Our story

When to Water LLC is a family company started by Carter Kline and his grandfather Michael Turner. Michael was looking at his hanging baskets one day after his wife died and he couldn't remember if he watered them or not, which planted the seed for his idea of an easy to read moisture indicator. He told Carter his idea and told him to turn it into a business. Several years later they turned it to a reality.
