If you haven’t been to the houseplant section of your garden center for a while, then it’s time to pay it a visit. Growing houseplants is one of our favorite winter garden ideas. Pick out something you’ve never heard of before, and give it a new home on your windowsill.

“My houseplants spend the warmer months outdoors, but I bring them in during the cold months. They add a little green to winter. This year, I have some potted herbs I’m keeping indoors,” says Megan Long of Red Wing, Minnesota.

2. Plan Next Year’s Garden

As the snow piles up, start planning your gardens for the coming growing season. Think about new plants you would like to grow. “Lots of flower catalogs help me plan for an even better flower bed the coming year,” says Ginny Price of Taylors, South Carolina.

3. Grow Annuals Indoors

If you didn’t bring your own annuals indoors for winter, find a friend who did. Take a cutting from theirs and start some plants of your own. You have nothing to lose, and they just might make good houseplants until spring.

“I bring in my pots of geraniums, cut them back and set them on the windowsill in the basement. They get watered when I do laundry and seem to be quite happy,” says Mary Clark of Greensburg, Pennsylvania.

4. Conquer Kitchen Scraps

Have fun with your winter garden ideas and try to grow kitchen scraps. This is definitely experimental gardening at its finest. Try to get an avocado pit to sprout some roots, plant carrot tops, or put a pineapple top in a jar of water. It’s exciting to see what happens. Also don’t stop composting in winter.

“In winter, we compost our biodegradable matter. Coffee grounds, egg shells, vegetables and fruit all contribute to the pile. We aerate it with a pitch fork,” says Sue Steele of Essex, Maryland.

5. Plant A Few New Herbs

If you live in a milder growing zone, you might be able to keep growing food outside year-round. For best success, grow veggie plants that can handle colder weather.

“I plant a cover crop of cereal rye alongside broccoli and Brussels sprouts,” says Mike Buckler of Ringgold, Georgia.

Once they sprout and have grown an inch or two, it’s time to harvest. Or try a microgreen growing kit. And remember, those little sprouts pack a punch of nutrients.
