I'm going to try my hand at growing sunflowers in about a 1/2 acre section of field. I'm going to broadcast them.

Question: can I just cultipack them in? The ground will be freshly tilled so pretty fluffy. Or, do I need to lightly till them in about 1"?

Yes you can cultipack.... The more important part of all of these

1) weed control, read up on what you need for pre and post emergent

2) Deer control. Keep them out.

If you can do 1 and 2 , you will have sunflowers!

Agree on previous post.

I disc heavy, broadcast and drag.

The issue I have had lately is grasshoppers.

They destroyed much of our crop in the last 3 years. They come up nicely, then the hoppers strip the leaves and they die.

Hoppers leave the native sunflowers here in Texas pretty much alone. Non native get ate.

If grass hoppers were a crop in Texas, I would be rich.

You’re about four months too late to plant.

Well it looks like he's in South FL. So he may be right on time.

I would say he needs to get them in the ground before the rainy season dries up. They need a couple of good Sept rains to make. It stops raining down there about the first of October

I planted a blend of sunflowers, millet and Milo that I bought online. Everything did awesome except for sunflowers. I don’t know if I over seeded or my soil was lacking. Hard time believing deer ate all of em, but it’s possible. I sprayed prior to tilling and then cultipacked. Palnty of rain. Not sure what happened.

This late in the game, I would do brown top millet. Jmo.

Yeah. South Florida. Just trying a small patch to see how it goes. If it works, I'll give a stab at it at our land in Alabama next spring/summer.

If there are deer around, I have a hard time believing they didn't

I have 2.5 acres inside a literal deer pen. Like an 8 foot high fence. And the deer are squeezing under it to get in and eat the heads off my sunflowers. I have literally had to put an electric wire 12" above the ground outside a high fence to keep the deer from digging under the fence like dogs. That will tell you something.

I have tried everything to keep deer out. If they find a way in, it doesn't take long for them to wipe you out.

Best post emergent is elite pre emergent. Very limited broadleaf options over the top of sunflowers.

Start clean and spray with Metolachlor and Sulfentrazone at planting, then clethodim and Zidua about 3 weeks later. You’ll probably have a handful of broadleaf weeds break through, but it will be fairly clean.

Won't the sunflowers canopy out and choke off the competing weeds?

No. Sunflowers are one of the least tolerant crops on weed competition. They need clean ground.

Sunflower guys are huge crop protection nerds. They talk about all sorts of pre emerge combinations, and Clearfield traits, and tolerances, etc. The rabbit hole is deep.

Sunflowers won't do well if planted in a mix. They won't do well if you don't use a good preemerge weed control program. And they won't do well if they're planted too too thick. And they won't do well without a lot of fertilizer. They like N and K especially if you want to make big heads with high oil seeds.

About the only thing they can tolerate is drought. Sunflowers are a dry weather crop. Grown in Kansas, Nebraska, and South Dakota. In general it takes one good rain to get them going in the fertilize. And one good rain to make heads. That's about all they need.

But they're huge pussies when it comes to competition

Too much rain and they fall over and get fungus diseases. Should be OK in the fall in S FL. But I wouldn't plant them too early. They're really not well suited for tropical climates. The biggest producer in the world is Ukraine. Cold and dry and fertile black soil..pretty much the opposite of S FL in the summer.

It was 63 this morning in Oxford and only got to about 84 today. It's delightful right now. Gonna be nice and cool and dry again tomorrow.

Then 95 and above for at least the next week . Gross. Ready for fall.

Planted some in pots around my house (I think the seed pack was from TSC?), they came up great and bloomed, very little work from me. Pick and put in a vase and the blooms last a long time. Very easy plant to grow in pots.
