I planted many different flowers under this little tree last Spring after painstakingly yanking out grass roots. I was rewarded (?) for my efforts with Blue Scarlet Pimpernel plants everywhere! Please tell me what to do next Spring so I have some control in that space.

?😕??? What is your goal ?
Sounds like some round-up is in order, like, right now. Im i right ?

Round-up is the spawn of the devil. My garden is totally sans man-made chemical weapons. Thus, I pull and pluck. (I have a wry humor in case you think I'm serious) But I make crossed fingers in front of the Round-up shelf. But thanks for answering my question.
