cmventura, monsteras are generally easy in almost any soil as long as it drains reasonably well, I'd plant it and see how it goes. If you're concerned, you could always dig a big hole throwing the clay on a tarp, and then mixing half of that with some peat moss, perlite and pine bark mulch if that's available. Plant the monstera in the hole using the amended soil.

I've made a 1.5 foot high circular raised bed of edging stones and filled it with bark, peat moss and perlite mix for a rare philodendron in Cocoa Beach Florida where the soil is nothing but sand. The low stone planter adds a note of elegance to the garden.

If your deliciosa is the big species be sure to leave several feet of space all around, they can get massively big. If it has somewhere to climb, it will obviously take up less horizontal space. The one at my folk's place in Cocoa Beach has leaves 3 feet across and takes up a space at least 5 ft X 5 ft, but it's been there for a very long time. They are slow-growing, which is good considering their eventual size.

There are a couple of different variegates of the big species which are very attractive. One has flecks and smaller areas of white on leaves, the other is similar but has larger splashes and areas of white. The now-defunct nursery Asiatica sold the latter as 'Thai Constellation', but it was just a renaming for commercial benefit of the old M. deliciosa variegata.
