I would like to know when and how to get our lawn ready for winter in Vancouver WA. What is the best seed for overseeding and what is the best fertilizer for winter? I asked this question on 9-01-07 but never got a reply. Thank you for your prompt reply to my query.

I remember answering your question earlier this month. Perhaps your return email address was incorrect? Whatever the reason, here's the reply:

A fall application of fertilizer will help the roots remain healthy throughout the winter months. WSU recommends a fertilizer high in phosphorous and low in nitrogen, applied in late November or early December. Tall fescues or Kentucky Bluegrass are most commonly grown in your area. Your lawn will need about one-inch of water per week from now until late November. Natural rainfall should take over until next spring. To keep your lawn healthy and happy, put it on a regular feeding, mowing and watering schedule next spring. Use a 3-1-2 ratio of NPK and apply in April, June, September and late November or early December. Home Depot generally has just the right fertilizer formulation on sale at just the right time for application in your region. Best wishes with your lawn!
