i have an old flower bed out in my back yard (south facing) its is squared in with some 2x4's or something i am not sure on the measurments but yall get what i mean. anyway i want to turn this into a bog. what is the best way to go about this? i thought of maybe digging about a foot of the dirt out and taking some plastic and putting it down then maybe put some perlite and sphag mix on top and then using live sphag for the top dressing and leaving it at that. i have never made a bog before but i thought in bama it should be easy for me to plant vfts sundews and sarrs out there and leave them there. if pics are needed i can take some and post but basically i just wanna know if my idea is ok or do i need to try something else.
