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.

Not really medium, but a quality pillow nonetheless
Size: Standard (Mid Loft), Number of Items: 1
It is absolutely the case that with this type of product, most people who review it don't actually know what they're talking about. Latex foam pillows are not like any other kind of pillow, so your expectations have to be completely different. It's not about thickness, height, or anything else but comfort. Comfort in this case comes from you choosing the correct level of FIRMNESS. Since each company has their own idea of what constitutes each level, the difficulty is figuring out which one is going to work for you. Your spine - including your neck, should not be anything but straight/aligned when your head sinks in. Regardless of what the pillow LOOKS like, it is how your head lays that matters. Latex foam is not like memory foam AT ALL, so don't expect it to be. LF bounces back immediately when you move off of it, and it can last for a very, very long time with proper care. Yes, it does have a natural, rubber odor. This fades a bit with time, but will never go away. After all, it IS a rubber product. EXPECT A SCENT! To keep yourself from being bothered, and to extend the life of the pillow, use TWO different types of pillow covers. As a first layer, I use one meant for encasement from allergens and bugs. It's waterproof (not vinyl, and not loud). It's the kind that cannot go in the dryer after being washed. The second layer is a simple cotton cover/case that you should wash and dry depending on factors like oil production, frequency in hair washing, and frequency in sheet changing, etc. Using both will dramatically extend the life of the pillow. Water is the enemy. Moisture will cause the foam to break down into pieces. The crumbling is pretty nasty, so avoid it! The case this one comes in is admittedly cheap and pathetic. Not every company has such poor ones, but it won't make a difference if you add the layers I have suggested. *This IS a real latex foam pillow. I have owned enough to know what they smell and feel like. I bought a "medium". I would call it a firm "soft", and so it wasn't for me. Find the right firmness for your neck and sleep needs, and don't blame the damn company for your choice! These ARE the correct height, they smell normal, and the price is average (they're ALL overpriced)! *This does not seem like a completely latex product, but it is close enough that if it were actually medium firmness, I would have kept it.

Perfect size, perfect pillow.
Size: Queen (High Loft), Number of Items: 1
For me, This pillow is the be all and end all when it comes to comfort. I simply melt into luxurious sleep. I have had a bad neck since my early 20’s, so a pillow that doesn’t fit me, can break me. I have spent soooo much money on pillows trying to find The One. Foam is the only way to go in that regard. Another aspect about this pillow that is particularly important to me is how well it fits into my satin pillow case, with no room to slide around, or for the material to bunch up. I allowed the pillow to air on a chair for 24 hours before use, but am still getting a slight odor.

Medium firmness is too flat
Size: Standard (Mid Loft), Number of Items: 1
I got the medium firmness, and it is much flatter than it appears in the photo. I like the feeling and firmness of it, but the height is too flat and causes my neck to strain. I had to return.

LOVE IT !
Size: Queen (Mid Loft), Number of Items: 1
I love this pillow. It is just right, firm enough yet soft. My head sinks in and is very comfortable. When I lift my head, the pillow bounces right back into shape. If it lasts, I will buy my family each a pillow as it is wonderful. I woke up with zero neck pain as I typically did when using a standard foam pillow. There is a very light scent yet when I covered the pillow with a protector casing and then a cotton case, there was zero scent. I highly recommend. Especially when compared to the comfort of a very expensive latex pillow my husband uses.
