How to Save Tomato Seeds

This year we had a need to save tomato seed for the first time because we were running out of our beloved Blondkopfchen yellow cherry tomatoes from Seed Savers Exchange, and we also wanted to save seed from a wayward tomato plant that found its way to our garden this year via the community compost. Of course we intended to save seed at some point which is part of the reason we buy open pollinated and heirloom sees. It was a cool process and I wanted to share our experience. The interview with the SSE president about the importance of seed saving in this quarter's Urban Farm magazine reminded me that I still needed to write a post about so here it is.

Instructions:
The instructions we followed were from the 2012 Baker Creek catalog which had a great photo excerpt of Jere Gettle's The Heirloom Life Gardener showing the steps for saving seed (in pic below). We supplemented these instructions with some from the International Seed Saving Institute.The steps below in bold are from that site interspersed with photos and comments (in italics) about our experience.

What did we want to save?
We were trying to preserve seed from our Blondkopfchen and also from our amazing "volunteer" red cherry/roma mix that appeared in our garden this year uninvited but which was beyond prolific. 


Process: Cut the tomato into halves at its equator, opening the vertical cavities that contain the seeds. Gently squeeze out from the cavities the jelly-like substance that contains the seeds.



Place the jelly and seeds into a small jar or glass. (Add a little water if you are processing only one or two small tomatoes.) Loosely cover the container and place in a warm location, 60-75° F. for about three days. Stir once a day. We forgot to stir. Whoops.
 

A layer of fungus will begin to appear on the top of the mixture after a couple of days. This fungus not only eats the gelatinous coat that surrounds each seed and prevents germination, it also produces antibiotics that help to control seed-borne diseases like bacterial spot, canker and speck. What they didn't say was that this fungus smells really bad (kind of like moldy cheese). The red tomato had bigger pieces so it developed a fungal layer much more quickly than the smaller yellow ones.




Here they are after 4 or 5 days. We couldn't get to them right away so they may have sat longer than they should have. Again, whoops. 

 
After three days fill the seed container with warm water.


 Let the contents settle and begin pouring out the water along with pieces of tomato pulp and immature seeds floating on top. Note: Viable seeds are heavier and settle to the bottom of the jar. I thought the instructions were wrong because if I poured out the contents I thought the seeds would also slip out. So instead I tried to spoon off the mold. Ugh. It was gross and didn't work. I finally did as the instructions advise and just poured and lo and behold the icky stuff poured right out with no fuss.

 Repeat this process until water being poured out is almost clear and clean seeds line the bottom of the container. Pour these clean seeds into a strainer that has holes smaller than the seeds. Let the excess water drip out and invert the strainer onto paper towel or piece of newspaper.  We didn't have a strainer fine enough so I just poured out as much water as I could and then poured the rest through a paper towel. This worked just fine.




Allow the seeds to dry completely (usually a day or two).
 



Break up the clumps into individual seeds, label and store in a packet or plastic bag. I didn't realize the seeds would have a little furry coating. I took out some packet tomato seeds to compare and sure enough, they also have a furry coating. This produced a remarkable amount of seeds. We will have enough for years to come, but if we have a particularly good year with these next year I may do this process all over again to keep breeding stronger performers. 




Reflections on Seed Saving:

I can't yet comment on the vitality of the seed (will follow up this summer) but the process definitely made me feel like I am contributing to the ongoing story of our planet's food legacy, particularly by saving seeds from the volunteer tomato. To be an heirloom an OP seed needs to be between 30-50 years old by most definitions but usually getting to heirloom status means that a plant worked particularly well in one part of the country for a long time. This tomato plant appeared in our garden unexpectedly but was so successful we wanted to save it to try again. In Michael Pollan's Botany of Desire terms, this plant "used" us to help it procreate by offering us something we wanted: an abundance of tasty fruit. If we are still using it in 30 years Seed Savers Exchange may even want some of them :)

Rosalind Creasy's, the author of Cooking from the Garden and quoted in the Jan/Feb 2013 issue of Urban Farm, description of what would go on SSE packets if there were space sums up my feeling nicely: "By planting the seeds in this packet, you have become a steward of our food heritage, a link in a chain that goes back thousands of years. Use his seed to grow food, but please save the seeds, share them with others and replant them again in your garden to allow the seed to adapt to your local growing conditions."

Patching the Row Cover


This weekend we realized that the edges of our row cover where we drive in the garden stakes to secure it to the ground had made large holes around the stake entry points. This is caused by a combo of normal wear and tear and the number of wind storms we had this year. My clever hubby found a great way to patch it though. Just like all other row cover care, he used good ol' duct tape. He placed a piece over the stake holes and then drove the stake through. Now the stake still has something to grip and the cover is very secure.

Single Stemming Tomatoes: Does it work?

 Since out tomato plants are winding down I thought I would do a review of  the new approach we tried with them this year. Instead of cages, we grew them on a trellis and we "single-stemmed" them.

What the heck is single-stemming?

Single-Stemming requires you to pinch off the suckers (those extra tomato stems that grow in the notch between the stem and branch of the plant) so that the tomato grows mainly on one stem with only main branches. This allows the plant to focus on setting fruit instead of growing more greenery. When the tomato reaches the top of the trellis you top it off so that the plant focuses the rest of its energy on the remaining fruit below.

We have tried to do this in previous years but it is much more difficult to get to all of the plant when it is caged and after a week or two we usually forget. Then overnight the plant sprawls everywhere and we give up. Not this year. After we saw the youtube video below we were convinced that if we did this religiously it would yield us more tomatoes.





Even though we don't square foot garden (after our very bad experience year 1 of community gardening), this convinced us that in addition to the single-stemming we should also try trellising again. We made really inexpensive trellises year 1 from conduit we bent to shape at Home Depot. But unlike years past, we bought trellis netting this year instead of using single strands of jute, nylon cord, and other trellis materials we have used before (which have all buckled under the weight of the plant before the end of the season).


How did it all work out?

Following this method we were able to fit many more tomatoes in our tomato bed. The trellis netting held the plants up exceptionally well as long as we stayed on top of weaving the new branches through the squares in the net. The single stemming kept the plant looking lean and orderly and still allowed it to set tons of flowers that turned into many, many tomatoes. 
 



Also, we had better air flow that I believe prevented the spread of disease. Our garden neighbor usually crams 20 tomato plants in his 4x8 beds and invariably they are disease ridden by early June. This doesn't bother him because he has so many plants that enough survive to meet his needs, but to us, with our handful of plants, this is very worrisome. This year it was particularly bad, and I feared that it would quickly spread to my heirlooms (which have no specially bred disease resistance) that were only a few feet away.

But lo and behold, it is the end of the summer and whatever was affecting our neighbor's didn't bother ours. We did eventually end up with a little blight but even that took a long time to spread to all our plants, and I believe the air flow made the difference.



The final verdict:

Single-stemming plus deep watering (post coming soon) is the way to go. This is definitely how we plant to grow all our tomatoes in future seasons.  The results make it worth the extra work.

I Heart My Row Cover

As discussed in earlier posts, this year we finally put up the hoops to use our floating row cover which was purchased last season from garden's alive but didn't get used. At first we were a bit skeptical that it would really work but after 2 years of losing our bean crop to the mexican bean beetle we were willing to try.

If you are not familiar, the mexican bean beetle is an insidious little creature that is immune to all but the most hardcore pesticides, which of course we do not want to use on our organic garden. We used kaolin clay last year (under the brand Surround At-Home Protectant) which worked okay but you have to apply it regularly and it is really hard to spray the underside of every bean leaf. So this year, our plan was just to keep them off from the start.

Boy, has it worked so far!! Everything else in our garden has been ravaged by the pests that got a free pass this year with our un-winter but everything under the row cover looks amazing. If you follow us you may remember that we were having problems with pill bugs in this bed earlier in the season. Our hypothesis worked...we worked in more organic material for them to eat and they have left our plants alone ever since.

We plan to use more covers in the future, particularly for the self-pollinating plants like the peppers and the eggplant. Luckily we do have a second cover to use; we just have to put up more hoops first. Seems like garden construction is never finished.


Here is a pic of our row cover all buttoned up. We use garden stakes around the edges and pots at the ends.




Here are what our beans and beets looked like when we peaked underneath a few weeks ago:



Here are our beans about a week ago: (They have NEVER gotten this big before without most the leaves suffering from various degrees of skeletonization). Supposedly they self-pollinate but we are starting to get nervous about that and may roll the cover back for a bit to let the bees in.

 Some of our harvests so far...yummy cynlindra beets. When you cut into them they are the most gorgeous blood red color.



 And here are some gorgeous golden beets waiting to be harvested.


We have only had one sacrifice so far. Something stripped the one and only kohlrabi that germinated in this bed. We suspect slugs. But whatever it was it has left everything else along. Thank goodness for small garden miracles.
