Gift or not, if the plant had a pest issue when you received it, I would ask for a replacement from the grower.
Cardamom prefers a rich, loamy soil that is slightly acidic with a pH of 6.1-6.6.

From winter through midsummer, feed your plant biweekly with fish emulsion. You can also feed your plant phosphorus and potassium as needed.

Cardamom requires a steady supply of moisture due to its’ tropical origins. It will not tolerate drought. Misting the plant and soil on a daily basis will help it thrive wonderfully.

Some of the websites I read mentioned that they often abused their cardamom plants such as forgetting to keep them damp, but that their cardamom continued to live. They seem to be quite hardy in this way, though I would still recommend giving them their few needs (correct temperatures and humid/moist conditions) in order to help the plant thrive.

Make sure the soil is well draining and that it is not soggy or too dry.
