Is it just top soil or does it have other soils in it chico? If it's just top soil I would be tempted to add about 1/3 the volume again of a lighter soil (peat moss, vermiculite mix). That way the soil is lighter and you won't have to worry about harming the tender shoots. Even if some broke off I'm sure they would grow again. If I remember correctly most of your plants are very resilient anyway.
Assumptions do nothing but make an ass out of u and me.
We can stick our heads in the sand for only so long before it starts choking us. Face it folks. The pet population is bad ALL OVER THE WORLD!
