Feed Your Entire Indoor Plant Jungle with One Fertilizer

Balanced 9-3-6 Formula Nourishes Foliage, Roots, and Flowers for Healthy Growth

Simplify plant care with our Liquid Fertilizer for Indoor Plants. With a 9-3-6 NPK ratio and added micronutrients, this all-in-one plant food keeps every houseplant—leafy greens, flowering favorites, and everything in between—healthy, vibrant, and growing strong.

If you love houseplants, you probably have more than one! When your home looks like a lush jungle of greenery, keeping track of every plant’s needs can be difficult. That’s why you need one perfectly balanced fertilizer to make every plant happy and keep your to-do list simple!

Our liquid indoor plant food has a 9-3-6 NPK ratio. The high nitrogen promotes healthy, green foliage while the other nutrients encourage roots to grow strong and flowering plants to produce buds. This fertilizer is also a great source of other nutrients your plants need to be healthy. It has calcium, magnesium, sulfur, copper, iron, manganese, and zinc, all of which will promote your plants’ overall growth and health.

This indoor plant food can be prepared the same way for all your indoor plants, but the frequency you need to apply it will vary for each plant. You’ll need to keep track of what each plant needs, but you’ll only have to prepare one fertilizer for all of them.

How to Use Liquid Fertilizer for Indoor Plants

You can prepare a large portion of liquid plant food at once if you need to feed many plants. Mix one teaspoon of fertilizer per one gallon of water. If you have any leftovers, you can store them in a container with a lid and keep them for up to six months.

To feed your plants, water them according to your regular watering schedule but occasionally replace the water with the fertilizer based on each plant’s needs.

How Often to Fertilize Indoor Plants

While this plant food is suitable for all plants, the frequency each plant will need it every month will vary depending on the plant.

Fast-growing plants usually need fertilizer every 2-3 weeks in spring and summer and less often in the winter. Slow or moderate-growing plants usually only need fertilizer once or twice every month in spring and summer and may not need it at all during the winter. 

You can determine if your plants are getting enough nutrients based on how much you water them. Different plants will have different signs of not receiving enough water, but the most common signs are wilting, dropping leaves, or the development of crunchy brown leaves. Dehydration is challenging to reverse, but once you give your plants enough water, it will promote new growth. Brown leaves won’t be able to turn green again, so you’ll need to remove those.

A common sign of too much water is yellowing leaves. Leaves will start to turn yellow on the tips and edges until the entire leaf is yellow. Some plants may wilt or drop leaves if they receive too much water. The best way to tell if your plant is overwatered is to check the soil. If it’s wet, you may be overwatering it, or there may not be drainage holes in the container.

Fit my 2018 CRV 1.5 turbo
I’m not a car expert, my maintenance expertise involves air in the tires, adding oil and washer fluid, and these filters. Found a video to show me how, it was easy. These fit my car, and I don’t see any difference in these and the filters they replaced, except of course, these are cleaner. Very happy.

Good Fit for 2025 Honda CR-V EX-L
Very happy with purchase. Fit like a champ. Be prepared to work to change the engine air filter. It is more about Honda's design the the filter itself.

Very durable and quality produced.
These filters seem very durable and quality made. The air filter looks exactly and feels exactly the same on the factory filter and very easy to replace. The cabin filter was also very easy to replace. This cabin filter feels a lot heavier and higher quality than the factory OEM. Be sure the rigid sides of the filter will fit on the left and right side when installing. If you try to install the filter with the information written on it facing out, then the cover will not fit properly. When the filter is in place correctly, the cover will be easy to put back in place. Both filters seem very durable and quality made.

Perfect fit
I started changing my own filters about 10 years ago when I realized how much I could save, and how incredibly UNcomplicated it is. Anyone can find super easy instruction and videos on YouTube. Obviously some cars differ, but I've yet to find one that isn't as easy as replacing batteries in a remote. These filters are the exactly same size, and are made from good quality materials that are equally as good as the OEM filters I pulled out of my 2025 Honda CRV Gas vehicle. They're wrapped in plastic, so they're as clean as an be when you get them. It literally takes less than 10 minutes to switch out these filters, so you're saving a bundle by doing it yourself! Compared to having a dealer do it, this is a super great value, as they not only charge for labor, they probably charge twice as much for the filters themselves. So far, I have had any issues with air flow, and have not gotten any weird warning signs, so clearly they're functioning in the same way the dealers parts do. I mean, they look and act just like the parts already in the vehicle, so I don't expect any issues.

Easy DIY replacement
This engine and cabin air filter kit was an easy and worthwhile replacement for my vehicle. Both filters fit exactly as expected and matched the originals in size and shape. Installation was quick and straightforward. The cabin air filter slid right into place, and the engine air filter seated properly with no gaps or bending. Airflow immediately felt improved, and there were no warning lights or fitment issues after installation. The filters appear well made and sturdy, not flimsy or overly thin. It’s convenient having both the engine and cabin filters included in one kit instead of purchasing them separately, especially for routine maintenance. If you drive a compatible CR-V or Civic and want a simple, cost effective DIY replacement, this kit does the job well and saves time.
