Meyer's Lemon can be grafted, but is frequently sold as rooted cuttings. Either way, it should flower and fruit by its second year.
Seedlings, like all citrus, take many years to mature. Usually, anything from 5 to 15 years, depending on growing conditions and not pruning incorrectly. I think you are in Canada, so it will be at the longer end of this time range.
If you are talking about a plant you've bought, they really should never be seedlings unless sold stating this. Most people are too impatient to wait fifteen years!

Thanks for answering my question. I had a tree at one time but it attracted spider mites so much I just could not keep it clean. Not only that but it was flowering in the fall and winter and I simply could not provide it with sufficient light at that time of year. Although the tree bore a good amount of fruit. So I got rid of it. But in the last several years I saw meyer lemon fruit in health food stores and this year I bought some to make marmalade and while slicing fruit I got a few seeds and thought of trying to start the plants from seed. However, fifteen years is a long time to wait. I love the flowers on meyer lemon very much.

Yugo, you'd be surprised by the number of people who grow citrus indoors and get trees to bloom and fruit, in cold, gray climate areas.
There's a Chinese Restaurant a few blocks from my house.. windows face north..Yet, they grow two citrus trees in this dim, north window, (Calamondin and some type of lemon) that flower and fruit every yr..
If you want a citrus that will flower/fruit within 2 yrs, buy a grafted tree.
Calamondin Oranges make fine marmalade/jelly, but orange not lemon.
BTW, do you have any relatives/friends who know the art of grafting? Maybe you can graft your own tree, the fruit production wait would take less time..Toni

hello, I live in z5 and my calamondin flowers and fruits every year. it is outside in full sun from may to about end of october, then inside for the winter. i usually throw away the fruit - i didn't know that people actually eat it. food for thought! thanks, Toni.

I think I can graft but what do you graft it on? As for the fruit from Meyer lemon I made marmalade when I had mine. This fruit is not as tart as from other lemons I know. Skin is very thin, aromatic and just lovely in my opinion. Now I buy the fruit in a health food store which prompted me to ask about growing it from seed. Anyway I made marmalade which I will be giving away as Christmas gifts. Citrus has a lot of pectin and it sets very well. I find Meyer lemons make an almost clear gel with shreds of skin suspended in it. It looks quite lovely in my opinion. Calamondin also makes good marmalade littlem. You should try it.

hello, yugoslava, would you share your marmalade recipe? thanks.

This is something I have read and ever since then have followed these instructions in making citrus marmalade. I use seville oranges or lemons, sometimes grapefruit. Wash fruit well, slice fruit very thinly. If there are seeds collect and put in cheese cloth. Measure chopped fruit and for every cup of fruit add 2 1/2 cups of water. Have all this in a large non reactive container in which mixture should sit for 24 hours. After that put pan on low heat so it does not boil it should barely simmer until the fruit pulp is completely soft when pressed between fingers. At that point discard cheesecloth with seeds in it. -When it reaches that stage it is ready to start making marmalade. Make marmalade in small batches. For every cup of fruit pulp I use 1/2 cup sugar. Some advise more sugar but this is what I use. Citrus has a lot of pectin, I think I mentioned that before, which means it can set a lot sooner . I use the old fashioned test to see if it is ready. Cool saucer from the freezer and spoon. Plop a small amount on the saucer, wait a little and if it's not runny it's ready. The marmalade sets further as it cools. I imagine you know about sterilizing jars and lids. I find if I cook it longer it becomes rubbery and kind of looses sparkle. I think that is all I have on this subject.

hello, Yugoslava, thanks. i am saving it for future reference.

Yugo,

Good health to you; I am 72 now. BTW, I don't think anyone answered your original question. You cannot grow Meyer lemon from seed; it has to be grafted or a rooted cutting. If you plant the seed, you will get some kind of citrus, most likely a lemon; but it will not be a Meyer.

My horticultural ambitions have somewhat subsided as I get older. Since that time, when I wrote about Meyer lemons, I've bought them, not grown them. Life changes, more weeds in my garden now.

Yugoslava, life most certainly changes. The weeds are a never ending battle but don't give in to them for giving in means giving up on life. Doesn't it?

Thank you for your marmalade recipe. I will try it.

Oh Vladimir that is so lovely. Never thought my recipe would be used after all this time. No, I'm not giving up on the garden or weeds. Pesky things that they are! When I think of it, weeds are not giving up on me.

johnmerr(11) I see you are in zone 11. It's southern US, where exactly? Did you have those awful storms?

I live in Guatemala, Central America.

Lucky man, you can grow anything. I was wandering where zone 11 might be. Recently, it was announced if nothing is done to prevent or slow down climate change, Canada, by the end of this century, will become tropical zone. At the end of last week, some group for preservation of wild life published an article and said contrary to public opinion, wild life in Canada is threatened to a greater degree than previously thought. Unless urgent measures are put in place more animals will be lost.

yugoslava So you have been around here for 10+ years

I was gonna say I don't remember, then I looked it up and I've been hanging around Garden Web Forum since 2001. Who would have thought! A long time. Since then many things have happened to me and the world. I'm alright. Can't say same for the world.

I received notification from Houzz, someone liked something I wrote here. People still come and read or write and ask. I stand by the recipe. It works. Wish other things stood the test of time as well! The world is in turmoil. It's a sunny day in Toronto, I opened the door and see a robin among the branches of small crab apple, the fruit stays on all winter.

Yugoslava, we appreciate your many posts and contributions!

I can only imagine what's in your garden. This morning was -6C. it will warm up later. Snowdrops are out, and my neighbor raked her lawn yesterday. She hated it because it's still cold. Even dogs are wearing coats! Short spring, even shorter summer.
