To be clear: please repeat what you did to the ground in front of your residence last fall, kjeliaz.

@rifis Last fall the old grass was removed by cutting it very short than power raked . The soil was tilled and covered with a few inches of new soil and compost. Then seeded and starter fertilizer applied. That was in second half of September.

kbg?

Nice job. I see you have done this before. It has been the best spring in 20+ years for lawns and all things flowering.

Does not appear to be melting out.

Iron chlorosis?

@rifis Thanks for the clue. I will have to check for nitrogen deficiency also as I noticed irregular growth. Time for a soil test tomorrow.

This is tall fescue mix.
