Understanding Soil pH: Why It Matters for Your Plants’ Health

Soil pH might sound like a topic for science class, but it’s one of the most important factors for healthy, thriving plants. The right pH helps your plants absorb the nutrients they need to grow strong, lush, and vibrant. Luckily, understanding soil pH doesn’t have to be complicated—especially with OKO’s smart sensor doing the hard work for you.

What Is Soil pH?

Soil pH measures how acidic or alkaline your soil is on a scale from 0 to 14:

Acidic soil: Below 7
Neutral soil: Around 7
Alkaline soil: Above 7

Different plants thrive in different ranges. For example:

Acid-loving plants: Blueberries, azaleas, and ferns love soil with a pH between 5.0 and 6.0.
Neutral lovers: Most vegetables, like tomatoes and cucumbers, prefer a pH of 6.0–7.0.
Alkaline enthusiasts: Lavender and rosemary do well in pH above 7.0.

Why Does Soil pH Matter?

Think of soil pH as a key that unlocks nutrients for your plants. When the pH is just right, your plants can absorb essential elements like nitrogen, phosphorus, and potassium. Too far out of range, and those nutrients get “locked up,” leaving your plants hungry—even if you’re fertilizing.

Common issues caused by pH imbalances:

Too acidic: Yellowing leaves, stunted growth.
Too alkaline: Leaves with brown edges or weak flowering.

How OKO Simplifies pH Monitoring

Traditionally, testing soil pH involves kits, strips, and guesswork. With OKO’s sensor, you get real-time, accurate readings of your soil’s pH directly on the app. It even provides species-specific recommendations, so you’ll know if your Peace Lily needs an acidity boost or if your lavender is thriving as-is.

Tips for Balancing Soil pH

Adjusting Acidic Soil: Add garden lime to raise the pH gradually.
Lowering Alkaline Soil: Use sulfur or organic matter like coffee grounds.
Plant-Specific Care: Group plants with similar pH needs for easier management.
Regular Monitoring: Consistency is key—OKO helps you track changes effortlessly.

By understanding and managing soil pH, you’re giving your plants the foundation they need to grow and thrive. With OKO, balancing soil pH becomes a seamless part of your plant care routine.
