🌿 Every plant parent encounters challenges—it's part of the journey! At Plantes Montreal, we've seen it all, from yellowing leaves to pest infestations. The good news? Most plant problems are easy to fix once you know what to look for. Here's your complete troubleshooting guide to keep your indoor garden thriving.

🟡 Problem #1: Yellow Leaves

🔍 Possible Causes:

💧 Overwatering (Most Common)

Signs: Yellow leaves that feel soft or mushy, wet soil, moldy smell
Fix: Let the soil dry out completely before watering again. Check that your pot has drainage holes. Remove any standing water from saucers. Consider repotting in fresh, well-draining soil if root rot has set in.

🏜️ Underwatering

Signs: Yellow leaves that feel dry and crispy, bone-dry soil
Fix: Water thoroughly until water drains from the bottom. Establish a more consistent watering schedule.

🌞 Too Much Direct Sun

Signs: Yellow or bleached leaves, especially on the side facing the window
Fix: Move your plant to a spot with bright, indirect light or use a sheer curtain to filter harsh rays.

🍃 Natural Aging

Signs: Only the oldest, lowest leaves turning yellow
Fix: This is normal! Simply trim off the yellow leaves to keep your plant looking tidy.

🟤 Problem #2: Brown Leaf Tips or Edges

💨 Low Humidity

Especially common in Montreal winters! Indoor heating dries out the air, stressing tropical plants like Boston Ferns, Peace Lilies, and Calatheas.

Fix:

• 🌫️ Use a humidifier near your plants
• 💦 Mist leaves regularly (morning is best)
• 🪨 Place pots on pebble trays filled with water
• 🤝 Group plants together to create a humid microclimate
• 🚿 Move humidity-loving plants to bathrooms or kitchens

🧂 Salt Buildup from Tap Water

Signs: White crust on soil surface or pot rim, brown leaf tips
Fix: Flush soil with distilled or filtered water. Let tap water sit overnight before using. Consider switching to filtered water for sensitive plants.

✂️ Overfertilizing

Signs: Brown, crispy leaf edges, white salt crust on soil
Fix: Flush soil thoroughly with water. Reduce fertilizer frequency to once a month during growing season only.

🥀 Problem #3: Drooping or Wilting Leaves

💧 Underwatering

Signs: Dry soil, leaves perk up after watering
Fix: Water thoroughly and more frequently. Peace Lilies are famous for dramatic drooping when thirsty—they'll bounce back quickly after a drink!

🌊 Overwatering

Signs: Wet soil, leaves don't perk up after watering, mushy stems
Fix: Let soil dry out. Check for root rot. Improve drainage.

🌡️ Temperature Shock

Signs: Sudden wilting after moving plant or cold draft exposure
Fix: Keep plants away from heating vents, AC units, and drafty windows. Maintain temperatures between 15-24°C (60-75°F).

🐛 Problem #4: Pests

🕷️ Spider Mites

Signs: Tiny webs on leaves, stippled or yellowing foliage, tiny moving dots
Fix: Spray plant with water to knock off mites. Wipe leaves with soapy water. Use neem oil spray weekly until gone. Increase humidity—spider mites love dry conditions.

🦟 Fungus Gnats

Signs: Small black flies around soil, especially after watering
Fix: Let soil dry out more between waterings. Add a layer of sand or pebbles on top of soil. Use yellow sticky traps. Bottom water instead of top watering.

🪲 Mealybugs

Signs: White, cottony masses on stems and leaf joints
Fix: Dab with rubbing alcohol on a cotton swab. Spray with insecticidal soap. Isolate affected plants immediately.

🐚 Scale Insects

Signs: Brown, shell-like bumps on stems and leaves, sticky residue
Fix: Scrape off with fingernail or soft brush. Wipe with rubbing alcohol. Spray with neem oil.

🍂 Problem #5: Leaf Drop

😰 Stress from Changes

Common after: Moving to a new location, repotting, temperature changes, or bringing home from the store
Fix: Give your plant time to adjust (2-4 weeks). Maintain consistent care. Avoid moving it around. This is especially common with Fiddle Leaf Figs!

🌑 Insufficient Light

Signs: Leggy growth, leaves dropping from bottom up
Fix: Move to a brighter location. Rotate plant regularly for even light exposure.

💨 Drafts

Signs: Sudden leaf drop, especially near doors or windows
Fix: Relocate away from cold drafts and heating vents.

🦠 Problem #6: Mold or Fungus on Soil

🍄 White Fuzzy Mold

Causes: Overwatering, poor air circulation, organic matter in soil
Fix: Scrape off mold. Let soil dry out. Improve air circulation with a small fan. Reduce watering frequency. Add cinnamon powder to soil surface (natural antifungal).

🌱 Problem #7: Leggy or Sparse Growth

☀️ Insufficient Light

Signs: Long stems with large gaps between leaves, pale new growth, leaning toward light source
Fix: Move to a brighter location. Prune leggy stems to encourage bushier growth. Consider a grow light for dark spaces.

🌿 Needs Pruning

Fix: Trim back leggy stems just above a leaf node. This encourages branching and fuller growth.

🛑 Problem #8: No New Growth

❄️ Dormancy (Winter)

Normal behavior: Most plants slow or stop growing in fall and winter with reduced light
Fix: This is natural! Reduce watering and stop fertilizing. Growth will resume in spring.

🪴 Root Bound

Signs: Roots circling pot bottom or growing through drainage holes, water running straight through
Fix: Repot into a container 2-3 inches larger in diameter with fresh soil.

🍽️ Nutrient Deficiency

Signs: Pale leaves, slow growth during growing season
Fix: Fertilize monthly during spring and summer with balanced liquid fertilizer diluted to half strength.
