How to Grow Geranium

Growing geraniums, whether you’re starting from seed or transplanting mature plants, can be a gratifying experience.

Below, we’ll explore the steps and considerations to grow your geranium plants successfully.

  • Select the right spot: Geraniums are fairly adaptable and can thrive in full sun, partial sun, or light shade. However, they generally prefer a spot that gets morning sun and afternoon shade, if possible.
  • Prepare the soil: Geraniums prefer soil that drains well as they do not tolerate soggy conditions. The soil should be enriched with compost or a slow-release fertilizer to provide the necessary nutrients for the plants.
  • Choose the right pot: If you’re planting geraniums in pots, make sure the pot has good drainage. The size of the pot should be appropriate for the variety of geranium you’ve chosen.
  • Planting: Plant your geraniums about 8 to 12 inches apart. They should be planted at the same depth as they were in their original pot.
  • Watering and care: Water your geraniums deeply once the soil begins to feel dry. Keep a watch for any signs of disease or pest infestation. Regularly remove dead leaves and spent blooms to encourage new growth.

Where to Grow Geranium

The location of your geraniums can play a significant role in their growth and blooming.

Here are some considerations for where to grow your geranium plants.

  • Outdoor garden: Geraniums can be a great addition to outdoor flower beds or borders. They prefer a location that gets at least six to eight hours of sunlight.
  • Pots and containers: Geraniums grow very well in pots and containers, making them an excellent choice for balconies, patios, or indoor growing. Make sure the container provides adequate drainage.
  • Hanging baskets: Certain types of geraniums are perfect for hanging baskets. These can be hung outdoors or indoors near a sunny window.
  • Window boxes: Geraniums can be a vibrant addition to window boxes, especially in urban settings where garden space might be limited.
  • Greenhouse cultivation: For those living in colder climates, geraniums can be grown in a greenhouse, which provides a controlled environment that can be adjusted according to the plants’ needs.

How to Plant Geranium Plants

Geranium plants, also known as pelargoniums, are popular choices for adding vibrant colors and delightful fragrances to your garden.

Whether you’re a seasoned gardener or a beginner, growing geraniums can be a rewarding experience. Here are some steps to help you successfully plant geraniums:

  • Choose a suitable location: Geraniums thrive in full sun, so select a spot in your garden that receives at least six to eight hours of sunlight daily. Ensure that the soil drains well to prevent waterlogged conditions, which can harm the plants.
  • Prepare the soil: Before planting, prepare the soil by loosening it with a garden fork or spade. Remove any weeds or rocks and incorporate organic matter, such as compost or well-rotted manure, to improve the soil’s fertility and drainage.
  • Select healthy plants: Purchase healthy geranium plants from a reputable nursery or garden center. Look for plants with sturdy stems, lush foliage, and no signs of pests or diseases.
  • Dig the planting holes: Dig holes that are slightly larger than the root balls of the geranium plants. Space the holes about 8 to 12 inches apart, depending on the variety.
  • Plant the geraniums: Gently remove the geraniums from their containers and place them in the prepared holes. Ensure that the top of the root ball is level with or slightly above the soil surface. Backfill the holes with soil and press it gently around the roots to eliminate air pockets.
  • Water thoroughly: After planting, water the geraniums thoroughly to settle the soil around the roots. Provide enough water to moisten the soil but avoid overwatering, as geraniums prefer slightly dry conditions.
  • Mulch and maintain: Apply a layer of organic mulch, such as wood chips or straw, around the base of the plants to conserve moisture, suppress weeds, and regulate soil temperature. Monitor the plants regularly, checking for signs of water stress, pests, or diseases.

How to Care for Geraniums

To keep your geranium plants healthy and thriving, proper care is essential.

Follow these tips to ensure the best care for your geraniums:

  • Watering: Geraniums prefer moderate water levels, so water them when the top inch of soil feels dry to the touch. Avoid overwatering, as it can lead to root rot. Water the plants at the base to prevent foliage and flowers from getting wet, as wet leaves can be susceptible to diseases.
  • Fertilization: Feed geraniums regularly with a balanced, water-soluble fertilizer formulated for flowering plants. Follow the instructions on the fertilizer package for the correct dosage and frequency. Avoid excessive fertilization, as it can result in lush foliage but fewer blooms.
  • Deadheading: Remove faded flowers regularly to promote continuous blooming and prevent seed production. Pinch or cut off the spent blooms just above a leaf node or stem junction.
  • Pruning: Trim back leggy or overgrown stems in early spring or after the main blooming period to maintain compact and bushy growth. Cut the stems just above a leaf node to encourage branching.
  • Pest and disease control: Keep an eye out for common pests such as aphids, spider mites, and whiteflies. Treat any infestations promptly with appropriate organic or chemical controls. Monitor the plants for signs of diseases such as powdery mildew or bacterial leaf spot, and take necessary measures to prevent their spread.
  • Winter care: In regions with frosty winters, geraniums are typically treated as annuals. However, you can overwinter them indoors by taking cuttings or digging up the plants and potting them. Place them in a bright location with temperatures between 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius) and reduce watering.

By following these care guidelines, you can enjoy a stunning display of colorful geranium blooms and fragrant foliage in your garden.

Remember to observe your plants closely and adjust your care routine as needed to ensure their optimal health and beauty.

How to Prune Geranium Plants

Gardening is not just a hobby, it’s a creative art form where plants are your canvas and pruning shears your paintbrush. And when it comes to Geranium plants, they’re the Vincent Van Gogh of the plant world. But even a masterpiece can use a little touch-up now and then. Here is where pruning comes into play. It not only keeps your geranium looking spruce and neat, but also promotes the growth of those fabulous blooms.

  • Know when to prune: The ideal time to prune geraniums is in late fall or just before spring. This gives the plant a fresh start for its blooming season.
  • Use clean, sharp tools: Before pruning, make sure your pruning shears are clean and sharp to avoid spreading disease or causing unnecessary damage to the plant.
  • Remove dead or diseased parts: The first step is to get rid of any diseased or dead stems. These do not contribute to the plant’s growth and can attract pests.
  • Trim back excessively long stems: Look for any stems that seem out of proportion with the rest of the plant. Cutting these back will help the plant maintain a pleasing shape.
  • Cut above a leaf node: When pruning, make your cut just above a leaf node. This is where new growth will sprout.
  • Thin out crowded areas: If certain areas of the plant are overcrowded with stems and leaves, don’t hesitate to thin them out. This promotes better air circulation, reducing the risk of disease.
  • Consider the desired shape: While pruning, always keep the desired shape of your plant in mind. The goal is to encourage a bushier plant with more blooms.

How to Propagate Geranium

Nothing brings more joy to a gardener than successfully propagating a beloved plant. If the geranium holds a special place in your heart, why not multiply that joy? Propagation, though it might sound complicated, is just a fancy term for making more plants from the ones you already have. And guess what? Geraniums are perfect candidates for this. Here are some steps you can take to propagate your geranium plant:

  • Select a healthy stem: Begin by choosing a robust, healthy stem from your geranium plant. It should be about 4-6 inches long and ideally, should not have any flower buds.
  • Cut the stem: Use a clean, sharp tool to cut the selected stem just below a leaf node. This is where new roots will form.
  • Remove lower leaves: Strip the lower leaves from the stem. This reduces moisture loss from the cutting and directs the plant’s energy towards root development.
  • Let it dry: Allow the cut end of the stem to dry for a few hours or even overnight. This allows the cut to form a protective “callus” which can help prevent rotting.
  • Plant the cutting: Insert the cut end of the stem into a small pot filled with a well-draining soil mix. Water the soil thoroughly.
  • Maintain the right conditions: Place the pot in a location with bright, indirect light and maintain a consistent temperature of around 70°F (21°C).
  • Keep the soil moist: Water the soil regularly to keep it moist but be careful to avoid overwatering.
  • Wait for roots to develop: In a few weeks, the stem will develop roots and can be transplanted to a larger pot or directly to your garden.

Pests and Diseases

No matter how much care we take of our green companions, pests and diseases can sometimes sneak in, uninvited.

It’s like they say, ‘Every garden has its weeds’. Geraniums are no exception.

Here are some of the common pests and diseases that affect geranium plants:

  • Aphids: These small, sap-sucking insects can cause the leaves of your geraniums to curl and become distorted. You can usually spot them on the underside of leaves. If you see aphids, you can try washing them off with a strong jet of water or use an insecticidal soap or neem oil.
  • Botrytis Blight: This is a fungal disease that causes the geranium’s flower buds and leaves to become covered with a gray, moldy coating. It typically occurs in cool, wet conditions. To control it, remove and dispose of infected parts of the plant and avoid watering the plant from above.
  • Bacterial Leaf Spot: This disease causes brown, water-soaked spots to appear on the geranium’s leaves. As the disease progresses, the spots may become surrounded by a yellow halo. Infected leaves will eventually yellow and fall off the plant. The best defense against bacterial leaf spot is to prevent it. Water your geraniums at the soil level and give them plenty of room for air circulation.
  • Whiteflies: These are small, white insects that are often found on the undersides of leaves. They can cause yellowing and stunted growth. Whiteflies can be tough to control, but insecticidal soaps, neem oil, or beneficial insects like ladybugs can help.
  • Root Rot: If your geranium’s leaves are wilting and turning yellow for no apparent reason, you might be overwatering. When the plant’s roots sit in water for too long, they can rot and the plant can die. If you suspect root rot, you may need to repot the plant in fresh, well-draining soil.

Remember, prevention is always the best cure.

Regular inspection of your geranium plants can help detect these pests and diseases early, giving you the best chance of controlling them.

Always ensure that your plants are not overcrowded, have plenty of sunlight, and are watered properly.

These simple steps can go a long way in keeping your geraniums healthy.
