AusBonsai

Now I'm living in a place that has wet winters instead of dry ones, it occurred to me I should be using lime sulphur on some of my trees to prevent issues when they leaf out. I bought some mainly to put on the roses after I cut them back hard for winter, but in truth I know nothing about it. Can it be used on all trees? Or do I need to separate my maples from my boogies etc?

Diluted you should be able to spray all deciduous trees. I'm not sure about evergreens though?
I've often seen caution advised to cover the pot when spraying so not too much gets onto the soil. I don't know whether this is another old bonsai growers tale with no substance but can't hurt to be careful unless you know better.

The Japanese seem to dip their bonsais rather than spray, so I guess that stops too much getting on the soil...?

When spraying I usually cover the soil as previously mentioned, AND the pot as it will turn a nice unglazed brown pot colour to a ghostly pale.
I also use it to spray my wooden benches that the plants sit on, for any little overwintering pests that may be lurking in crevices etc.
(I actually think the smell is enough of a deterrent for anything that has a nose.)

I spray everything in winter including conifers and evergreens with no ill effect.
