Hi Claire,
My nursery stock is all grown outside. The GH is used only for seed
starting, potting, rooting cuttings taken from the garden, over wintering
tender/marginal perennials (Brugmansia, Hibiscus, Tibouchina, Pennisetum
rubrum, etc.) and housing my tropical Begonia collection. Any new stock of
liners or bare roots is potted and put outside in the nursery right away.
Prior to using Marathon twice a year on the Begonias, mealy bugs were my
biggest GH problem. The year I tried to overwinter big baskets of Fuchsias
in the GH, it was whitefly (never again). Usually in early spring, just
before its warm enough to put the newly potted cuttings outside, I will have
an outbreak of aphids - but those are easily dispatched using the "2 finger
squish" method.
Finding this nematode on the old leaves of the anemones, is the first
insect problem I can remember having out there in 10+ years. There are
always weather related fungal problems during spring that disappears as the
weather warms and dries. Far and away my biggest problems are
1) Slugs and
2) the Marchantia (liverwort) that grows on the surface soil of the pots all
winter long. There is nothing to be done about it at this time except to
scrape it off by hand and trash it. This is very labor intensive and
annoying to say the least. Pots that sit on benches or gravel are
unaffected, pots that sit on soil all winter are VERY effected. If I had
the space, I would build a lot more shelves!
Sorry, that's probably a lot more than you every wanted to know about
nursery pests.

Marilyn, are you not worried when you add a new lot of plants to your
greenhouse especially if sales are very important to you? A lot of plants
can be "clean" for a short time and when the last treatment wears off
something new pops up. It always something.
