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.

Great product
Size: 9.3" x 9.7" x 1.8"
I recently installed the BOSCH 6029C HEPA Cabin Air Filter, and the difference was noticeable right away. The air inside my car feels much cleaner and fresher, especially when driving in traffic or through areas with a lot of dust and pollution. It does a great job filtering out odors, pollen, and even fine particles—I’ve had fewer allergy issues since switching to this filter. Installation was straightforward and only took a few minutes, even without much mechanical experience. The build quality is solid, and it fits perfectly without any gaps or issues. Compared to standard cabin filters, this HEPA version is definitely a step up in terms of filtration performance. Overall, I’d highly recommend this to anyone looking to improve their in-car air quality. It’s a small upgrade that makes a big difference in comfort, especially for daily drivers or people sensitive to allergens.

Good quality!
Size: 9.3" x 9.7" x 1.8"
This cabin air filter is seriously a game-changer for my car's interior air quality. I was getting tired of that stale, dusty smell every time I turned on the AC. Swapping it out was surprisingly easy, and the difference was noticeable almost immediately. It really does trap all those tiny particles, like pollen and dust, that used to make my allergies flare up. Now, the air inside my vehicle feels so much fresher and cleaner. I've been recommending this brand to all my friends who are looking for a reliable filter. It's definitely worth the investment for a more comfortable driving experience. Seriously, if you're on the fence, just go for it!

Noticeable upgrade in air quality and a seamless installation
Size: 9.3" x 9.7" x 1.8"
I'm generally skeptical of the "HEPA" marketing for automotive filters, but after installing this in my Honda, the reduction in exterior odors—especially exhaust and pollen—is actually significant. The construction feels far more robust than the flimsy OEM paper filters I’ve used in the past; the pleats are dense and well-reinforced, which gives me more confidence in its filtration efficacy over a 12,000-mile interval. Installation was straightforward and took less than five minutes. It’s a precision fit with no gaps around the edges, ensuring that all intake air is actually being routed through the media rather than bypassing it. One thing to note is that you might notice a very slight decrease in max fan velocity due to the increased density of the HEPA material, but the tradeoff for cleaner air is well worth it in my opinion. If you live in an area with high pollution or suffer from seasonal allergies, this is a legitimate quality-of-life improvement for your daily commute.

Exact fit!
Size: 9.3" x 9.7" x 1.8"
Was a great replacement for OE on my 2012 Honda Accord. It was the exact same size as the previous filter and has no strange smells or odors. Very easy to install behind the glove box and looks great!
