Proper Watering Techniques for Houseplants

At Grey heron, we get a lot of plant care questions—and most revolve around one thing: watering. It’s easy to overdo or underdo it, so here’s your go-to guide for keeping plants hydrated just right.

Hard vs. Soft Water

Not all water is created equal. Many homes use water softeners, which add salt to reduce minerals. Unfortunately, this salt builds up in soil and harms plants over time.

Tip: Use hard water or untreated tap water for your plants.
Test at home: If soap lathers easily, your water is soft.

Top vs. Bottom Watering

We recommend watering from the top—just like we do in the greenhouse. This flushes out salts and minerals that build up in the soil.

Exception: Fuzzy-leaved plants (like African Violets) can be bottom watered briefly, but never leave pots sitting in water for long.

Tip: Water from the top until it drains out the bottom. Empty excess from saucers.

Deep vs. Shallow Watering

Avoid shallow, frequent watering (like a cup a day). It only wets the topsoil and leaves deeper roots dry.

Tip: Water deeply so the entire root zone is hydrated. Always water until it runs through the pot’s drainage hole.

Summer vs. Winter Watering

Your plant’s needs change with the seasons. Less sunlight in winter means slower growth—and less water needed.

Tip: In summer, water more often. In winter, stretch out your watering schedule (sometimes every 2–3 weeks).

How to Know When to Water

Different plants have different needs. Use your finger to check moisture—insert it an inch deep into the soil.

Tip: Water only when the soil feels dry to the touch, and always refer to plant-specific care instructions on tags or labels.

Skip the Gimmicks

Ice cubes on orchids or misting succulents? These so-called “watering hacks” can do more harm than good. Cold water shocks tropicals, and misting doesn’t hydrate roots.

Tip: Stick to deep, thorough watering when your plant needs it.

Diagnosing Watering Issues

Overwatering and underwatering often look the same. If your plant is drooping, losing leaves, or fading in color, check the roots:

• Dry, brittle roots = underwatered

• Soft, mushy roots = overwatered

Tip: Gently remove the plant from the pot to inspect the root system and adjust care accordingly.

Common Signs of Water Stress

• Brown or yellow leaves

• Wilting or limp growth

• Dry, brittle foliage

• Sudden leaf drop

• Dull or faded colors

• Fungus gnats (often from overwatering)

Bottom Line: Listen to your plants. Learn their individual needs, water deeply, adjust with the seasons, and skip the shortcuts. With the right approach, your plants will thrive!
