Default This Summer's observations...

Diana,

Bugs must be a regional thing. In my 15 years of orchid growing I don't
think I've ever seen thripes but I hear about people complaining about them
all the time.

For Spidermites I keep the humidity so high in the greenhouse that they
haven't been a problem for me on orchids but every year I have a trouble
with them on a calomodin orange tree that I've had for 40 years. About
Christmas time after being in the house for 2 months I can depend on them
showing up on that. A spray of an indoor plant insecticide usually gets rid
of them. Sometimes I have to come back a couple of weeks later for another
hit.

I understand the isolated bug problem. It only takes a few bugs on a
favorite plant to spoil your day. The damage from the scale lives on a leaf
forever. I have a couple of Catts that look like they had a bad case of
chicken pox with the scars of scale. Luckily theres a new growth to make
it look fresh and new.

Good growing,
Gene

Gene,

I completely agree about some plants being magnets for certain

infestations.
I can't remember seeing mealies on a Catt, but I certainly have seen them

on
Phals. I've never found them to be awfully hard to control, thankfully.

Scale, on the other hand, is tougher for me. I have an Angraecum,

Longiscott
'Lea', which must have a "bite me" sign out. Yet nothing near it was
affected, though I treated everything nearby anyway. The Angraecum is now
healthy and in spike. What I find hardest to control is thrips, which

adore
our Vandas. I think I've scared them away, happily.

For the first time ever, I had an infestation of spider mites on the Phals
earlier this year. The little sob's don't announce their presence until
they've done some damage, but we got rid of them with soap and veggie oil.
All gone.

All that makes it sound as if we've had big bug problems this year, but

that
is not correct. There have been a few isolated incidents.

A while back, I posted a query about orchids blooming way out of season.
Now, that is still a mystery to me.
