Houseplants are remarkably forgiving — until they’re not. One week everything looks fine, and the next, you’re staring at yellow leaves wondering what went wrong.

Most houseplant problems fall into a few predictable categories and are fixable with TLC and patience. Here’s how to identify what’s happening and what to do about it.

Light Issues: Too Much or Too Little

Light is the foundation of plant health. Get it right, and your plants thrive. Get it wrong, and they’ll let you know.

Signs of Too Much Light

What you’ll see:

• Crispy brown patches on leaves, especially near windows
• Bleached, washed-out, or faded leaf color
• Wilting despite having moist soil
• Scorched or burned leaf edges

What’s happening: Direct sunlight is too intense for the plant. Think of it like a sunburn — the leaves are literally getting damaged by heat and UV exposure.

How to fix it:

• Move the plant a few feet back from the window
• Use sheer curtains to diffuse direct sunlight
• Rotate the plant regularly so all sides get even light
• Consider moving sun-sensitive plants (like ferns or calatheas) to east-facing windows with gentler morning light

Signs of Too Little Light

What you’ll see:

• Stretching, leggy stems reaching toward the light source
• Stopped or significantly slowed growth
• Yellowing leaves, especially on lower or inner parts of the plant
• Loss of variegation (colorful leaves turning solid green)
• Leaning heavily in one direction

What’s happening: The plant is trying to find more light. It’s stretching toward any available source, sacrificing compact growth and leaf production in the process.

How to fix it:

• Move the plant closer to a window (ideally south- or west-facing for bright indirect light)
• Rotate the plant weekly for even growth
• Consider a grow light if natural light is limited
• Prune leggy growth to encourage bushier, healthier regrowth

Just Right: What Healthy Light Looks Like

What you’ll see:

• Steady, balanced growth
• Vibrant, consistent leaf color
• Upright leaves facing the light source (not drooping or reaching)
• New growth appearing regularly during the growing season

Watering Issues: Too Much or Too Little

Watering is where most houseplant problems begin. It sounds simple, but getting it right requires paying attention.

Signs of Overwatering

What you’ll see:

• Yellow or limp leaves (especially lower leaves)
• Mushy, soft, or blackened stems
• Mold or fungus gnats on the soil surface
• Soil that stays wet for days or smells sour
• Root rot (roots that are brown, black, or mushy instead of white and firm)

What’s happening: The roots are sitting in waterlogged soil and can’t access oxygen. They begin to rot, and the plant can’t absorb water or nutrients — even though the soil is soaking wet.

How to fix it:

• Stop watering immediately. Let the soil dry out significantly before watering again.
• Check the roots. Gently remove the plant from its pot. If roots are brown, mushy, or smell bad, trim away the damaged sections with clean scissors.
• Repot in fresh, well-draining soil. Don’t reuse old, waterlogged soil.
• Improve drainage. Make sure your pot has drainage holes and consider adding perlite or orchid bark to the soil mix.
• Adjust your watering schedule. Water only when the top 1-2 inches of soil are dry.

Prevention tip: When in doubt, underwater. It’s much easier for a plant to recover from dryness than root rot.

Signs of Under-watering

What you’ll see:

• Curling, crispy, or shriveled leaves
• Significant drooping or wilting
• Dry, pulling-away-from-the-pot soil
• Browning leaf tips or edges
• Leaves dropping off the plant

What’s happening: The plant is dehydrated. It’s shutting down non-essential functions (like maintaining older leaves) to conserve what little moisture it has.

How to fix it:

• Water thoroughly. Water until it drains out the bottom of the pot, ensuring the entire root ball gets moisture.
• Bottom watering can help. Place the pot in a tray of water and let it soak up moisture from the bottom for 10-15 minutes.
• Check your watering routine. Make sure you’re watering deeply, not just misting the surface.
• Increase humidity if needed. Dry air can cause plants to lose moisture faster. Grouping plants together or using a pebble tray can help.

Just Right: What Healthy Watering Looks Like

What you’ll see:

• Firm, vibrant leaves (not limp or crispy)
• Top 1-2 inches of soil feel slightly damp, not soaking wet or bone dry
• No signs of mold, pests, or root rot
• Consistent, healthy growth

Golden rule: Stick your finger into the soil before watering. If the top inch or two is dry, it’s time to water. If it’s still moist, wait.

When in Doubt, Ask

Houseplant care isn’t one-size-fits-all. If you’re seeing symptoms that don’t match these descriptions, or if your plant isn’t responding to treatment, show a photo to the Sunnyside Gardens crew. Our team can help you troubleshoot and get your plants back on track.
