When to trim & Feeding a Jane MagnoliaJust infor on aJane Magnolia?
Answers: Glenn has lied to you.
Jane Magnolia (Magnolia x liliflora) will set it's flower buds contained by the late summer or leak of the year, for the next season. So pruning within the fall would within effect cut off the flowers that it might own in the spring. In short, that would be a disaster. Instead, trim the magnolia contained by the month or so following it's bloom. Thin out some of the branches to allow for some air circulation, and drop off the size as desired. Don't cut more than 25% of the plant in one season. Follow that up next to an organic fertilizer, such as ESPOMA hollytone.
Japanese snowball plant... hmm, that's tricky, because the adjectives name doesn't assistance me. I think you might be asking more or less Viburnum opulus 'Roseum'. That would follow the same proposal as the magnolia. Trim it right after it's done blooming. You might be able to be somewhat more aggressive with your pruning on this plant, but I wouldn't recommend going too severe.
I hope that this help
Good luck-
both should be trimmed in winter and feed in spring
