Saijo Persimmons. 11.9.16

Saijo Persimmons, with Nikita's Gift for Comparison.  11.9.16

Saijo Persimmon.  11.9.16

I placed Saijo Persimmons into a plastic box with apples for ripening, for a few days.  They are now very soft and sweet with no atringency at all.  Nice flavor.  I think I like the Nikita's Gift better, but if I had not tried those, I would like the Saijo a lot.

Only 8 persimmons on the Saijo tree, but that's OK.  This is my first taste of this variety and this is the first year of any persimmons in my orchard.  Very nice.

Nikita's Gift Persimmons. 11.4.16

Nikita's Gift Persimmons.  11.4.16

About 10 days ago, maybe less, I cut these persimmons from the tree.  They were firm and fully colored, although not as red as now.  I placed them in a plastic bag with 3 apples for ripening.  Now they are as soft as a slightly overripe tomato. 

I sliced in half and scooped out the jelly-like contents with a spoon, eating like a small cup of pudding.  Excellent sweet flavor, with a spicy element similar to clove or cinnamon. 

So now I know, at least these persimmons can be grown and ripen in my cool summer, short season Southwest Washington State climate.  So good.

There are some Saijo to follow.   A little behind Nikita's Gift, but not by much.

Fall Chores, Persimmons, Zucchinis, Garlic. 10.29.16

Vegetable bed covered with leaves.  10.29.16

 Yesterday I raked up a neighbor's maple leaves.  Those now cover a bed that was Indian Corn (this year) and will be kitchen garden (not sure - potatoes, onions, tomatoes, squash) next year.  I chopped the corn stalks into about 1 foot sections, and also spread lime before spreading leaves.  It should pack down and mostly decompose to dig in, by late winter.

The Last Zucchini.  10.29.16

Nikita's Gift (Plate) and Saijo (Countertop) Persimmons.  10.29.16

 I also went around the neighborhood to ask neighbors for their leaves.  That way, they get some old guy to rake them up (me) quietly with rake, not a blower, and haul away.  I get a big pile of tree leaves for the vegetable beds.

Baja (Roja?) Garlic.  10.29.16

More Garlic Starts.  10.26.16

One last zucchini.  Such a good year for those.

Picked about 1/4 of the Nikita's Gift Persimmons.  They are hard, so will need to ripen.  I placed them into a bag of apples to assist that process.

Apples produce ethylene gas, as part of their ripening process.  The ethylene gas will help the persimmons to ripen, too.

Not sure about that Saijo, there is still some green.  The rest, only about 6 fruits, are still on the tree.

The garlic starts from local nursery, they labeled "Baja" but I wonder if they are Spanish Roja, are all growing nicely.  When I get a chance and it's not raining, they need hoeing for the weeds.  I checked other local nurseries, no garlic starts.  Finally, I checked Portland Nursery, they had multiple types.  I bought 2 heads of "Duganski", just for variety.  Ordered from a catalog, I would have to order more than I need, for an even higher price plus shipping.  Territorial sells Duganski.  "beautiful, purple stripe garlic with large bulbs and an amazing flavor that matches its looks and size. Purple outer wrappers protect the violet-tinged cloves that burst with a fiery flavor and mellow out with a pleasant aftertaste." This is just for novelty, see if they are different from the Inchelium Red that I grow each year.

Speaking of Inchelium Red, it's far behind the Baja/Roja this year.  A few have germinated, maybe 10 of the 40 or so that I planted.

Edit 10.30.16  It turns our there actually is a Baja Garlic, called "Baja Morado".   From the link - "Baja Morado...  was at first thought to be a long storing Creole but upon detailed examination turned out to be an even longer storing Silverskin that has a nice pleasant garlickiness with some pungency... similar to Mexican Red Silver but with much white in the clove covers rather than solid deep red."  As with anything from nurseries, local and mail order, it's best to take things with a grain of salt.  But who know"  Maybe this IS Baja, and Baja Morado at that.

Fertilizing Trees in the Fall. 10.18.16

This post is a lot more dry than usual.  I have wondered whether it is beneficial to fertilize trees in the fall.  For the past few years I have done so, and do not see harm occuring from that practice.  In addition, the fertilized trees do seem to have a good burst of growth in the Spring, more than trees that I have not fall-fertilized. 

Different websites give different advice about fall-fertilizing of trees.  For the most part, these sites refer to deciduous shade trees.  Much of the research that has been done, relates to conifer forestry.

Growingagreenworld.com:  "many experts now consider late fall, or about a month after the first killing frost, to be the ideal time for applying fertilizers. We now know plants utilize nutrients throughout the year in different ways."  The site further states, that when trees are dormant, their roots absorb nutrients and apply them to root growth, disease resistance, and storage of nutrients for Spring.  I don't know if those claims are supported by science, but they make sense.

According to the University of Minnesota extension, early Spring is the best time.

Gregory Forrest Lester (Ohio) states that Fall fertilization is essential.  Again, the rationale is to prepare for Spring.  There aren't a lot of sources regarding fall fertilization of trees.  Via google scholar, there has been some specific research, that may or may not apply to yard shade trees.

Annals of Forest Science.  Related to seedlings of red pine,  "Results suggest that fall fertilization of red pine seedlings can help render desired target height in the nursery, while maintaining or increasing cold hardiness levels."  Benefits were seen for number of needles. concentration of nitrogen in shoots and roots, and cold hardiness parameters.

Western Journal of Applied Forestry.   Related to Douglas fir seedlings, fall fertilization increased nitrogen concentrations in the seedlings.  There was no difference in root growth or cold hardiness.  It did not appear in this project that fall fertilization had much effect.

Annals of Forest Science.   Regarding a species of oak,  "early fall fertilization promotes nutrient loading of P(hosphate) in Holm oak, with significant effects on root growth potential and field growth by means of a phenologically earlier development and a higher aboveground biomass."  and in the discussion it was noted that "six months after planting, fall fertilized plants showed higher shoot biomass, higher proportion of new leaves, and faster development, producing leaves earlier compared with unfertilized plants."

 Southern Journal of Applied Forestry.  Regarding fall fertilization of one year old longleaf pine, there was "substantial overwinter dry weight gains and increases in nutrient content and concentrations" especially for nitrogen.  Based on their research, they conclude that fall fertilization "offers a means of increasing seedling size and nutrient reserves prior to out-planting on the relatively infertile sites where seedlings are normally established."

 Journal of American Society for Horticultural Science.  Regarding field-grown peach trees, there was not a benefit for fall fertilization vs. spring fertilization, for peach production or tree growth.

Journal of Agriculture.   Regarding shade tree fertilization researchm up to 2002.  The authors state that nitrogen usually appears to be the most important nutrient, and note that "studies conducted with (labeled) nitrogen

showed low N(itrogen) uptake during the dormant (leafless) season, bringing into question the practice of dormant-season N applications."  However, they also note the inadequacies and limitations of the research that had been done.


Canadian Journal of Forest Research.   Regarding more Douglas fir seedling research, one month after fall fertilization,  "Total nitrogen concentrations increased 1 month after fertilization, remained stable throughout winter, and tended to decrease or remain stable just before budbreak."

My conclusions:  A lot more work is needed to determine whether fall feeding benefits, doesn't benefit, or harms trees, and in what situations.   There does appear be benefit in some situations.  Nitrogen sources are more likely to be beneficial, and unless a deficiency is seen, fertilizers that contain signicant amounts of other major nutrients are usually probably not useful.  If one is interested in pee-cycling,  that seems like a reasonable approach as long as it is not overdone.  A liter of "liquid gold", diluted to 4 liters, could be applied over an area of about 10 feet by 10 feet, to a tree with a drip line about 8 feet in diameter.  It's not rocket science, and I would not do so if the soil salts are high.

Update. Ginkgo #2. 10.17.16

Ginkgo Tree Planted Summer, 2012.  Now 10.18.16

Above Ginkgo Tree after planting in 2012.

It's obvious by now that I have a Ginkgo biloba tree obsession. 

This was the smallest of the trees that I grew from seeds that my late father collected qround 1995 in Illinois.  I kept it in a flower pot, then planted in poor soil at the place in Vancouver, then when we bought the Battleground place, moved the tree there. That was 2012.  It's done nicely, and was given minimal water this summer.  It's turning into a handsome tree that my Dad would have been proud of.  I miss him.

The parent tree was grown by a neighbor in that small Illinois town.  That neighbor was a WWI veteran, a German man who was in a British POW camp for part of the war.  He later emigrated to Illinois.  I remember his telling me that Gingko biloba trees had a shape like pine trees, and were around in the time of dinosaurs.  He grew his tree from a seed as well.  That tree was the source of the seeds that my dad collected.  It has since been cut down.
