9 Geranium Growing Mistakes That You Can Avoid

9 Geranium Growing Mistakes That You Can Avoid

Sharing is caring!

Geraniums, with their vibrant blooms and lush foliage, are a gardener’s delight. As an expert gardening blogger, I’ve seen my fair share of geranium-growing successes and mistakes.

The key to flourishing geraniums lies not just in what we do right, but also in avoiding certain pitfalls.

Let’s dive into some common geranium growing mistakes and learn how to sidestep them for a stunning display.

1. Overwatering: The Root of Trouble

Water is vital for plants, but too much can be just as harmful as too little. Overwatering is one of the most common mistakes I see in geranium care. These plants prefer a ‘drink-and-dry’ approach. Overly moist soil leads to root rot, a notorious killer of geraniums.

The trick is to allow the soil to dry out slightly between waterings. If your geranium’s leaves are yellowing or its stems are becoming soft, it’s time to evaluate your watering routine.

2. Ignoring Light Requirements: A Shady Mistake

Geraniums love the sun – they thrive in it! A common misstep is placing them in areas with insufficient light. They require at least six hours of direct sunlight to bloom profusely. Without enough light, you’ll notice leggy growth and sparse blooming.

If you’re growing geraniums indoors, a south-facing window is ideal. For outdoor gardens, ensure they’re not overshadowed by taller plants. Remember, a sun-starved geranium is a sad geranium.

3. Neglecting Soil Health: The Foundation of Growth

Soil isn’t just dirt; it’s the foundation of your plant’s health. Geraniums prefer well-draining soil that’s rich in organic matter. A mistake often made is using heavy, clay-like soil that retains too much moisture. This can lead to root issues and poor growth.

Amend your soil with compost or a well-balanced potting mix designed for container plants. A healthy soil means a happy geranium!

4. Forgetting to Fertilize: Starving Your Blooms

A common oversight in geranium care is forgetting about fertilization. Geraniums are heavy feeders, especially during their active growing and blooming phases. The absence of regular feeding can lead to lackluster blooms and weak growth.

I recommend using a balanced, water-soluble fertilizer every two to four weeks during the growing season. Be careful not to over-fertilize, as this can lead to salt buildup in the soil and damage the plant. Think of fertilization as a balanced diet for your geraniums – essential for their vibrant display and overall health.

5. Overlooking Pest Management: An Unseen Threat

Even the most attentive gardener can overlook the subtle signs of pests on their geraniums. Common culprits like aphids, whiteflies, and spider mites can turn your thriving plants into struggling ones.

These tiny invaders often go unnoticed until significant damage has occurred. Regularly inspecting your geraniums for pests is crucial.

Look under leaves and along stems for any signs of infestation. If you do find pests, treat them promptly with an appropriate, plant-safe insecticide or natural remedy like neem oil. Preventative measures, such as maintaining good air circulation around the plants, can also help keep pests at bay.

Remember, early detection and intervention are key to managing these unseen threats.

6. Neglecting Pruning: Letting Chaos Reign

Pruning is an essential aspect of geranium care that’s often neglected. Without regular pruning, geraniums can become leggy and overgrown, leading to a decrease in blooms and an unkempt appearance.

Pruning encourages bushier growth and more flowers. It’s important to regularly deadhead, or remove spent blooms, and trim back overgrown stems, especially in the early spring.

This not only keeps your geraniums looking tidy but also diverts energy to new growth and blooms. Don’t be afraid to give your plants a good trim; geraniums are quite resilient and respond well to pruning. Think of it as a refreshing haircut for your plants, stimulating healthier and more vibrant growth.

7. Incorrect Winter Care: A Cold Misstep

A pivotal mistake with geraniums, especially in colder climates, is incorrect winter care. These plants are not frost-hardy and need protection from cold temperatures. One common error is leaving geraniums outside during winter, expecting them to survive the frost. Instead, bring them indoors before the first frost hits.

Place them in a cool, bright location, and reduce watering to a minimum, just enough to prevent the soil from completely drying out. Some gardeners prefer to store the bare-root plants in a cool, dark place after removing all the soil and trimming the foliage.

Whichever method you choose, remember that winter care is crucial for ensuring your geraniums bounce back beautifully in spring.

8. Ignoring Container Requirements: A Confining Error

When growing geraniums in containers, a common mistake is ignoring the specific needs of potted plants. Geraniums in containers require more attention than those in the ground.

The first misstep is often choosing the wrong size or type of container. Geraniums need room for their roots to spread, so a container that’s too small can stunt their growth. Ensure that your pot has adequate drainage holes to prevent waterlogging, which can lead to root rot.

9. Overlooking Seasonal Adjustments: Failing to Adapt

The final common mistake in growing geraniums is failing to make seasonal adjustments in their care. Geraniums’ needs change with the seasons, and overlooking this can hinder their growth and blooming potential.

During the intense heat of summer, geraniums may need more frequent watering and some afternoon shade to prevent stress and wilting. Conversely, in the cooler months, they require less water and benefit from being moved to a spot where they can receive more sunlight.

Another aspect often missed is adjusting fertilization schedules. In the growing season, regular feeding supports robust growth and flowering. However, as winter approaches, it’s advisable to reduce or stop fertilizing altogether, as the plants enter a dormant phase.

Adapting your care routine to the changing seasons is crucial for maintaining healthy, vibrant geraniums year-round. Remember, gardening is not just about following a set of rules, but about observing and responding to the needs of your plants as they grow and change through the seasons.
