How do you care for a hoya plant?

You’re looking to start a hoya collection and you want to make sure that your plants are happy and healthy.

But you’ve heard that caring for hoya plants is hard.

What type of soil do hoya plants prefer?  What temperature range do they need to survive and thrive?  How damp shold the soil be?  Do hoyas prefer small pots or large pots?

There are around 900 known species, cultivars, and hybrids of Hoya, so naturally not all Hoyas thrive under the same conditions and many of them have different traits and care requirements.
