My Jane magnolia has scale. It is under 5 feet tall and pretty small. If I scrape the scale off and apply a fungicide with a paint brush, will that save my tree? The green “lawn” is crab grass and clover because the grubs ate everything. We began treating the yard with grub killer…milk spores; the stuff you use 3 times a year for 2 years. Since the grass is gone I want to have a pollinator yard. Can I plant wild flowers and native grasses now or do I need to wait until the treatment cycle is complete? Any and all information is greatly appreciated. Thank you Jill Fitzpatrick
