- Margaret Roach and Johnny’s offer seed-starting calculators. Enter your frost date, and it calculates when seeds should be started indoors, transplanted, or directly sown outdoors. NOTE: Use these calculators as a rough guide. In the spring, I use two sets of frost dates: a riskier one for cold weather crops that can handle a bit of frost and a more conservative one for warm weather crops. Tomatoes, for example, not only can’t handle a frost, but they’re also generally not happy at temperatures under 60 degrees F.

- How long will the seed last? You don’t have to toss out all of your old, unused seed, but some varieties have a longer shelf life. Check out Margaret Roach’s guide.
- URI’s free seed program has been limited by COVID-19, but it may be an option for non profit groups in future years. Wintersown.org also offers seed at under-cost rates to community organizations.
Winter Sowing & Season Extenders
- Winter sowing is a method of sowing seeds outdoors when it’s still cold in containers such as milk jugs. Susan Mulvihill has a nice video on the technique and also points interested growers to wintersown.org.
- You can get more grow time out of your garden by using season extenders such as hoop tunnels, frost covers, and cloches. Eliot Coleman has researched and written on this topic extensively, but for home gardeners, I found Niki Jabour’s materials more accessible. Here’s her website, a book that’s available on Hoopla and hard copy at Thayer Public Library, and her latest publication about growing under cover.
- From GrowVeg, check out this simple method of using milk jugs as improvised cloches. Great idea if you have a late frost sneak up on you.
