How Often to Water Geraniums?

Geraniums are a popular flowering plant that can add color and life to any garden or indoor space. However, it can be tricky to determine how often to water them. Too much water can lead to root rot, while too little water can cause the leaves to wilt and fall off. In this article, I will share my expert advice on how often to water geraniums, so you can keep your plants healthy and vibrant.

First, it’s important to consider the location of your geraniums. If they are planted in a well-draining soil mix and receive plenty of sunlight and airflow, they will likely require more frequent watering than those in a dense, shady area. Additionally, outdoor geraniums may need to be watered more often during hot, dry weather, while indoor plants may need less water during the winter months when the air is drier.

When it comes to watering geraniums, it’s essential to find a balance between keeping the soil moist and not over-saturating it. As a general rule, you should water your geraniums when the top inch of soil feels dry to the touch. However, be sure to check the soil moisture level frequently, as changing weather conditions can impact the rate of water absorption. In the next section, I’ll provide more specific guidance on how to water your geraniums based on the type of plant and environment.

How Often Should You Water Geraniums?

As an experienced gardener, I’m often asked how often geraniums should be watered, and it’s a question that doesn’t have a one-size-fits-all answer. The frequency of watering depends on various factors such as soil, temperature, humidity, sunlight, and the type of container you are growing them in.

Here are a few tips to help you decide when to water your geraniums:

  1. Check the soil moisture regularly – Geraniums prefer well-drained soil, so it’s essential to ensure the soil isn’t waterlogged, which can cause root rot. You can dip your finger into the soil about an inch deep to check the moisture level. If the soil feels dry, it’s time to water, but if it’s still moist, wait for a few more days before watering again.
  2. Watch for signs of dehydration – If the geraniums are wilting or the leaves are yellowing, it’s a sign that they need water. However, it’s also crucial not to overwater, which can lead to root rot and other fungal diseases.
  3. Consider the temperature and humidity – During hot weather, you may need to water your geraniums more frequently than during cooler weather. Similarly, if you’re growing geraniums in a low-humidity environment, they may need more water than those in a humid environment. However, avoid splashing water on the leaves, as it can lead to fungal disease.
  4. Choose the right container – The type of container you use can also affect the watering frequency. Clay pots and hanging baskets tend to dry out faster than plastic or metal containers, which means they may need more water. However, this also depends on the size and location of the container.

In summary, geraniums prefer moist, well-drained soil and should be watered when the soil is dry. However, avoid overwatering, which can lead to root rot and fungal diseases. The frequency of watering depends on several factors such as soil, temperature, humidity, and the type of container, so it’s essential to monitor these conditions regularly. With these tips, you can keep your geraniums healthy and thriving.

Here is the section titled “Tips for Watering Geraniums in Different Seasons”:

Tips for Watering Geraniums in Different Seasons

Proper watering is crucial for the health of geraniums, and the amount of water they need might change depending on the season. Here are some tips to help you water your geraniums correctly in different seasons:

Watering Geraniums in Spring

As the weather warms up in the spring, your geraniums may start to grow more rapidly, producing new foliage and flower buds. This growth requires more water. Water your plants thoroughly once a week, and make sure that the soil is moist but not waterlogged. Always allow the soil to dry out between watering to prevent root rot.

Watering Geraniums in Summer

Summer can be a challenging season for geraniums, as the heat can quickly dry out the soil. Watering in the early morning or late in the day helps reduce water loss through evaporation. Daily watering may be necessary during extreme heatwaves, but be careful about overwatering, which can also harm your plants.

Watering Geraniums in Fall

As the daylight hours shorten and the temperatures start to drop in the fall, slow down on watering. Geraniums naturally start to go dormant in the fall, and less water is needed to sustain them. Water once every 10 days or so, making sure the soil remains slightly moist but not saturated.

Watering Geraniums in Winter

Geraniums are susceptible to root rot in the winter if the soil is too wet. Water them only when the soil dries out completely, usually every few weeks. This helps ensure that the plant’s roots are not sitting in water, which can cause them to rot.

By following these season-specific tips for watering geraniums, you can ensure a healthy and thriving plant for every season.

Types of Soil and Containers for Geraniums

When it comes to growing healthy geraniums, choosing the right soil and container is just as important as watering them regularly. Here are a few things to keep in mind:


Geraniums require well-draining soil to prevent root rot. A good potting mix for geraniums should contain perlite or vermiculite, or a mix of both. These materials improve drainage and aeration, ensuring that roots have enough oxygen.

Adding some sand or peat moss to the potting mix can also aid drainage. However, too much sand can make the soil dry out too quickly, while too much peat moss can lead to soil compaction and poor drainage.


Choosing the right container size is crucial for the health of your geraniums. If the container is too small, the roots will become cramped, and the plant won’t thrive. On the other hand, if the container is too big, the soil will stay too wet, which can lead to root rot.

As a general rule, a container that is 1-2 inches larger in diameter than the plant’s nursery pot is a good size. A 6- or 8-inch container is typically enough for a small geranium, while a larger plant may require a 10- or 12-inch container.

When choosing a container, make sure it has drainage holes at the bottom to allow excess water to escape. If you’re planting your geranium in a decorative container without drainage holes, consider using a plastic liner with drainage holes to prevent water from accumulating at the bottom.

In conclusion, choosing the right soil and container for your geraniums is essential for their overall health and growth. Opt for well-draining soil with perlite or vermiculite and choose a container that is just the right size. With the right care, your geraniums will reward you with beautiful flowers all season long.
