maturity can be 40 to 60 feet tall and 20 to 50 feet spread. It takes 40-50 years or more to reach that size.
It is difficult to control the size of a tree, but there are some smaller varieties of Katsura Tree. The size will probably depend on the site and the variety you have. If many shrubs or other trees are planted nearby, it might end up smaller than if it was alone.
I have 5 Katsura trees and wanted to plant them on the west side, which is pasture, for shade along a fence row. After reading that they need water every day for a year, would planting them close to our pond be better?
I would say a new Katsura tree really only needs daily watering during drought conditions. After the first week, you can water more like once a week, as long as the soil doesn't get excessively dry around the tree. Water deeply each time, and it should do fine.
We planted a young weeping Katsura (Cercidiphyllum japonicum pendulum) .
It is now about 8 feet tall. All top branches are hanging dowm.
We would like to get it taller.
Do we need to bend one of those hanging branches upward and tie it to a stalk or will the tree sprout an upward reaching branch iitself.? Many thanks,
It will get taller slowly over time. As the lower branches die, or get cut, they will sprout more, and this stacking effect will make it taller over time. There is nothing required, outside of letting it be natural, and pruning off dead growth.
There appears to be a stem canker (from a fungal or water-mold infection) at the base if the primary stem. This is most likely a result of over-watering from the lawn surrounding the tree.
The infection may originate in the roots and root crown below the soil grade. Therefore cutting out the primary stem may not stop the infection from affecting the remaining stem. At this advanced stage of infection it is difficult to stop it. You may lose this tree.
Trees and grass have different water needs and the trees often cannot tolerate the frequent watering that lawn grass requires.
