Also, resist the need to water the plant every time you see it. That is the weakness of most plant lovers.

Lol, nice phrasing Chris. Yes, people seem to equate love with watering, and most plantings die of too much love.

Cold hardiness is the lowest temperature that plant can survive in. Bu if you keep succulent cold and wet (actually, most plants - not only succulents), that is usually a killer. Succulents grow in quite dry locations and rocky/grainy substrates in their natural habitat, and are programmed to survive it. They store lots of water in stems and leaves for 'later use'. If they are kept wet for long periods of time even in warm temps, their roots usually start rotting, and rot can spread into stems and leaves.

If it is raining so much in your location, I would suggest better than 50/50 perlite/soil mix. Using only ingredients that are of bigger size will give them much better drainage. Grit, perlite or pumice will work. If idea of no soil sounds strange, using some bark will work too - but it will hold some water, so adjust accordingly. As long as the particles are of bigger size (and relatively same) than soil, this kind of mix has much better drainage than using soil. Container should have plenty of drainage holes to allow any excess water to drain out.

Making mounds will also help drainage - they could be in ground or in container. If you are using soil as a considerable % of mix, pots should be, probably, protected from too much rain. Putting them under the roof. Or opening umbrella. Or putting a sheet of plastic over containers when it rains for extensive periods of time.

If I need to water succulents outdoors (most of the time they get water when it rains), I just take a garden hose and water as any other plants. Or, if I have plenty of rain water, I use a watering can.

Rina - I never thought about just covering then with plastic. I was worried about bringing them in and out. Thank You!

I'm not sure of the exact mix it's potted in. It's pretty loose, there's definitely some bark pieces, lots of perlite, and some soil. There seems to be more perlite and bark than soil.

That mix may work, but having more organics (soil and bark), it will retain water longer. So you need to make sure it won't get too soaked. (I use only grit and perlite, and small amount of turface for succulents).

I would also put the pot on some 'feet' - couple of bricks or you can buy pot feet in store. I would not use any saucer as it will just collect water.
