There are no buds on it to grow into a tree. Looks good though. Ill give it a try.

Steve

I did that with a tomato leaf once. It grew roots and stayed green and healthy looking, but never formed any new growth.

Never tried it with a single leaf.

Here's a lemon cutting I rooted in water last summer, no rooting hormone. Took 6-8 wks to get the roots.

Sometimes you might get a leaf to grow roots, but it will not be able to generate any leafy growth or shoots -- so what's the point? It's interesting (convenient?) that he doesn't show that happening in the video. I would think this would not work with citrus. But prove me wrong!

We know it's possible to root cuttings, so I would go that route.

There are some plants that will root and 'shoot' from leaves -- like begonias, for example, or some succulents. But in general, in the plant kingdom, rooting from leaves is a very rare ability.

I believe I read a post on here asking this a way back and its a genetic dead end....cutting is hard enough

Not a dead end. I have made progress using only leaves from my ponderosa need hormones tho. Some varieties grow even faster from leaves than from seeds. Wish he would have shown the result in this video. Still an informative one - This topic in general is not much talked in public - interesting experiment all in all. Someone ask this dude to make an follow up video so we know its not a scam?

Actually this has just jogged my memory. I'm pretty sure I remember the user "Greenman28" posting about a pachira (money tree) that he grew from a single leaf.

Just did a quick search and here it is... maybe you could ask him for tips, he's a very skilled and knowledgeable grower.

From what I have read, it is possible to root citrus from a leaf. (But not necessarily easy)

The leaf will need to be somewhere with constant warmth, maintained at the right temperature range, and humidity will need to be maintained as well. Best to have the part of the leaf that is to root not be exposed to light. Rooting hormone would be helpful too.

Some citrus types are much easier to root than others. (Generally the more vigorous growing or drought resistant the citrus is, the easier it will take to rooting)

To be successful, you are most likely going to need a temperature thermostat. Also, red LED light illuminating the leaf would probably be ideal, since it can give energy to the leaf without discouraging formation of roots.

It is much harder to root citrus from leaves than it is from stem cuttings.

Responding for floral_uk. Unfortunately I did this experiment more than 5 years ago and life has changed a lot from those times - dont have any pictures nor the plants with me anymore. But I still remember eventually that they started to grow meristem from base of the leaf - If I remember correctly it took months though. Its definitely citrus type related thing - some of them wont root at all

Seems like a scam. No-one can grow a plant from a single leaf. Or it might grow if you inject it with steroids and hormones. Good luck with your project!

Lots of plants can be grown from a single leaf. But I'm not convinced citrus is one of them.

Very interesting. Thanks for sharing.

Although even if it could be done I would hate to wait forever for it to turn into a tree. If I was a kid I would probably try it. I might even have my little nephew give it a shot. He will be around a long time after I am gone. Now, I like to buy trees or root cuttings for quicker results )

It has been long known that rooting a citrus leaf is a dead end. There will never be further growth

Citrus; I had a citrus tree with monster thorns and one of those thorn split its tip and grew a thriving branch. I will look for the pictures.

Steve

Now that is interesting Steve

I posted a picture on the citrus forum somewhere but I don't remember where. It was on this tree on the left hand side not quite half way up.

So has anyone succeeded in this?? A lot of yes and no in this comment sectionn... Im just thinking how economical way this could be if its real

You need at least one node or bud for it to grow into a tree.....

its really that simple.

steve has the most interesting topic with new growth off a thorn..

Genetically, a thorn is a modified leaf,. Although not common, a thorn does rarely produce a leaf.

This fella proved us wrong. Look at this clip, he got them growing roots from a citrus leaf. what the heck. https://www.youtube.com/watch?v=X65uqMYD0V0

He proved that a root can grow from a leaf petiole. But he didn't prove that a plant can develop from that.

It has been long known that a citrus leaf can produce roots. No one ever said that a leaf cannot develop roots. No matter what, the leaf has processed as far as it possibly can. It will NEVER grow any further.

Looks like OP has not ended his experiments. Found his latest Citrus Leaf clip https://www.youtube.com/watch?v=2jr8qmeXHOk&t=12s

Seems legit? Can you use those roots to glue them to a real stem and then grow citrus, this fella makes me curious as hell

Look at this and it will explain the thorn issue

Can you still use the roots in grafting, like lets say you grow heck of a root system with single leaf and cut it off and graft onto something else. And btw I see a stem in this picture,

For what it's worth, I have a very large makrut lime that is a rooted from a piece of root that got detached. What happen was, the seedling was in a 1 gallon pot set inside a larger 15 gallon pot. The roots grew through the drainage hole and into the larger pot underneath. When I removed the 1 gallon pot, I had to cut it off and a piece of the root remained in the large pot. It eventually sprouted leaves and is now over 4 ft tall. Has anyone had this happened before?

Although not common, propagation from root cuttings is a known technique but does not have a high success rates. I have not tried with citrus family but I have done that mostly for various ficus and elms with good success rates. In general, plants that send out suckers easily are also good candidates for propagation by root cuttings.

You probably could get a shoot to grow from a rooting leaf if the leaf is cut with a sliver of stem holding the axillary bud.

I have a 4 foot tall Eureka lemon that I started from a leaf. It is getting buds on it now. It is just under 2 years old.

Then your the only person in the history of mankind to do this. Why do I have serious doubts?

Dar Sunset Zone 18, sprouting shoots from roots cut off definitely happended a lot in my citrus nursery when the roots established well in the ground. The regrowth was very impressive and now that I am looking into doing bare root transplants I'm looking into doing this on a larger scale.

Silica I had a seed grown sweetlee tangerine tree grow a branch out of the tip of a thorn. I lost the pictures to this or I would post it. Strange things do happen.
