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.

Great product, affordable price
Size: 1 Fl Oz (Pack of 1)
I’ve tried a lot of hyaluronic acid serums over the years, and honestly, this one surprised me. The Ordinary Hyaluronic Acid 2% + B5 leaves my skin feeling soft, hydrated, and plump without feeling greasy or heavy. As someone in my 50s, I really appreciate products that hydrate without making fine lines look worse, and this one layers beautifully under moisturizer and makeup. What makes it even better is the price. It’s incredibly affordable compared to other high-end hydrating serums that cost 3–4 times as much. You truly get amazing quality for the money. My skin feels smoother, looks healthier, and stays hydrated throughout the day. I will definitely keep repurchasing this product and highly recommend it for anyone wanting affordable, effective skincare.

This serum feels really hydrating and helps my skin look smoother and more refreshed.

Affordable and Lightweight Hyaluronic Acid Serum
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
I absolutely love The Ordinary brand and own quite a few of their skincare products, so I was excited to add this hyaluronic acid serum to my routine. I use it after cleansing my face and before applying moisturizer, and it layers really nicely with the rest of my skincare. One of the things I appreciate most about this product is the packaging. The glass bottle feels high-quality, and the dropper makes application easy and convenient. The serum itself is very lightweight, and a little bit goes a long way, so the bottle should last quite a while. It absorbs nicely into the skin without feeling greasy or sticky afterward. I also really appreciate the clean ingredients and the fact that there are no added perfumes or strong scents, which is important for my sensitive skin and overall preference for non-irritating skincare products. As with most skincare products, I know it takes consistency and several months of use before you can truly judge long-term results and improvements in your skin. Because of that, I cannot fully speak yet on how effective it is overall, but so far I have been enjoying using it and have had no irritation or issues. For the affordable price point and quality ingredients, I think this is a great skincare product, and I plan to continue using it and update my review later on with long-term results.
