I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Both too much and not enough water can damage roots and result in problems in the topgrowth. The most likely cause of your plant's brown leaf tips is either dry conditions or burn from an excessive fertilizer application.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
