Hi. I got an Anthurium gemini several weeks ago. When I got it, it had several blooms and 2 buds. The buds have since grown into flowers; however, the stems of the other flowers are turning yellow and the tips of several of the spadix (long yellow part of the flower) are turning brown. Is this normal or am I doing something to cause the flowers to die off?

Also, is Pro-Mix a good soil to use with this plant?

Please help! Any info you cound give me would be greatly appreciated!
