Both of those plants grow in full sun & that's in south FL in the US. I would say your plants are suffering from not enough light. Also both of them tend to like soil more on the acid side & very well draining. These things grow in sand in FL & nothing lasts long in sand - nothing meaning water or nutrients. They can take down to 40 degrees fahrenheit. I say put them both outdoors in the sun as long as it doesn't get below 40 degrees. When you have to bring them in because of the cold, then make sure they get the most sunlight you can give them and make sure not to overwater -- well drained soil is a key.
