If your houseplants look dull, droopy, or crispy, you might not be giving them enough water. While overwatering gets most of the blame, underwatering can be just as damaging. This guide will help you understand what happens when plants don’t get enough water, how to recognize the signs, and how to keep your plants properly hydrated.
Why Underwatering Is a Problem
Water keeps your plant’s cells firm, supports nutrient transport, and powers photosynthesis. When soil dries out completely and stays that way, roots begin to die back and lose their ability to take up water at all.
Underwatered plants often appear wilted or brittle, but the damage happens below the surface first. Dry soil pulls away from the sides of the pot, and roots shrink and harden, making it harder for them to absorb moisture even when you finally water again.
Signs You Are Underwatering
It’s easy to confuse underwatering with other issues, but these are the most common symptoms:
-
Leaves are dry, crispy, or curling at the edges
-
Soil is pulling away from the pot and feels bone-dry
-
The plant feels unusually light when lifted
-
Growth has slowed or stopped completely
-
Leaves are dropping suddenly
-
Water runs straight through the pot when you finally water it (a sign roots have dried out)
If several of these signs sound familiar, it’s time to change your watering routine.
Common Causes of Underwatering
1. Inconsistent Watering Schedule
Life gets busy, and many plant owners simply forget to water. Tropical houseplants, in particular, need consistent moisture to stay healthy.
2. Wrong Potting Mix
Some soils dry out too quickly. A mix that contains too much sand or bark might not retain enough moisture for tropical plants. Try a balanced potting mix like Maya’s Growing Mediums, designed to hold moisture without staying soggy.
3. Pot Too Small or Too Porous
Small pots or unglazed terracotta dry out much faster than larger or glazed containers. If your plant needs frequent watering, it may be time to repot into a slightly larger pot.
4. Too Much Sun or Heat
Direct sunlight, hot windowsills, and dry indoor air can cause moisture to evaporate faster than the plant can absorb it.
5. Watering Too Lightly
Many people sprinkle a little water on top instead of watering thoroughly. This causes the top layer to get wet while the lower roots remain completely dry.
How to Fix an Underwatered Plant
-
Water Deeply and Slowly
Pour water evenly over the soil until it begins to drain from the bottom of the pot. Wait a few minutes and water again if necessary to rehydrate the root zone fully. -
Soak if Severely Dry
If the soil has pulled away from the pot, submerge the entire pot in a sink or bucket of water for about 10–15 minutes. This helps the soil absorb water evenly. -
Trim Damaged Leaves
Remove completely dry or brown leaves so the plant can focus on new growth. -
Check the Pot and Soil
If the soil dries out within a day or two, it may be too loose or fast-draining. Repot with a mix that better suits your plant’s moisture needs. -
Create a Consistent Watering Routine
Use a moisture meter to track when your plant actually needs water instead of guessing. (Insert link to Urbane Eight’s moisture meter here.) -
Use the Right Tools
A watering can with a narrow spout helps direct water to the soil instead of the leaves, ensuring even hydration. (Insert link to Urbane Eight’s watering cans here.)
How to Prevent Underwatering
-
Check soil moisture regularly — don’t rely on appearance alone
-
Establish a watering routine based on your home’s light, temperature, and humidity
-
Use high-quality potting mix that holds moisture evenly
-
Group plants together to create a more humid microclimate
-
Adjust your watering frequency during hot or dry months
-
Use self-watering pots or water-retaining granules for high-maintenance plants
Final Thoughts
Underwatering is easy to fix once you recognize the signs. Most plants prefer evenly moist soil — not bone dry and not constantly wet. By paying attention to your plant’s appearance, checking the soil before watering, and using the right tools, you can find the perfect balance.
