watering

Water the yellow adder's tongue every 4-5 days. Water the plant sufficiently to ensure the soil is moist but not soggy. Soak the soil initially until water starts to drain out of the bottom of the pot. Stop watering and let the soil dry slightly between waterings. The yellow adder's tongue is native to moist, woodland areas, so ensure the plant is not left without water for an extended period of time.

sunlight

Yellow adder's tongue (Erythronium americanum) does best when grown in partial shade. This means that while it should be exposed to some direct sunlight, the amount should be limited. It should receive only 1-3 hours of direct sun per day. The best time of day for the sunlight to hit the plant is in the morning, around 10 am, as this will help the leaves dry off. During the summer, it should be moved to a shady area or provided with some shade from a garden cloth. This will help protect the foliage from being burned by the hot afternoon sun.

pruning

Yellow adder's tongue, or Erythronium americanum, should be pruned once a year in late winter or early spring, before the new foliage begins to grow. It is important to prune only after the foliage has fully dried out. Remove any dead and damaged leaves to promote healthy growth and improve the overall appearance of the plant. Remove any old, diseased, or non-vigorous foliage that has not produced new growth in the last year. Prune lightly, removing no more than 10 to 20 percent of the foliage at any 1 time.
