Not sure those seeds from last year are still good? Do a quick germination test to find out for sure.

If you are like most gardeners, you probably have tons of seeds from last year (and from years before!). Since different varieties have different “shelf lives”, you may want to do a quick germination test before you toss and reorder.

Wet a paper towel (moistened thoroughly but not sopping) and place 10 seeds on the top half. Fold the bottom over the top to cover the seeds and seal in a zip-lock baggy. Blow a little air into the bag so the seeds have a bit of oxygen, then put the bags in a dark place where you won’t forget to check them (I chose a kitchen cabinet).

Wait about a week (different varieties have different germination times — check the seed packet), peel off the top paper towel and count how many seeds have germinated. Fewer than 50% and you will probably want to re-order, 50% to 70% you would plant more thickly than usual, and over 70% and the seeds are as good as new!
