help with tropaeolum tricolor - pests

I have a tropaeolum tricolor growing in my greenhouse.  It has yet to 
flower after a few years.  Two years ago, I had aphids and whiteflies in 
my greenhouse.  I sprayed it with either Safer soap or pyrethrin, I'm 
not sure which.  Anyway, that caused it to die back.  It's a very 
fragile little vine.

I am dealing with aphids again on my Moraeas, and I'm afraid they will 
attack the tropaeolum tricolor too.  Does anybody have any advice on 
what to do if they do?  The old "strong jet of water" advice would 
destroy this little vine too.

BTW, I empty and scour and disinfect my greenhouse every summer, and 
still the pests come back. :(

They can take much more cold this way and their leaves and spikes are better supported.  Good drainage is critical, and has been easier for me to ensure in the ground than in pots.

I then fill the pot the rest of the way with 100% ground bark to protect the bulbs from freezing. After blooming, the bark comes out. On a side note, 1 pot out of around 150 turned over on it's side for several months. When I found it, there were numerous babies around the mother bulb! So I had my helper lay down most of the pots. I should know next year if this was an anomality, or it speeds up offsets.
