Hello, I layed several thousand square feet of sod about seven weeks ago. We water it consistently but not too much. It’s rooted well. It gets full sun for the majority of the day with some shade in the early evening hours. The condition of the soil was poor although we did lay down some organics prior to putting down the sod. I’m cutting it once a week on the highest setting. I don’t bag the clippings. There is some slight yellowing and some thin spots have developed.
I’m curious if I should feed it now and if so with what? If not, what would you recommend going forward? Thank you very much.

You did not mention if you tested your soil. Results will give pH, liming, and nutrient deficiencies. Based on results it is a good idea to incorporate organic matter, fertilizer, and lime if needed before sodding or seeding.
If you did not add fertilizer when you prepared the soil or after laying the sod, it would be okay to fertilize at half rate now. If you fertilized at preparation, it would be okay to fertilize six weeks later. Look for a slow release nitrogen source.
Here is our fertilizer schedule on our website and information on fertilizing. The best time to fertilize is in the fall. Fertilize with no more than 2.7 lbs of nitrogen annually.
Because of the Chesapeake Bay and its tributaries, the state of Maryland has laws about fertilizer application: what, when and how much. It will depend on the condition of the lawn, the type of grass and be based on soil testing.
Test your soil first if you have not done so. If you have some thinning, you can sod or sow seed this fall.
