We love the idea of bringing nature indoors, filling our homes with vibrant green life. And just like our outdoor gardens, we want to nourish our houseplants using organic methods. But let’s be honest, trying to use traditional organic materials like compost or earthworm castings indoors often comes with a less-than-pleasant side effect: odor. Not exactly the fragrant haven we imagined! Finding an effective, organic indoor plant food that doesn’t make your living room smell like a farm can feel like a real challenge. Good news! One of the best-kept secrets for nourishing indoor plants organically is using fish emulsion indoors. It offers fantastic nutrients without the overwhelming smell, making organic indoor gardening achievable and enjoyable.

The Quest for Organic Goodness Indoors

As indoor plant enthusiasts, many of us are drawn to the principles of organic gardening. We prefer using natural inputs over synthetic chemicals, believing it’s better for our plants and our homes. Applying these principles to our cherished houseplants seems like a natural step.

However, many common outdoor organic fertilizers simply aren’t practical for indoor use. Bagged compost and worm castings, while wonderfully beneficial in the garden bed, can carry unwanted odors, attract pests, or simply create too much mess inside. It’s a common dilemma – how do you feed your indoor plants organically without turning your home into a compost bin?

Deodorized Fish Emulsion: A Breath of Fresh Air for Houseplants

This is where deodorized fish emulsion steps in as a real hero for the indoor organic gardener. Fish emulsion is a traditional liquid fertilizer made from the by-products of the fish processing industry. It’s a power-packed source of nutrients, particularly nitrogen, which is crucial for healthy, vigorous leafy growth.

The key difference for indoor use is the “deodorized” part. Manufacturers process the fish emulsion to significantly reduce or eliminate the strong, fishy smell that’s characteristic of the standard product. This makes it a perfectly viable, nutrient-rich organic option that you can use inside your home without needing a clothespeg for your nose! Look for brands specifically labeled “deodorized” or “for indoor use.” Many reputable organic brands offer this option, often bearing certifications like the OMRI seal.

Applying Fish Emulsion to Your Indoor Green Friends

Once you’ve got your bottle of deodorized fish emulsion, using it is straightforward. The most important thing to remember is that this is a concentrated product, so dilution is essential.

Dilution is Key

Never use fish emulsion concentrate directly on your plants. Always dilute it with water according to the instructions on the product label. Ratios can vary between brands and whether they recommend it for indoor versus outdoor use. For indoor plants, it’s often wise to use a slightly weaker dilution than recommended for outdoor plants, especially when you’re first starting out. Start with maybe half or even a quarter of the strength suggested for outdoor containers. This helps prevent nutrient burn, which can happen if the fertilizer solution is too strong.

Feeding Frequency

Indoor plants generally require less frequent feeding than outdoor plants. It’s best to fertilize during their active growing season, which is typically spring and summer for most houseplants. A common schedule is to feed every 2-4 weeks using your diluted fish emulsion solution. As fall approaches and light levels decrease, most plants enter a period of slower growth or dormancy. Reduce or stop fertilizing completely during the fall and winter months until growth resumes in the spring.

How to Water It In

Before applying the fish emulsion solution, it’s a good idea to water your plant thoroughly with plain water until it drains from the bottom. This ensures the roots are hydrated and helps distribute the fertilizer solution evenly through the soil, preventing potential root shock. After the initial watering, apply the diluted fish emulsion solution to the soil surface, watering gently until you see it begin to drain from the bottom of the pot. Try to avoid getting the solution directly on the leaves, especially if your plant has fuzzy foliage, as this can sometimes lead to spots or issues.

Managing Drainage: Keeping Surfaces Stain-Free

Even with deodorized fish emulsion, the water that drains out the bottom of the pot may have a slight brown tint. This is just natural color from the organic material. While it doesn’t smell, you still want to avoid staining your floors or furniture. Here are a couple of simple methods to manage this:

The Gravel Tray Method

Place a layer of gravel, pebbles, or even clay LECA balls in the bottom of the drainage saucer or tray your pot sits on. Place the potted plant directly on top of the gravel layer. When you water (including with fish emulsion), the excess water drains through the pot’s holes and collects in the gravel below. The gravel keeps the bottom of the pot elevated, ensuring the plant’s roots aren’t sitting directly in standing water, which can lead to root rot. The tinted water is safely contained in the tray.

The Bulb Baster Solution

Keep a turkey baster or a large pipette handy. After watering and allowing the excess to drain into the saucer or gravel tray, use the bulb baster to suck up the collected water from the tray and empty it into a bucket or sink. This is particularly useful if you’re using a cachepot (a decorative pot without drainage holes that holds your plant in its plastic nursery pot) or if you want to ensure no water overflows the gravel tray. Be careful when transferring the water to avoid spills.

Bottles of liquid organic fertilizers, suitable for indoor plants, with emphasis on proper dilution.

Using Cachepots

As mentioned above, placing your potted plant inside a slightly larger decorative pot without drainage holes is another common practice. To use this with fish emulsion, ensure there’s a layer of gravel, pottery shards, or specific pot risers at the bottom of the cachepot to lift the plant’s inner pot by an inch or two. Water the plant until it drains into the bottom of the cachepot. Periodically check the cachepot and use a bulb baster to remove any standing water collected below the plant’s pot. This keeps the drainage water contained and off your surfaces.

Beyond Fish Emulsion: Other Organic Indoor Options

While deodorized fish emulsion is a fantastic option, it’s not the only organic liquid fertilizer suitable for indoor plants. Exploring other options can also benefit your green friends.

Organic Hydroponic Nutrients

These products are formulated as liquid organic nutrients, often designed for soilless growing systems like hydroponics. Many are completely odorless and provide a balanced range of nutrients. They can be an excellent, clean option for potted plants as well, typically used diluted in water according to package directions.

DIY Indoor Fertilizers

If you enjoy a bit of DIY, you can also create some simple organic boosts at home:

• Gelatin Water: Plain, unflavored gelatin is almost pure nitrogen. You can dissolve a packet in hot water, then dilute it significantly with cold water until it’s no longer warm. Apply this diluted solution to your soil. It provides a simple nitrogen boost to encourage leafy growth.
• Fermented Banana Peel Water: Banana peels are rich in potassium and phosphorus. You can chop up a few peels, place them in a jar, fill it with water, and let it sit for about a week. The liquid will become infused with nutrients. Strain out the solids and use the nutrient-rich water (diluted if it seems very strong) when watering. It might sound a bit quirky, but gardeners have been using kitchen scraps forever! While less likely indoors than out, it’s always a good idea to keep an eye out for any unwanted insect visitors just in case.

Top Tips for Fertilizing Indoor Plants

Regardless of which organic fertilizer you choose, here are a few general tips for successful indoor plant feeding:

• Don’t Fertilize Stressed or Dormant Plants: Avoid feeding plants that are already struggling from issues like overwatering, underwatering, or pests. Wait until they recover. Also, as mentioned, hold off on fertilizing during their natural rest period (usually fall and winter).
• Always Water Before Fertilizing: Applying fertilizer to dry soil can shock roots and lead to root burn. Water first, then apply your diluted fertilizer solution.
• Start Weak: If you’re unsure about dilution rates, it’s always safer to start with a weaker solution than recommended and gradually increase if needed. Too little fertilizer is easier to fix than too much.
• Observe Your Plants: Pay attention to your plants. Pale leaves might indicate a nitrogen deficiency (where fish emulsion helps!), but slow growth could also be related to light, water, or temperature. Learning your plants’ signals is key.

In conclusion, using organic fertilizers indoors is absolutely possible without sacrificing comfort or cleanliness. Deodorized fish emulsion is a fantastic, nutrient-rich option that effectively tackles the common odor problem. By diluting properly, applying thoughtfully, and managing drainage, you can give your indoor plants the organic boost they need for lush, healthy growth. Supplementing with other organic liquids or even simple homemade concoctions adds more tools to your organic indoor gardening arsenal.
