Roots are your plant’s lifeline. They anchor the plant in place, absorb water and nutrients, and even help it fight off stress. When roots are strong, your plant can better withstand changes in environment, watering routines, and light levels. Some things to remember:

• Anchoring: Roots keep the plant stable and secure in its pot.
• Absorption: Tiny root hairs dramatically increase surface area, pulling water and nutrients from the soil.
• Transport: Water and nutrients travel up through the xylem, while sugars and energy produced by photosynthesis move down through the phloem; a two-way street keeping the whole plant nourished.
• Protection: Roots release compounds that help defend against pathogens and stress, while the root cap protects the delicate growing tip as roots push through soil.

• Firm, white, or light-colored roots
• Even growth above the soil
• A plant that bounces back quickly after watering

On the other hand, unhealthy roots may look brown or black, feel mushy, and give off a sour smell. These are signs of root rot, usually caused by overwatering or poor drainage.

1. Don’t overwater. Roots need oxygen as much as they need water. Too much moisture cuts off airflow and suffocates roots. Always check soil moisture before watering.
2. Choose the right pot. Drainage holes are non-negotiable. Roots hate sitting in soggy soil or standing water.
3. Repot when needed. If roots are circling the pot, pushing out drainage holes, or the soil no longer absorbs water evenly, it’s time for fresh soil and more space.
4. Feed wisely. A balanced fertilizer provides the essential nutrients roots need to grow strong and support lush foliage above ground. We love
5. Mind the soil. Use a high-quality potting mix suited to your plant type. Aroids like Monstera and Philodendron thrive in chunky, well-aerated mixes, while ferns prefer more moisture-retentive blends.

Caring for indoor plants doesn’t stop at the roots! There are a few other essentials that will keep your houseplants thriving year-round:

• Light: Every plant has different light needs. Place sun-loving plants near bright windows, while low-light plants thrive in shadier corners. Rotate your plants regularly so they grow evenly on all sides. Add a plant light for those darker winter months like the We the Wild Instant Sun Grow Light.
• Water: Instead of sticking to a strict schedule, check the soil moisture with your finger before watering. Most indoor plants prefer soil that dries slightly between waterings.
• Humidity: Many houseplants, especially tropical varieties, appreciate extra humidity. Try grouping plants together, misting occasionally, or using a small humidifier.
• Repotting: Give your plant a bigger pot and some fresh soil if it's growing out of it's current home. Our new Tonka Terra Indoor Potting Mix is the perfect blend for freshening up indoor plant soil.
• Cleaning: Dust on leaves can block sunlight and also slow growth. Wipe leaves gently with a damp cloth to keep them clean and breathing easily.
• Pest Watch: Check regularly for signs of pests like spider mites, fungus gnats, or mealybugs. Catching issues early makes them much easier to manage.
• Temperature: Keep plants away from cold drafts, heaters, or vents. Most houseplants like the same comfortable temperatures we do, between 65–75°F.

By caring for roots, you’re investing in the long-term success of your houseplants. Think of it this way: happy roots = happy shoots. Next time you admire a glossy leaf or bright bloom, remember to thank the hidden half of your plant — the hardworking root system making it all possible.
