[IBC] Hawthorn Bonsai
i had problems with Hawthorn. I have Junipers and Crab Apple. I had a few
Hawtorn in training ,but it developed this odd growth which I think was rust. Between these and the crab apples they were reeking havoc on my Junipers. Eventually I had to let the hawthorns die off. I was cutting more than it was lending to it's appeal what do you spray on your trees to control rust.

Rust in the Rosaceae is orange spots on the leaves. Odd growths are usually galls. Between these and the crab apples they were wreaking havoc on my Junipers. It is usually the other way around.

I have several small hawthorn along with my junipers
and crab apples with out problems so far. I sold the nice one over the winter holidaze to make room and get cash. It was a nice one from Carl Young. It bloomed several times but not with any consistancy. I am able to make cuttings off of crimson cloud (or is it Paul's Scarlet I don't remember) and am workng them into shohin. I made cuttings from blooming branches, which continue to bloom. It takes me about three years to get roots, but the cuttings bloom each year in the process. I have some beautifully shaped root cutting shohin starts, but have little hope of them ever blooming. Kits --- Steven Wachs wrote: i had problems with Hawthorn. I have Junipers and Crab Apple.

It is more likely a bacterial or virus infection. What kind of hawthorn was it? The English hawthorns, C. xmedia, do not seem to be that prone to our native diseases. There is something that spoils the fruit, possibly a mite, so I spray a few times over the summer with Orthenex, which contains a fungicide as well as insecticide. It is very effective in preserving the fruit, preventing rust, and also dealing with elm leaf miners on elm bonsai. Here in Zone 5, people occasionally plant 'Paul's Scarlet' or 'Punicea,' which are quite hardy. They do not seem to be bothered by anything except the fruit blight. Old crabapple varieties are much worse off.

Mealy bugs are insects and the galls are one of the symptoms of rust which is a fungus. I am not sure what you are asking

I have galls or bulb like growth on my crabs and
hawthorns. I was told they were caused by mealy bugs. You can see the bugs in their cottony mass on stems and roots (if I don't catch it quick enough) Kits --- Steve wachs wrote: Mealy bugs are insects and the galls are one of the symptoms of rust which is a fungus.

I think you have 2 different problems there. mealy bugs would need a different treatment than a rust problem , what I am getting from these threads.
