I’m not sure what kind of plant this is. When I got it, I replanted it and put stones at the bottom of the planter for filtration. I only water it once a week if I feel the soil is getting dry (I’ve heard its bad to water the plant more). I also added some micracle-gro houseplant food to the water at times. The leaves are getting brown spots with some of the tips turning yellow and then brown. Its in an area that does not get much natural light. So maybe that could be a problem? Also, I’m a little worried about the base of the tree. I’m not sure if it should be more of a green color? Any advice would help!!
Your plant is called a Dracaena Lemon Lime. The brown and yellow spots are being caused by too much plant food and too much water. Dracaenas need to dry out before they are watered. Since you moved your plant to a larger pot and it is not in great light, it may take two week until it needs water. Dracaenas do not need very much plant food. Feed your Dracaena Lemon Lime plant once or twice a year in the spring and summer with a basic houseplant food at 1/2 the recommended strength. Too much fertilizer causes the leaf tip burn your plant has. It will be a stalk plant eventually so the stem color is no problem.
