Okay Inches! The Fertilizer Glow-Up Your Plants Need
When your leafy plants start pushing out new growth, it’s time to feed them!
Alright, let’s talk fertilizer. When do your indoor plants actually need it? The short answer: only when they’re actively growing.
Many plants go dormant in the winter, meaning they slow down growth due to less light. Fertilizing during dormancy can overload them with nutrients, leading to unabsorbed fertilizer buildup and potential root burn. So, let’s break down when and how to fertilize your indoor plants the right way.
When Should You Fertilize?
You’ve probably heard the classic “No fertilizer in winter!” rule, but that only applies to plants that actually go dormant. Some plants keep growing year-round, especially if they have enough light.
How can you tell if your plant is ready for fertilizer?
Easy—look for signs of new growth. If you see fresh leaves or new growth points, it’s time to give your plant some extra love.
Choosing the Right Fertilizer
Cacti and succulents don’t need frequent feeding, but when they do, a low-nitrogen fertilizer is best— like the one pictured here. Check out our fertilizers!
Alright, so you’ve got new growth. Ayy, okay, inches! Now what? Which fertilizer should you use?
First, figure out what plant you’re fertilizing because different plants have different needs.
Cacti & succulents – Need lower nitrogen fertilizers, like 2-7-7
Leafy houseplants (Pothos, Monstera, etc.) – Prefer a balanced, nitrogen-rich fertilizer, like 10-10-10.
What’s in Fertilizer?
There are three main nutrients in fertilizers:
Nitrogen (N) – Encourages lush, green leaves.
Phosphorus (P) – Supports strong roots and flowers.
Potassium (K) – Helps plants resist disease and tough conditions.
Your plant’s needs determine which fertilizer ratio to choose. If it’s all about the foliage, go for something nitrogen-heavy. If you want stronger roots or flowers, look for more phosphorus.
Types of Fertilizers
For a low-maintenance approach, slow-release fertilizers provide steady nutrients over time, making plant care even easier.
Not sure where to start? Find a local plant shop or nursery—they can usually recommend the best option for your plants. But here’s a quick rundown:
Liquid fertilizer – A favorite for houseplants, especially for water propagations. It’s easy to use and quickly absorbed.
Granular fertilizer – Sprinkled on top of the soil, releasing nutrients as you water.
Time-release fertilizer – Tiny pellets that gradually break down over time, meaning fewer applications.
Organic fertilizer – Natural and eco-friendly, like worm castings or compost tea.
One quick note: Liquid fertilizer isn’t always water-soluble. If you’re fertilizing plants in water (like in a propagation station), look for water-soluble or hydroponic fertilizers that fully dissolve so roots can absorb them properly.
That’s it! Keep an eye on your plants, fertilize when they’re actively growing, and pick the right formula for their needs. Now go help those plants thrive!
