If I put myself in the shoes of the customer:
- I'm not interested in 90% the blurb at the top. It doesn't offer me any value.
- The doctor/infant/parent story is a nice touch.
- The rest just gives facts. It doesn't actually tell me specifically what to do. How much do I water? When? How do I know when it's too wet/dry? Pictures? How do I know the temperature of the soil?
Perhaps you could have a simple checklist for each day or week
"Your grass was seeded on ______.
blah blah brief intro
Day 1 - Check X and do Y
Day 3 - Check A and do B
<insert instructions on how to do each thing you list above>"
