All my edible's are dying

 


Evening Ladies and Gent's
This year I have dicided to get myself a greenhouse and grow some
tomatoe's etc...

Everything is working great untill the plants started fruiting, I got
some nice tomatoes comming thru. I have started to know little black
speckles forming on the bottom of my tomatoes, and then they are
turning bad and mushy, Can anyone suggest something for me to try?

Also my Pumpin's,marrow's and butternut squash had nice big flowers,
then the big flower heads are dying and snapping completly off the
stalks,

any help on this matter would be great, this is really starting to
annoy me,
They all have lived and grew nicely in my greenhouse, for last few
months,

Regards
Richard

Sounds like a fungal problem.
How humid is it in the greenhouse?
Is it getting plenty of air flow?

That would be a good chance but there may be more than one problem, hard to
say without seeing.

Also how would the curcurbits get pollinated?  Can bees get into the
greenhouse?  Are you doing it by hand?

Could be blossom end rot, which is a problem of low calcium availability
in the fruit.

(/quote from http://ohioline.osu.edu/hyg-fact/3000/3117.html )

Blossom-end rot is induced when demand for calcium exceeds supply. This
may result from low calcium levels or high amounts of competitive cations
in the soil, drought stress, or excessive soil moisture fluctuations which
reduce uptake and movement of calcium into the plant, or rapid, vegetative
growth due to excessive nitrogen fertilization.

Management

   1. Maintain the soil pH around 6.5. Liming will supply calcium and will
increase the ratio of calcium ions to other competitive ions in the soil.

   2. Use nitrate nitrogen as the fertilizer nitrogen source. Ammoniacal
nitrogen may increase blossom-end rot as excess ammonium ions reduce
calcium uptake. Avoid over-fertilization as side dressings during early
fruiting, especially with ammoniacal forms of nitrogen.

   3. Avoid drought stress and wide fluctuations in soil moisture by using
mulches and/or irrigation. Plants generally need about one inch of
moisture per week from rain or irrigation for proper growth and
development.

   4. Foliar applications of calcium, which are often advocated, are of little
value because of poor absorption and movement to fruit where it is
needed.

The first thing I would suspect is a lack of pollination.  Do bees have
access to the greenhouse?  If not, then you will have to hand pollinate
the squash.  

They could also be suffering something like blossom end rot, or otherwise
aborting fruit due to nutrient or temperature stress.  How hot does it
get in the greenhouse during the day?

(Hope I have caught all the typos, as I have injured some fingers on
my left hand, and I touch type...)

I'm replying to this post with my tomato problem since I'm getting an
error message trying to post a new message!

Two of my tomato plants suddenly went into total wilt. I've never seen
this type of wilting problem. Last year in a different spot I had some
wilting disease that started at the bottom of the plant and they
responded a bit to extra watering, for a while, before they expired.
These tomatoes are wilted top to bottom, no leaf discoloring. I'd
appreciate any help identifying this problem and either a cure or
future prevention. This is only the second year of planting tomatoes
in this area and so far the other plants near these two affected ones
are doing fine.
I'm getting a lot of strange things going on in the garden this year -
plants that don't look healthy, black spotting on a brand new,
expensive hydrangea and almost overnight major increase in black
spotting on all my roses, other perennials that just don't look right
etc.
I'm an organic gardener, so any help in that direction would be most
appreciated.

Thanks!
June
