Grow Nolina palm in bright light for best growth, but it tolerates medium- and low-light spots, as well. Because it stores water in its thick trunk, ponytail palm can survive extended periods with no water -- making it the perfect houseplant if you tend to travel a lot or are a forgetful waterer. That said, this houseplant tree will grow best if watered regularly -- when the top inch or so of the potting mix starts to dry. Fertilize ponytail palm a couple of times a year in spring and summer. You can use any fertilizer labeled for use on houseplants; just be sure to follow the directions on the product packaging. If you wish to fertilize your plant more frequently, you can -- it will respond by growing faster. If leaf tips turn brown, simply clip off the brown parts with a sharp scissors to keep the plant from looking unsightly. Nolina palm is not intended for human or animal consumption.
