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.

Doesn't last
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
This grinder appeared to work great and is one of the few ceramic options available. Unfortunately, the ceramic grinder has already broken inside, detaching from the bottle altogether. There are probably tiny plastic pieces in my leftover peppercorns. Don't buy it unless you want to purchase it every few months, which is unfortunate.

Very nice, work well, good gift at a reasonable price
Size: 2 Count (Pack of 1)
I've owned a few different brands and types of grinders before, and these are quite similar. The last set I purchased had the exact same grinder heads, just on smaller glass bottoms. The grinders on those became, unfortunately, unusable due to clogging that resulted in breakage of the ceramic gear. I worry that, since these new grinders have the same heads on them, that these won't last longer than the last set. However, I read reviews of the "best" grinders out there, and these came just behind a more (much more) expensive set with metal gears instead of ceramic. They'd last longer, you might think, however, it was also mentioned that salt corrodes metal and so that's why the vast majority of grinders, mostly intended for use with salt, are made of ceramic. So why would I spend five times the price on the expensive ones? So far, I'm very pleased with this set. They're much more comfortable to use than my previous set, which had way smaller glass bases. I can really get a good grip on these. The little "dial" on the bottom, to adjust the coarseness of the grind, moves very smoothly on these. It was so difficult to turn the dials on the previous set - and mind you, these are exactly the same as the new ones - that I had to use a pair of pliers to turn them. Strange. I see this identical grinding mechanism on several of the grinders available on Amazon, so it makes sense to assume they're all sourced from the same manufacturer by different vendors. These also hold about twice the amount as my previous set - not a major hassle to refill, but nice not to have to bother with it as often. Quite elegant looking, too. The set comes with a nifty metal holder with prongs on either side that the grinders snap into place securely for transport from kitchen to dining table. They're inexpensive enough that you can easily afford to buy two sets for each end of your table. That's a nice touch if you're having several dinner guests or a large family, so you don't have to pass the salt and pepper around. I guess the $100 set with the metal gears might last longer, even with inevitable salt corrosion, but these will likely last a good long while with their ceramic gears and, if they do break down sooner, at least you could buy four or five of these sets for the same price. I recommend this set.

Love, Love, Love
Size: 2 Count (Pack of 1), Size: 2 Count (Pack of 1)
THIS SET, I LOVE! Absolutely love. When you buy something that you can't see and physically touch- You're always rolling the dice And whether or not you'll like what you receive.. I have bought a few grinder sets in the past, use for a bit and then toss, and back to buy another. This set is a keeper! It washed well, was easy to fill with a wider mouth opening and the grider worked perfectly. I also like having the ability of changing the coarseness, as our household members have different preferences. Looks nice on my table, and the stand was an added bonus. The size is large enough to not have to refill as often but not to big to look out of place. A good price, they look nice, nice grip and durability. I will be buying a couple more sets as gifts to those that have been here for dinner and mentioned that like them as well. I have no 'cons' to list on the product. I love everything about it. Look no further- you'll be pleasantly pleased.

Great value for the money the set works very nicely
Size: 2 Count (Pack of 1)
This is a nice set of Peppermill and salt grinder. The capacity is very nice and it is easy to clean. It’s made of sturdy glass and the top is a very nice stainless. It’s the perfect size for my hands and it distributes a very nicely, ground pepper and salt. I had to switch the salt and pepper from one shaker to another because one was not grinding the peppercorns, but when I switched it to the other, they both worked fine.

Easy to use, pepper doesn't get stuck
Size: 2 Count (Pack of 1)
I'm never going back to an electric grinder again!!! I like my pepper on the fine side - I don't like to bite into a chunk of peppercorn. With those electric grinders, the peppercorns get stuck and the motors don't have enough 'oompf' to plow through. This handy dandy grinder absolutely does! I'm able to easily adjust the size of the grind and the mechanism is smooth and easy to handle. The shape feels good in my hand and the 1/2 cup container is a great size. You don't have to refill it too often. Between the shape of the grinders and the holder, I feel it looks nice on my table. I couldn't be more pleased!!
