The Ultimate Guide to Plant Health Diagnosis

Struggling to figure out what’s wrong with your plant? This ultimate 2025 guide to plant health diagnosis covers the most common problems — from yellow leaves to pests — and shows you exactly how to bring your plants back to life.

Step 1: Look at the Leaves

  • Yellow leaves = over/underwatering or nutrient deficiency.
  • Brown tips = low humidity or excess fertilizer.
  • Spots = fungal or bacterial disease.
  • Drooping = water stress.

Step 2: Check the Soil

Is it soggy, dry, or moldy? Soil condition is often the root cause of plant health issues.

Step 3: Evaluate Light and Location

Plants in low light often fade, while those in harsh sun burn.

Step 4: Inspect for Pests

Look under leaves for mites, aphids, or mealybugs. Use a magnifying glass if needed.
