Please Identify this Indoor Plant

My sister asked me to identify this plant and I am not a houseplant expert. Can you identify this houseplant for her and tell her why leaves are turning brown.
Thanks
Brenda

 

Hi Brenda,

 

Long, narrow, green and white striped leaves on a Dracaena warnekii
Dracaena Warnekii
Striped Dracaena

 

The plant is called a Dracaena Warnekii. All dracaenas are very sensitive to fluorine and chlorine. If her household water is heavily chlorinated or contains a great deal of fluoride, allow it to sit out over night before using it; use water from an outside hose; use rain water or distilled water. Never use water that has passed through a water softener. It is too salty and can damage the leaves.

Too much plant food can also cause brown leaf tips. Dracaena plants are very light feeders. Feed monthly in the spring and summer with a balanced liquid fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small. diluted to 1/2 the recommended strength. It’s not necessary to feed dracaenas in the fall or winter..
