Very Special Tree People


It was difficult to bear the removal of our very large, old maple tree. I think this video was the only way I could make sense of it. (You’ll need to follow the link to view this.)

Autumn

The morns are meeker than they were,
The nuts are getting brown;
The berry’s cheek is plumper,
The rose is out of town.

The maple wears a gayer scarf,
The field a scarlet gown.
Lest I should be old-fashioned,
I’ll put a trinket on.

-Emily Dickinson

Harvest For the Future

samples selected for seed saving

Share



It seems wise – and maybe genetically prudent – that I should use the best samples from my harvest for saving seed. I try to find the most robust plant and its fruits for this task. The tomatoes that seem to resist cracking and disease and yet taste the best are selected. The least alien-shaped green peppers with the best taste are my “targets” for seed saving. Other qualifiers for my future harvests include:

• samples with the best color
• early fruits
• large fruits but not gigantic samples
• best taste trumps most other considerations

This is the first time in my gardening season that I think seriously about the next year. It’s just part of the cycle of the gardener’s life.

Anyone needing some information on saving seeds would do well to visit Seed Savers Exchange.

As a result of some friends on the Seed Savers Forum I am revising this post to add some information that I had forgotten and, in some cases, just didn’t know.

Dreyadin from the SSE Forum reminded me that it’s important to make an effort to keep the characteristics of a strain true to type. In other words, it would be counter productive to pick atypical samples such as those that may be very large, oddly-shaped, or extremely early or late. You more than likely originally picked seeds that produce fruits you like. There’s no reason to try to change them.

He further says, “Just keeping an eye out that you are selecting from healthy plants also is a factor.. in a situation where the plant may be effected one year, and if you have limited recourse.. there are a few methods to help try to decontaminate the seed.. but the result is usually a serious decrease in percentage of viable seeds left over.” Also, ” (It’s) always good to make sure you really clean equipment between batches just in case. Better safe than sorry.”

Finally, Dreyadin brings up a point that my photo seems to contradict. He says, “Just in the case of some peppers you use at the green stage.. you want those to fully ripen before collecting seed from them.” The photo does not completely represent vegetables selected for seed saving. My pole beans and green peppers are way too green for this purpose. Also, the two smaller yellow crook-neck squash are for eating while the larger almost-a-gourd one has mature seeds. I just thought the pole beans looked nicer in the photo than the brown ones I have been using for seed saving.

I use a fermentation process to rid my tomato seeds of pathogens. Dreyadin points to some more drastic means of doing this. He says, “The other methods to try to get rid of some of the more harsh pathogens are hot water treatment… bleach treatment.. and TSP (trisodium phosphate) treatment to name a few. They are all harsh.. the hot water one is the least toxic.. but regardless.. big loss in viability. Those are used in attempts to try to get rid of some of the diseases that get past the gel.. but Tobacco Mosiac Virus.. yer pretty much screwed as it gets right into the embryo.”

Again, thanks Dreyadin.

The revision also begs an additional photo…

Tomato Blight is Here!

Is this tomato blight?

Share


There is a disturbing article out of Rodale, the publishers of Organic Gardening, that tomato blight has been confirmed in several states. For tomato growers, both farmers and home gardeners, this is no small thing. This is the same disease that caused the mid-19th century Irish potato famine.

I suggest that you read Rodale’s article and do exactly what they say if you find symptoms of tomato blight in your own garden.

I am not sure that the photos taken in my garden this afternoon pictured here show evidence of tomato blight. I will research it further. In the mean time you might want to take a look at the Rodale article and then take a look at your tomato plants.

An Update Today…
I’ve come across a pretty good video for those wishing to identify late blight. This piece filmed last year for the University of Wisconsin – Madison is helpful in not only the description of late blight but also has information as to how to destroy the plants. Not all options given are organic but information for organic growers is offered. -Bill
