Question
Hi, I am writing because I consistantly kill orchids, and am not sure why. i do not over water, keep them in low light, try to follow all of the iinstructions and growing tips. I will buy I new one and it will do great for a month or so, then die bud by bud.  what is the secret? the one I have now has three buds left, how can i save it?

Answer
Lindsay, it sounds as if you are not actually kiiling the plant but are experiencing bud drop.  First, let me assume that you have phalaenopsis orchids-- the most common type.  They like warm temperatures (70 -80 degrees) and, probably, brighter light than you are providing.  Phalaenopsis like an east window where they can receive morning sunlight.  A phalaenopsis orchid can produce new buds on the same flower spike if it experiences buds drop.  You may be purchasing plants that are in a degraded potting mix which has caused root rot. Buy some fresh orchid potting mix and try repotting one or more of your plants.  Check the roots, after rinsing them off, before repotting.  If you see some collapsed roots, they should be removed as healthy roots are firm and turn green when wet.  If your plant's roots are in poor condition, that also can contribute to bud drop. This you can confirm when you examine the roots.  Remember that orchids can live for many years if cared for properly, and can rebloom even after losing some buds.
