I need encouragement for I'm growing supermarket lemons from seed in clay soil in zone 6b

Try planting yuzu instead. You can find it in a Japanese market. I believe it is cold hard to zone 7, and so it would need some protection in zone 6.

there no Japanese market here in Ashland Kentucky

My yuzu tree generally makes fruit in the winter. Perhaps I can send you some fruit at that time. The seeds need to be planted right after the fruit is opened. Anyway, it does not have fruit on it at the moment.

The bridge between cincinnati and Kentuky is double decker with the trafic on the top deck leaving Cincinnati to Kentucky so that the kentuckians can throw their shoes down to the kentuckians entering Cincinnati. Cincinnati is marginaly if any better so No asian market in Cincy either

Okay

Howard,

Clay is usually a pretty good growth medium (as long as it doesn't dry into concrete. Usually very fertile, but slightly slower due to root growth rate. I have plenty of fruit trees that are in virginia clay (not true citrus due to hardiness zone limitations, though I am trying another calamsi).

Steve - Cincy has some asian markets. I visited a decent Chinese grocery there a few years ago when I was there. And Jungle Jim's has probably the best selection of all kinds of fruits and vegetables (including international varieties). That was a super fun place to visit.

this is all I could afford to put in my flowerpots I'm in zone 6b

Jungle jim is nice but very hard 55 mile round trip drive for me

Steve

I have a Yuzu. I'm in 7B zone. Nothing about that tree (granted mine is young) strikes me as particularly cold hardy. Although I heard that it was, which is why I bought one.

that maybe good Idea now push the genetics of it hard

I have grown several Yuzu seedlings outside in Olympia, WA, and they have survived through two winters, unprotected. It is in climate zone 8a. They seem to do pretty well. However, from what I observe, I get the feeling that they would not do so well if it were any colder, say zone 7, at least this far north with the shorter growing season.

Yuzu is pretty hardy compared to ordinary citrus, however, even Yuzu is unlikely to survive (outside through the winters) where HOWARD Martin lives. I did see a video where someone got a citrumelo seedling to survive in Tennessee, and that was climate zone 7.

but my zone is 6b

I have a Citrangequat seedling that survived 2 winters outdoors using passive protection only. a small wooden frame in garden, old window roof and plastic sheeting 1st time. 2nd time a frostcloth bag over the tree and frostcloth over the frame with an 18" dead air space (its just been up-potted and will come in until it has reached a branch diameter of 3/8" minimum or larger before I attempt again. Another season or even two. No heating. Expect to see total losses in whatever you grow from seed unless you are willing to protect. A seedling may be cold hardy when its an adult.....but it needs nurturing when young. I understand thats the idea but you need hundreds if not thousands of seedlings to do what you are doing - finding that one genetic freak. So you will be creating seedlings and then essentially killing them. Will they even in the ground or in pots over winter? No citrus will survive in a pot in zone 6B over the winter. But hey its like the lottery you never know....

If you can get seed you might find a freak Yuzu that hardier than its contemporaries

I only got lemon seedlings

ordinary lemons are one of the least cold hardy, out of the common citrus varieties

the actual order goes something like this, from more vulnerable to less vulnerable to cold:

lime, lemon, orange, grapefruit, white grapefruit & mandarins, Meyer lemon, Satsuma mandarin, kumquat

Although the differences in hardiness on this list is not as great as it is between regular citrus (in general) and cold hardy citrus.

Okay but I'm using what I have and I'm focused on doing so

I'm going to secede

I assume you mean succeed and not leave the Citrus Union

I'm in know citrus union

I got tough question . why didn't temperatures in the low 20's and upper teens kill my lemon seedlings this last spring

and my lemon seedlings are regular lemon

Do u have an answer

lemons tend to be more vigorous growing and have a remarkable ability to recover, so even if they are not very cold tolerant, their vigor and ability to regrow may compensate for that, if we are talking about actual survival.

I'm growing lemons in pots of clay soil. here in ashland,Kentucky in zone 6b

I have none of the varieties you mentioned here I have only the access to super market lemons and I'm thinking about about getting my lemons from more than one supermarket

Lars I don't want that type for it will defeat my purpose for the taste is reported to taste like a lemon and grapefruit cross and I don't want that I want true lemons and no other will do for me
