Thanks to all who replied, lots of good info. My concern when drilling was possibly snagging the wire screen, but if Wayne hasn't had a problem with this, that's good enough for me. I may try Guy's super glue and kicker method, as well. And Mel, I'm just as clumsy - you offer good solutions.
For the foam advocates out there, the advantages and disadvantages of terrain base construction methods have been discussed ad nauseum - that's not what this is about. I understand tree planting in foam is a breeze, but I'm using plaster over screen for my base.

doctorwayneWow! I didn't realise that it was so difficult to drill holes. Wayne
Well ya see Doc;
First you havta find the drill.
Then charge the battery.
Then select the correct bit.
Actually drilling the hole aint bad.
But then clean up the mess.
And then plant the tree.
Then put every thing away,or at least some place else
Just too darn stressful
Wow! I didn't realise that it was so difficult to drill holes.

From my experence, D-90 drys to be quite hard, I don't think pokeing will work. You will need to drill, or find a way to surface mount.
[ should have used foam]
I prefer medium thickness super glue and kicker. Dribble some glue on the base of the tree, hit it with kicker and your done. No drilling in plaster and no waiting for glue to dry. I have planted several hundred tree this way on my current layout.

I've used a scratch awl to poke holes in hard shell. I just kind of wiggle it in while pushing down.
A spike works too.

Thats why I like foam, just poke a hole.
Ed, I use natural plant cuttings for my tree trunks, and usually drill a suitably-sized hole in the plaster, and vacuum-up the plaster dust. I then put some white or yellow glue on the bottom of the trunk, then jam it into the hole. In some instances, the tree may need to be supported until the glue hardens.
The ones in the photo below are fill-ins, between the background trees formed from batt-type insulation, and foreground ones which will be added-in nearer the viewer. Some are installed in holes, while others are temporarily leaning against them, mainly to determine proper spacing, As you can see, the plaster dust from drilling has not yet been cleaned-up...
Here are a couple of pictures taken later, as the area was forested from back-to-front, to avoid damaging trees already installed...
...and the more-or-less "finished" scene...
I don't usually bother with making any representation of a root system for areas like this, but might do so for trees planted in more urban areas.
Most treed areas are not too near the edge of the layout (a too-near clothed wrist or elbow could quickly de-nude several trees in seconds when the fibre used to give some shape and body to the tree is contacted by cloth), so areas like the ones shown below are easiest to create...
I'm considering using the DuraBond 90 plaster over aluminum screen terrain modeling method as described on this forum by DoctorWayne. Wondering how best to plant trees in this hardshell terrain?
