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.

Beautiful for decor, not great for anything with heft.

They are easy to install and exactly as pictured. I find them to be lovely and uniform, and they can't with proper instructions and even extra pieces. I took away a star because they are described as "heavy duty" use, but the dowels used to mount the shelves are flimsy. Mine are mounted on combo of studs and drywall, the plates are secure and not going anywhere. The problem is the dowels themselves that fit into the corresponding holes of the shelf: they bend easily. I put three books and bookends on one shelf and watched it tip down. I did attach the bottom screws into the dowels I secure the shelf to the mounting brackets, but that's not going to save any items from sliding off as it bends down over time. I pulled the books immediately and decided to use these for decor only rather than any practical use. The stock photo suggesting lining these shelves with glass jars filled with flour, rice, and lentils is a terrible idea.

Perfect for what I need.
Color: Rustic Brown, Size: 40"W x 12"D, 2Packs
These floating shelves are perfect for the price. There a number of things that I think other reviewers just get wrong. Here are some thoughts and tips: 1) QUALITY: Yes, these are not super high quality. They are not real wood and they are hollow. BUT, real wood is more expensive. You're getting two shelves for about $100. if you want higher quality then you'll have to spend more. For me, i wanted something that looked good and could store knick-knacks. And these certainly fit the bill. It amazes me how people who spend the least always demand the most. 2) STRENGTH: Some people have said these aren't very strong and sag at the ends. These are floating shelves and the ones I got were 12 inches deep. That is a significant amount of leverage on the mounting hardware. it's not that the shelves or the mounts are cheap; it's that physics simply makes floating shelves like this inherently less stable and unable to hold significant weight. SOLUTION: You have a number of things here that will add to stability. This company provides a generous amount of screws and anchors. USE THEM. If the shelf is long enough, make sure you catch at least two studs to anchor into. There are a decent number of screw eyelets in the mount and they are wide, meaning you have room to play. Finding a stud to mount into should not be too challenging. So that's two screws right there. As for the other eyelets, you will be forced to use wall anchors. Wall anchors are another one of those things that are simply inherently not that strong. They are not meant to take much of a load. But the more you can use, the better. Just know that those can provide some stability but they really don't add a tremendous amount of added strength. Additionally: if you have a 3d printer or know someone who does, print a support. I was able to find some really discreet supports to print that do not detract from the floating nature of these shelves. If you mount them on one or two sides, you'll have far less "sagging". The additional supports will add significant strength and stability. Given the magic of 3d printing filament, you can literally get any color you need so that you can blend seamlessly into the wall (or just print whatever color and then paint it). If you can use PETG or ASA, or some other strong filament, then you'll be golden. PLA can definitely be used, but just be familiar with the strength limitations of PLA. All in all, these do the job. They are attractive and support just enough weight to serve their purpose.
