Cucumber plants are several inches high but on of them the stem shrunk
and withered from ground level up to about an inch. This has killed the
plant. What is that and will I need to worry about the other plants?
They all look healthy to my untrained eyes.

The key that I'm looking at says,

"Plant wilts slowly but permanently, with no
recovery at night; stem may rot at the base" .......fusarium wilt

IIRC you are screwed (sorry).

Thanks. This seems likely as the soil here is from leaf litter and it
would not surprise me if it had fungi. The deceased plants roots looked
fine, as that article had mentioned. For that matter, so did the rest of
the plant, until it fell over.

I'll keep watching. Any chance cat urine could do it in? I'm herding
cats faster than I can spay them.

If it wasn't there before, it probably came in with the seed. Salts from
cat urine would just have made it wilt and cats aren't likely to carry
plant diseases. I have the same problem with basil in one spot in my
garden. Look for fusarium resistant plants to put in that area.

OK, I'll do exactly that. I see I have a Downey Mildew resistant
strain (Market More 76).

I have some "compost" that probably has fungus in it also. Can I do
anything with that? I have some glazing for a solar collector I wont
need till winter, heat???

I agree, it sounds like fusarium, however it may be cutworms. I'm having a
really difficult time controlling them this year. I'm spraying each emerging
plant with Bt, but with the daily rains it's almost impossible to keep up.

Look at Park's Seed web site they actually give disease resistance for
different varieties.

Downey mildew is what all of our gardens get at the end of the years as
the weather cools and the plants get wet. (With this in mind, try not to
wet the leaves on tomatoes when watering.) I don't know what you mean by
glazing but nurseries and hardware stores will have clear plastic
sheeting for sale. Be sure to bury the edges of the plastic with dirt.

Got it.

Hmmm. I've been watering the leaves when I fertilize weekly,
something I have just started doing. I take it that this is OK as long
as the leaves dry, which they currently do quickly.

Which brings me to a fertilizer question I've been meaning to ask. I
looked around a bit and didn't see many options, so I took home some
Miracle Grow Tomato Plant Food (18-18-21). It seemed to me that the
organic benefits are mostly in the lack of insecticides. I've been
watering my small garden of cukes, carrots, tomatoes, snow peas,
blueberries, a peach, a grape, cantalopes and one zuchini and one pepper
with this once a week. Is there a better direction for me, this late in
the game?

I don't know what you mean by

Just clear "plastic". For solar, transparency and UV resistance is
key. You may have noticed that clear plastic is milky, unlike the bag it
comes in!

Not good, helps set spores for more opportun moment.

This is about six times more fertilizer than you need. Chemferts are
salts and salts kill mirco-organisms. Go to organic fish emulsion
(organic in this case means no mercury, lead, DDT, dioxin, or
polybrominated diphenyl ethers [PBDEs] ) or manure

I'll look for the fish emulsion, I suspect I'll need to hunt it down as
I don't remember seeing it in the big box stores.

polybrominated diphenyl ethers [PBDEs] ) or manure
http://www.plantea.com/manure.htm .


I used a bit of bagged cow manure. But mostly mushroom compost and
whatever soil I had that looked good. It looks like next season that
I'll rake in more cow manure. Or can I just dump this on top?

Thanks,
Jeff

Yes, rake it in (top 2") and water. The nitrogen in manure comes from
proteins (diet and bacterial) that break down. When protein breaks down,
an amine group (Ammonia. w/ perhaps with another group added) is
released. In many cases this is just ammonia. It is a gas that needs to
be disolved in water to make it available to soil bacteria.
