I got this for free because most of the leaves were brown/yellow and crispy. The only identification given is "tropical plant". I trimmed it up, but I would like to know what plant it is and care requirements so it has a chance to survive.

Dracaena janet craig compacta I believes

Your Compacta appears to be in very good condition so you have done a good job with your trimming.

This particular Dracaena is very prone to brown leaf tipping if anything is out of line. Typically, it occurs primarily on the older lower leaves.

Keep it close to a moderately sunny window but beyond the direct rays of the sun. Keep it in its nursery pot indefinitely. Water it thoroughly as soon as the top surface of the soil feels dry to the touch.

Here are the things that will exacerbate leaf tipping: soil getting too dry; using hard water; excessive fertilizing; too little light; direct sunlight; and temperature extremes.

Awesome. Thanks for all the information!!
