A cold frame in a transparent structure that traps heat during cold days and protects plants from the cold at night. It can be something a simple as a pair of storm windows, lying against each other on their sides, with improvised end caps.
It’s important that you realize how quickly a cold frame can heat up on sunny days, so adequate ventilation is important. It’s also important to build the cold frame sturdy enough to withstand high winds.

What Are Cold Frames?
Wednesday, April 29th, 2009Guide to Avant Gardening: Part 3 ~ The Expectations
Monday, April 27th, 2009As a gardener you should expect great things. And you should expect some setbacks. Any seasoned gardener will tell you that not a season goes by without successes and setbacks. Celebrate your victories. Don’t take your failures personally.
And despite what some books may promise, gardening is hard work, especially in the beginning. But as your knowledge grows, so will your harvests. Have faith. Work hard.
Guide to Avant Gardening: Part 1
Friday, April 24th, 2009When thinking about plants, it’s important to remember that life on our planet wouldn’t exist without them. By taking seemingly intangible elements from the air, ground and water, and combining them with sunlight-plants perform everyday miracles upon which our survival depends.
Think about it, plants germinate, grow, reproduce and respond to their environment in the same basic ways we do. But they do it without a brain or central nervous system, without muscles or a skeletal system, without any apparent premeditation. Which, as one British horticulturist noted, should give some of our more smug vegetarian friends pause. Plants utilize the fourth dimension– time-in ways unknown to us.
Plants are a 200 million year-old experiment that continues to this day. As Michael Pollan pointed out in his excellent book The Botany of Desire, plants are using us to their ends at least as much as we use them to ours.
Guide to Avant Gardening: Part 2
Friday, April 24th, 2009To read the first part of this post, click here.
Only once people realized, some 4,000 years ago, that they could harvest seeds and plant them, did civilization begin. Hunter-gatherers became agriculturalists, camps became cities, and social, military and economic strata arose. Early farmers were selecting for plants and animals that were bigger, tastier, stronger and faster growing. In the Middle East wheat proved to be the grain of choice. Halfway across the world in ancient Mexico corn began development. And in the Far East rice cultivation arose. Crops were selected for specific qualities suited to a specific area. These crops-known to some as “landraces”-fostered a genetic diversity.
With the advent of modern agriculture, this diversity shrank to the vanishing point. The Green Revolution of the 1950’s stressed, among other dubious ideas, genetic conformity and monocultural farming practices.
This in turn meant that many of the staples of our existence-wheat, corn, rice potatoes, bananas-had very little genetic depth and a very high chance of failure should a pest or disease get a foothold.
At the same time Robert Rodale was starting a revolution of his own in Pennsylvania. He was the father of modern organic gardening, which stressed building the soil and discarding the many poisonous chemicals associated with modern farming.
His methods stressed sustainability and the incorporation of natural methods of fighting off pests and diseases.
Since the first publishing of his book in 1947, organic gardening has become gospel among health-conscious gardeners, for good and occasionally ill.

Timeline for Wedding Invitations and Stationery
Thursday, April 23rd, 2009
Engagement announcements - Soon after engagement is announced.- Solidify the guest list to the wedding prior to making any stationery decisions. Make sure you order at least ten extra invitations for any last minute additions to the guest list.
- Save the Date - At least three months prior to wedding. These are especially important if there are a lot of out-of-town guests or if the wedding is planned during the holiday season or summer.
- Invitations - Sent four to six weeks prior to wedding. So plan on ordering about two to three months prior to the date of the wedding.
- Announcements - These are sent out to announce that a wedding has taken place so they should be sent after the wedding and within a year of the wedding date.
- Thank you notes - Should be sent as soon after the wedding as possible to let the sender know not only that the gift was appreciated, but that it was received.
