Hello! Very new gardener here with established landscaping I have no clue how to care for lol. Two questions.
1 - We’ve had a carpet of phlox since we moved in a few years ago that isn’t coming up this year. I think the areas up top have been overgrown with grass I couldn’t keep up with last year. I put down new soil and I’m trying to use a selective weed killer but I’m having a really hard time pulling the grass up from inside the flowers. I’ve read you can just pull up the carpet of phlox but I’m having a hard time w that and idk if it’ll disrupt the part on the bottom bc that’s beautiful. Also every year it’s died when the weather gets hot then never reappears and it’s really ugly. Anything I can do about that?
2 - we had a beautiful carpet of those purple flowers (vinca?) and they aren’t growing either. I think bc there’s soil erosion I was able to pull all the weeds and I’ve put a few inches of new soil down but that’s not growing either.
Any suggestions are welcome!!
