Saving Tomato Seeds

October 4th, 2010

I’ve been saving tomato seeds for a few of my favorite varieties including: ‘Principe Borghese’, ‘White Beauty’, ‘Brandywine’ and ‘Goldman’s Italian American’ tomatoes. Saving tomato seeds is an easy process, if you have a favorite heirloom variety you should give it a try to preserve it.

The most important part is choosing a few of your best tomatoes. Obviously these tomatoes have had great germination and have good genes to pass on. Ideally you’d want to choose a few nice ones from different plants (of the same variety of course), but don’t worry if you only planted one plant, the seeds will still be OK. I only have on ‘Brandywine’ plant and I save seed from it every year.

All you need to do to save tomato seeds is to scoop out the seeds and gel and put them into a jar. Add some water and let them sit until a scum/mold forms on the top of the jar. This process ferments the seeds and helps remove them from the gel, I’m guessing it also helps kill bacteria and disease. All the seeds will sink to the bottom when they’re ready to rinse. Generally I let mine sit for a week or two.

You’ll want to skim off the scum/mold, then pour the contents of the jar into a colander and rinse them to get rid of all the gel and any scum. Next you’ll want to spread the seeds on a towel to dry (I prefer a cloth towel as I find the seeds don’t stick as much as they do on a paper towel). When they’re good and dry, put them in a small envelope and label, they’ll be ready to sprout next spring. Make sure you keep them labeled throughout the process as you don’t want to mix them up! Label the jar, label the towel you’re drying them on, and label the envelope, believe me you won’t remember – I know from experience!

Not only is saving your own seeds a great way to keep you favorite tomatoes around, but it’s also a great way to save some money on seeds and have some from trading with friends. You can also give them away to encourage others to garden and grow some of their own food. I’ll be giving away some of mine in a few weeks when I have them all saved.

Do you save your own tomato seeds?
