Well i am not positive what your problem is but perhaps you should cut back on the daily waterings. try every other day for a couple weeks and see if your scaveola looks worse or better. if that goes well then try every 2 days.... of course make an exception for unusually hot rainless weather (like we have been havig here in cinti lol) i know scaveola cant hack too much water.

i wanted to tell you the romantic legend of scaveola in case you didnt already know.

it seems that in ancient medevial times there was a pair of lovers. the man was preparing to go to sea and the lovers were having a tearful parting. he picked a flower bloom growing in the garden by them and gently tore it in two. he gave half the flower to his beloved and said he would keep the other half to remind him of her. and when he returned and they re-united the two halves of the flower to make it one flower again he would wed her.
Alas he never returned from his sea voyage and so the scaveloa remains a half a flower to this day.

how cool is that???

I have been told that container gardening often requires watering twice a day when it is really hot out (like now). The problem with watering is that as the water drains, so do the nutrients. You may need to use a slow-release fertilizer or put a liquid solution in your can once a week to keep the nutrients going. I gave up on hanging baskets because they are too labor intensive. I use windox box-type containers and although they have needed a daily watering, seem to be doing okay.
