Newly planted yuccas
The bottom leaves are turning brown..over or under watering? I've been watering every day since planting about a week ago. Thanks.
If these are new plantings, and the leaves are turning brown, it is most likely too much water for your drought tolerant plants.
Water with a slow trickle of water at the base of the plant to avoid fungus issues.
Water every two to three weeks in the first growing season, once a week if it is showing signs of water distress during a hot spell.
The plant should receive 1 to 2 gallons of water each watering.
