Watering in Winter: Less Is Not Always Better

As the temperature drops and daylight fades, it's easy to assume that plants need less water during the winter. After all, they're not actively growing, and the soil seems to stay damp for longer. However, this common belief can lead to serious problems for your beloved indoor and outdoor plants.

Avoiding Common Watering Mistakes in Winter

a. The Risks of Underwatering

One widespread mistake gardeners make in winter is drastically reducing the amount of water they give their plants. While plants may need less water than during the growing season, their water needs don't simply disappear. Underwatering can lead to dry, cracked soil, wilting, and even the death of your plants.

b. Spotting the Signs of Underwatering

Identifying underwatering can be tricky, as the symptoms can be similar to those of winter dormancy. Look for leaves that appear dull, curled, or crispy, and check the soil – if it's bone dry several inches down, it's a clear sign your plants need more water.

c. The Importance of Checking Soil Moisture

Relying only on the surface of the soil can be misleading. Use the "chopstick test" to check deeper soil moisture levels by inserting a clean, dry wooden skewer or chopstick into the potting mix. If it comes out clean and dry, it's time to water.

Adapting Your Watering Routine for Winter

a. Factors to Consider

When deciding how much to water your plants in winter, think about the types of plants, the size and material of the pots, the presence of heating sources, and the overall humidity in your growing environment. Succulents, for example, may need even less water than other houseplants during this period.

b. Frequency and Technique

As a general guide, water indoor plants every 10-14 days, allowing the soil to partially dry out between waterings. For outdoor plants, check the soil moisture weekly and water as needed to keep the soil slightly damp (but not waterlogged). When watering, make sure to thoroughly soak the soil to encourage deep root growth.

c. Using Lukewarm Water

Avoid using very cold water, as this can shock the roots. Instead, use room-temperature or slightly warm water to match the soil's natural temperature and prevent stress.

Maintaining Hydration and Humidity

a. Humidity Trays and Misting

Low indoor humidity can make it harder for plants to stay hydrated in the winter. Combat this by using humidity trays or regularly misting the foliage to create a more favorable environment.

b. Adjusting for Heating Sources

If you have space heaters, fireplaces, or other heating sources that dry out the air, be sure to water your plants more often. Plants near these heat sources may need more frequent watering to prevent the soil from drying out too quickly.

Conclusion

Watering your plants correctly during the winter is crucial for their health and survival. By understanding their changing needs, adjusting your techniques, and closely monitoring soil moisture, you can ensure your indoor and outdoor plants thrive even in the coldest months. Remember, less is not always better when it comes to winter watering.
