Beginner here – picked up these Alocasias from a UK big box store. Looking for ID help and care advice

Hi all,

Beginner houseplant keeper here. I recently picked up these Alocasias from a big-box garden centre in the UK and I’m hoping to get some advice before I repot them.

I’m not completely sure on the exact varieties, so ID help would also be appreciated if anyone recognises them.

I haven’t repotted them yet and they’re still in the nursery soil they came in. Before I start messing with them I wanted to ask people who know these plants better than I do.

A few questions:

• What soil or soilless mix do you find works best for Alocasias?

• Any watering tips to avoid root rot?

• Anything a beginner should definitely avoid doing with these?

They’re currently sitting in bright indirect light indoors skylight above and large glass sliding doors to the right, seem okay so far, but I’d love to give them the best start.

Appreciate any advice from the Alocasia experts here!
