Plant Nutrients

Thanks Steve...

Here is a good plant nutrition question for anyone out there...  The
problem I typically run into with my pumpkins, and my garden in
general, is iron chlorosis occurs early in the season when the
temperatures are a little cool for good plant growth.  The leaves
yellow between the veins on a couple of the early leaves and the
overall growth is slow until the season warms up and then the plant
starts growing and everything looks great.  In the mean time the
yellow leaves just are unsightly for a while, this year stretched this
out longer than normal.  Has anyone applied iron either foliar or drip
irrigated that solves this issue?  I have applied some and don't see a
response very often, but wanted to know what other people may have
come across.  The soil test iron is high, but just unavailable in the
cool spring season.

Quoting Steve Haberman <shaberman@insmgt.com>:


Correct Shawn. Too much Nitrogen causes the plant to cast of N particles in
a process called guttation. This dehydrates the plant hence yellowing then
browning of the leaves. Therefore, we can say that yellowing is a secondary
result of too much N. It has been awhile since I received my Biology degree
fom Colorado State University. Glad you corrected me.

Chlorosis (yellowing) of the leaves can be a number of different

causes...if

the new leaves are yellow it may be sulfur, if the old leaves are turning
yellow then it is usually nitrogen.  If the yellowing makes the leaves look
striped (either in between the leaf veins or the veins themselves) then it
may either be zinc or iron...  There can be others that make this problem
occur, but most likely it is one of these culprits.

Depending on how much water you have been giving your pumpkins they may

just

have too much water...and this could cause a nitrogen deficiency.

Too much nitrogen does not cause a plant to yellow...sorry to jump on this
one Steve.  To much fertilizer, nitrogen in particular, will cause

excessive

vine growth and delay the maturity of the plant.  Besides too much
fertilizer will also force the plant to use more water, usually because of
the excessive vines.

Too much water or too much N can cause yellowing. It is hard not to want to
pump both to your plants. I would guess too much fertilizer.

Also, some of the leaves on a vone, not the vine with my big fruit on it,
but another primary vine has leaves that have started turning yellow. What
nutrient in excess or defeciency cause yellowing of the leaves? Thanks

What exactly does pinch mean? Do I just snap the end off? Or do I bend
the end? My concern is that the integrity of the vine will be
compromised and allow bacteria or virus deposition into the opening in
the vine where the hole will be from pinching it. That was my
reasoning for just removing the blossoms from the female fruit instead
of removing the fruit itself- a hole was there.
Wow-the tertiaries are still growing? Amazing are these beasts of the
giant pumpkin world-

A few days ago I buried the secondary and tertiary vines of my Giant.
Now am I supposed to bury the end of the primary vine?  I never
pinched and buried, I just buried the others. That was the first
night the pumpkin had no growth- I measure daily, not weekly. What I
did to the primary vine was removed all the female blossoms. There
were quite a few. The vine grew another foot and added a new female
with fruit. I culled that fruit and once again, the primary vine
grew another foot and added yet a new female. I do not want all this
energy to be diverted this way. Should I bury the primary vine as
well? It is currently 23 ft long and the fruit is 8 ft from the
base/

mound.

Please advise
