Reseeding a Damaged Lawn

I live in Charlotte, NC, and have the typical lawn damage sustained from the recent drought. Due to some health problems we were not able to overseed year before last as well, so my lawn is mostly crab grass. I have been putting down lime over the previous month and plugging the yard about every two weeks to improve conditions for growth. Would I be better off to "Round Up" the entire small yard before overseeding? Would it be a mistake to till up the yard and bring in a small load of topsoil or compost? Is it too early to do this or should I wait till the end of September?

With the problems you have had with weeds I suggest you use Roundup as quickly as possible to kill the weeds and existing grass. You can till the soil about 10 days after the spraying, rake out the dead weeds and grass and then re-seed the lawn. If you can find a good source of weed free compost you could add that at the time you till. In Piedmont North Carolina it is usually safe to reseed a fescue lawn until October 15.

Hurricane water damage to hibiscus

I live in an area that receive lots of hurricane Dolly rain -- my hibiscus was drenched before I could get to it to cover it. Drenched to the point that every single leaf wilted. I allowed it to dry out and am now watering gently with a growth enhancer. Branches are still supple, but wilted leaves are now brown and still hanging on. Should I trim them off or let the plant shed them on its own?? It appears that there is life, but only 2 new green leaf buds have appeared 2 weeks after the drowning. Is there anything else I should do? I live in hot San Antonio, Texas. ~

Be patient! I am not sure what you are using as a “growth enhancer” but most products should not be used every time you water a plant. The extra nitrogen in some products can cause even more root and leaf damage. If the plant is in the full sun you may want to move it to a place that gets good light but not hot afternoon sun. You are in effect going to treat the plant more like a newly rooted cutting until new foliage develops.
