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 feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

A lovely gentle cleanser - good for rosacea-prone skin
I have also purchased the Thayer's Milky toner and really liked it. I normally use oil-based cleansers, like Beauty of Joseon ginseng oil cleanser (which I still do love), and Cosrx makes a snail mucin cleanser that I use for cleansing off makeup or sunscreen and it's very nice. But for my daily regular wash, particularly in the morning, I like a very gentle easy-to-wash-off cleanser that hydrates and soothes. This Thayer's has no perfumes/fragrances! Good for rosacea-prone skin. Hydrates and soothes very well. It didn't strip my skin, wasn't oily at all (though good oil-based cleansers do feel oily they don't stay oily), and felt wonderful as I cleansed my skin - also washed away very easily and quickly; I do about 14 or so splashes of water to be sure all is removed then use a washable reusable toner pad with toner to remove any lingering residue. It doesn't make my skin feel tight or dry. It is gentle. It doesn't lather up, which I like since I don't use lathering products or soaps on my face. No burning, itching, redness, or any irritation at all. I normally use K-Beauty but Thayer's is one brand I will use that's not in the K-Beauty products category. It really is a lovely cleanser.

Gentle, Hydrating Cleanser That Doesn’t Strip My Skin
I’ve been really enjoying this cleanser so far. The formula feels lightweight, creamy, and hydrating without leaving behind any heavy residue. I especially love that it’s fragrance free and sulfate free because it feels very gentle on my skin and doesn’t leave my face feeling stripped, tight, or dry after washing. The ingredients are a huge plus for me, especially the snow mushroom and hyaluronic acid. My skin feels soft, balanced, and hydrated after every use. I’ve also noticed my skin looking healthier overall since adding this into my routine. Another feature I appreciate is the locking pump, which makes it convenient for travel or storing without worrying about leaks. Overall, this feels like a high-quality everyday cleanser and I’ll definitely continue using it.

Use it for barrier repair and our sensitive skin
This does not remove makeup the best, but my daughter and I use it for barrier repair and our sensitive skin. It helps our skin feel soft and hydrated instead of stripped or tight after washing. Great gentle cleanser for everyday use! This is now part of our monthly subscription because we use it so often.
