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.

Awesome versatility, affordable, easy to use micro needles for compatible Dr. Pen devices 🫶🏽💉🤩⭐️
This microneedling cartridge refill set is a pretty great value with a convenient mix of multiple needle options. It’s super versatile and should easily meet all your microneedling skincare needs. The cartridges fit securely with compatible Dr. Pen models (mine is 7). MAKE SURE YOURS FITS!! Some devices THREAD, others DO NOT!! This is super important b/c if you don’t have the correct type, there’s nothing you can do to make them work! These refills allow for easy and effective operation without causing skin snagging, tears, or injury (other than ‘micro injury,’ which is what’s intended by the whole concept of Microneedling!). The individually sealed cartridges are sanitary, convenient for travel, and are an excellent choice for any microneedling skincare regimen. While the plastic housing/casing feels somewhat lightweight, the kit’s performance is actually top notch. I do wish they had protective caps for even more superior protection, but it’s a great deal and I can’t complain for the price. It’s a total no-brainer if you have a compatible Dr. Pen Microneedling device.

Fit My Dr Pen M7 Correctly, But Check Packaging Carefully Before Use
I purchased these replacement cartridges for my Dr Pen M7, and the fit was fine with no compatibility issues. They attached properly and worked as expected during use, so at least from a fit/function standpoint, they seem pretty standard. I also appreciate that the pack includes a variety of cartridge types and needle/pin counts instead of only one style. Having different options is useful depending on the area being treated and personal preference. One thing I did notice though is that the cartridges arrived in Dr Pen branded packaging, and I honestly wasn’t completely sure about the legitimacy/authenticity of them. They may very well be genuine, but it did make me pause a little since there wasn’t much additional verification information included. My biggest concern was that although the packages are labeled sterile, I noticed some type of brown residue/spotting inside one of the sealed cartridge packages. It appeared in multiple spots inside that particular package, so I immediately decided to throw that cartridge away rather than risk using it. Because of that, I would strongly recommend inspecting each cartridge carefully before use and sterilizing again yourself for extra precaution. With microneedling products especially, cleanliness and safety matter a lot. Overall, the cartridges themselves fit and functioned properly with my device, and I like the variety included, but quality control/sterility is something I’d advise paying close attention to before using them.

Great replacement micro needling cartridges.
Picked today up for replacements for my Dr Pen micro needler. They arrived individually sealed, ready for use. They appear to be compatible good quality product just like my originals. Love the price point and savings. They fit my device perfectly. These arrived at the Dr Pen cartridge box although do not have Dr Pen brand on cartridges appear high-quality similar in packaging of the originals. They do not have the pen, cap safety guard, but that's really not a needed part of the product. Make sure to verify you have the right device. Be aware they do not fit correctly in M8 devices. Great value for the money you get 21 piece micro, needling cartridges, various needle styles. The kit comes with 36 needle, 12 needle and nano cartridges. I have already used the Nano cartridge and they are super comparable to original cartridges quality, They do not drag on the skin easily move and dispense face serum product. So far, I've been super happy with the replacements.

21 Piece Pen Cartridges
This 21 piece microneedling cartridge set is an excellent value and gives a lot of versatility for different skincare needs. I really like that it includes three different tip styles: nano, 12 pin, and 36 pin. There are 7 of each variety included, which makes it easy to customize treatments depending on what area I’m focusing on and how gentle or intensive I want the session to be. The cartridges fit my Dr Pen device well and feel securely attached during use. Everything came individually packaged and clean, which is important for at home microneedling routines. The nano tips are great for product infusion and glow-focused treatments, while the 12 and 36 pin options work well for more targeted skin texture care. Overall, this is a convenient and affordable replacement set that’s perfect for anyone wanting multiple cartridge options in one package.

Wish I Knew if it is Surgical Grade Steel
I have a Dr. Pen A6, and these non-OEM cartridges are a great value. You receive twenty-one cartridges in various sizes, and each cartridge is individually wrapped. These pins come in three sizes: thirty-six pin, twelve pin, and nano. I had no issue inserting the cartridge and locking it into place, and I didn't notice any wiggling or looseness. The pins were sharp and did not tear or drag on my skin. Of course, you will see small pinpricks where you have treated. One thing I would like to know is whether these are made with surgical grade steel. I would prefer that they are, but I don't see that information anywhere in the listing. That said, I didn't notice any unusual irritation. I now have a good variety of cartridges to be more consistent with my pen usage. I will update this review if I notice anything related to the steel used.
