Light

The Yucca plant is one garden and houseplant which will be quite happy with as much sun as you can give it. Indoors a South facing window would be the first choice. Whatever your light situation try to provide as much as possible

Watering

Water your Yucca liberally during warmer months of the year. Like all plants it’s impossible to give rigid watering intervals, but if conditions are exceptional (bright, warm etc) you could be looking to do this as frequently as once a week or more.

Humidity

Moderate humidity will be helpful, however misting of the leaves isn’t needed.
