It's hard to answer that kind of question especially without more
information, such as the size of your pot, type of soil and your
irrigation and fertilization methods. Is the larger plant shading the
smaller one to any extent? How much light are they getting? Do they
both appear healthy?
If the pot isn't too small and you provide adequate water, fertilizer
and light, the larger one probably isn't stunting the smaller one.
Did your seeds come from the same fruit? Are you sure your seedlings
came from two different seeds? Citrus often form apomictic embryos,
which are asexual embryos that are genetically identical to the parent
tree. They can also form regular embryos as the result of pollination
and fertilization. Some seeds are even polyembryonic, meaning they
contain both apomicitic embryos and a sexual embryo. The apomicitic
seedlings usually are more vigorous than the sexual seedling.
You could try pruning the top out of the larger one to get it to
branch. Just don't remove too many leaves . I have a forty-plus year
old potted grapefruit grown from a seed, and I regularly prune it back
a little. My main tree is over 6 feet tall and does have some stunted,
smaller seedlings at the edge of the pot. However, they were planted
later and definitely are shaded by the main tree, which explains their
