Answer: Orchids are some of the most popular, and rewarding houseplants around! No wonder - their flowers are spectacular! The term "water soluble fertilizer" refers to a liquid or granular fertilizer that is diluted with water before use. On my orchids, I have great success by using a half-strength dilution of Miracle Gro for Orchids. Instead of a half-teaspoon of your fertilizer, dilute only a quarter teaspoon in a gallon of water and use this water to water your orchids during the spring and summer months. It doesn't sound like much fertilzer but you'll actually be supplying just the right amounts of nutrients to your plant on a constant basis. Your phalaenopsis orchid will like daytime temperatures of about 70F degrees in the summer, 60F in the winter, and a drop of ten degrees at night. Cool nights are important for flower bud formation. Give them bright light, 10-15 hours each day. Supplement with artificial light in the winter time. Keep the compost moist, but reduce the frequency of watering during the winter months. By moist we mean damp but not soggy wet. Mist the leaves occasionally. Keep them out of drafts and shade them from direct sunshine. Yellowing leaves can indicate over or under watering, and poor fertility. Hope this information is helpful!
