How to determine your seed germination rate

Whether you are trying to determine if those seeds you have been stored for 3-4 years are still good or questioning your ability to harvest seeds on your own testing germination is a great way to take away from of the guesswork and avoid disappointment next spring.

The process is very simple, I believe I did the same thing in second grade during our plant section.  Though that was to observe how a seed sprouts/roots the concept is exactly the same.

Take a wet paper towel and place 10 seeds on it and place the wet paper towel in a Ziploc bag.  After a few days (or weeks depending on the normal germination rate) check back on your seeds and count how many sprouted.

In my case six out of ten of the jalapeno seeds sprouted.  So just do the simple math using the following formula:

Germination rate = (# seeds sprouted/# total seeds sprouted) X 100

So in my case:

(6 seeds sprouted/10 seeds total) X 100 = 60% germination rate

Of course the more seeds you use in your “trial” the more accurate the results will be for my purposes the error rate is good enough for me.

If I was a seed seller this would be disastrous since most distributors have germination limits (90-95%), but given these are for my own use and I have about 300 more seeds that I will use no major loss.  Though I will need to remember when I plant these out I will want to plant 2 seeds per cell to have good odds one of the seeds will germinate.

Another option is to give your 4 year old a handful of seeds and a pot full of dirt and see if most of them sprout.  Much less scientific but my daughter didn’t seem to notice.
