My blue doesn't look that good right now. The plant is fine, but the flowers are smaller than they were earlier in the year and are less intense, more purple in the blue now. Do you think that's from the heat? It surely blooms a long time, maybe the flowers will get a bit bigger and bluer again in the cooler weather?

The other thing I thought of is that our soil is more acid, would it be beneficial to raise the soil pH?
