I got this Incrassata 'Moonshadow' just over 2 weeks ago, it's in a 3" pot, and the soil has just now become dry almost half an inch down. I'm concerned about winter. Will it stay wet too long when the weather really cools? As you can see, there isn't a huge amount of perlite in there. My last Moonshadow died after 5 months (no idea why) and I want to make this one happy. Would you repot now, or wait until spring?
