So to get what I want. I must develop it

It is estimated that my 6a/6b in cincinnati will pass into 7a in about 30 years.

They don't even grow outdoors in my climate. (8/9) You can grow container citrus outdoors in summer. Not all year round.

So I guess I need to develop it

I'm thinking t about using ponicirus then Cross in several lemon varieties

Will that work

" Will that work "

Probably not. Poncirus trifoliata is often used as a citrus rootstock to increase cold hardiness slightly but because of genetics (different genus, very distinct DNA), it does not hybridize easily or well with any citrus species. And the common name of bitter orange indicates that what potential hybrids could be induced using this species will tend to be less than tasty.

But you may have fun playing around with it if you have the time and patience. Just don't expect great tasting fruit.

That will be part of the foundation stock Cross in several lemon varieties plus I have Clay soil and I want disease resistance I want genetis

Maybe not the first. Five generation but after after the initial crossing with the lemons the flavor could go back to full lemons

If I understand my genetics right

It doesn't. Make much logical sense to call someone names because they are willing to try something different

Poncirus should survive in your zone to reach TREE proportions, I have seen them in Zone 7 NJ and PA. If you add a ton of sugar, they can apparently be made into something edible.

P.S., No reason to call people JERKS here, btw. Those casting aspersions are perhaps better served in alternative fora.

I'm going to hat to breed what I want

check out THIS youtube a man in Nebraska is growing citrus.

Here's my trifoliate orange today in zone 7 Maryland. Nothing eats the fruit neither man nor beast

Any attempt to grow edible citrus in a cold climate like mine will require fruit to ripen before frost.

I looked at the YouTube video. He's not growing citrus in the open. They're in a greenhouse. OP wants to grow them outside.

That's not good enough for me for I'm from the north and not wealthy but I'm not used to not getting what I want and I'm. Willing. To. Take PT for the foundation stock for the breeding with lemons for cold hardiness and deiase resistance and Cross in tho most cold hardy lemons varieties I can get ahold of even if that first get them to cross then push for flavor it's all in the genetics

How old are you? It takes generations of breeding (translate to decades) to achieve what you are after.

I'm 57

I'm sorry to say that despite all your enthusiasm and ambition, what you propose to do will not - or is highly unlikely to be - accomplished in your lifetime.

To me I'm going to go through with this as a hobby. And maybe. A future buisenes. I know it's un likely. But to me that means nothing but I must try and suceed but nobody really knows what can happen unless they have the guts to try

Scilla that is where Pikeville Kentucky but I must. Develop what I want iknow The Harvey lemon is the most cold hardy lemon right now I will need to cross ponicirus trifoliate orange then back cross the lemons in the Cross it might be hard but it takes guts to try what looks impossible but that's a state of mind

Pikesville Ky. Is that near breaks interstate park on the Virginia, Kentucky border.

Can Meyer lemons be large

The tree or the fruit? Both are smaller than your standard grocery store (Eureka) lemon or that type of tree. The fruit not so much but the tree is only about a third the size of a standard lemon.

Meyer is not a true lemon but a hybrid of mandarin, pomelo and a citron. It will produce slightly smaller, rounder, thinner skinned and sweeter fruit than a standard lemon. And with more of an orange coloration to the skin.

I think I have a larger than normal Meyer lemon

The looks too big for a Meyer lemon variety I don't know can any body tell me it has about 16 seeds Howard

If it has seeds, it is probably not a Meyer. They rarely ever produce any seeds and if they do, it is only a very few.

Since there's no scale or measurements given it's hard to assess whether it's "to big for a Meyer." But the seeds and the colour would imply not.

Howard It will cost you less to buy the fruit than to grow your own fruit. Grow something that is too expensive to buy like fig.

They say they have no scale of size this is the best I can do to give some scale of size but the seeds are consistent with 16 seeds what variety of lemon is it

Howard

And I bought them at Kroger this is what the bag. Says but I. Don't know what they are they. Growing much too slow. For eureka lemons

Howard

Thedy are either eureka or lisbon

I'm starting to grow the lemon seeds . Do all lemon seedlings look alike

Hear is my new. Trees

Howard

Looking good Howard.

looks good.

I said I would. Grow new trees

Howard

They are in a clay soil

Lead Farmer 73 has a notable youtube. "you guys in 8A or colder might want to take heed" is good advice. Look at what happened to his trees after the freeze (in S. Carolina). The pix of him harvesting fruit were taken much earlier in the season. My advice to OP is to move your operation waaaaaaay down in Dixie.

Sam Do you mean south of the MANDARIN/Decopon line

My trees have not come from genetlcy modified lemonsi

There are NO genetically modified lemons!! Selective breeding is not the same as genetic modification.

I believe they look a little stressed

" I believe they look a little stressed "

Very likely because you have attempted to start seeds in a heavy clay soil. This is not a desirable container medium for any seed starting.....and not even recommended for more mature plants.

But they are not overly stressed just enough to make them grow but not too quickly but I'm expieranced. About planting lemon seeds I clay they aren't running yellow the trees aren't I think it slightly too dark

I think my trees are stressed but not enough to turn them yellow and when starting them in clay I'm expieranced there

" but I'm expieranced "

Apparently not to the degree you think you are, as every single one of your questions/comments on this thread are clearly pointing out.

But I've done that since I was a teenager maybe it is a much poorer Clay than I'm used to and the main light is a indoor LED light can that give some plant stress that can make it stressed. But not turning yellow but staying green
