After all the Christmas decorations are up, your living room and home may be looking a little bleak. If you miss the gorgeous greenery, designer Joanna Gaines shares some simple hacks to make your home bright and cheerful all year long!

Interior stylist Joanna Gaines, who stars in "Fixer Upper" with her husband Chip, recently posted this on Instagram with the caption, "I'm not a big fan of the green. But don't screw it up on the wall like I did. It's a bit much 😅"

Joanna then brings a large leafy tree branch into her cozy living room and places it inside a silver decorative vase. She then unfolds the branch before screwing it to the white wall behind her. This lovely decoration complements the earthy colors used in her living room. A brown leather sofa and chairs, a beige coffee table, a warm rug, and wooden beams. In addition, the wainscoted white walls provide the perfect neutral backdrop to accentuate the colors.

Best of all, this hack is a simple, easy, and inexpensive way to spruce up a room. Plus, it's the perfect way to bring the outdoors in.

"Being surrounded by nature is refreshing and invigorating," says Camilla Lesser, interior design expert at Essential Living. Therefore, as Joanna Gaines shares on her Instagram, incorporating natural elements into your home, such as plants, flowers, indoor trees, and ferns, can help improve your mood and lower stress levels.

January is a long, doldrums month, so doing this can help bring life back into your home again. Take Joanna's living room display of branches and vases as an example: the greenery brings life to an otherwise drab area and creates the illusion of a larger space. This is the perfect solution after the festivities, especially when you miss the decorations and the Christmas tree."

And even if you don't have access to giant tree branches, there are other ways to decorate with houseplants. Giant, lush floor plants, botanicals, and beautiful succulents not only bring the outdoors in, but can instantly transform a space.

The larger the plant, the greater the impact. Choose from tall plants, exotic palms, bird of paradise flowers, corn trees, olive trees, and more to add a touch of greenery. Like Joanna, you can add style by placing plants in beautiful decorative planters and pots, such as concrete, stone, resin, or woven baskets like this Artera Woven Seagrass Plant Basket ($16, Amazon).

Not only can they uplift your mood and bring the outdoors in, but they can also complement your home's decor by introducing new textures and pops of color.

Additionally, these seven indoor plants will make your home smell better, so it will always be fresh and inviting. However, if you suffer from allergies or are not equipped to take care of plants, you can invest in stunning faux plants that look as good as the real thing.
