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.

Healed my barrier so fast
Size: 3.38 Fl Oz (Pack of 1)
I received this ampoule yesterday and I'm already leaving a 5 star review after 2 uses because it just worked so well. I bought it because I've recently incorporated the Timeless 20% Vitamin C into my routine and that + my tretinoin made my skin drier than I've ever felt it before, even gently swiping a cotton pad with micellar would sting on some parts of my face. As soon as this ampoule arrived I applied it to clean skin and layered squalane on top (my moisturizer was burning as well.) This product did not sting my face AT ALL. It instead felt immediately soothing and hydrating. When I woke up this morning almost all of my redness was gone, my skin didn't feel tight or irritated, and my skin tone looked so even and glowy. I never thought a product, especially such a simply formulated one, could heal my barrier so quickly but that's exactly what it did and I can already tell it's a repeat buy. If you have redness prone sensitive skin and/or you use several high strength actives, this ampoule is a must have and it might be the key for anyone struggling to tolerate high strength retinoids. I got the largest size bottle for $15 on sale and it's seriously one of the most affordable and effective skincare products I've ever had in my routine.

Safe, Lightweight, Hydrating – Perfect for sensitive, super oily, acne-prone skin
Size: 1.85 Fl Oz (Pack of 1), Size: 1.85 Fl Oz (Pack of 1)
I care most about the ingredients, and this Madagascar Centella Ampule is excellent — all the ingredients are safe, with no potential harm to your health, and it’s Yuka app approved with a 100/100 safety score. I feel confident using it on my sensitive, super oily, acne-prone skin. It’s super lightweight, absorbs quickly, and is not sticky at all — after applying, you just feel comfortable hydration. Even after a few hours, my skin doesn’t get oily, unlike some other serums I’ve used. It helps calm my skin and restore the barrier, which is perfect for my skin type. Even when I have acne wounds, it doesn’t irritate or sting — it’s extremely gentle. For sensitive, super oily, acne-prone skin like mine, it works wonderfully. Living in Utah, one of the driest states in the U.S., this serum keeps my skin hydrated even in very dry conditions, and a little goes a long way — 1–1.5 drops cover my face and neck. Using more can make my skin slightly oily, so just the right amount works perfectly. For someone with dry skin, results may differ, but for my skin type, it works beautifully. It’s also super affordable, and I’m glad it’s available on Amazon, with occasional great deals at Costco. I appreciate that it’s accessible at this price because this serum helps my skin a lot — very gentle on my acne-prone, sensitive, super oily skin. The serum is super easy to apply with the dropper, which keeps other things from getting into the bottle — it’s perfect for easy, hygienic application. Just note that the bottle is glass, so be careful — it may break if dropped. I’ve only been using it for three weeks, but it’s already a staple. I currently use one bottle, and the other two are extra for long-term use, especially since I got them on a great deal. This is now my main hydration serum, and I’ll update after longer use if needed.

Very impressed
Size: 3.38 Fl Oz (Pack of 1)
Really impressed by this serum! Got this to soothe my skin after overdoing it with too many different “actives”, and it gently and quickly got rid of redness and flaking, restored my skin barrier, and left my skin so moisturized and supple that I didn’t even feel like I needed lotion or cream afterwards. And it’s a GENEROUSLY sized glass bottle, too! I will definitely be trying other products from this brand!

Best skincare product ever
Size: 3.38 Fl Oz (Pack of 1)
This ampoule is THE BEST THING EVER. I’ve been in the skincare industry since 1996 and I’ve never used a product that works as well as this. I have sensitive oily skin and it has a lot of redness. After the first use the redness was completely gone and the hydration was noticeable. Do not pass on this stuff! Highly recommend it for anyone wanting immediate hydration. It’s thin and isn’t sticky or tacky. It feels like I don’t have anything on my face but the benefits are definitely noticeable.

Good product, but requires consistent use
Size: 1.85 Fl Oz (Pack of 1), Size: 1.85 Fl Oz (Pack of 1)
I’ve been using this centella ampoule for a while now, and overall I like it. The texture is lightweight, absorbs quickly, and leaves the skin feeling hydrated and soothed. It’s especially nice for sensitive or irritated skin. However, one important thing to note is that the results are not immediate. In my experience, you start seeing improvements with consistent, long-term use rather than overnight. If you’re patient and use it daily, it can definitely help improve your skin’s appearance. Overall, it’s a good product, but it requires consistency to see full results.
