| What I am looking for is a general guide (like maple buds falling) that indicates air/ground conditions are getting to the right place. The website listed below shows working toward locating some of these guides. Maybe forsythia in full bloom (the one at the street corner nearby is in full bloom, but not the one at the end of my garden which is heavily mulched) is an indicator. |

| I'm not sure about a general guide other than 'days before or after average frost date' to plant. Below is a planting guide for our region from Southern Exposure Seed Exchange located in Mineral, VA. |

| The Southern Exchange website may have been down for a bit because I just clicked the link on my post and it worked. You can also get to the guide from the homepage of their website. The link is under the picture of their catalog and says "recommended planting dates on-line". |
