I've been reading a while that in cultivation, many dewy pines die after flowering. Why is this? Is monocarpy common in this species in the wild as well? The two main reasons I've heard of is that the plant simply exhausts itself while flowering and setting seed, or that watering it after it has flowered causes the roots to rot. A few days ago I saw many mature dewy pines that were flowering or had just finished flowering, and some of them were dead or dying while others looked completely healthy. They were all about the same size and grown in identical conditions. On some of the plants, one of the branches would die while the others remained alive.
Is there any way to prevent this from happening in cultivation? My plant has been thriving since I got it, and I would hate for it to put out a flower stalk next spring and then have it keel over. Can the flowers be cut off early on or does this harm the plant? Does making sure it gets enough insects during flowering increase its chances of surviving?
