After being sprayed 10 days ago together with many Patersons Curse and other herbaceous weeds, mapped with Field Maps / Treated Weeds / Herbaceous Weeds, all trees in the area of the large drainage line have a weedy nutrient loving plant ground cover

sorry Mike I find spraying, mapping and taking photos a bit overwhelming at times; I thought it is still worthwhile to document a couple of the trees (Eucalyptus and Exocarpos) with weedy ground cover; I think the picture shows the weeds restricted around the tree
