So to finish off this trilogy of posts, I’m going to talk about a few plants for the experts. I’m not going to go too in depth in this one – as I feel anyone ready to tackle these probably knows their stuff already!
Alocasia are a family of plants that are truly stunning, breathtaking and eye-catching. They are tropical, need warmth, humidity and moist soil. So can they be added to closed terrariums? Well, yes! You might find they do much better in a large closed terrarium (like a BioOrb) than outside, the only issue is that they grow so large!
Begonias are kind of like Marmite, you either love them or you hate them. I personally love them! But I am a sucker for silvery leaves and interesting leaf shapes. The issue I’ve come across using Begonias in closed terrariums is they don’t seem to like having wet leaves, and they can rot easily. They sure can be a statement centerpiece, but just be careful about misting them.
To finish off, I’m going to cover Carnivorous plants. Species such as Drosera, Venus Fly Trap, Nepenthes all require more in depth care than pretty much any other houseplant. They must be watered with rainwater, some species need to go dormant over winter and some species really should only be grown outside. So my advise for planting Carnivorous plants in a terrarium, is learn how to care for Carnivorous plants first.
