?how to plant grass kernel contained by hot temperature?
the best way in hot weather would be to grow plugs of grass first.
take some seedling trays, sew the grass seeds and water. dawdle until the grass is a couple of inches high. trim and water again. hang about a week and then transplant the plugs into the prepared lawn nouns. just spread the seed and sea it...it'll grow...daily watering for several days is required until it actually grows roots of their own. Spreading burlap or straw help to keep the moisture in too.
Yea, plugs and hay above are honest ideas. Do you have a cooler season, where on earth you can wait and plant it then. In most of the US, it's best to grow the grass contained by spring or fall.
If this is impossible -- hot year-round -- then you can do it yourself, but it will whip a LOT of personal attention and time.
For the first several weeks, maybe as long as 6 wks., you will have to river it several times a day -- like a minimum of 2 or 3 times a light of day. Just a light sprinkle, not a "big puddle lawn" soaking. Once the grass pops it's head out, next you can cut back to twice a day, consequently once a day. The it's time to cut the grass!
(So, you might want to do this when you are on vacation at home for a week or two, within the beginning, or have the "house caretaker" do it.)
A accurate trick is to soak your seeds before you plant them. Few folks know this. After you've soaked them, maybe overnight, then put them out on some weekly to dab dry and separate -- you can't just throw clumps of showery seed on the ground! And, always piece, rake, loosen the soil before you put the seed down and put a dilute layer of soil on top. ...and water. dutiful luck!
