Spray with a low dose of an Imidacloprid or bifenthrin -based pesticide. But only spray when cool and not under full sun or hot grow lights. Do when cool or overcast. Works for all the bugs except mites. Rimmer > On Dec 14, 2018, at 1:30 PM, Sarah Hinckley <sarah-lists@suiattle.net> wrote: > > Hi, > > 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. :( > > thanks, > > Sarah > > > >> On 12/14/2018 8:05 AM, John Ignacio via pbs wrote: >> Here in south central Texas I find that almost all species and hybrids (except the epiphytes) are hardy in the ground and can be grown with their tops 3-4” below ground level.

We have not had a killing freeze yet, so the leaves are still green. This far south, I have them in some shade, which I believe helps with bloom longevity. The first killing freeze will naturally take care of leaves. >>> I had new bulbs in gallon pots 3 years ago which I had the mix just over 1/2 full with the nose of the bulb just below the top of the pot. 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.
