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.

It works well, but it’s expensive and greasy
Size: 6 Fl Oz (Pack of 1)
As far as sun protection goes, this has worked perfectly for my family. Spray it on, blend it in, good to go. No sunburn. There are a few annoying things about it though. The price is incredibly high, imo. It is unscented, which is rare for sunscreen, but it smells like alcohol when wet. Also, this stuff is oily. It makes everything it touches greasy looking (hair, clothes, hands…) I like this overall for an alternative to thick mineral sunscreens. It’s pretty convenient.

Great for sensitive skin
Size: 2 Fl Oz (Pack of 1)
I have extremely sensitive skin and recently found out my skin hates the sun due to my autoimmune issues. This sunscreen doesn't break my skin out, keeps me from getting sunburnt and doesn't have a bunch of fragrance. This travel size has been perfect for throwing in my bag for a day at the baseball park or beach. This is a non greasy and no whitecast spray that has a high spf too. I highly recommend it.

Apply BEFORE leaving the house!
Size: 6 Fl Oz (Pack of 1)
I have fair (freckle don’t tan, burn easily then peel and back to white) and sensitive skin. So does my son. I live on the coast, in a southern state and vacation in the Caribbean often. After too many years of getting burned, I finally found Coola a couple years ago. It has revolutionized my time in the sun. Here’s the thing tho. If you don’t apply it properly, it’s not gonna work. If you’re looking for something to put on AT the pool or beach, go for something else (with zinc oxide preferably). If you’re willing to take 5 mins before you go to do it, you’ll be very happy. Kids especially are hard enough to get covered before they see water anyway! Here’s some tips: Spray everyone OUTSIDE (even the unscented can overwhelm inside, and you really don’t need to be breathing in ANY sunscreen) DO NOT USE ON FACE. It will burn your eyes when you sweat/swim. Choose a cream or face stick. Spray until skin is wet. You’re not looking for a light misting, you’re going for full coverage. The can can sound like it’s spraying, but if you don’t see the product on the skin, you’re gonna get burned. Give it 5 mins to dry before putting on shirts/cover ups. Reapply between 2 & 3 hours of water exposure. (We usually dry off, respray, then have a snack or lunch) Give it 15 - 20 mins to soak in before you hit the water again. I’ve found a 6oz can will usually take care of two adults and a child for the day (initial and resprays). It’s a tad expensive, so we use Coola on days we plan to be out for more than a couple hours, or every day in the Caribbean, since the sun is SO intense. The 2oz is ‘touch up’ sized. It may take care of a child’s initial spray, but I’ve found it more suited for adding additional spray to areas that feel a bit crispy, rather than using it on a single application.

Toxic ingredients
Size: 2 Fl Oz (Pack of 1)
There are endocrine disruptors in here that are harmful to your health. I nearly got to the point of being disabled from endocrine issues. Has ingredients that ruin fertility, raise risk of cancer, and ruin your endocrine system. I hope these brands can take these ingredients out and begin to care about consumers health.
