Corn? veggies Thanksgiving.

Post  CarolynPhillips on 9/21/2010, 6:29 pm

Has anyone every grown corn in a pot?
Does it have to be extremely warm for corn to produce? Or can temps be around 55 ish at night?

I just had a crazy idea for Thanksgiving. I did not get to grow a garden this summer. I lost my deep freezer in a fire so no point growing if you can store it.
I want fresh corn on the cob for Thanksgiving. I will already have a heated
greenhouse ----
Do you think it can be done? Just 12 or so Dwarf variety plants. (4 to 5 ft tall)

I already have plans to grow a few greenbean plants in the greenhouse too----I like fresh
green bean stir fried.

The 55 degrees at night won't hurt it.

But, long season corn needs to spend over 1400 hours above 50 degrees to reach maturation. Short season, a little less. Can you accumulate that in 2 months?

It never hurts to try. This summer I grew corn for the first time since I moved to this zone. People always tell me that you can't grow corn here. The one I tried had the shortest growing season requirements of any that I could find. The mistake I made was putting it where it got too much afternoon shade. I was thrilled that I did get three cobs from it...one for my husband, one for myself and the earwigs got the other. So if you can find a short season variety as well as a dwarf one, who knows. You might get at least enough for dinner. LOL!!

I would give it a try myself but have a back-up plan just in case.

Good luck!

Bah ...you can grow anything in a pot ...give it a try.

Temp may be a problem ... but nothing ventured, nothing gained

Would using one of those tomato water towers or just plain plastic cover help?

They're goin to be in a greenhouse.
Early Sunglow--- Dwarf ---I think takes 60 days


Gee Boffer-1400 hours? blows my mind to shreds when you put into hours. Oh crap. pale



thinking

I have to try. I will use two 25 gallon pots. Put about 6 plants per pot.

What is the surface area of your 25 gallon pots? You can put up to 4 plants per square foot if you are planting dwarf varieties. Also, in a greenhouse, when your corn tassels, and the new ears get silk, you might want to gently shake the tassels from the top so the pollen will fall down on the silk of your corn. If you don't help the corn out, no fertilization, and then no kernels of corn.

What about in a box instead? I know they discussed that last year over at gardenweb and it is doable. Here is the link http://forums2.gardenweb.com/forums/load/contain/msg051331506877.html

the 25 gallon pots are 2 feet across.

I can try closer planting----It's all experimental anyway---right?
I can put a seed every 6 inches in the pot in all directions---uniformly and get
about 16 seeds in. Some won't germinate. Will accept what ever does.

shinjite: thank you for that link. that was very interesting. long reading--but worth it.
I have an EB What a Face but it is a small one.
At least our thoughts of closer planting is in line of what they were saying at that link.
And the pictures that were still available were very nice.

We know I can grow corn in a large container-----now to see if I can get a harvest
in a Heated greenhouse during Falls cool weather.

You might have to supplement the lighting in the area where you put the cornbox. Fluorescent lighting should work.

I searched and searched and searched.

wow---I had no idea --some of the things I have read and seen.

some man was growing one stalk of corn in a 7 inch pot. and it grew 8ft tall and produced.
he did a lot of watering. that was very interesting.

So what I have found out ------The corn only needs about 7 to 8 hours of sunlight per day.
One plant per 2 gallon is best but can get by with 1 gallon of soil per plant if watered every day. Of course----would have to manually pollinate. Heavy feeders after 2 feet tall.
Must water a lot during silking and after til cobs mature. do best with a fertilizer equal to 15-30-15.
If growing during Fall---would be better for the plant if watered with warm water.

I have sown the corn. I have (4) 25 gallon pots. Two of them have 16 Early Sunglow corn. Two have 16 Ambrosia corn. (64 seeds) .

I have also sown Smeraldo Pole Green Beans. 24 seeds in a 3x7 bed in the greenhouse.

If you're not searched out, you might look for the amount of Growing Degree Days (GDD) that your variety of corn needs. I'm not going to say anything more about GDDs cause everybody just rolls their eyes and yawns yahoo

I don't mind GDD. I do GDD for tomatoes.. Accumulated Heat Units.
But it is always difficult to figure out how many that will be in the Fall cause
we may have a whole week of warm weather then a few days of cool weather.
back and forth like that. Hard to predict. Our first frost isn't until near the end of Oct. It only last a day or two then it's warm again. We might get 4 frosty nights in November. The rest is fairly warm--------and extra warm in the greenhouse.

But will look it up anyway.

My town of 5000 has an automated weather station that posts temps and accumulated GDDs in charts and graphs everyday. But it's for the PNW

Here's the link. It might give you ideas for where to look for one in your area.

Early Sunglow requires 1555 GDD to mature.
My tomatoes require about 1600 GDD

How are you going to handle the watering Carolyn? Maybe run a couple of irrigation lines and use a timer or a waterpump, a downspout and a timer?

I have not found a list of GDD for different veggies yet.
I must be searching the wrong way.


But to the best of my calculation and GDD for The Early Sunglow using
the greenhouse temps, it will take about 86 days.
The GDD Tbase for corn is the same as tomatoes.
So I used the Modified Growing Degree Days calculation to come up with
86 days.
High temp for day is 86* Tbase + low temp for day is 50* Tbase= 136
136 divided by 2= 68 degree average temp - minus 50 degee base= 18 GDD.
1555 GDD divided by 18 = 86 days.

When night temps are above 50*, the days to maturity will be shortened. And we will have many nights above 50 and the greenhouse will be set
between 55 and 60.
So- If I use the greenhouse temp night time high of 55 *, it could take 76 days.

You and me both.

I keep forgetting you can control your ambient temperature-I'm envious!

I recently read an article by a local celebrity gardener that folks in my area should take the 'days to harvest' number on the back of seed packages and increase it by 50%. How depressing is that?! Mad

Not me, I'm from the PNW too. Heat units and light hours are VERY important to my success (or lack of)

Boffer-----that is very depressing.

I called my state corp-extensions office----They cannot find a list of
GDD for different veggies either---but they are looking into it further and will
let me know what they find.
They found in their files all the GDD of our entire growing season but not what each plant requires.
