Moth orchids (phalaenopsis orchids) are terrific starter orchids for beginning gardeners, as they are low-maintenance, simple to grow and easy to care for during the winter months. Moth orchids are also long-lasting and can thrive in a vase or flower pot for up to three months. Maintaining your moth orchid during the winter is a simple process that does not require specialized skills as a gardener.
Place 2 cups of mulch around the sides of the ground where the moth orchid is growing. The mulch will help protect soil from drying, as moth orchids require humidity and moisture to stay alive.
Pour 1 cup of room temperature water into a watering can.
Sprinkle room temperature water from your watering can onto your moth orchid twice weekly.
Place a plastic trash bag as a cover on top of your moth orchid during winter nights when it is freezing. It is important that you protect your moth orchid from frost. If necessary, weigh down your trash bag with bricks or weights on the ground to ensure that the moth orchid is properly covered.
