Re[2]: buddleia
Good point Deborah, it might be too much water. I have mostly sandy
soil so I don't tend to worry about poor drainage, but the area where
the buddlea is (was) has considerable build up of leaf litter, so it
probably holds water very well. I have the entire area on automatic
drip irrigation so I don't tend to pay that much attention to how wet
the soil is each time the water goes on ...
The anisodontea, on the other hand, was in very well draining (sand
and decomposed granite) soil with no leaf litter build up and
scorching sun. That said, it was also on drip, going at about the
same rate as the area where the buddlea is this year.
I'll have to experiment a bit with this one...
Thanks!
