My sympathy for your poor roses, Ron.

My tomatoes are not making flowers at the moment - it's been too warm!  But 
the fruits that are already set are happily ripening.  The peppers are, as 
you say, coming on like gangbusters.

I always get powdery mildew.  I had some cukes which produced very nicely 
for me for a while, and then  stopped - partly from neglect while I was 
busy with medical stuff, but partly because they had the powdery mildew.  I 
pulled them.   I have also pulled a squash - it produced very nicely and 
hadnt stopped producing delicious yellow squashes but it had the powdery 
mildew and was overgrowing its allotted space!  A third squash is mildly 
affected but continues to produce.

In answer to your question about the absence of moisture, "powdery mildew 
spores are carried by wind to new hosts. Although humidity requirements for 
germination vary, all powdery mildew species can germinate and infect in 
the absence of free water. In fact, spores of some powdery mildew fungi are 
killed and germination is inhibited by water on plant surfaces for extended 
periods."  This quote is from the Powdery Mildew article at

I'd love to get poinciana seeds!  Thanks.

I went to buy some camouflage trousers the other day but I couldn't find any.
