When to seed lawn, or re-sod - Knowledgebase Question

When do I replace the grass in our lawn? We originally had St. Augustine,(Palmeto,or Floritam; not too sure which). It suffered intense mold and mildew. We treated, then in the Fall, we overseeded to fill in the dead, and bare spots. Now the Winter rye grass,which is still green, needs to be replaced. What is the procedure? Uproot the rye, fertilize over it? Seed or sod?
Thank you,

The ryegrass will go dormant when the weather gets hot and your St. Augustine (or whatever warm season grass you are growing) will green up. The beauty of having both warm and cool season grasses is that your lawn will be green most months of the year. You can seed over sod but there are no seeds available for St. Augustine. There are seeds available for bermuda and centipede grasses, though, and these are both warm season grasses. I'd just mow the existing grass and ferilize it. The ryegrass will die down in the next 3-4 weeks. Hope this sheds some light on the subject.
