I think it's worth a shot!

Nah, it's not too late. I just sowed some a couple weeks ago. They'll get a late start, but if we have as long a growing season as last year you should be ok. Now, I'm only talking about the flowers. I don't know how long the veggies will take to ripen.

I just planted seeds a couple of weeks ago and we are way ahead in the season. I read planting pumpkins at the end of June was the right timing for Halloween. I just planted out my zinnia seedlings last night.

it might be too late for big pumpkins to really get big, but that doesn't mean they will not grow. last year i kept track of what the seed packages reported as days to bloom vs. what i actually saw happening--those packets were remarkably accurate. worth a look. things like cosmos can go in very late and still have a nice flowering season. things that take a hundred days, well, you need to have an idea of your first frost date if they would be affected by frost

I never start my pumpkins before June 20th (my sons birthday). The first two years I grew pumpkins, I planted them in the spring and I got pumpkins but they were rotten by Halloween.
I do have one vine that grew up from last years pumpkins (I admit it, I am a dismal failure growing them from seed when I try to plan it--I only get a few small pumpkins and they just WON'T grow big for me!) and it already has babies on it growing like crazy. There is no way they will make it to the end of October, but one can dare to dream, eh!

Growing Big Halloween Pumpkins

Location - sunny with lots of room to spread. A weed patch is perfect.
Dig a big hole about 2 ft deep. Don't worry about the weeds.
Fill each hole 1/3 way with composted manure.
Cover that with hay or leaves, then add soil to nearly fill in the hole. Build up a little mound in the center of each hole.
Plant 3 seeds in the center of the mound.
Cover with hay.
WATERING:
Fill the well around the mound twice with water every day.
As the plant grows, the roots will reach down to the manure.
Water, water, water.

When the vines begin to grow long, arrange them how you want them to grow and then don't disturb them again. The vines will make roots where it comes in contact with the soil.

When they begin to bloom, there will be male and female flowers. The females makes the pumpkins. For larger pumpkins, pinch off all but two or three little pumpkins when they first begin to form. For an even bigger pumpkin, pinch off all the little pumpkins but one. All the growing energy will go into these 1-3, instead of ten or twenty little pumpkins.

Don't worry about weeds or grass that may grow up around them. They enjoy a little shade. Weeds also pump nutrients up from the soil below and the vines can access it. Weeds also help retain moisture in the soil as living mulch.

When the vines turn brown, the pumpkins are ready to harvest.

Pumpkins love to grow in with corn. Lots of nutrients, water and shade. Corn loves pumpkins for holding the soil firm from washing and steadying them up so the wind doesn't knock them over. Pumpkin vines also act as living mulch, keeping the corn's roots cool and moist. Both benefit.

Lots of water & manure makes big pumpkins. I add a little potash (wood ashes) to help increase flowering. When leaves and stems begin to turn brown, stop watering. I set my pumpkins on an upside down pot or board so they won't rot on the ground. Early on, set them on their bottoms for perfect shaped pumpkins with nice flat bottoms so they set right.

That's how I do it anyhow. Works for me!
Hope this helps!

I'm still planting nasturtium, sunflowers, morning glories, hyacinth beans, and castor beans. They're late blooming for me anyway. And, I broadcast zinnias, bachelor buttons and cosmos all summer! I'd like to plant kiss me over the garden gate and coxcomb, but it may be too late. Maybe I'll pick up some (plants) at the Farmers Mkt. in Indy next week).
