I've been working on being more green fingered myself too, I'm reading up on a lot of plants I have in the house and where they need to be placed for optimum growth. There's a really good app that help's identify what plant you have as well, then I google the aftercare for them. Both kids have plants in their room, your nephew has two succulents in dinosaur pots that we found in Sainsbury's the other week which we are teaching him to look after.
I would guess there's about 12 little babies.
You have your personal gardening tutor at home so you'll be fine!! I must ask KM to show me his plants next time I see him. But will he be more interested in the pots rather than the plants ? 😂
