How to Plant Geraniums

Whether you’re starting from seed or purchasing ready-to-plant geraniums from your local garden center, planting geraniums is a simple and rewarding task. Here’s a step-by-step guide to help you get started.

Choosing the Right Geraniums for Your Garden

Before you start planting, it’s essential to choose the right type of geranium. There are several varieties available, and each has its unique features and growing needs. Some of the most popular types include:

• Zonal Geraniums: These are the classic choice, known for their compact, upright growth and brightly colored blooms in shades of red, pink, and orange. Zonal geraniums thrive in sunny locations and well-drained soil.

• Ivy Geraniums: With their trailing vines and smooth, ivy-like leaves, ivy geraniums are perfect for hanging baskets or container gardens. They love the sun and produce lovely flowers similar to zonal geraniums, but with a more cascading look.

• Regal Geraniums: If you’re after large, eye-catching blooms, regal geraniums are the way to go. Their bold flowers and slightly aromatic foliage make them an excellent choice for container gardens or as indoor plants.

• Scented Geraniums: For a fragrant touch in your garden, consider adding scented geraniums. With leaves that release scents like rose, lemon, or mint, these geraniums add both beauty and aroma to your space.

Choosing the Right Location

Geraniums love the sun and are happiest when planted in a spot that gets at least 6 hours of direct sunlight each day. Whether you’re planting them in flower beds or pots, make sure the location has plenty of exposure to the sun. While geraniums can tolerate partial shade, they won’t bloom as vigorously in low-light conditions, so aim for sunny spots to get the most out of these beauties.

Preparing the Soil

Good soil is key to healthy geraniums. These plants thrive in well-draining soil that’s rich in organic matter. If your garden soil is heavy or clay-like, improve drainage by adding organic compost or perlite. This will help ensure the roots aren’t sitting in water, which could lead to rot. Geraniums are not too picky about soil pH, but they prefer a slightly acidic to neutral pH (around 6.0–7.0).

Planting Geraniums

Planting geraniums is straightforward:

1. Dig the Hole: Dig a hole that is deep enough to accommodate the plant’s root ball. You want the top of the root ball to sit level with the soil surface.

2. Remove the Plant from Its Pot: Gently remove the geranium from its pot and carefully loosen the roots if they’re circling around the root ball.

3. Place the Plant: Position the plant in the hole and backfill with soil, making sure it’s secure.

4. Water Well: Water the plant thoroughly right after planting to help the roots settle in. Keep the soil moist but not soggy.

For starting geraniums from seed

When starting geraniums from seed, patience is the most important factor, as it can take 12 to 16 weeks to see a flowering plant.

1. Sow seeds indoors 10-12 weeks before the last spring frost

2. Use seed-starting mix in clean containers with drainage

3. Plant seeds ¼ inch deep and keep the soil consistently moist

4. Maintain temperatures between 70-75°F for germination

5. Provide bright light once seedlings emerge

6. Transplant outdoors after the danger of frost has passed

Container Planting Tips

Geraniums do wonderfully in containers, making them a great option for patios, balconies, or small gardens. Here’s how to plant geraniums in pots:

• Choose the Right Pot: Pick a pot with drainage holes to prevent water from accumulating at the bottom. This helps prevent root rot.

• Use Well-Draining Potting Mix: Choose a high-quality potting mix that drains well. You can even mix in some perlite or sand to increase drainage.

• Space Them Properly: Make sure your pot is big enough for the geranium to grow comfortably. If you’re using a container for multiple plants, space them 12–18 inches apart to allow proper airflow and growth.

Caring for Geraniums

While geraniums are fairly low-maintenance, they still need a little love and attention to thrive. Here are some key care tips to help your plants flourish:

Watering

Geraniums don’t like to sit in water, so make sure the soil drains well. Water them thoroughly when the top inch of soil feels dry, but avoid letting them sit in standing water. If you’re growing geraniums in containers, make sure the pot has adequate drainage to prevent root rot. Overwatering can be just as harmful as underwatering, so aim for a balanced watering routine.

Fertilizing

Proper nutrition encourages abundant flowering in geraniums without promoting excessive foliage growth.

Geraniums benefit from regular fertilization. Once your geraniums are established, feed them with a balanced fertilizer every 4–6 weeks. A fertilizer with a 20-20-20 ratio (containing equal amounts of nitrogen, phosphorus, and potassium) will encourage strong growth and vibrant blooms. Be sure to avoid over-fertilizing, as this can cause excessive foliage growth at the expense of flowers.

Container specimens benefit from a water-soluble fertilizer applied at half-strength every 2-3 weeks. Always water plants thoroughly before and after fertilizing to prevent root burn.

Pruning and Deadheading

Regular deadheading and occasional pruning keep geraniums looking their best while encouraging continued blooming.

Deadheading is simple, you just pinch off any flowers that look weak or have turned brown. Usually, a gentle tug using your thumb and forefinger will easily remove the dead flower stalk.

Perform this maintenance weekly during the growing season to:

• Encourage new bloom production

• Prevent seed formation, which diverts energy from flowering

• Maintain a neat appearance

• Reduce disease issues from decaying flowers

More substantial pruning helps maintain plant shape and vigor:

1. Remove leggy stems by cutting just above a leaf node

2. Pinch growing tips on young plants to encourage branching

3. Trim back by one-third in late summer to refresh tired plants

4. Remove any diseased or damaged growth promptly

Potting and Repotting

Geraniums do well in pots, but they may need to be repotted every 1 to 2 years as their roots grow. When repotting, choose a container that is 1–2 inches larger than the current one. Fresh, well-draining potting mix is essential to help the roots spread and grow comfortably. If your geraniums seem root-bound (when the roots are tightly coiled around the pot), it’s definitely time for a new home.

Seasonal Care Guide

• Spring: In the spring, it’s time to wake up your geraniums! Fertilize and water regularly to encourage new growth and vibrant blooms.

• Summer: Geraniums will be in their prime during the summer. Keep up with watering, deadhead spent flowers to promote continuous blooming, and keep an eye out for pests.

• Fall: As the weather cools, you can bring your container geraniums indoors to extend their season. If you live in a colder climate, you can also overwinter geraniums inside as houseplants.

• Winter: In winter, you can reduce watering for indoor geraniums. They still need some sunlight, so place them near a sunny window. If you’re growing geraniums as annuals, you can treat them as a seasonal crop and replant fresh ones the next year.

Common Problems and Easy Solutions for Geraniums

Geraniums are hardy, but they can face a few common challenges. Here’s how to troubleshoot and keep your plants looking their best:

Yellowing Leaves

If your geranium’s leaves are turning yellow, it could be a sign of overwatering or nutrient deficiency. To fix this, ensure the soil drains well and apply a balanced fertilizer. If overwatering is the issue, adjust your watering schedule to allow the soil to dry out between waterings.

Pest Infestations

Geraniums can attract pests like aphids, whiteflies, and spider mites. Keep an eye on your plants and treat any infestations promptly with organic insecticidal soap or neem oil. Regularly inspect the plants and remove any pests you find by hand.

Lack of Flowers

If your geraniums are not blooming, they may not be getting enough sunlight or could be overfertilized. Make sure they receive at least 6 hours of direct sun daily and avoid using too much high-nitrogen fertilizer, which encourages foliage growth over flowering.

Cold Damage

Geraniums are sensitive to cold and will struggle if temperatures drop below 50°F. If you live in a region with cold winters, bring container geraniums indoors for the winter. If they’re planted in the ground, treat them as annuals or dig them up and overwinter them indoors.

How to Keep Geraniums Over the Winter

If you live in an area where temperatures drop below 50°F in the winter, you’ll need to take steps to overwinter your geraniums. While geraniums are perennials in tropical climates, they are typically grown as annuals in cooler regions. However, with the right care, you can keep them alive over the winter and enjoy them again next year.

1. Bring Them Indoors: Before the first frost hits, dig up your geraniums from the garden and bring them indoors. Choose a sunny windowsill or a bright room with lots of light.

2. Prune Back: Trim back any leggy or unhealthy growth to prepare your geranium for the indoor environment. Removing dead or damaged stems will help the plant focus on new growth in the spring.

3. Water Sparingly: During the winter months, geraniums go dormant and don’t need as much water. Water them sparingly, just enough to keep the soil slightly moist. Avoid letting the soil dry out completely.

4. Provide Light: Geraniums still need light, even in winter. Place them in a location where they’ll receive at least 4–6 hours of bright sunlight daily. If natural light is limited, you can use grow lights to supplement.

5. Temperature: Keep your geraniums in a room that stays between 55°F to 65°F. They will not tolerate freezing temperatures, so make sure to keep them away from cold drafts or windowsills that get too chilly.

Creative Uses for Geraniums

Geraniums are more than just a pretty face—they’re also versatile in the garden! Here are a few creative ways to use them:

• Hanging Baskets: Geraniums make excellent hanging basket plants, where their trailing vines can spill over the edges.

• Borders and Flower Beds: Use geraniums as part of a mixed flower bed or as a border plant to add vibrant color.

• Indoor Plants: Geraniums also thrive indoors, making them a perfect addition to sunny windowsills or patios.

• Scented Geraniums: Some geranium varieties have fragrant leaves that can be used in making homemade potpourri, essential oils, or even for culinary purposes like flavoring desserts or teas.

FAQs About Geraniums
