Hydroseed now? Or wait until fall?
Im in southern new hampshire. My builder is on the final stages of spreading loam on my property, there is about 77,000 sq ft total.
They are recommending to hydroseed immediately but my concern is that its to hot mid summer.
The final payment with the bank includes the loam and seed so I understand why they want to get it done sooner then later.
My well only produces a little over 5 gallons a minute and I was told that it wouldn't be enough to water my property long term because of how large it is.
My builder is saying it will be fine as long as I water 3 times a week and fertilize, but I'm concerned he just wants the final payment. He aslo told me that if I wait untill fall that I will have to pay them to remove all the weeds and harley rake it again.
Im worried that I won't be able to to keep up with the watering and that the new grass will be scorched.
He said the decision is up to me, but as soon as they hydroseed I'm responsible for what ever comes next.
Any advice or recommendations would be greatly appreciated.
What do you all think?
EDIT: Thank you for all the responses. Right now the soil is pretty well compacted as it was moved with a bulldozer. I asked my builder if we could hold off until fall and he responded by saying he estimates it would be another 5-10k to remove all the weeds in the fall and to rework and touch up the loam then. It sounds ridiculous to me, but is there any truth to it?
