Stop Overfeeding Your Plants: The Truth About Fertilizing Houseplants

One website says to fertilize every week. Another says once a month. Your plant label suggests something totally different. Sound familiar? With so much conflicting advice online, it’s no wonder houseplant enthusiast feel overwhelmed when it comes to fertilizing. If you’ve ever asked, “Am I doing this right?”, this article is for you. We’re cutting through the confusion to debunk the biggest houseplant fertilizing myths—and giving you clear, practical tips for feeding your plants the right way, at the right time.

If you’ve ever found yourself wondering, “Am I fertilizing my houseplants enough—or too much?”, you’re not alone. Fertilizing indoor plants is one of the most misunderstood parts of plant care. The truth is, many plant parents (especially beginners!) are overfeeding their houseplants, thinking it will lead to bigger, better, faster growth.

Spoiler alert: it doesn’t. Over-fertilizing can actually harm your plants more than help them.

In this post, we’re busting the most common houseplant fertilizer myths and teaching you the right way to feed your indoor plants for healthy, thriving growth.

Myth #1: More Fertilizer = More Growth

It’s easy to assume that giving your plants more food will lead to faster or fuller growth. But houseplants don’t work like that. Overloading them with fertilizer can burn their roots, cause leaf damage, and lead to long-term stress.

The truth: Houseplants grow at a natural pace. Fertilizer is a supplement, not a magic potion. Think of it like vitamins for your plant—not a meal. A little goes a long way.

🌿 Myth #2: You Should Fertilize All Year Long

Many plant owners unknowingly continue fertilizing through the fall and winter, but most houseplants go into a rest period during the colder months. Less light and cooler temps slow their growth, meaning they need fewer nutrients.

The truth:

• Spring and summer are the best times to fertilize houseplants.
• Fall and winter are typically dormant seasons for most indoor plants.
  Feeding them during this time can result in nutrient buildup in the soil and cause more harm than good.

👉 Pro Tip: Watch your plants. When they start putting out new growth in spring, it’s the perfect time to resume fertilizing.

Myth #3: All Houseplants Need the Same Fertilizer

Using the same fertilizer on your monstera, succulents, and African violets? That’s a no-go. Different houseplants have different nutrient needs depending on how they grow and what kind of soil they prefer.

The truth:

• Foliage plants (like pothos and philodendron) benefit from balanced or nitrogen-rich fertilizer.
• Flowering plants (like peace lilies or African violets) need phosphorus-rich formulas.
• Succulents and cacti do best with low-nitrogen, diluted fertilizer.

👉 Look for fertilizers labeled for your specific plant type, or choose a gentle, balanced indoor plant fertilizer (like 10-10-10 or 20-20-20) and dilute it.

❗ Myth #4: Homemade Fertilizers Are Always Better

Eggshell water. Banana peels. Coffee grounds. The internet is full of homemade fertilizer hacks. While some may offer a nutrient boost, they’re not always safe for your houseplants—and can lead to mold, pests, or even root damage if overused.

The truth:
Homemade solutions don’t offer consistent nutrient ratios and can cause more problems than they solve. It’s best to stick with tested, well-balanced houseplant fertilizers—especially if you’re still learning the ropes.

Now that we’ve debunked the myths, let’s talk about what actually works.

📌 Fertilizing Tips for Indoor Plants:

• Feed during the growing season (spring through summer)
• Use a diluted liquid fertilizer every 2–4 weeks or a slow-release formula every 2–3 months
• Always water before fertilizing to avoid root burn
• Skip fertilizing if your plant is stressed (recently repotted, battling pests, etc.)
• Flush the soil every few months to remove salt buildup
