Seed Starting 101 - Easy Steps to Seed Germination
Timing your seed startsIf you already have your seeds in hand, check your seed packet for germination times and read the instructions on when the plant should be transplanted. For example, squash is sensitive to getting rootbound so it should be started 3-4 weeks before the last frost in a larger container. Tomatoes and peppers need longer times and are typically started 6-8 weeks before the last frost. If you're doing cool weather veggies, some of them, like broccoli and cauliflower, should be set out BEFORE the last frost. Still making up your mind? Here's a chart from Penn State Extension with helpful information on how and when to plant a variety of common veggies. The date of the last frost in your area is crucial. Planting your seedlings outdoors before the last frost typically leads to heartbreak when the seedlings are zapped by a cold snap. So please, don't try to jump the gun on that outdoor planting date. Count back from the last frost date to calculate when to start your seeds. Or we have made it really easy if you use our Seed Planting Calculator.

I've seen ten-year-old Speedling trays still in service and looking great. Standard plastic trays are easy to work with and very durable.
The bio-degradable route is a great option for sustainability: To minimize transplant shock, try Soil Blockers This innovative method doesn't use a container at all, just a compressed block of media. Roots are air-pruned and the block is dropped right in the ground. For more info on this method check out our video. CowPots that are made from manure and can go straight into your garden soil. Their cousins coco peat pellets, and coco fiber pots are some other marvelous options. Fill your containers with a soilless mix, like our organic QuickRoot, place your seeds two to a cell (Tricia likes to use the Widger as a seed spoon), and water well with a fine spray. Our classic Haws watering can has a removable "rose" on the spout that will sprinkle your seeds and seedlings with droplets. Make sure your seeds and seedlings get a continuous supply of water.
