My yucca plant has started to get yellowing leaves, drooping, and not as green as it used to be. What can I do to revive this plants? Thank you for your advice.
This appears to be what is known as a variegated corn palm. An indoor variety of yucca. That streak down the center is called variegation. It is normal on that variety. Now, I do notice the tips are burning a little. I would only seldomly feed this as they are light feeders. Make sure the soil gets moist, not wet, and only dries out the top two inches between waterings. You should apply dolomitic lime every 6 months to keep the pH stable.
