The common belief is that orchids are very delicate and need special conditions to grow them successfully. NOTHING could be further from the truth. Actually most orchids, require very little in the way of care, in fact, they are better off with a little 'benign neglect.'
The Phalaenopsis (Moth Orchid) also known as the 'beginner orchid' is very easy to grow in the home. The other great thing about Phals is their long bloom time. It is not unusual for them to be in bloom for 3 to 6 months at a time. Once the plant reaches maturity at about 6 to 7 years, the plant almost never goes out of bloom.
Most orchids that are grown in the home need to be watered about every 7-10 days, or when the dirt turns light brown and the pot feels light when you lift it. The number of days in between waterings will vary depending on pot size, amount of media in the pot, root mass, and plant size.
Fertilizer should be applied every other time you water. We recommend a water soluble plant food that easily dissolves in water. If you have some house plant fertilizer on hand that you would like to use up, use it half strength.
Buds usually fall off for two reasons. First they will not complete their cycle if there are too many cloudy days in a row. The other reason is that the plant became dry. This is caused either by not giving the plant enough water, or there is excess air blowing directly on the buds.
Most orchid plants bloom in response to a change to their growing conditions. The bloom is what is needed to produce a seed pod. In order to accomplish this change the plants, will do two things. First we re-pot, and then we cool the plant down at night only. The night temperature should be about 63 degrees.
