Did you know that about 70% of houseplants don’t get enough fertilizer? That means they’re missing out on key nutrients that help them grow strong and healthy. The good news? You don’t need fancy products to fix this. You can make your own natural fertilizers using simple things from your kitchen! Let’s break down which plants need fertilizer, why homemade options are awesome, and how to make your own.
🪴 Which Houseplants Need Fertilizer?
Not all houseplants need fertilizer, but many do—especially flowering ones. If your plant blooms or grows quickly, it probably needs a little extra help. Foliage plants (the leafy ones) might not need as much, but they still benefit from occasional feeding.
If you’re unsure, ask your local nursery or garden shop. And when you do fertilize, go for organic options made for indoor plants. Look for slow-release formulas so you don’t accidentally overfeed. Also, make sure the fertilizer is safe for pets and people—no harsh chemicals!
Signs your plant might need nutrients:
- Leaves turning yellow or pale
- Slow or stunted growth
- Droopy or sad-looking stems
You can also mix in natural boosters like compost, leaf mold, or worm castings to give your soil a nutrient kick.
🌱 Why Homemade Fertilizer Rocks
Making your own fertilizer is:
- ✅ Cheap
- ✅ Eco-friendly
- ✅ Safe for pets and kids
- ✅ Great for your plants
Most homemade fertilizers are packed with nitrogen, phosphorus, and potassium—three nutrients plants need to grow. Plus, they help the soil hold water better and reduce waste (no more tossing banana peels or coffee grounds!).
And the best part? You know exactly what’s going into your plants. No mystery chemicals, no weird preservatives—just good, clean nutrients.
