Flushed pot on front patio

On 10/14/18 we did a deep soak and repeated flushes with water to the potted plant on the front patio that I mentioned in the last journal.  It has been struggling.  A kind and helpful blog reader (thank you!) suggested flushing the pot as salts from regular watering may accumulate.  Why didn't I think of that!?  I use Reverse Osmosis water for exactly this reason on our houseplants, but I do not do this on the outside pots.  This is the only one on a hard surface and, therefore, in a saucer.  Fingers crossed... let's hope this helps.
