If they have sufficient room to grow and good growing conditions, they will offset.

In my experience, vertical planters require more maintenance than pots.

Depending on how large your vertical planter is, you may end up having to stage plants in terms of their water needs. Water will naturally drain out of the top portions and pool towards bottom portions, so you will need drain holes on one of the shallow sides to make a functional bottom. Stoloniferous plants, rhizomatous plants, and cremnophytes are all very good candidates for succulent vertical planters. Make sure to stage plants according to your light conditions as well. Sempervivums do best in full sun, whereas cremnophytes more shade.

Thanks for the tips!

Hoovb: Could you please elaborate more on the "more maintenance" part? Aside from potential drainage problem at the bottom of the frame, and the force of gravity making the soil mix drifting downward making plants on the top portion harder to anchor their roots, what additional care in these type of planters do you see?

Frame will have 6+ hours of sun, and a short width to prevent drastic movement of soil mix. It will also be firmly secured yet convenient for removal. Soil mix will comprise of 40-50% light-weighted perlite. If I do decide on using these vertical planters, I will most likely water them with the frame lying flat on the ground, then hang it back up afterward. Then again, sempervivum don't need much water so I don't need to water religiously.

I've always wondered how one of these might work. If you do it please post pictures! If love to see what you end up with!!!

1. If the plant has a smaller space in which to grow, it will outgrow its space faster and need transplanting more often. 2. Here verticals tend to dry out fast, so more frequent watering is required.

That is what I meant by more maintenance.

(In areas with summer humidity, plants are less likely to dry out as fast, so that may not be a problem for your area.)

Hoovb: ahhh i see. That was a very useful advice :D

Marquest: your projects are so creative and artistic!!! Are you planning to let the semps cover the entire body of the statues? btw, the stocking idea is very interesting. The fabric is stretchy so it can expand as the semp grow.

Deva: Absolutely! I will post some pics if I do decide to set it up.

Thank you for your input everyone!

Yes I plan to let the semps and sedum cover the body of the pictures.
