I'm surprised D. adelae lasted that long! :-)
Don't try D. adelae, prolifera, or schizandra outside in AZ. They're all
delicate shade-lovers. I had good luck with D. aliciae, capillaris,
intermedia, natalensis, spathulata, and others of that design.

Well, I've forgotten exactly what I was using. For the above I mostly
used a sand & peat mix (remeber these were extras I stuffed into any
kind of available mix). For the pygmies and tubers I used more
sand and perhaps some vermiculite along with peat. I also put these
plants in tall pots made of plastic drinking cups. I supposed that these
didn't want to be as wet as the temperate and tropical Drosera, and also
I supposed the tuberous ones wanted deep run for their seasonal tuber
production. The tall pots and sandy soil may have left them too dry,
though obviously they weren't really dry or they wouldn't have lived
at all.
I'd recommend keeping the D. peltata inside while you experiment with
weedier common species like D. spathulata.
