Testing Old Seeds

If you have seeds leftover from previous years, rather than throwing them away, test them out now and save yourself some money.

I like to test them out by using conditions similar to what I normally use. I put in three seeds in each cell and mark each with the name of the seed and the date. I cover the seeds with a plastic lid to keep things moist and also use a shop light to keep things warm inside.

If the seeds germinate, then you know you can use them this year.

I used some vermiculite I had, but you can use any good potting mix. I don’t plan on keeping these plants – they are just letting me know the germination rate.

Note – I am also testing some new seeds from dollarseed.com
