is it Grafted? I dont see an obvious graft union. it looks like a seedling tree to me.

grafted trees can typically flower the first year.
seedlings can take many years, 5-12 is pretty common.

either way this one needs to just grow for many years before you would allow it to set fruit.

Also you should try and get it atleast 8 hours of light and be careful about watering. Just because the top of the soil is dry doesnt mean the rootzone is.

I have linked some very informative reading on container soils

Guerneys reply- bears fruit at 3 years old-is produced by cuttings. So fed up with this company. never again

There is nothing wrong with a potted Meyer's Lemon grown from a cutting. It is a common way of rapidly producing an ornamental plant that will fruit perfectly well just as quickly as a grafted plant.
If you require a highly productive tree for growing outside, then you should select a plant grafted on to a rootstock suitable for your local conditions.
However, supplying a well-grown cutting is not justification for criticising the producer. For many people's reqirements it is a good way to produce a suitable plant at reasonable cost.

Nothing wrong with a rooted cutting.

It looks like its gonna need to put on some bulk before you can expect fruit.

If it is a rooted cutting, it is not a dwarf Meyer.
