The way they are invasive is if those very tall stems fall and come in contact with the ground, they root very fast and they continue to do that... thats how they become invasive. They definitely spread if not contained like yours, especially bad in the wind.
perhaps, however if you read the long videos discretion under the video, that does not make them invasive. or Tomato plants would be on the list lol. these are used for chop and drop and compost tea, so if you are maintaining them and utilizing them as intended, they will never have a chance to flop over and take root. I believe anyone growing plants should be making there own fertilizer. Thanks for your input.
I’ve seen vids from tropical Hawaii and some folks had trouble controlling the spread. It was everywhere. I live in the Northeast US and am gonna give them a try this season. I think our wacky New England weather will keep them at bay, similar to yours.
Do you know if they grow well in crappy soil? I have a spot in my yard that I cannot get anything to grow. It gets tons of Fl sunlight there, which could also be my issue.
Mine accidentally spread when I use them as chop and drop. When the stems are cut and taken some else as mulch, the stems will root. Maybe that’s why some people call them invasive.
How long does it take for Tithonia to grow??? I’ve planted mine about 3 weeks ago I do see growth but it’s not anything substantial just yet. Not sure if I planted wrong or what.
Where did you get that info from? It is not a sterile plant. You can buy seeds for it at Walmart or Home Depot. It is one of the easiest US natives to grow from seed. As easy as a melon, squash, or sunflower.
@@woofpuppyThat is a different Mexican sunflower (thithonia rotundifolia)sold as seeds at the store. You have to use cuttings to get these (thithonia diversifolia) he’s showing you. I bought some cuttings off ebay and they’re doing great
Just bought some seeds. Got ripped off then. I might try n grow them. Although in NSW Australia they are invasive weed. So called because their seeds spread so far according to the NSW gov website. Very confusing as they have the same name.

@@TheFrugalHugelGardener Where we are tomatoes are annuals and Mexican sunflowers perennial so tomatoes are killed off, Tithonia Diversifolia is not.
I had placed a lot of info in the videos description. thanks for your input.
@@suzclarke tomatoes are perineal only the climate prohibits their establishment as such.

I was about to purchase these seeds in eBay. Glad I found your video. You saved me the trouble.
Glad I could help
How did you get the plants? Also, there is a video where a person is cursing them as they take over his property... is that a different cultivar?

I m from India Maharashtra....I have this plant with beautiful flowers
Beautiful! Where did you buy your starter plants?
Hi I got mine from a friend a long time ago.
How long does it take for Tithonia to grow??? I’ve planted mine about 3 weeks ago I do see growth but it’s not anything substantial just yet. Not sure if I planted wrong or what.
that depends, did you plant a plant or cutting? a cutting will grow leaves fast, but it takes a few months for the root system to mature.
Thanks for sharing. How many times a week is ideal for feeding tomatoes from transplant to harvest.
I fertilize my garden twice a week. I fertilize my Banana plants once a month and fruit trees around four times a year.
How exactly would this plant exist in nature if they are sterile?
So where would you buy them of you wouldn't order rhem online?
Thank you Sam for sharing. How can I contact you? I would like to get some plants from you if you have for sell.
If you didn’t want them anymore could you dig them up without them growing again?
yes, if you look at my hurricane video you can see the roots of the ones that blow over during the hurricane.
I think most people have seen the swamp sunflower, which spreads by rhizones. They get them mixed up and think they are Mexican sunflowers.
you are totally right.
very helpful info, thank you. Why do you have wire fence around each? Eva
the fencing is to protect from deer.
They come back after the winter?
In zone 9a they do.
How fast do they grow and when do they flower?
very fast. and they flower twice a year.
@@TheFrugalHugelGardener Thanks. What's the success rate with cuttings?
I do not keep track, but I would say around 95 percent?
I am growing some Tithonia Diversifolia now from cuttings i have read its invasive should i worry?
Mine are Sterile and the seeds to not germinate.
they are great as chop & drop
yes they are, check out my chop and drop and compost tea videos.
How can you propagate to get more if the seeds are sterile? Would love to get some for my homestead
Hi you can only grow from clippings from another plant.

@@woofpuppy I got my Mexican sunflower seeds at Walmart this year. Planting them out this week.

Hi John, The Tithonia Diversifolia are Sterile Cultivar and Non-Invasive . make sure you have a right variety. Good Luck.
Yes I have been trying to find this in Darwin , so bloody hard 😬
What area are you in? I see banana trees
zone 9a north central Florida.
Hello, do you sell cuttings?
No, sorry
