RT x GDZ F1 update

Well, disease is taking over the RT x GDZ #16 F1 despite my earlier pruning.   Not too surprising.  This may impede ability to assess fruit phenotype fully.  It's a bit confusing.  The first two fruit to form and grow are clearly ultra-fasciated as per the unique RT and GDZ phenotype.  In addition there was the megabloom from the last post; that fruit is not growing much.    However, there is another fruit that has an intact, flattened ribbed phenotype a la Costoluto Genovese.  And the newer flower to form seem modest-sized and have a modest number of petals, e.g. about 6.   So I am wondering if the first fruit were "megablooms", but the more typical fruit phenotype will actually be less fasciated than either parent.  That would be very interesting and suggest partial complementation, e.g. two separate loci.

Not ultra-fasciated, just ribbed and a little catfaced

Sick plant

Rest of patio tomatoes doing OK

RT x GDZ F1 fruiting despite disease

Looks like the RT x GDZ #16 F1 produces fruit that are clearly fasciated like either parent was, suggesting either that it is monogenic or was self-pollinated.    Here are an early stage fruit and a separate, impressive megabloom.

A new disease - bacterial canker?

My RT x GDZ F1 plant in 5 gal bucket seemed to have a unique disease/condition not seen in any of the other plants.    Browning of leaf margins ("marginal scorch"), mainly, on older leaves at the end of branches, and without profound wilting.  This is different than the wilt I've often seen in my garden bed tomatoes.  The leaf appearance matches images of what is most often called "bacterial canker" via online research. 

I isolated the pot from the other plants and around June 15 I trimmed off all of the affected branches, using an old scissors I was discarding anyway so as not to contaminate other plants.   Here are before and after photos.

Hay bales this year...meh

Not thrilled this year with progress in growing veggies in hay bales.   I have 2 bales and I think curing them went fine...   Tried direct seeding lettuce with mixed results; also direct seeding a few cucumbers seeds.  I noticed several sprouts disappeared overnight - something's eating 'em.  One row of lettuce is growing but one row lost all the sprouts. I transplanted my dill and cilantro starts into the bales but they didn't last long.   Transplanted my little pepper plants but something has been eating those too so they will probably not make it.  It's also been pretty hot and dry.   I put in a couple store-bought basil plants and they are surviving but need water every day.

Other 2018 crosses germinated mostly ok

As of 5/27/19 here are germination rates (after about 10 days):
For 2018 crosses #18, 30, 40, 45, 56 each: out of 12 seeds sowed, germ N = 5, 8, 11, 7, 1.
Neither of the 2 seeds from #26 germinated, which is not surprising.

Testing my 2018 crosses more thoroughly

Since two of my 2018 F1s had seemed to totally resist germinating, I decided to test all of my 2018 F1 seeds.   To recap, I already sowed 48, 22, 13, 16.  13 and 16 had multiple germinations with only 6 seeds sowed each.  After a failed attempt and repeat tests, 48 and 22 failed (total 18 seeds) and 57 failed (total 36 seeds).

Therefore ~5/16/19 I sowed 12 seeds each of the remainders - 56, 30, 18, 40, 45; There were only 2 seeds from #26 and the fruit was poor, so not expecting those to work but I sowed those too.  Incubating these outside since it's quite warm already.

As of 5/23/19 there are a few plants emerging, including one from #30, ZPT x GDZ.  Transferred to 4 inch pot.

Homemade low-ammonia, high-calcium fertilizer for tomato plants

This fertilizer is designed to have high calcium but minimal ammonia.  The plants need calcium to minimize end-rot, but ammonium ions have been reported to interfere with calcium uptake.


• 2 cups Hi-Yield Calcium Nitrate.   Can buy on Amazon.

• 1 cup 26-0-4 Vigoro lawn fertilizer; its nitrogen is mainly in the form of urea, not ammonium nitrate like many other fertilizers

• 1 cup Triple Super Phosphate 0-46-0, from Easy Peasy Plants.

• 10 cups wood ash.  I made this the old-fashioned way in my fire pit.  Wood ash has about 5% potash  (potassium) and about 1% phosphate, and as a bonus has a lot of calcium - up to 25% calcium carbonate. An alternative could be Espoma potash 0-0-60 6 lbs.   

This should make 14 cups.  I estimate this to have a makeup that is very close to 4-4-4 NPK, and is ~5% calcium.   Use 1/2 cup per 5 gal of planting medium.   

In practice, I carefully measure this "14 cups" but in the end I measured out 6 batches of 3 x 5 gal and it was gone, so I only got about 9 cups out of it !  I believe that when I thoroughly mixed the ingredients it compressed together, so I should have probably re-measured the whole batch and adjusted accordingly.  This means that I may have overshot the fertlizing by about 50% or so.
