Best time to add seeds to the lawn is in fall; you could add some in spring, but if you don’t get at least 1” of rain - yes, you do need to water.
Don’t water everyday but 2-3 times per week- but very deep. Watering everyday leads to a very shallow root system: and you want your grass to grow deep roots to sustain itself
Do your best, but prepare for the fall.
Take pH test of your soil- do it properly, read instructions. It could be free or $5-10 from your local university.
You may need lime for your grass to grow well. In some acidic soils regions it may require so much lime, that one needs to lime spring and fall for 2-3 years to bring the pH to 6.5-6.8 - that how turf grasses like it - slightly acidic.
After you done liming - depending on the soil texture you may not need to lime for 20 years - depending on the soil buffering capacity.
If one in the west - the salts could be an issue you might need gypsum
Learn how to buy seeds: don’t buy contractors mix - full of junk sometimes even annual seeds - they won’t be there for you next year. Those germinate fastball- in 4-5 days, but won’t stay in your lawn.
Good turf grasses may take 21-28 days to come up or sometimes longer; be patient if you know you bought fresh premium seeds.
Read the label, make sure that germination test is very recent - ideally not older than 3-6 months ago.
Even fresh seeds may not germinate if stored incorrectly in heat, light ,moisture.
Educate yourself about how to grow turf grasses correctly - it is golden.
Meantime, while waiting fir the right season to thicken your lawn - just make sure to use a reel lawn mower, sharpen blades every 8 hours of mowing - sharp blades won’t tear up the grass - which leads to moisture loss, invites diseases and pests as the turf is stressed after each dull blade mowing.
Try to keep the grass as long as at least 3-4”, it would shade the soil- less light for weeds to sprout, have longer leaf blade to make food for its roots.
Don’t mow “on schedule” - you must not cut more than 1/3 of grass blade at mow time.
Most of the cool season grasses have 60% of growth in spring - so you might need to mow every 4-5 days or sometimes more - if it is very warm and rainy and if you fertilized - as the rapid lush growth occurs- which is btw - not good- lush growth invites pests and diseases.
The best time to fertilize - us fall - less pests and diseases pressure
However, you could take a break in the heat of the summer - when the soil becomes hot - the grass won’t grow - so you don’t need to mow - it is really bad to hurt the grass when it is trying to survive the heat (cool season grasses)
Cornell university, Penn state, UMass and others in your regions will have an extensive knowledge how to manage your lawn at home.
Don’t just read every silly things on the internet written by who knows who - a lot of wrong or insufficient, incorrect information out there - go to your local universities websites and read their facts sheets
