Guppyromz, welcome to Tropical Fish Keeping forum.
I agree with previous members, to remove the wrapping/pot/wool from the roots. Another point is the plant species; some stores regrettably sell terrestrial plants as aquarium plants and these often rot quickly or eventually. If you could post a photo of the plant, it may help us too.
A third point is nutrients; plants need 17 nutrients, some of which will be readily available in a tank with fish and regular water changes, some may have to be added; are you using any fertilizer, and if so, which?
Last, light, the most important. What is the type of light (be specific) and how long is it on each day? And what is the tank size, as this relates to the light.
