I have a good few small succulents that are growing well. They were initially planted in small seashells, then moved to small planter pots and now I’d like to have them merged to save space and have them visually nicer. This is how I’ve planted them now. A thin layer of pebbles at the bottom, then succulent soil and then the plants as you can see (I’m usually careful with watering and I only spray enough water to the soil avoiding the leaves):
In addition to the online suggestions, a friend –agricultural engineer– is suggesting that there’s too much space in the soil and since plants start with expanding the roots before working on the leaves/flowers, I should add more plants to make it tight and snug for the roots.
Ok, that makes sense but then there are articles like this one that suggest they shouldn’t be planted tightly or they’ll be growing slowly. So two opposing suggestions and I’m not sure which one to follow.
I have some other succulents that are doing well as they are but I wonder if I should repot any of them and/or add any more to this dish.
