Perhaps someone else can help with the evergreens dilemma since I'm not aware of grass not growing because they were once there. If their former roots are near the surface, yes that will prevent grass from growing because it can impede root growth. However, it wouldn't prevent the seeds from germinating, plus you do have some plantlife there, after all. Lime amends the soil to bring the soil's pH into balance. The only way to really know if the soil needs lime is to have it tested. The test results will determine the need, how much to apply, and at what intervals to apply it. Whether your neighbor was correct in advising you to apply lime, I cannot be certain. But I imagine he is familiar with the soils in your area normally needing it. To help with your seeding problem, we will need more information. 1. Did you water the seeds often to keep them moist so they can germinate and grow? 2. Did you smother the seeds with lime? We will need a time factor or order of events to determine that since we don't know at what point you seeded and applied the lime. 3. Does the seeded area receive direct sunlight? Based on the information you've given us, I see no reason you won't be able to lay sod. With proper care, it should root and flourish. Where evergreens used to be, just make sure there are no roots left too near the soil surface.

1) Spray yard with "round-up" then after 10+ days & use rake to break surface of soil Apply seed at 6-10 pounds per 1000 square feet (check with local garden cewnter for low maintance varitey for your area) rake soil to cover seed lightly..... keep area watered (damp) 3-4 times a day till graas is up then once a day....mow after grass after reachs 3-4 inches (mow level to 2 inches)

Did you happen to plant a dwarf variety? They take forever to 'fill in' an area...very slow growers. And, yes, they do need loads of water. Does the area get much sun? Mine seem to spread faster in shade. 'Big Blue' Liriope is a fast grower and spreader but I don't know how hardy it is in your area...it also does better in shade but can take more sun than regular thin-bladed mondo grass. My big blue looks good all year.

Right about now is a good time to harvest. The berries should be plump and firm. Plant the seeds (the entire little "berry") immediately. You can do so just by poking the berries into the soil adjacent to the original clump to increase its size or in a greenhouse setting. This is not a fast plant to produce, hence its expensive nature - you'll need patience. Commercial propagation is typically by division of the spreading rhizomes Here is a link that might be useful: planting tips for black mondo seeds
