Be sure to check your potted plants after a heavy rainfall. Plants…any species that are not marginal (ie. those that prefer a spot by a pond or stream)…can develop crown rot if they are wallowing in a puddle of water in their pot.
Here in the Pacific Northwest, crown rot is one of the main causes of plant deaths through the fall and winter seasons.
Take away the trays under the pots to allow for free drainage. Or, if there are no trays underneath but the plant is still water-logged, place a couple of wood blocks or flat rocks underneath the pot to raise it up off the ground. If the plant is still swimming in water, knock it out of the pot, check the drainage hole is not plugged and re-pot the plant with up to one-third sand or small grit added to the new soil mix to increase the drainage.
