At a fast guess (and a guess only), your soil retains too much water, your tree is indoors with too low of light level.

All ulmus are outdoors trees.

Here's hoping an more experienced hand, over rides my opinion.

Nebula,

Hello and welcome to the forum. First you should know that your tree is not a Zelkova it is a Chinese Elm. It is not uncommon that this species is misidentified, presumably to circumvent a restriction on the importation of Ulmus.


Here is a side by side of Zelkova and Chinese Elm.

The Zelkova is on the left. A US quarter Dollar is about 24MM

Chinese Elms also have some variation in leaf shape, here are some examples.

I agree with Toms likely Diagnosis regarding low light and poor drainage. I would not however place it outside just yet. Once the weather warms it should go outside if you have that option. I grow Chinese Elms and manage the, for the most part, as deciduous trees. This means allowing them a dormant period over the winter.

Chinese Elms have a wide distribution and are actually considered sub-tropical. Some do keep them indoors but this requires a greater effort on the part of the grower, far easier to keep them outside.

Here are two articles that should clear this up a little.
