Indoors, grow asparagus fern in a medium to bright spot. It's best to shield asparagus from a lot of direct sun. Water asparagus fern regularly; the leaves will turn brown and crispy if it doesn't receive enough water. Outdoors, asparagus fern does well in shade or part shade. It can take full sun if it stays relatively moist. Regular watering is important, especially if you grow asparagus fern in hanging baskets. Asparagus fern is not intended for consumption by humans or animals.
