Getting to Know Geraniums: A Brief Introduction

Geraniums are popular plants that can add beauty and color to any garden or indoor space. They are known for their vibrant flowers and distinct, pleasant scent. These versatile plants come in a variety of types and varieties, making it easy to find one that suits your preferences and needs.

Common types of geraniums include zonal geraniums, ivy geraniums, and scented geraniums, each with unique characteristics and growing requirements. Zonal geraniums are the most common type and are known for their large, round leaves with dark bands. Ivy geraniums have trailing stems and are ideal for hanging baskets or window boxes. Scented geraniums, as their name suggests, have fragrant leaves that can range from lemon to mint.

Meanwhile, popular geranium varieties include the Maverick, the Tango, and the Designer series, among others. These varieties come in a wide range of colors, from reds and pinks to purples and whites.

Once you have selected your geranium plant, the next step is to learn how to care for it properly. The following sections will provide you with the information you need to keep your geraniums healthy and thriving.

Finding the Perfect Spot: Geranium Plant Placement

Geranium plants thrive in the right environment, so selecting the right location for them is crucial. When it comes to sunlight, geraniums need an adequate amount to bloom beautifully. Ideally, they should receive six hours of direct sunlight each day. However, geraniums can still survive in partial shade or dappled sunlight as long as they get enough light.

Indoor geraniums should be placed near a window or under grow lights to ensure they receive enough sunlight. On the other hand, outdoor geraniums should be planted in spots where they can get the right amount of sun and shade. For instance, you can place them under trees or near other tall plants to provide shade during the hottest parts of the day.

In addition to sunlight, consider other factors like temperature and humidity. Geraniums prefer temperatures between 60-75°F, so avoid placing them in excessively hot or cold areas. They also thrive in areas with moderate to high humidity levels, which you can increase by grouping them together or using a humidifier.

Quenching Their Thirst: Geranium Watering Tips

Proper watering is vital to keep geraniums thriving. Here are some essential tips to keep your plants hydrated:

1. Watering Amount

The key to watering geraniums is striking a balance between not enough and too much. Overwatering can cause root rot, while underwatering can result in wilting and stunted growth. As a general rule, water geraniums when the top inch of soil feels dry to the touch. Use enough water so that it drains out of the bottom of the pot, but be sure to empty any excess water from the drainage tray to avoid waterlogging.

2. Watering Frequency

The frequency of watering depends on several factors such as temperature, humidity, and the size of the pot. Generally, geraniums need to be watered about once a week, but adjust accordingly to the needs of your plants. During hot, dry weather, or if your geraniums are in a smaller pot, they may require more frequent watering. On the other hand, during the cooler months, or if they are in a larger pot, they may need less water.

3. Avoid Common Mistakes

Some common mistakes to avoid when watering geraniums include:

  • Don’t water from above, as wet foliage can lead to leaf spot and other fungal diseases.
  • Don’t let the soil dry out completely. This can cause the roots to become parched and can lead to the death of the plant.
  • Don’t allow the plant to sit in standing water, which can lead to root rot.

By following these watering tips, your geraniums will be healthy and happy. As with any plant, it’s important to pay attention to your geraniums and adjust your watering routine as needed.

Feeding Time: Geranium Fertilizer Guide

Fertilizing geraniums is crucial for their growth and blooming potential. However, choosing the right fertilizer and applying it at the right time is essential. Here are some tips for feeding your geranium plants:

Choosing the right fertilizer

When it comes to selecting a fertilizer for geraniums, it is important to choose one that is specifically formulated for flowering plants. Look for a fertilizer with high levels of phosphorus, which is essential for blooming.

Another option is to use an all-purpose fertilizer with balanced levels of nitrogen, phosphorus, and potassium. This will promote overall growth and health of your geranium plant.

Fertilizing schedule

It is recommended to fertilize geranium plants every four to six weeks during the growing season, which typically starts in spring and lasts until fall.

However, it is important not to over-fertilize your geraniums, as this can lead to excessive foliage growth and fewer blooms.

Application method

The best way to apply fertilizer to your geranium plants is to mix it with water and apply it to the soil. Avoid applying fertilizer directly to the leaves or flowers, as this can burn the plant.

You can also use a slow-release fertilizer, which will gradually release nutrients over time. This is a convenient option if you are busy and do not have time to fertilize your plants frequently.

With these tips in mind, your geraniums will be well-fed and blooming beautifully all season long.

Shaping and Trimming: Geranium Pruning Tips

Pruning and deadheading are essential tasks for maintaining healthy and blooming geraniums. Pruning removes dead or damaged stems, promotes branching, and prevents legginess. Deadheading removes spent blooms, encourages new growth, and prolongs blooming.

When to Prune Geraniums

The best time to prune geraniums is in early spring before new growth appears. This is when they are still dormant, making it easier to see which stems need to be cut back. You can also prune geraniums in late summer or early fall after the peak blooming period has ended. Avoid pruning geraniums during the winter or early spring when they are not actively growing.

How to Prune Geraniums

To prune geraniums, use a clean and sharp pair of pruning shears or scissors. Cut back the stem to just above a node, which is where leaves emerge from the stem. Make a clean cut at a slight angle to prevent water from accumulating on the stem and to promote healing. For leggy geraniums, you can prune back up to one-third of the plant’s height to encourage branching.

How to Deadhead Geraniums

To deadhead geraniums, use your fingers or a pair of scissors to snip off the spent blooms just above a leaf or node. Avoid leaving any stubs or cutting too close to the main stem. Deadheading should be done regularly throughout the growing season to promote continuous blooming.

Remember to clean your pruning shears or scissors with rubbing alcohol before and after use to prevent the spread of disease. Also, be sure to dispose of any diseased or infested plant material properly.

Battling the Bugs: Geranium Pest Control

Geranium plants are generally low-maintenance and pest-resistant, but even the healthiest plants can fall victim to certain pests. Here are some common types of geranium pests and how to control them:

Common Geranium Pests

Pest Description
Aphids Tiny, pear-shaped insects that suck sap from plants and cause distorted growth.
Spider Mites Small arachnids that spin fine webs and suck sap from leaves, causing yellowing and browning.
Whiteflies Tiny flies that feed on plant sap and cause yellowing and stunting.
Thrips Slender, brown insects that suck plant sap and cause distorted growth and discoloration.
Mealybugs Soft-bodied insects that produce white, cottony masses on leaves and stems and suck plant sap.

Note: Other occasional geranium pests to watch out for include scale insects, caterpillars, and snails/slugs.

Prevention and Control Strategies

The best defense against geranium pests is prevention. Here are some simple strategies to keep pests at bay:

  • Inspect plants regularly and remove any dead, damaged, or diseased foliage.
  • Isolate new plants for a few weeks to make sure they are not infested with pests.
  • Ensure proper drainage to prevent root rot and fungal diseases.
  • Clean and sterilize gardening tools, pots, and containers before use.
  • Avoid over-fertilizing, as this can attract pests.

If your geraniums do come under attack, there are several options for control:

  • Handpicking: This involves physically removing pests by hand and disposing of them. This is best for small infestations and larger pests like caterpillars and snails.
  • Biological control: This involves introducing natural predators, such as ladybugs or lacewings, to the garden to eat the pests. This can be effective but requires careful research and planning.
  • Chemical control: This involves using insecticides or pesticides to kill pests. This should be a last resort and should only be used according to the product label instructions.

Note: Always wear gloves when handling pesticides and follow all safety precautions.

Preparing for Winter: Geranium Cold Weather Care

As the weather turns colder, it’s time to start thinking about preparing your geranium plants for winter. Proper care during the winter months will ensure healthy growth and blooming the following season. Here are some essential tips for geranium cold weather care:

Bringing Geraniums Indoors

If you live in an area with freezing temperatures, it’s a good idea to bring your geranium plants indoors before the first frost. Choose a bright location in your home with plenty of sunlight, such as a south-facing window. Keep in mind that indoor air is often drier than outdoors, so make sure to monitor your plants’ watering needs closely and avoid placing them near sources of hot or cold air.

Winter Watering

During the winter months, geraniums require less water as they enter a state of dormancy. Wait until the top inch of soil is dry before watering your plants, and be careful not to overwater. Over-watering can lead to root rot, a common problem during winter dormancy.

Storing Geranium Plants

If you have limited space or want to keep your geraniums out of sight during the winter, you can store them in a cool, dark place where they will remain dormant until spring. Before storing, remove any dead or damaged leaves and cut back the stems to one-third of their original length. Place them in a paper bag or wrap them in newspaper to prevent them from drying out. Check on them occasionally and mist them lightly with water if they appear too dry.

By following these tips, you can ensure your geranium plants survive the winter and come back healthy and blooming the following season.

Multiplying Your Blooms: Geranium Propagation Techniques

Geranium plants are known for their beautiful blooms and versatility in gardens and homes. If you want to expand your collection or share your plants with friends and family, geranium propagation is an easy and affordable option. Here are some techniques to help you propagate your geraniums successfully.

Method 1: Propagating from Cuttings

One of the most popular methods of geranium propagation is by using stem cuttings. Here’s how:

  1. Select a healthy stem from your geranium plant, measuring at least 4-6 inches in length.
  2. With a sharp, sterile scissors or knife, make a clean cut just below a node (the point where leaves attach to the stem).
  3. Remove the leaves from the bottom half of the stem, leaving a few at the top.
  4. Dip the cut end of the stem in rooting hormone. This step is optional but can increase your chances of success.
  5. Place the cutting in a pot filled with well-draining soil and water thoroughly.
  6. Cover the pot with a plastic bag or dome to create a mini greenhouse effect.
  7. Place the pot in a warm, bright location, but out of direct sunlight. Keep the soil moist but not waterlogged.
  8. After a few weeks, check for roots by gently tugging on the stem. If it resists, roots have formed. If it pulls out easily, give it more time.
  9. Once rooted, remove the cover and move the new plant to its own container, or transplant it outdoors once the weather permits.

Method 2: Propagating by Division

Another method for geranium propagation is by dividing the plant. This is particularly useful if your geranium has outgrown its container or is showing signs of root congestion. Here’s how:

  1. Carefully remove the geranium plant from its pot or garden bed.
  2. Gently shake off any excess soil to reveal the roots.
  3. Using a sharp, clean knife or scissors, divide the plant into sections, each with its own set of roots and stems.
  4. Trim back the foliage to reduce the amount of stress on the divided plant.
  5. Plant each new section in its container or garden bed, and water thoroughly.
  6. Keep the newly divided geraniums in a warm, bright location, but out of direct sunlight until they have adjusted and are growing well.

By using these methods, you can easily multiply your geraniums and enjoy their beautiful blooms in more areas of your garden or home. Remember to be patient and allow time for your new plants to flourish.

Sailing Smoothly: Geranium Troubleshooting Tips

Geraniums are generally easy to care for, but sometimes problems can arise. Here are some common issues you may encounter and how to solve them:

Yellowing Leaves

If your geranium’s leaves are turning yellow, it may be a sign of overwatering. Check the soil’s moisture level and cut back on watering if it’s too wet. Yellowing leaves can also indicate nutrient deficiency, so consider fertilizing with a balanced fertilizer.

Root Rot

Root rot is a fungal infection caused by overwatering or poor drainage. If your geranium’s roots are brown and mushy, it may have root rot. To remedy the situation, repot the plant in fresh, well-draining soil. Be sure to let the soil dry out between waterings and avoid overwatering in the future.

Pest Infestation

Common pests that can affect geraniums include spider mites, aphids, and whiteflies. To prevent and treat pest infestations, regularly inspect your plants and remove any affected leaves or insects. You can also use natural pest control methods such as neem oil or insecticidal soap.

No Blooms

If your geranium isn’t blooming, it may be due to insufficient sunlight. Make sure it’s getting enough light by placing it in a sunny spot or providing supplemental grow lights. Lack of nutrients can also be a culprit, so consider fertilizing with a bloom-boosting fertilizer.


If your geranium is wilting, it may be due to underwatering or overheating. Check the soil’s moisture level and water as needed. If the plant is in direct sunlight, it may be getting too hot, so move it to a shadier spot.

By addressing these common problems, you can help your geraniums thrive and flourish.
