However, if you consider yourself lacking in a green thumb, it pays to take the time to learn a few plant care basics, like whether the plants you have chosen prefer sun or shade or how much and how often you should water them. Once you've got this foundation down, try adding in one (or more) of these 11 genius plant hacks to help keep your greenery looking lush.


1. Put a sponge at the bottom of the pot.

Every plant requires water in order to thrive, and most need it on a regular basis. Outdoor plants can rely on Mother Nature to provide irrigation, but indoor plants need your help. If you tend to forget to water on a consistent schedule, try a simple, inexpensive hack: a sponge. Sponges are made to soak up water, right? So, when you repot a plant, get an ordinary kitchen sponge. Set the sponge on the inside of the pot before you put in potting soil. It will absorb excess water and keep it right there in the bottom of the container, a little personal reservoir where thirsty roots can reach it.


2. Bury a water bottle in the soil.

For another easy houseplant watering hack, get your hands on a small plastic beverage bottle. Cut a small slit in the bottom of the bottle. Dig a hole in the soil of a large houseplant so that you can "plant" the bottle, standing upright. The top of the bottle should be at soil level. When you fill the bottle with water, it will seep slowly into the soil as the plant needs it.


3. Water with ice cubes.

Is there a hack for small plants that don't have room for a buried bottle? Of course, there is! Ice cubes. Scatter a few ice cubes over the soil surface, taking care to keep them away from the foliage. The ice melts slowly, allowing the soil to absorb water over time. This is especially useful for picky orchids that do best with very little water. One ice cube a week will do nicely for a small orchid.


4. Share your morning cup of coffee.

Can't start your day without that cup of coffee to get you going? Your houseplants can also benefit this. Though they don't crave energy from caffeine, the acid in the coffee can give your ferns, gardenias, and other acid-loving houseplants a boost. Simply thin out leftover coffee with water and then use the mixture to irrigate houseplants. Tea drinkers can use brewed tea to the same effect.


5. Use paper coffee filters and grinds.

Speaking of coffee, another houseplant hack makes use of paper coffee filters. When you are repotting a plant, line the bottom of the container with one or two of those thin filters. It's a very low-cost way to keep the dirt and compost in the plant pot while allowing excess water to drip through.


And here's another tip: Don't toss out those coffee grounds once the coffee is made in the morning. Instead, add them to an acid-loving plant's soil. The grounds will increase the acidity of the soil, as well as keep ants at bay.

6. Irrigate with leftover water from boiled eggs or veggies.

Coffee isn't the only breakfast item that works wonders for your plants. If you eat boiled eggs, save the egg water too. Let it cool to room temperature and save it for a nutrient-rich drink for your houseplants. This hack isn't limited to eggs, either. Whenever you boil a vegetable, the water contains nutrients that can serve as homemade fertilizer for your houseplants.


7. Dust those leaves.

So, you don't dust your house as often as you should, but nobody will judge you for that ... as long as you dust your plants. Those green leaves are beautiful and ornamental, yet their real function is to serve the plant. All plants use their leaves for photosynthesis, taking in carbon dioxide and turning it into energy with the help of sunlight and water. If they are clogged with dust, they "breathe" much less efficiently and can suffer. So every week or so, wipe off the foliage gently with a moist, clean cloth. You can also give your plant's leaves a spray of water mist for extra credit.

8. Shine the leaves with mayonnaise.

You put lotion on your face to keep it looking its best. Plants can look better too if you apply "leaf lotion" every month or so. While there may be expensive leaf creams at the garden store that promise to make your household foliage shine, here's a tried-and-true hack that costs a lot less: regular mayonnaise. Rub a bit of mayonnaise on each leaf with your fingers or clean cloth. They will look lush and shiny for weeks.

9. Turn the containers regularly.

Think about the last time you were at the beach sunning. First, you lay on your back, then flip to your stomach to get those warm rays on every part of your body. Your houseplant leaves would appreciate the same treatment. All of them need some sunlight to do their photosynthesis thing. If you turn the container from time to time, each side of every leaf has a chance to get some rays. This can be difficult to remember, so work the habit into your routine by giving the pot a quarter turn every time you water.

10. Play your plants music.

Research has shown that music can help plants grow because of the tune's sound wave vibrations. In particular, these green beauties seem to prefer classical music like that of Mozart. Online, you can even find specific playlists that were created just for plants.

11. Add kitty litter.

Certain plants can surprisingly benefit from having kitty litter added to the soil. That's because the litter retains water, preventing the plant from drying out, while helping with drainage and aeration. Species that could benefit from this interesting addition include aloe vera and donkey's tail succulents. The more you know!
