I got a small Euphorbia tirucalli (Pencil cactus) from my aunt, and i read online that i have to water it once a week or so. I am planning to place it at my balcony where the sunrises. Problem is, i live in a tropical country, will additional rainwater cause overwatering? assuming i have already watered it before the change in weather. Or should i place it indoors instead? i am also unsure if the temperature here is ideal? it ranges from 22-34°C (71-93F).
