Watering

Swamp loosestrife (Decodon verticillatus) prefers moist soil to thrive, so it needs regular watering to stay healthy. During the warmer months, this plant should be watered deeply once a week until the soil is evenly moist. If the soil remains dry for too long, the leaves will start to yellow and drop off. In the colder months, it should be watered less frequently, about every 2 to 3 weeks. Make sure to check the soil regularly and add more water when necessary to maintain the moisture level. Be careful not to overwater, as swamp loosestrife is susceptible to root rot.

Light

Swamp loosestrife (Decodon verticillatus) prefers full sun in order to thrive. During the summer months, the plant should receive 6-8 hours of direct sunlight. In the spring and fall, a minimum of 4-5 hours of sunlight per day is sufficient. During the winter months, the plants should receive at least 2 hours of bright, indirect sunlight per day, but no more than 5 hours of sunlight as too much direct sunlight can cause the leaves to dry and wither.
