Fertilizing. Feed Phalaenopsis orchids with a balanced, water-soluble fertilizer diluted to half strength every 2-4 weeks during the growing season. Reduce feeding during winter.
Phalaenopsis orchids are relatively easy to care for but need stable conditions. They prefer indirect light and moderate humidity. Overwatering can cause root rot, so allow the potting medium to dry slightly between waterings. They bloom once or twice a year and can last several months.
