Storing Geraniums Over Winter: A Simple Guide

As cooler months approach, nurturing your beloved geraniums to see them survive the winter requires meticulous care and adjustment to new conditions. The essence of storing geraniums throughout winter lies in three main elements – appropriate preparation, optimal storage conditions, and regular maintenance. A keen spotlight is lighted on the initial process that involves pruning the geraniums and tackling any evidence of rot or diseases. Subsequently, we shift focus toward understanding the necessary storage environment, encompassing the ideal temperature, humidity, and light settings. Lastly, we underline the importance of routine care during these colder months to prevent diseases, pests, and dehydration, ensuring your geraniums bloom vivaciously when spring arrives.

Preparing Geraniums for Storage

Dive into the colorful world of Geraniums – vibrant perennial flowers that add that extra sparkle to gardens. It’s always a delight to watch these lush green plants blooming with clusters of pink, white, or red flowers from spring to fall. However, to keep them brimming with life through the harsh winter, it’s essential to execute precise winter storage preparations. So let’s get into the practical steps to follow for successfully readying geraniums for winter.

Start by selecting the healthiest geraniums. It’s crucial to make a thoughtful selection based on signs of vitality. Look for plants that are free from diseases, shows a burst of life, and generally appears hearty. These plants stand a better chance of surviving the long winter hiatus.

Next, dig up the geraniums. Do this before the first frost hits, as waiting till the frost arrives could hamper your plants’ survival chances. Carefully lift the plants (root and all), and shake them lightly to remove excess soil. Then, put them into paper bags or hang them upside down in a dark, cool, and well-ventilated area – a basement often works well for this.

Once safely stored, scale back watering. Geraniums are dormant during winter, and overwatering can lead to fatal outcomes, such as root rot. Instead, keep the roots slightly moist. While too much water can drown the roots, keeping them completely dry can cause damage too. Get the balance right with occasional moisture.

Both regular check-ups and pruning are essential. Every 4 to 6 weeks, inspect the plants for any sign of decay or disease. Discard any that have succumbed to rot to prevent it from spreading to other plants. Furthermore, feel free to prune back excessively long or weak stems. It enhances new growth in the subsequent spring season.

Finally, don’t forget the reintroduction phase. About 2 to 3 months before the risk of frost is gone, repot the geraniums in fresh, well-draining soil. Place them in a sunny spot and water slightly. Watch as the miracle of rebirth takes place – your geraniums should start to regrow!

By following these steps, it’s possible to maintain the glory of your geraniums year-round. Rest assured, your time and effort spent preparing geraniums for winter storage will result in colorful blooms to enjoy once again when warmer days return. Happy gardening!

Optimum Storage Condition for Geraniums

Ensuring the Optimal Environment for Winterizing Your Geraniums

The magic and beauty of geraniums can be preserved year-round – even through the fierce chills of winter – with the correct knowledge of their care needs during this dormant season. In this installment, let’s dive deeper into the best conditions for storing these vibrant plants in winter, going past the basics already discussed ranging from selecting healthy geraniums to their reintroduction in the warm sun.

First on the expert checklist is maintaining a consistent temperature. Aim to provide an environment that stays regularly between 45-50 degrees Fahrenheit. These cool temperatures mimic the geranium’s natural winter condition in its Mediterranean homeland. Extreme temperature fluctuations can stress the plants, leading to wilting or even plant death.

Secondly, remember that humidity is a critical factor. Geraniums prefer moderate humidity. It can be tricky to achieve in winter, primarily if the storage space is heated. Invest in a good humidifier to maintain the air moisture level—this aids in preventing leaf drop, a common issue in overly dry conditions.

Light exposure should also not be overlooked. Even though these plants are in a dormant state, they still benefit from a few hours of daylight. Position them near a window that receives diffuse light but bear in mind to guard against direct sunlight; it can dry out your geraniums rapidly, leading to dehydration.

Watering requirements should also be adjusted. You may have already scaled back watering, but take it a step further in winter, ensuring the soil is almost dry before adding more. A good rule of thumb is to water them only once a month. Overwatering at this time triggers rotten roots and encourages fungal diseases.

Lastly, air circulation is an essential aspect. Choose a well-ventilated area or make use of an oscillating fan at low speeds to improve air circulation. This practice reduces the chance of pest infestations, often a significant concern in winter.

Understanding these unique winter needs of geraniums and implementing them helps these beautiful plants to make it through the winter season successfully. By keeping the temperature, humidity, light, watering, and ventilation at optimum, your geraniums can breathe easy, delivering a stunning show of blooms as soon as spring arrives!

Maintaining Geraniums during Winter Storage

Understanding the ins and outs of geranium preservation through the winter can seem daunting, but with the right tools and a touch of patience, these flourishing beauties can be meticulously maintained during their dormant state. We’ve already covered the basics on choosing, storing, and reintroducing your geraniums, but now let’s dive a bit deeper and look into the specific environmental factors that need to be considered.

Managing the temperature

Around your stored geraniums is critical! Consistency is key here. Geraniums are most comfortable with temperatures between 45 to 50 degrees Fahrenheit. Too warm, the plants become distressed, and too cold – they are at risk of freezing. Carefully monitor surrounding temperatures, using a thermometer if needed. This consistency helps geraniums to carry on their dormant state smoothly.


Is another pivotal factor in keeping your geraniums happy through the winter. Keep in mind, these plants don’t like excessive humidity, as it can create a breeding ground for mold and mildew. Rather, they prefer moderate humidity levels. Strive for a setting that has some humidity without being overly damp.


It’s easy to consider neglecting this factor during geraniums’ hibernation period, but it’s fundamental! Striking the balance is essential here, too much light can stimulate growth while complete darkness can deter natural processes. Provide your geraniums with indirect, moderate light, such as ambient light coming in through a window.


While it’s true that you’ll need to reduce watering in the winter as the plants slow down their growth, that doesn’t mean eliminating it! Adjust the watering requirement accordingly. Allow the soil to dry out between waterings. The idea is to provide just enough water to keep the plant alive, taking care not to let the stems shrivel up or dry out.

Air circulation

Last but not least, good air circulation can be a savior in preventing any pest infestations from marring your precious plants’ dormancy. As these plants are now indoors, they can be more susceptible to insects. A spot with good air movement can help in deterring pests, but not so much as to cause the plant to dry out.

Again, it all comes down to balance. Provide your geraniums with the right conditions and they’ll continue to flourish post-winter, providing you with another season of vibrant, colorful blooms that symbolize your care, commitment, and dedication to this wonderful hobby. Look after these factors during the winter and you’ll be giving your geraniums the chance to strut their stuff one more time when spring has sprung!

Ensuring the survival of geraniums throughout winter doesn’t have to be an enigma or a mammoth task. Armed with knowledge about the importance of pruning, the optimal storage conditions, and the significance of regular maintenance, you can ensure your geraniums maintain their robust health despite the harshness of winter. The successful storage of geraniums during winter provides a rewarding and vibrant garden in the spring. So, embrace the winter storage process with confidence, ensuring that your geraniums endure and thrive, ready to delight again in the warmer months.
