Cattleya rooting- input needed!!!

[InspirChid1712]

Hi Everybody!

Alot of my cattleyas have lost roots since our cold winter and VERY rainy spring/early summer (and SLUGS... those little demons!). This has been a very unusual season here in North Carolina. The tried-and-true plants look good as always, but a few that normally do well seem to be really set back this year. Alot have very few, if any, functional roots. They have new growths that are half matured, but what can i do to get some actual roots growing? Should I keep them really dry to get them to search for water? Its getting late in the season and I really want to get some good roots going before winter so I don't observe slow mass suicide in my plant windows. What should I do?!?!?!?!?!?!?!
