Trying to email you, but your emails keep coming back to me as undeliverable. Do you have another email address? Annette

Depends on if it has a solid bottom or not. If it has a solid bottom - like a concrete planter with a concrete base - then it is just a large container and needs to be filled with a soil-less container potting mix. And we hope it has some sort of drain holes :-) If it is only solid sides but a bottom open to the underlying soil/ground, then it is considered just the same as a raised bed and any sort of enriched soil product (garden planting mix, topsoil and compost, etc.) will work fine. Look for somewhere that sells bulk soil products. That planter will hold about 3 3/4 cubic yards of material and you could go broke trying to fill it with bagged product!

recently bought??? .. from a greenhouse ... and set in full blinding sun.. without hardening them off ...???? flowers a very short lived ... i like the word ephemeral ... and extremely easily damages ... either by sun ... or water on them ... the plants otherwise look fine ... as much as i can see ... just take some scissors and snip off the damaged flowers.. maybe you will get a reflush of flower ... ken

As long as there is food (rodents, chicks, eggs) you will have snakes. If you let the ratsnake live, it leaves less food available for venomous species.
