Well, my DH is in the process of making me a new potting bench. The old one just fell apart. My "must haves" were:

It has to be movable
Easy to clean
A hole or slot in the table top to sweep dirt into. I have a tub underneath to catch the excess dirt.
A smaller shelf on top to put waiting pots, trowels, etc.

Old barn wood would make a great potting bench. We haven't "blinged" mine yet, so it's still pretty plain. It's also made out of vinyl and "fake" wood so it will never rot. I'll post a picture when it's finished.

Good luck with yours!

Marlene, thanks for your response! We are perusing the area for artsy fartsy stuff, but want to know the real "needs" to make a potting bench real! Nancy

The neighbors picket fence fell over! I've been watching to see if they want to get rid of it! LOL I might leave a note! Nancy

Always worth asking! We've found lots of stuff that way~

For me it would have to be able to be left outside in the winter. I might have to make myself one out of cement blocks.

I have one that my dad made for my mother from old weathered cedar siding. I keep it inside my potting shed because to leave it outside would ruin it in just a few years. I also made one from an old buffet. It has two drawers in the middle and cubbies on either end. I added a fence on the back for hooks and hung an old mailbox to hold gloves. I covered the top work surface with some sheet copper to protect the wood from moisture. I'm going to moisture proof the top drawer to hold extra potting mix. I'll probably sell the one I made and keep the one that was my mothers.

Dh built mine years ago. It isn't fancy but has everything I wanted. It has a narrow shelf on top for extra pots etc, a 2 foot by 4 foot working area but the real kicker is a hole cut to fit an old metal refrigerator vegetable drawer (crisper?). I can put my potting soil in it, moisten it and scoop the soil into the pots. There's an 18 inch deep shelf under it to hold larger pots, extra soil, fertilizers etc. I've had it over ten years but it is in the green house so it is protected.
