How do I decorate my new 12x12 americana greenhouse?

Are you referring to an actual greenhouse or a sun room? 12 x 12 isn't really big enough for furniture in a working greenhouse.

Here are lots of greenhouse decor ideas:

Hello Lynn,

Your best bet is to make a plan of the area and measure your plants etc. Cut out to rough size and place them on the plan. It will save an awful lot of backache. I do this with everything. It is fun to do and helps save time too........

Best wishes.

Also, assess your plants sun needs, for location in the greenhouse. Seating arrangements should be for comfort, too. Once you have everything in place, you may need to move things around or make better use of the space.

You will need furniture that can take the humidity and full sun if you are growing plants as well in the greenhouse. I would place my plants in the correct light for them and then buy outdoor furniture to use in this space.

I think that you would benefit by making 3 or 4 shelves to start seeds and to establish plants. You will also need a work table. If you don't have a shed, you may also need space to store bags of dirt, sand, manure, etc. And your tools. Good luck with this project. I would love to have a greenhouse.

HI Lynn - I love the idea of an Americana greenhouse! We made a flag decoration with our leftover pallet. Hope this helps with some inspiration. Hugs, Holly

Yes, it’s a greenhouse & the plants need to be placed based on their needs.

Furniture should take a backseat, pun intended.
