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.

Works amazingly, but only if you install it correctly.
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
If you purchasing Siless Liner 157 mil (4 mm) Sound Deadening mat, to block unwanted sounds in your car, this is what you need to buy. But wait! It's not the only thing you need to buy if you want to "actually" deaden sound. By itself, it will definitely block a noticeable amount of sound, and, most likely, that's all you realistically need. But... But... If you want the Siless Liner Sound Deadening Mat to really help you take it up a few notches, to get the best sound almost bordering on soundproofing, listen up. You will have to install traditional butyl rubber first. Doesn't have to be the Siless brand, but I'm sure they would love to sell both to you, I used both Killmat (80mil) and Noico (50mil). I have a Honda S2000. It's a two-seater convertible sports car if you don't know what this car is, and it's loud when I'm driving above 60mph. I also happen to have a sound system installed as well. Other than that, the car is stock. I first installed the butyl rubber on the car's interior sheet metal. I went all out and covered everything I could. I didn't need to but I wanted to. I was extremely impressed with the results. But I wanted to go further. Not because I needed to but because just wanted to see what it would be like. So I bought Siless Liner 157 mil (4 mm) 36sqft Sound Deadening mat to go on top of the butyl rubber mats. I put this over every area I installed the butyl rubber. I had to be careful of clearance issues since I added a significant amount of underlayment, and you should too. If you put butyl rubber sound-deadening materials in 50% of the total interior area, you'll hear a noticeable improvement. If you put butyl in about 80% of the total area, you'll be even more amazed at the improvement, compared to before. I originally did all the above myself, so that's my experience and so your mileage may vary. I then installed the Siless Liner Sound Deadening mat over every place I could even going further than I could with the butyl rubber. I used the Siles Liner in areas where butyl rubber would not have been effective, such as the roll bar hoop area and large empty cavities or holes. I covered everything I could, firewall, doors, floor pan, transmission tunnel, trunk, trunk lid, fuel tank area, rear quarter panels, and rear-wheel tunnels, in Siless Liner Sound Deadening Mat. WOW!! The Siless Liner Sound Deadening Mat was the icing on the cake! Let's not forget, this car is a convertible sports car so it will never be a quiet ride, ever. But I can now actually have a conversation with a passenger at a normal-ish volume! This also means I can now have a normal hands-free phone call without having to plug one ear to block out the noise! My sound system sounds so much better! Just by going through the install process, I looked for any vibration, rattle, squeak, and noise-prone areas to either eliminate or reduce unwanted noise production. If you forget this step, the inside and outside of your car will rattle and buzz. I skipped this step the first time around. But did it right before I installed more butyl rubber and the improvement was impressive, especially inside the car. Outside the car, I didn't notice a difference until I put the last layer of Siless Liner Sound Deadening Mat. The sound deadening mat works both ways from what I can tell. If I turned up my music, as loud as I occasionally do, parked in the attached garage to the house, with the garage door closed, I would be barely able to tell the car was playing music in the garage. It sounds like it is another car, just a little bit down the street, with a very loud base. If you stand 20 feet away outside the car, the sound system is noticeable, but not obnoxious by a long shot. Get a 3 piece wood/metal roller set as well, which makes quick work of large areas.

Better than Kilmat
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
Great adhesion, and you can immediately see the sound difference when you rap the area and compared it to another area without it. Also, very easy to cut and apply. Once on, you may not be able to peel it and reposition it, so be sure where you want it.

High quality, super sticky, very effective
Style: 30 sqft
As long as the surface is thoroughly cleaned, these mats will stick to just about anything. They provide my car with a tremendous amount of sound dampening and have made riding in the car 10 times more enjoyable. I drive a Toyota Yaris and although the engine is built like it's meant to last forever (imagine that), the rest of the car is not of high quality. Which means we used to get A LOT of noise coming from the road, other cars, etc. After I installed these mats which, by the way, I wasn't able to install on every surface I wanted to install them on (due to lack of tools to be able to disassemble certain parts of the interior), the noise coming from outside the car is nearly completely gone. I covered the underside of my hood, the entire interior part of the hatchback, most of the floor in the trunk / spare tire well, and the entire interior side of the doors. The parts I couldn't get to (or didn't want to) were: the ceiling, underneath the driver & passenger seats, behind the dash and the floor for the 2nd row seating. As you can see I left a lot of surfaces untreated with this product AND STILL it blocks most of the sound. To note: people recommended getting the roller tools to help install these mats. I got a few of them in different sizes and they worked O K. Not because of the quality of the tool but because some places you need to install these mats in don't have enough clearance to use the tool. That being said, for the larger surfaces, the roller tools help a lot. Also I found it very beneficial to use aluminum tape while installing these. The tape I used is specifically designed for materials that undergo high temperature changes (like your dryer vents, etc.). This wasn't because the mats were not sticky enough but because there were some places I installed the mats with small gaps between them. I'd also recommend getting some kind of fluffy insulation-type material for large spaces that need noise dampening. Rock wool, for example, worked great for me. As an example, the interior sides of the 2nd row seating walls had large spaces between the plastic interior cover and the metal part of the car wall. I'd install the mats on the metal but was left with 6" - 7" of space between it and the plastic cover. I chose to fill those spots (and spots like it) with insulation which provided EVEN MORE noise dampening.
