How to Care for Growing Peace Lilies Outside
- 1). Plant peace lilies in soil with a pH between 5.6 and 6.5. If you do not know the pH of your soil, purchase a soil testing kit from a plant nursery. If your soil does not meet the pH requirements, amend with lime or peat moss.
- 2). Check that the planting location receives plenty of daytime sunshine. Peace lilies require at least 6 hours of sunlight per day when grown outdoors. Peace lilies planted in shaded areas may fail to bloom or thrive.
- 3). Provide the outdoor growing peace lilies with plenty of water. Peace lilies require at least an inch of water per week, when growing outdoors. Keep the soil moist, but not wet, at all times. Do not let the soil dry out in between waterings. Press your fingers into the soil before each watering. If the soil feels moist at a 1-inch depth, do not add more water.
- 4). Spread a 3-inch layer of mulch around peace lilies grown outside. Mulching with sawdust, straw or bark chips will help increase water retention and reduce weeds, which will compete with the peace lily for water. Mulch will also protect the roots of the peace lily from the heat of the sun or unexpected drops in temperature.
- 5). Feed peace lilies growing outdoors an all-purpose fertilizer. Check the package labeling for frequency and allocation amounts. Peace lily plants grown outdoors appreciate fertilizing in early spring and mid-summer.
