Yucca Plant Outdoors
Two weeks ago my yucca plants started losing their green color starting from top of leaf. The color (yellow) is progressing down every leaf. My other yucca plants are showing black spots. Are ants attracted to yucca plants?

It sounds like your yucca has a fungus. Treat the plant with fungicide. I like to use neem oil myself, as it is safe for people and pets and also will address any pest issues the plant may have. Here is more information on it: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
