Clone a tomato plant (and fill your garden for FREE!)

Clone a tomato plant (and fill your garden for FREE!)
For this instructable, I will show you how to increase the amount of produce you can grow at your home for free.

Cloning may sound like a very complicated scientific process, but for the at-home gardener it is a very simple thing that anyone can do.

Step 1Materials needed

Materials needed
The actual list of items needed to clone a plant is very short and anyone who gardens will have no problem at all locating these items around the house.

Absolute must haves:

A semi-mature tomato (Donor or mother plant) A plant with good growth and that has not been diseased or stressed.

A container or containers around 2 inches deep (I used one of my wife baking dishes, Ha ha)

Razor knife

Potting soil

Water

Other optional items :

Rooting compound (can be found @ Wal-mart for 6 dollars[U.S.])

Humidity dome

Seed heat mat

I realize that most gardeners probably have the humidity dome and seed mat, but I was aiming this instructable for the weekend warrior gardener in hopes of expanding minds and showing how simple and cost effective this act of cloning can be. The optional items will greatly speed up the cloning process BUT are not required to complete this process.

Tomato plants do not need to be cloned, all the little nodules on the stems are the beginnings of roots. You can break a stem off stick it in dirt or water and it will take root.

I would have given it a try this year but an early unexpected frost killed all my three mother plants :( next year my mom and I are going to try this. You're right about showing gardening to kids; I love working out in the garden with my mom!

da am cerut mai multe explicatii la modul cum a fost obtinuita acea pasta alba.desi sunt un om sarac nu ma la batut in fata destinului tot ce vreau sa fac e ca sa pot sa supravetuiesc eu si familia mea.am citit comentariile ,dar as vrea sa stiu daca aceste plante supravetuiesc in solarii sau pe camp liber.cu mult respect pebtru voi,"gelu"

Google Translate sort of says: "so we asked for more explanation on how that white paste was obtained though a poor man does not beat me in front of destiny all I want to make is that I can survive my family and I have read comments, but I want to know if these plants survive in greenhouses or open fields with great respect for you, "Gelu"".
Gogutu, do you have someone who can translate to English?

Has anyone tried grafting tomatoes to cloned rootstock?

I am beginning to play with cloning, but I'm playing with OTC varieties, and not the expensive rootstock, such as maxifort or beaufort. This is also for my own personal garden, and not a commercial endeavour. If I get successful with my grafting, I might play with grafting clones myself.

I love this. I think it's so neat. Do you think you could clone a pepper plant?
I would assume that tomato plants (right now ,being late May ) are too small to take cuttings from. Does anyone know if you could take a cutting from below? i have little flowers growing on my tomato plants but afraid to cut off the top, even if it grows roots, will it damage the flowers in any way?
Apr 26, 2011. 10:22 PMfinton says:
AzureEyes, if you are taking cuttings you should remove all flowers and flower buds, and most/all of the leaf area, as flowers and fruit are nutrient "sinks" and your cuttings will have to provide that from stores in the stem until the roots establish - which they probably won't as the roots need those stores to get established themselves.

You should use a rooting hormone for all cuttings & tissue culture work. The name is"Giberallen" it works about 95% of time. God one. Cheers Kiwi
Oct 22, 2010. 3:55 PMfinton says:
Gibberellin, kea. See http://en.wikipedia.org/wiki/Gibberellin for a far-more-scientific-than-you'd-ever-want-to-know article.
This is a good Instructable tonysoprano! Hopefully it will encourage more people to get into propagation. Your "Selecting starts from the bottom stems of the plant have a better chance of producing roots because of increase in natural rooting hormone in the plant" is correct, but also because the shoots further away from the root/stem interface are more "adult" (less old, but more "adult") and contain more auxins - "An important principle of plant organization based upon auxin distribution is apical dominance, which means that the auxin produced by the apical bud (or growing tip) diffuses downwards and inhibits the development of ulterior lateral bud growth, which would otherwise compete with the apical tip for light and nutrients. Removing the apical tip and its suppressive hormone allows the lower dormant lateral buds to develop, and the buds between the leaf stalk and stem produce new shoots which compete to become the lead growth. This behavior is used in pruning by horticulturists." (Wikipedia); ironically auxin is also used as a rooting hormone! Plants: go figure.
If I can find the photos, I'll do an instructable on propagation using leaf base buds based on a potato propagation project from my B. Hort (Tech) (Hons) honours year - I grew thousands of plants from just two different tubers!

Yes, Great stuff. I am sure instructable on this would be good value.

 there is a good way to do cuttings from almost any plant.
after taking the cutting and doing it in grow hormone  and putting it in your soil (best 50/50 sand and peat mos ) place the container in a clear plastic bag .
Put some sticks on the side to support the bag and tie the bag close and leave for two weeks in a light but not in the sun place make sure the soil is well watered but not to wet.
no need to water them at all.
also cut half the leaves so there is less leaves to feed.
Some plants are hard to do but I know another way and will post that later.
Hope you have lots of fun doing it.

Will this work on fig trees. I've tried everything I can think of. The branch grows roots but as soon as I cut it off the tree it dies, roots and all. gma
Oct 24, 2010. 1:32 PMJodie123 says:
Don't know what went wrong with your figs but try another way of doing it.
There are more way's then one to skin a cat lol
Sorry for the late reply was not aware of it it was the first time i ever posted anything.

Well that's strange sueL2: I chopped up my 1.5m (5ft?) fig-in-a-barrel last autumn, cut the thumb-thick branches into 500mm lengths, more or less, took off all the leaves, and stuck the stems in spaced out groups of six or so in tyres full of garden soil; this spring I have about 20 rapidly growing figs, having lost maybe one or two. No air-layering, hormones or anything! I'll try to remember to post a photo.
Mar 27, 2011. 7:15 AMsueL2 says:
Hi Finton
I tried your method. It looks like it worked. No leaves yet but it looks like it has buds. So easy after everything else I tried didn't work.
Thank you!

I also have 4 apple trees I started from seeds. They're about 2 inches tall. How old or tall do they have to be before I can plant them outdoors?
Apr 26, 2011. 10:17 PMfinton says:
Sorry about the delay sueL2: just got back from PNG. Well strictly speaking, any old age/height you like; they do grow from seed in the ground after all! :] The answer depends on pot size, climate, site, intensity of after-planting care, etc, so let's see: personally, I'd grow them on in the pots until the roots are filling the pot space, but have not started to get crowded. This will give them a head-start over weeds etc, and give them a bigger volume to extract moisture from. I'm assuming you'll use standard planting methods, rather than just bunging them in the ground...
Keep in mind that apple trees started from seed rarely produce true to type, unless they are an heirloom variety that has not cross pollinated with any other variety. Most nursery-produced trees will be a good fruit-producing scion grafted onto disease-resistant and/or dwarfing rootstock (do a Google search). If your seedlings grow well in your site, you could always top-graft them with another variety when they're big enough.
I have some apple seedlings growing from broken roots left when I shifted my two grafted apple trees - these will be from the rootstock, so I intend to do just what I suggested above. I have also grafted scions from a old heirloom variety onto the existing trees; the grafts have taken but I've had no fruit yet.
Mar 26, 2011. 10:40 PMfinton says:
OK. Here are the figs in a wheelie bin, and about 20 of them after cutting the branches into lengths and "stikin" them in soil filled tyres (to the left of the bath in the second pic).

The other poster is right about needing to Air Layer a tree, but it's not as difficult as he makes it sound. Message me if you can't find good info, and I'll explain the process. All you'll need is a knife, sphagnum moss, string and plastic wrap.
Jul 25, 2010. 4:37 PMsaintneko says:
Most trees can't be cloned this way. You should look up the technique known as "air layering" (the way many bonsai are cloned) however, be warned, the technique is difficult.

I would not be concerned about using a rooting hormone (at least, a natural one), as rooting hormone is something that is normally in the plant anyway.

Perhaps some of the rooting hormones are synthetic--that might be cause for worry, but if it is an exact duplicate of rooting hormone (chemistry wise), again, I would not be worried. 

How much rooting hormone does it take to cause cancer in some test animal? 

How many tomatoes would you have to eat to get an equivalent dose?

Does it build up in your body or is it excreted regularly in some fashion?
Mar 14, 2011. 8:11 AMrhkramer says:
Do you wait until the suckers attain a certain minimum size (before cutting them for cloning)?

What size do you recommend?

On the plant I want to clone, the suckers are growing out exactly in the V between the main stem and a "leaf stem". In your picture, it looks like the sucker is growing from a place an inch or so out on the leaf stem.

Will that happen later on my plant?

Should I wait for that to happen before cutting the sucker?

willow branches contain an excess amount of natural rooting hormone, so if you wanted a non-carcinogenic option for edibles, you could use those!
Oct 22, 2010. 4:01 PMfinton says:
Yeah, Salicylic acid (from the willow genus name Salix). What aspirin is made from more-or-less. I seem to remember that you can use aspirin as a rooting hormone..., must check on that...
Wikipedia's Salicylic acid article also says "It plays a role in the resistance to pathogens by inducing the production of pathogenesis-related proteins. It is involved in the systemic acquired resistance (SAR) in which a pathogenic attack on one part of the plant induces resistance in other parts." This might be interesting to research also: infuse willow bark and spray on the veges as a pathogen preventative...?

I use to pick off the nodes and stick them right in the soil under the plant. I'd have about a 50% success rate with minimal work. If the clone is alive in a week I'd pull it out and re-pot. Tomatos and peppers were the only plants I could clone without a rooting hormone and humidity dome etc.

"my wife baking dishes" oh dear, you bake wives often enough to have a special dish for it? :D nice instructable, though :)

Years ago I had my own plant nursery business for a couple of years, during which time I probably grew a few thousand rooted cuttings of various ornamental plants. I used a lot of rooting powder, but that doesn't mean you should. And especially for things you are going to eat, keep all "chemicals" away from your (hopefully organic) garden. (If your gardening is not organic, be ashamed. Be very ashamed. And resolve right now to do your reading about the whole matter. Don't go organic because I tell you to - do it because you have informed yourself and you know it is the right thing to do.) Okay, to the point. One of the very best things you can have in your garden is peanuts. Get a bag of raw peanuts at the food store, and almost every one will sprout. Prepare little pots about 10 days before you are going to clone your tomato or pepper plants. Put into each pot some relatively sterile growing medium, very mature compost is okay if very mature, mixed with some vermiculite and/or perlite. Put a peanut in each pot. When the peanuts are up, the pot will be full of natural baby plant hormones. Make your cuttings and put one in each pot, so that the node at its bottom end is adjacent to the new peanut sprout. As the peanut plant develops, it will be colonized by nitrogen-fixing bacteria, which will give nitrogen to the tomato plant, which will grow like there's no tomorrow. Put peanuts next to everything in the garden. There is only one drawback to peanuts in the garden - they attract grass, which loves nitrogen. So if keeping the grass out of your garden is a concern, you might want to surround the garden with a barrier of very heavy mulch before planting the peanuts, or a physical barrier even, if that seems necessary.

fenris... I love, love, love that suggestion and can't wait to try it out. I suppose I'll need to wait for next season to plant the peanuts, tho... If you can point me to any online resources or references, I'd really appreciate it. I'm in southern California, so growing seasons are long and the gardens are never empty. Would peanuts be a good green manure?

Anyway. Thanks for posting this!
Sep 18, 2010. 5:25 PMfenris says:
I could be wrong, but I think you can start peanuts anytime in socal. I live in Florida, and we had a terrible winter this past winter, and I had voluntary peanuts coming up all over this spring - which means that the peanuts in the ground survived. If you don't get frost, the peanut plants will just go a little dormant during the coldest weather and will grow vigorously again when the temperature warms up a bit.
Any given peanut plant can have quite a long life. Let me explain. After a peanut plant has been growing for some weeks, you will notice that all the stems are rooted here and there into the ground. If you wanted to, you could sever all of them and kill the original plant, and you would have several plants - so okay, even if you don't do that, the plant is constantly creating new root systems, and given time will spread all over your yard, and to whatever extent they remain all interconnected you could say you have only the one plant, but it would also be true to say that the plant has reproduced and turned into many plants. Every one of those new plants will make a cluster of peanuts.
As for groundcover/green manure, you just cain't do no better. With a little practice you will be able to get the peanuts with very little damage to the plants, so that they will continue to live and produce more, if that's what you want to do, but you can also harvest most of the peanuts but leave a few here and there, then till the whole mess under. You have not only tilled in some excellent green manure, but the peanuts will come up again and start the process over again.
I spose I should say here that if the result is a big imbalance in the N-P-K ratio, blooming plants might show some lack of eagerness to bloom. The peanuts keep adding nitrogen, but they aren't adding much phosphorus or potassium. Go to where somebody is trimming banana plants, get the trimmings for potassium, and go to where the tree trimmers are running a chipper, and get some of those tree chips for phosphorus. That chipped tree material is great mulch, lasts longer than some mulches, but also provides some phosphorus as it does slowly decompose. That is exactly the way it happens in nature, therefore it is the right thing to do. We are sometimes wrong, but Mother Nature never is.

You said we should cut it where the branch forms a "V". Where exactly do you cut off the clone? Before the V starts (near the main stem), or after the V on one of the branches coming off, or, right at the V, cutting it in two? In other words, should the clone look like:

1. --<         (before the V)
or
2. ---            (after the V)
or
3. /      \       (the "v" split in two)


Thanks for your help
Jul 31, 2010. 3:18 AMredhawk44 says:
Always cut at the very bottom of the intersection with the main stem and be sure to include the small bud like new growth. Doing this will remove the need for growth hormones as they are already there in the bud.
