Is It Normal for Lower Leaves to Turn Yellow and Fall Off?

This is one of the most common questions from plant parents, and the answer is: it depends. Sometimes it’s completely normal, and sometimes it signals a problem. Here’s how to tell the difference:

When It’s Completely Normal

Natural Aging Process

What’s Happening:

  • All leaves have a lifespan
  • Oldest leaves (lowest on plant) die first
  • Plant redirects energy to new growth
  • Part of normal plant lifecycle

Signs This Is Normal Aging:

  • Only the oldest, lowest leaves affected
  • One or two leaves at a time (slow, gradual)
  • New growth at top is healthy and green
  • Plant otherwise thriving and vigorous
  • Leaves turn yellow slowly over weeks
  • Pattern: Yellows → completely yellow → falls off
  • No other symptoms (spots, pests, wilting)

Which Plants Do This Noticeably:

  • Dracaena (constantly dropping lower leaves)
  • Fiddle leaf fig
  • Rubber plant
  • Monstera
  • Philodendron
  • Most tree-like plants

What to Do:

  • This is normal—no action needed!
  • Remove yellow leaves if desired (cosmetic)
  • Or wait for them to drop naturally
  • Continue normal care
  • Appreciate new growth at top

How Often Is Normal:

  • Varies by species and growth rate
  • Fast-growers may drop leaves more frequently
  • One leaf every few weeks to months is typical
  • Seasonal increase in fall/winter (some dormancy)

After Repotting

Why It Happens:

  • Transplant shock
  • Roots adjusting to new environment
  • Temporary stress response
  • Plant shedding leaves it can’t support during adjustment

Signs This Is Normal Post-Repotting:

  • Repotted within last 2-4 weeks
  • Only a few lower leaves affected
  • New growth still forming
  • No other concerning symptoms
  • Plant was root-bound when repotted

What to Do:

  • Be patient—should stop within month
  • Maintain consistent care
  • Don’t fertilize yet (wait 4-6 weeks from repotting)
  • Keep in bright, indirect light
  • Avoid overwatering (less foliage = less water needed)

When to Worry:

  • Excessive yellowing (many leaves)
  • Upper leaves also yellowing
  • No new growth after 6-8 weeks
  • Signs of root rot (mushy stems, foul odor)

When It Indicates a Problem

Overwatering (Most Common Problem)

What’s Happening:

  • Roots sitting in waterlogged soil
  • Can’t absorb oxygen
  • Root rot may be developing
  • Plant drowning

Signs of Overwatering:

  • Multiple lower leaves yellowing rapidly
  • Soil constantly wet or soggy
  • Mushy or soft stems
  • Leaves may have brown spots or edges
  • Foul odor from soil
  • Fungus gnats present
  • Plant wilting despite wet soil
  • Progresses quickly

What to Do:

  1. Check soil moisture—is it soaking wet?
  2. Feel pot weight—very heavy?
  3. Reduce watering immediately
  4. Allow soil to dry out more between waterings
  5. Check drainage holes (are they blocked?)
  6. If severe, may need to repot in fresh, dry soil
  7. Trim any mushy roots if repotting

Prevention:

  • Water only when top 1-2 inches of soil dry
  • Ensure pot has drainage holes
  • Use well-draining soil
  • Empty saucers after watering
  • Reduce watering in winter

Underwatering

What’s Happening:

  • Plant not receiving enough water
  • Sheds leaves to conserve resources
  • Soil too dry for too long

Signs of Underwatering:

  • Lower leaves yellowing (less common than overwatering)
  • Soil very dry, pulling from pot edges
  • Pot feels very lightweight
  • Leaves may be crispy, curled, or drooping
  • Entire plant may look droopy
  • Slow progression usually

What to Do:

  1. Check soil—is it bone dry?
  2. Water thoroughly until water drains from bottom
  3. Consider whether you’re watering frequently enough
  4. Check that water is penetrating soil (may repel if very dry)
  5. May need to soak pot in water for 10-15 minutes
  6. Increase watering frequency

Prevention:

  • Establish consistent watering routine
  • Check plants weekly
  • Don’t let soil become completely dry (unless plant requires it)
  • Set reminders

Insufficient Light

What’s Happening:

  • Plant can’t support all foliage with limited light
  • Sheds oldest, least efficient leaves
  • Conserves energy for survival

Signs of Inadequate Light:

  • Lower leaves yellowing
  • Leggy, stretching growth
  • Pale or faded leaf color
  • Slow or no new growth
  • Plant leaning toward light source
  • Long gaps between leaves on stems

What to Do:

  1. Move to brighter location
  2. Closer to window (within 2-3 feet)
  3. Choose south or east-facing window if possible
  4. Consider grow light for dark spaces
  5. Rotate weekly for even light exposure

Prevention:

  • Research light needs for your specific plant
  • Place appropriately from the start
  • Adjust seasonally (winter light weaker)
  • Clean windows to maximize light

Nutrient Deficiency

What’s Happening:

  • Soil depleted of nutrients (especially nitrogen)
  • Plant can’t support all foliage
  • Older leaves sacrificed to support new growth

Signs of Nutrient Deficiency:

  • Gradual yellowing of lower leaves
  • Overall pale appearance
  • Slow growth
  • Small new leaves
  • Plant in same soil for 1+ years without fertilizing
  • Or recently repotted (rare—fresh soil has nutrients)

What to Do:

  1. Begin fertilizing regularly (if you haven’t been)
  2. Use balanced, water-soluble fertilizer
  3. Feed every 2-4 weeks during growing season (spring/summer)
  4. Always dilute properly—half-strength is safe
  5. Water before fertilizing (never apply to dry soil)

Prevention:

  • Fertilize regularly during growing season
  • Reduce or stop in fall/winter
  • Use quality fertilizer
  • Don’t over-fertilize (causes different problems)
  • Repot every 1-2 years for fresh soil

Root-Bound Plant

What’s Happening:

  • Roots have filled entire pot
  • No room for root growth
  • Can’t absorb water/nutrients effectively
  • Plant stressed

Signs Plant Is Root-Bound:

  • Lower leaves yellowing
  • Water drains through very quickly
  • Roots visible through drainage holes
  • Roots circling at soil surface
  • Stunted growth despite good care
  • May need watering constantly

What to Do:

  1. Check roots by removing plant from pot
  2. If severely root-bound, repot immediately
  3. Go up 1-2 inches in pot size
  4. Use fresh potting soil
  5. Loosen outer roots when repotting

Prevention:

  • Repot when roots fill pot
  • Fast-growers: check annually
  • Slow-growers: every 2-3 years
  • Don’t wait until severely root-bound

Pests

What’s Happening:

  • Pests feeding on plant
  • Sap-suckers drain nutrients
  • Plant stressed and declining

Signs of Pest Problem:

  • Lower leaves yellowing
  • Sticky residue on leaves
  • Visible pests (check undersides of leaves)
  • Webbing (spider mites)
  • White cottony masses (mealybugs)
  • Tiny insects flying around plant

What to Do:

  1. Inspect plant carefully for pests
  2. Check undersides of leaves
  3. Look for webbing, sticky residue, or insects
  4. Isolate plant immediately if pests found
  5. Treat appropriately for specific pest

Prevention:

  • Inspect plants weekly
  • Quarantine new plants 2-3 weeks
  • Keep plants healthy (less susceptible)
  • Address pest problems immediately

How to Determine the Cause

Ask Yourself:

  1. How many leaves are affected?

    • One or two = likely normal
    • Many at once = likely a problem

  2. How quickly is it happening?

    • Slow, gradual = possibly normal aging
    • Rapid = likely a problem

  3. What’s the pattern?

    • Only oldest, lowest leaves = often normal
    • Random leaves or upper leaves too = problem

  4. Is new growth healthy?

    • Yes = less concerning (may be normal)
    • No = definitely a problem

  5. What does the soil feel like?

    • Appropriate moisture = check other factors
    • Too wet or too dry = you found the issue

  6. When did you last fertilize?

    • Recently/regularly = not nutrient deficiency
    • Never or many months ago = possible deficiency

  7. How’s the light?

    • Bright location = not light issue
    • Dim location = possible light issue

  8. Are there any pests?

    • Check carefully!
    • Early detection is key

Quick Decision Tree

One or two lower leaves yellowing slowly: → New growth healthy? → Yes = Normal aging, no action needed → No = Check care conditions

Multiple leaves yellowing quickly: → Soil wet? → Yes = Overwatering, let dry out → No = Check next question → Soil very dry? → Yes = Underwatering, water more frequently → No = Check light and nutrients

Yellowing + other symptoms: → Wilting despite wet soil = Overwatering/root rot → Webbing or pests visible = Pest problem → Leggy growth = Insufficient light → Slow growth + pale leaves = Nutrient deficiency

What to Do With Yellow Leaves

Should You Remove Them?

Yes, if:

  • Completely yellow (no green left)
  • Already brown and crispy
  • You prefer the appearance without them
  • Plant otherwise healthy

How to Remove:

  • Cut at base with clean scissors
  • Or gently pull—should release easily when fully yellow
  • Don’t remove partially yellow leaves (still photosynthesizing)
  • Don’t remove more than 1/3 of plant

Can Leave On If:

  • Only partially yellow
  • Prefer to wait for natural drop
  • Want to monitor progression
  • Plant is healthy otherwise

Bottom Line

Normal Aging:

  • ✓ One or two oldest leaves at a time
  • ✓ Slow, gradual yellowing
  • ✓ New growth is healthy
  • ✓ No other symptoms
  • Action: None needed, completely normal!

Problem That Needs Attention:

  • ✗ Multiple leaves yellowing quickly
  • ✗ Upper leaves also affected
  • ✗ Other symptoms (wilting, pests, brown spots)
  • ✗ No healthy new growth
  • Action: Diagnose and correct underlying issue

Most Common Causes of Problem Yellowing:

  1. Overwatering (check soil moisture)
  2. Insufficient light (move to brighter location)
  3. Underwatering (water more consistently)
  4. Nutrient deficiency (begin fertilizing)
  5. Pests (inspect and treat)

Don’t panic if you see a yellow lower leaf or two—it’s often completely normal! But if yellowing is rapid or widespread, investigate care conditions to identify and fix the underlying issue.
