We've added a couple of new tools to help growers plan when to start seeds inside and when it's safe to set seedlings outside for transplanting.
To check out these tools, visit the Johnny's Selected Seeds home page. At the top right, you'll find links to download a seed-starting date calculator, and a soil temperature chart. You'll need a copy of Excel, or similar spreadsheet software to open and use the calculator. You can also import the calculator into Google Documents.
The information was provided to us by Lynn Byczynski, editor and publisher of the "Growing for Market" newsletter and author of several books, which are available in Johnny's online bookstore:
The Flower Farmer: An Organic Grower's Guide to Raising and Selling Cut Flowers; The Hoophouse Handbook; Market Farming Success.
We've also added a soil temperature/germination chart.
