You may not be too far away from getting flowers! Maybe a couple more years? Most lemons from seed can take anywhere from 4 to 10 years depending on culture and growing season. You must not prune your tree, as that will keep it in a vegetative phase rather than encouraging the development of mature growth capable of blooming. Once blooms appear, they will likely appear near the top of the tree, where the foliage is first to 'mature'. But over the following years it should bloom further down. At that point you can probably trim it back a bit.

I would move your plant into a larger pot this summer. It needs to put on more growth and develop a larger root system.

What kind of lemon seed did you plant? There are a number of different lemons. Most can grow true-to-type, but Meyer Lemon will not.

I know this is off-topic, but, Dave, Meyer Lemon is an ancient cross. I would have thought that, by now, the genome would be stable. You say it is not. Why?

Janelle, good luck with that lemon, whatever it is. It is a beautiful plant.

Node count needs to be over 150-200 for good flowering.

CA Kate, I'm going by nearly everything I've read about Meyer. And by what Dr. Malcolm Manners wrote about it. I probably should have said, "It will likely not grow true-to-type".

Dave in NoVA is correct, Meyer lemons do not produce true from seed.

 They  say , that there is only  one variety or Meyer lemon   but Evey time, you plant the seeds from It is classified  as a new  variety   to me that me that means many varieties it

Howard you are correct. Their naves are MUT MEYER

CA Kate z9  so,,

  They are a true hybrid  and from their seeds what comes up  is always  considered a new variety  and seeds some times  never  Howard true because they are  the products of sexual reproduction so if you want the same as you had before  you might have graft  or roo or root a cutting

  I think I know how  the Cold  hardy lemon varieties develop it's from the bitter orange   that is in the  background genetics  there's  bit of    ponicrus  trifolata in the ancient back ground so when  the new cold  hardy variety develop  the   trifolata sides of them is coming back through  see they have the genetics  but not often triggered 

Howard 

Hoanetics for It but most of the time it's not triggered

  Lemons are  hybrid between a citron and  bitter orange that means some   citrus ponicrus trifolata genes are in the  back ground  but rarely triggered   so  the lemons have  the genetics to handle the cold  mostly citron side Is triggered and that is what is happening most of the time  why lemons usually can't handle the cold wheather.

Ponicrusguy6b4 52xx I figured out something  that maybe I wasn't supposed to about lemons. Lemons are a hybrid between bitter orange and citron   bitter orange is  ponicrus trifolata  most of the time the citron side comes out but rarely happens   the  bitter orange side is genetics triggered   that is why some lemon varieties c develop the ability to handle the co more cold  but but not most .

I thought lemons were a cross between a sour orange and a citron. I thought the Seville sour is often referred as a bitter orange. I am not sure where I saw that.

I guess I don't read enough. I thought an orange was an orange, a lemon a lemon and a grapefruit/pomella just that. I guess I was wrong.

Of course, then there are all the crosses. (sigh. oh dear, so complicated.)
