Growing Degree Days, Battleground WA

This information is from Western Regional Climate Center.

Trinity SE Sweetcorn need 1,190 heat units  Based on the info below, if I understand correctly, adding to May (now) 559 growing degree days, +1,190 = 1759 which occurs in August.  But I don't know that I understand this table correctly.

Pawpaws require 150 frost free days and 2200 growing degree days, which I am thinking we get here in Sept or Oct. Might be OK.

I bolded the line that seems the most relevant. 

Interpretation of the table:
"M = Monthly Data
S - Running sum of monthly data. 

Growing Degree Day units =  (Daily Ave. Temp. - Base Temp.) 

One unit is accumulated for each degree Fahrenheit the average temperature is above the base temperature. Negative numbers are discarded. 

Example: If the days high temperature was 95 and the low temperature was 51, the base 60 heating degree day units is ((95 + 51) / 2) - 60 = 13. This is done for each day of the month and summed.

Corn Growing Degree Day units have the limitations that the maximum daily temperatures greater than 86 F are set to 86 F and minimums less than 50 F are set to 50 F. "

Persimmon and Pawpaw Progress Report. 5.19.15

Flower Buds on Nikita's Gift Persimmon.  5.19.15

Last Remaining Flower on Sunflower Pawpaw.  5.19.15
All but one of the pawpaw flowers fell  off.  The one that remains is on Sunflower.  It takes a close look to see the developing ovary.  I don't know.  It might give a couple of pawpaws.  This one flower is the last chance for this year.

Saijo Persimmon had some flower buds but they fell off without opening.  Nikita's gift started growth much later, compared to Saijo, the growth is much thicker and stronger, and there are a few flower buds.  The tree is only about 3 feet tall.

Yates American Persimmon is also growing strong, and has some flower buds.  This is first leaf for that one.
Ember Plum on Hollywood Rootstock.  5.19.15
 The grafts are growing like crazy.  A couple of container apples on salvaged rootstock are not growing, but everything else is really growing.

Most of the bud grafts from last summer have about the same amount of growth as whip / tongue grafts from this late winter.
Hanska Plum, Top Grafted Onto Unknown Plum.  5.19.15

I've started removing some of the wrappings.  It doesn't seem to be girdling anything yet.  From the couple that I removed, doing so does not appear to have caused harm.
LaCrescent Plum Top-grafted Onto Unknown Plum.  5.19.15

Hollywood Plum Grafted Onto Toka.  Bud graft from 2014.  5.19.15

Fedco Apple Grafts.  5.19.15

Corn and Squash Seedlings. 5.19.15

The corn seedlings and many of the squashes were ready to be planted outside. 

I planted next to the fig row where I had covered with black plastic for 2 or 3 months.  The grass was dead, there were no significant remaining roots, and the soil was moist and easy to work.

I watered with diluted fish emulsion, and sprinkled some old blood meal / hot pepper powder around each to repel rabbits.  I don't know if that will work.   It's too much to fence each plant.

Effect of trimming tree seedling roots, ginkgo biloba. 5.19.15

The ginkgo seedling on the left, is the same age as the other two.  I was unable to dig it up with intact roots, last fall.  It had almost no roots.  I kept it potted, and did not prune the top.  The other two were smaller, and I was able to dig the roots intact.

The two with intact roots are growing fast, with elongating main stem and large leaves.  The one with almost no roots, survived, but growth is very limited.  The limitation of roots has resulted in limitation of leaf size and stem elongation.  It will be interesting to see if it catches up, this year or next year.

Bearded Irises. 5.19.15

Mixed Irises, mostly historic.

Bearded Irises were not a total loss this year.   I think the change that I need to make, is keep them mulched with a loose wood chip mulch.

Presprouting Beans. 5.17.15

Ning wants some Chinese beans. He has old packages of seeds.  I dont know the age.  Some packages are unopened.  They are made with a plastic-impregnated paper, and have bern in a cool place.

To give them the best chance I can, I am pre-sprouting them on moist paper towels, in zipper bags, on the seed sprouting warming mat.  I used seeds from 6 different packets.  I also did the same with some 1-year old corn seeds, to test before actually planting them.

Vegetable Seed Planting and Germination. 5.17.15

Image via vintageprintable.com
Sweet corn seeds are germinating.   Almost all of the containers have at least one sprout.  I still need to prep the garden bed for the sweet corn.

About half of the squash and pumpkin seeds have germinated.  I moved them from peat pots into slightly larger containers for root room.  Same as sweet corn, I need to prep the garden bed.

Today I planted melon seeds:

Petite Yellow  Watermelon 65-80 days

Blacktail Mountain  Watermelon 65-75 days

Minnesota Midget Cantaloupe - 60 - 75 days

Sakata Sweet Asian Melon - 85-95 days

Edens Gem Cantaloupe - 65-80 days

So far only one outdoor bush bean has germinated.

It's still early to on-time for all of the squashes, beans, and corn.  Corn was planted 5.12.15, beans 5.11.15, and squashes/pumpkins 5.11.15

More Seeds Planted. 5.12.15

Seed starting stand, sunroom.  5.12.15
This weekend and today I planted more seeds.  Now into the more warm-requiring types.

I'm not accustomed to planting squashes and corn indoors in containers.  That may be needed here due to cool spring season soil and temps.  Yesterday and today are cool and rainy.

I have planted most of the winter squash seeds, the summer squashes, green and yellow zucchinis.

Today I planted sweet corn, Trinity Hybrid, sold as a cool tolerant, early bearing variety that may work here.

LaCrosse Seed lists Trinity as "Trinity is a homozygous sugary enhancer bicolor with a clean compact plant, refined ear and good husk protection."  Purdue states, Sugar enhancer sweet corn "has a higher sugar content and is more tender than standard sweet corn" also "Isolation Requirements All sweet corn types should be isolated from field corn pollen by a distance of 250 ft. or by a tasseling date of 14 days. Supersweet (sh2 ) varieties must be isolated from standard (su) and sugar-enhanced (se) types by a distance of 250 ft. or by a tasseling date of 14 days. If not isolated, kernels of both varieties will be starchy instead of sweet.".  There is no nearby field corn.  I also have seed for Early Sunglow Hybrid which is an su type.  Continuing, "It is not essential to isolate sugar-enhanced (se) sweet corn from standard sweet corn: cross-pollination will not result in starchy kernels. However, isolation will permit the full expression of the sugar-enhanced traits. To maintain purity of color, white corn should be isolated from yellow or bi-color corn. Pollen from yellow or bi-color corn will cause some yellow kernels in white varieties. Pollen from yellow corn will lead to extra yellow kernels in bi-color varieties. Pollen from white corn will not affect yellow or bi-color varieties"  So I may decide to either plant the Early Sunglow 2 weeks later, or distant from the Trinity.  Complicated.

Mushroom box. 5.11.15

 Last week I bought a mushroom growing box at Home Depot.  Impulse.  Followed the directions.  Simple.

Today I noted the mushrooms are starting to grow.  The label states ready to harvest in 10 days.
