Keeping houseplants healthy and thriving starts with one of the most essential aspects of plant care: watering. While it may seem as simple as pouring water into the soil, many plant parents make common mistakes that can lead to overwatering, underwatering, or even plant disease. We’re going to walk you through everything you need to know to water your houseplants the right way, ensuring they stay happy and healthy!

Understanding Your Plant’s Water Needs
Each plant has unique watering needs based on factors such as:
- Plant Type – Some plants, like succulents and cacti, require infrequent watering, while tropical plants need more.
- Size of the Plant and Pot – Larger plants and pots hold more soil and moisture, while smaller plants dry out faster.
- Season and Climate – Most plants need more water during warm months (active growing times) and less during colder seasons.
- Humidity Levels – If your home is dry, your plants may need more frequent watering, while high humidity can reduce the need for frequent watering.
The Best Watering Techniques
You’re going to find lots of different people with thoughts on a variety of different watering techniques. But, if you ask me, the classic top watering is the best! I’ve tried all the techniques from bottom watering to water pulling, and nothing is as easy and straight forward as watering into the potting mix.
There are a few different option for top watering, depending on the size of the plant (and whether you can move the plant or not). For plants that are hard to move, you can use a watering can, making sure there is a drip tray to catch the water. If you can move the plants, putting them in a sink or the bathtub can be a great option, as you’re not only watering, but rinsing the leaves to clean as well. To ensure your houseplants are properly watered, follow these best practices:
1. Check the Soil Before Watering
One of the easiest ways to determine if your plant needs water is by checking the potting mix:
- Stick your finger about one to two inches into the soil. If it feels dry, it’s time to water.
- If the soil still feels moist, wait a few more days before checking again.
- Use can also use a moisture meter for a more precise reading. I like this one from a small female owned business (selling on Amazon).
2. Water Thoroughly but Not Excessively
When watering your plants, be sure to do so thoroughly, allowing water to soak into the potting mix and reach the roots. However, avoid overwatering, as this can lead to root rot. A good rule of thumb is:
- Water all around the surface of the potting mix.
- Water until you see excess water draining from the bottom of the pot.
- Always use pots with drainage holes to prevent standing water.
- If water runs straight through and out the drainage hole quickly, your plant may need a deeper soak.
3. Use the Right Type of Water
While tap water works fine for many plants, some are sensitive to chemicals like chlorine and fluoride. Here are some alternative water options:
- Filtered or distilled water – Ideal for sensitive plants like spider plants and calatheas.
- Rainwater – A natural, mineral-rich option that plants love.
- Let tap water sit out for 24 hours to allow chlorine to evaporate before watering.
4. Water at the Right Time of Day
The best time to water houseplants is in the morning. This gives plants time to absorb moisture before the temperature rises, reducing the risk of mold or fungal growth overnight.
5. Adjust Watering Based on the Season
- Spring and Summer: Plants are actively growing and need more frequent watering.
- Fall and Winter: Growth slows down, so plants need less water. Overwatering during this period is a common mistake.

Common Watering Mistakes to Avoid
Many plant parents struggle with either overwatering or underwatering their plants. Here are some signs of each:
Signs of Overwatering:
- Yellowing leaves
- Mushy, black, or brown roots
- Fungus gnats around the soil
- Wilting despite wet soil
Signs of Underwatering:
- Dry, crispy leaves
- Soil pulling away from the pot’s edges
- Wilting due to dehydration
The Bottom Line
Watering your houseplants the right way is all about balance. By understanding your plant’s needs, checking the soil regularly, and avoiding common mistakes, you can keep your indoor jungle thriving. Remember, when in doubt, it’s better to underwater than overwater, as you can always add more moisture but can’t take it away once the roots are too saturated.
Now that you’re equipped with the best watering techniques, your plants will thank you with healthy growth and vibrant leaves!
