Hello there MindiHammerstone! We are in same location and I also tried Caladiums before.
Caladiums enjoy the warm to hot temps but not our scorching Central Valley heat. If you intend to bring it outdoors, position it in a bright light but shady area. The leaves will easily burn when it gets our very dry summer heat. I used to water daily my Caladiums when our weather shifts to the dry and warm to hot mode. As it stands right now, it is okay to put it out, overnight temps are in the 50F's and the daytime highs are slowly going up. So far our daytime highs is still gentle though this weekend it is still dicey as they are predicting the 90F's. All the more when our daytime highs starts hitting super dry 100F and higher, you got to step up watering.
During late Fall to winter, when our overnight temps starts to go cooler than 50F, pull that plant indoors. Typically it will just go dormant during the cold season, and will wake up again in mid to late Spring.
But I do not have them anymore, I find it too hard to sustain its humidity needs. I guess it lasted for about 2 years before I totally gave up. I also find it is so slow to wake up from its winter slumber, really waits to feel the high 80F's to low 90F's before it will show signs of emerging leaf growth. I do not use anymore skewers when our weather goes dry here in mid Spring. Our humidity is just so dismally low, you will need to water everyday, it is such a thirsty plant due to our lackluster humidity that often settles just in the 40% and lower range. And with about 6 months of zero rainfall, it will really need stepped up daily watering.
You can certainly try to grow them indoors with good access to bright light by an east facing window or a curtain protected south/west facing window or maybe closer to your house under an awning, but avoid getting the scorching sun.
Here are some old file photos taken late Sept 2016:
The plant will naturally lose its leaves towards the end of Fall, so I just pull back the container indoors so it can rest during winter. I find they are less vibrant the following year, so eventually I just let the plant go. But it sure was a nice experience growing them, love its colorful and fancy leaves!
