A client just moved into a house, the previous owners had a rock garden with the plant Ajuga (ground cover)...I guess they switched it back to a lawn before they sold it to my current client. She has Ajuga all over her front lawn, and spots of it in the backyard and its starting to creep into the neighbor's lawn on her side yards. She wants her grass back! She refuses to have me use any type of herbicide as she has pets and she absolutely hates the stuff. I'm the poor guy trying to give her an estimate on this. Her lawn is about 6k sq. feet and the Ajuga problems cover about 1k sq. feet of her lawn. She wants an estimate for just taking out the Ajuga areas and an estimate for redoing her total lawn. I have experience with redoing lawns but not enough experience at estimating them. Is there a calculation hint for sq. footage for installing a new lawn with seed or do I just have to go through the steps of what I need to do and try to come up with a price like I do with everything else. Depending on which direction she wants to go, my plan was to rip out both the lawn and ajuga with either a sod cutter or skid loader. Then I was going to add cardboard to block out any sunlight on any Ajuga that I missed. I would then install new topsoil/compost on top of the cardboard, seed, and straw. I figured the cardboard would block the sunlight and retain moisture for the new grass seed for a bit before it decomposed. Has anyone else had experience going headon with an invasive plant? Does my plan seem sane? My only worry is that there may be more Ajuga lurking in her planting beds underneath all this other groundcover--Pachysandra, and may try to creep out again into the new lawn. I didn't see any but the randomness of where this stuff has popped up makes me worried. It even jumped a sidewalk somehow. This Ajuga may very well take over the world! Any tips or advice would be very much appreciated.
