Filled up the pool with dirt, now trying to figure out HOW and WHEN to plant seed. Also, I have a few low spots from digging out stumps last fall, what should I use to fill these before planting? Fill or top soil? Do I need to cover everything with top soil, or is this not necessary? I'm thinking I'll buy mostly fescue seed as a good chunk of my yard is in the shade once the tree's fill in, but any suggestions appreciated. Also, where is the best place to buy good topsoil from? I still have some sand in the area I need to plant, and I'm a bit worried that it wont hold enough water for the seed to germinate.
