Re: Lawn seeding
IMHO, it's better to seed when the grass will germinate and have a chance to establish and sustain itself over a winter. I can tell you that here in California I've had the best luck with early to mid spring when the trees start to bud out. At this point the ground is warming, but the seasonal temps are not such as to harm new sprouts. It takes less water in cooler climates, and is easier for the grass to establish before summer temps take effect. When I've planted in the fall, the seed tends to rot in the ground, if not eaten by squirrels and birds who are trying to winter over on the available tasties they can find.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
