Root rot is a silent killer. One day your plant looks fine, and the next it’s wilting, yellowing, and collapsing. If you’ve ever lost a beloved houseplant to this nasty problem, you know how frustrating it can be. But the good news? Root rot is preventable. You don’t need a greenhouse or a green thumb, but just a bit of know-how and consistency.
Here are three simple steps to avoid root rot and keep your plants thriving.
Water Only When Necessary
The number one cause of root rot is overwatering. Most plants hate sitting in soggy soil. Roots need oxygen, and too much water suffocates them, leading to decay. The fix? Don’t water on a schedule but instead water based on the soil's condition.
Use the finger test. Stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it’s still damp, leave it alone. For more precision, consider a moisture meter. They're cheap, easy to use, and take out the guesswork.
And when you do water, do it thoroughly. Water slowly until you see liquid draining from the bottom of the pot. This ensures the roots are evenly moistened without drowning them.
Use Well-Draining Soil
Even perfect watering habits can’t save a plant stuck in dense, compacted soil. That’s why choosing the right mix is key. Most houseplants do best in soil that drains quickly and allows air to reach the roots.
For succulents and cacti, use a gritty, sandy mix. For tropical plants like pothos or monstera, a blend of potting soil, perlite, and orchid bark creates the ideal balance of drainage and moisture retention. Avoid heavy garden compost as it holds too much water and compacts easily, both of which can lead to root rot.
Pssttt! Want to skip the guesswork? Our GrowTropicals Houseplant Potting Soils are tailored for different plant types and optimised for drainage, breathability, and root health. Just open the bag, pot your plant, and you're good to grow.
Pick the Right Pot
Your plant’s pot plays a bigger role than you might think. Always choose a container with drainage holes (this is a big non-negotiable!). Without them, excess water collects at the bottom, setting the stage for root rot.
Avoid pots that are too large. It might seem generous to give roots room to grow, but oversized pots hold more soil, which holds more water, which raises the risk of rot. Match the pot size to the plant’s current root ball, and size up slowly over time.
Bonus tip: Terracotta pots are porous, which means they help wick moisture away from the soil. They're a great choice for plants prone to overwatering issues.
Avoiding root rot is all about good habits. By watering only when needed, using well-draining soil, and picking the right pot, you can keep your plant’s roots healthy and your greenery thriving. Simple steps, big impact.
