Dry tips on leaves can mean a few different things. Most commonly, it is a sign of too little water. The leaves are the plant’s way of telling you that it is thirsty and needs more water. Another possibility is that the plant is getting too much sun. If the leaves are dry and crispy, it is likely that they are getting sunburned and need to be moved to a shadier spot. Lastly, dry tips can also be caused by a nutrient deficiency. If the leaves are dry and yellow, it could be a sign of a lack of nitrogen.
