I Have Many Yucca Plants in Backyard Pots
All of a sudden several of them have started to lose leaves and have turned black in the center. It has been real hot and I have been watering them daily but since this started I have slowed down on the watering. Help, because I don't want to lose them! All of them have several groups in them and not all are doing this. . . . Thanks.
