Floating Marsh Marigold

Floating Marsh Marigold should be watered once a week during the growing season. During this time, use lukewarm water and provide enough moisture to wet the soil to a depth of 3 to 4 inches. Make sure to allow the top 1 to 2 inches of soil to dry before watering again. During the winter months, watering is not required as this plant goes dormant.

The Floating Marsh Marigold (Caltha natans) is a plant species that grows best in sunny locations that receive bright, direct sunlight for most of the day. This plant needs at least 6 to 8 hours of direct sunlight per day in order to stay healthy and bloom. During spring and summer, when the days are longer, the amount of sunlight the Floating Marsh Marigold needs increases and it can tolerate more sunlight. However, in winter, when the days are shorter, the plant should have slightly less sunlight exposure.

Floating Marsh Marigolds (Caltha natans) should be pruned just after flowering in late spring or early summer. The plant should not be pruned heavily, as the roots are rather fragile, and doing so could cause damage and reduce flowering in the following season. To maintain a healthy plant, remove dead or damaged leaves, weak or dead stems, and crossing or overly crowded stems during the pruning process. Generally, pruners should not remove more than 1/3 of the plant's stems.
