Geranium Plant Care: Tips for Bushy Blooms And Healthy Growth

So, why grow geraniums? They’re beautiful, versatile, and pretty darn low-maintenance once you know what you’re doing. Whether you’re a beginner or a seasoned gardener, they add a splash of color and even help with pest control.

 Native to South Africa, they thrive in warm climates and can survive a little neglect. The trick? Giving them just enough love without smothering them. And trust me, I’ve been guilty of over-watering in my early days. Don’t repeat my mistakes!

Fun fact: Geraniums were once believed to repel evil spirits and were commonly planted near homes for protection.

Geranium Benefits

Okay, so let’s talk about why geraniums are worth the effort. Besides being ridiculously easy on the eyes, geraniums have a bunch of benefits:

1. Low Maintenance: You don’t need a green thumb to grow them. I mean, if I can figure it out, anyone can.
2. Repels Pests: Their smell keeps mosquitoes and other annoying pests at bay. I didn’t even realize this until I noticed fewer bug bites after planting them near my patio!
3. Versatility: Geraniums can be grown in pots, hanging baskets, or right in the ground. They’re perfect for adding pops of color anywhere you want.
4. Long Blooming Season: These babies bloom all summer long. It’s like the gift that keeps on giving.

Types of Geranium: Picking the Right One

When I first got into geraniums, I had no clue there were so many varieties. I thought they were all the same! But nope, you’ve got choices, and each type has its own personality.

• Zonal Geraniums: These are your classic, big blooms. They’ve got these funky, dark zones on the leaves, which is why they’re called “zonal.”
• Ivy Geraniums: These are more of a trailing variety, perfect for hanging baskets. Their leaves are glossy and almost waxy, and they spill over the sides in a way that looks like they were made for Instagram.
• Scented Geraniums: Oh man, these smell so good. The leaves give off scents like lemon, rose, or even mint. I love brushing by them just for that burst of fragrance.
• Regal Geraniums: These are the drama queens of the bunch. They’ve got big, showy flowers, but they’re a bit more high-maintenance.
• Hardy Geraniums: If you live in a cooler climate, these are your best bet. They're more rugged and can handle a bit of cold, unlike their delicate cousins.

Geranium Plant Care Tips

Alright, let’s dive into the meat of it. Caring for geraniums isn’t rocket science, but there are some basics you need to know to keep them looking their best.

Light: Geraniums Love the Sun!

If there’s one thing geraniums adore, it’s sunshine. Seriously, don’t skimp on it. They need about 6-8 hours of full sun each day to really thrive. If they’re not getting enough light, you’ll notice the blooms start to get sparse, and no one wants that.

But here’s the thing: too much hot afternoon sun can actually scorch them. In the dead of summer, if you’re in a super hot climate, they might appreciate a bit of afternoon shade.

Soil: Well-Drained or Bust

Geraniums hate soggy roots. I mean, hate it. If you plant them in heavy, compacted soil that doesn’t drain well, they’re gonna start looking sad real quick. Use a well-draining potting mix, and if you're planting them in the ground, make sure the soil isn’t heavy clay.

Tip: If you’re planting them in pots, toss in some perlite or sand to help with drainage. Trust me, your geraniums will thank you.

Watering: Don’t Overdo It!

Here’s where I messed up big time when I first started with geraniums. I thought, “Hey, more water means happier plants, right?” Wrong! Geraniums like their soil to dry out a bit between waterings. So, let the top inch of soil dry out before you give them a drink.

In summer, that might mean watering a couple of times a week, but in cooler months, you can ease off.

Temperature and Humidity: Warm, Not Wet

Geraniums love warmth, but they’re not fans of high humidity. Ideally, they like temps between 65°F and 75°F (18°C-24°C). They’ll survive a bit of a cold snap, but frost will kill them. If you live in an area where winters get chilly, you’ll need to bring them indoors (more on that later).

Fertilizer: Feed Them Right

During the growing season (spring through summer), feed your geraniums every two weeks with a balanced, water-soluble fertilizer. But don’t overdo it—too much fertilizer can cause more leaves and fewer flowers.

Pro tip: Go easy on the nitrogen-heavy fertilizers. They’ll give you big, lush leaves, but at the expense of blooms.

Geranium Plant Care Indoors

If you live in a cooler climate, or just want some greenery inside, geraniums can thrive indoors with a bit of TLC. Make sure they’re in a sunny spot—preferably a south-facing window—and give them a good watering when the soil dries out. Keep an eye out for leggy growth, which usually means they’re not getting enough light.

And here’s a bonus: Indoors, they still act as natural pest repellents. It’s like having a little bodyguard for your other houseplants.

Geranium Plant Care Outdoors

Outdoors, it’s all about placement. Make sure they’re in a sunny spot, and if you’re planting them in the ground, mix in some compost to keep the soil light and nutrient-rich.

When I first started planting geraniums outdoors, I underestimated how much space they need. These guys can spread out! Give them a little breathing room, and they’ll reward you with more blooms.

Geranium Care in Winter

This was a game-changer for me. Instead of tossing your geraniums out when the cold hits, you can actually overwinter them.

Here’s how:

1. Trim them back by about a third.
2. Dig them up, shake off the soil, and store them in a cool, dark place (like a basement).
3. Water them sparingly—just enough to keep the roots from drying out.

Come spring, replant them, and boom—free geraniums for the new season.

How to Make a Geranium Bushy

Ever wonder why some geraniums look all lush and full, while others get spindly and sad-looking? The secret is regular pruning. If you trim your geraniums back regularly, they’ll grow bushier.

I usually trim mine back by about a third every few months, especially after the blooms start to fade. And don’t be afraid to prune aggressively—it actually helps the plant grow back stronger.

How to Care for Geraniums in Pots

One of the best things about geraniums is how well they do in containers. Whether you’ve got a small balcony or just want some patio décor, potted geraniums can bring serious color to any space.

The key here is drainage. Always make sure your pots have drainage holes. I once planted geraniums in a beautiful ceramic pot without checking, and they got waterlogged—goodbye, geraniums. Lesson learned!

Also, potted plants tend to dry out faster than those in the ground, so keep an eye on the soil. If it feels dry an inch below the surface, it’s time to water. And don’t forget to rotate your pots every couple of weeks so all sides get equal sun. Geraniums love basking in the light, and this simple trick will keep them from getting lopsided.

How to Deadhead Geraniums

Deadheading geraniums is a must if you want a continuous show of vibrant blooms throughout the growing season. It encourages new flower growth by directing the plant's energy away from producing seeds and toward making more flowers.

1. Identify Spent Blooms

Look for flowers that have started to fade or wilt. Once the petals begin to lose their vibrant color, they’re ready to be deadheaded. It’s a good habit to check your geraniums regularly to catch spent blooms early.

2. Locate the Stem

Follow the flower stem back to the base where it meets the main stem of the plant. You want to cut the entire flower stem, not just the bloom, as this will prevent the plant from wasting energy on seed production.

3. Snip the Stem

Using a clean pair of scissors or garden shears, snip the stem just above the next set of healthy leaves. Make a clean cut to avoid damaging the plant. Removing the entire stem encourages the plant to produce new blooms from that point.

4. Remove Dead Leaves

While you’re at it, check for any yellowing or dead leaves and remove those as well. This not only improves the plant’s appearance but also prevents diseases and pests from taking hold.

5. Repeat Regularly

Geraniums will keep producing blooms as long as you keep up with deadheading. It can feel like a chore, but trust me—your efforts will pay off with a fuller, more vibrant plant.

Anecdote: I used to be a bit lazy with deadheading, and I wondered why my geraniums stopped blooming by midsummer. Once I started

Common Geranium Mistakes (That I’ve Made!)

I’m not going to lie, I’ve made almost every geranium mistake in the book. Here are a few I’ve learned from:

1. Overwatering: I know I’ve mentioned this, but seriously, I’ve killed more geraniums with too much love (aka water) than anything else. If you’re unsure, err on the side of underwatering.
2. Not Pruning Enough: Letting your geraniums get leggy because you’re afraid to prune them? Don’t be! Regular trimming keeps them full and bushy.
3. Ignoring Deadheading: I used to think deadheading was optional, but it’s really the secret to a longer blooming season. Trust me, the extra effort is worth it.
4. Poor Drainage: Whether they’re in pots or the ground, geraniums need well-drained soil. I learned the hard way that soggy roots lead to sad, droopy plants.

How to Grow Geraniums from Cuttings

Propagating geraniums from cuttings is not only easy but also an economical way to grow more plants. Plus, it’s a satisfying process when you see those first roots appear! Here's how you do it:

1. Choose the Right Time

The best time to take geranium cuttings is late spring or early summer when the plant is actively growing. Though geraniums can be propagated year-round, the warm growing season gives you the best results.

2. Gather Your Tools

Before starting, make sure you have the following:

• A sharp, clean knife or garden shears
• Rooting hormone (optional, but it speeds up the process)
• Small pots filled with well-draining potting soil or a mix of peat and perlite
• A spray bottle for misting

3. Select a Healthy Stem

Choose a healthy, green stem that’s about 4-6 inches long and free from any signs of disease. The stem should have at least two or three leaf nodes (the points where leaves grow out from the stem). A tip I learned: avoid older woody stems—they take longer to root.

4. Make the Cut

Using a sharp, sterilized knife or shears, make a clean cut just below a leaf node. Remove the leaves from the lower part of the cutting, leaving the top set of leaves intact.

If your geraniums have any flower buds, pinch those off too. This ensures the plant focuses on root development instead of flower production.

5. Dip in Rooting Hormone (Optional)

While geraniums root fairly easily, you can speed up the process by dipping the cut end of your stem in a rooting hormone powder. If you don’t have any, don’t worry—your cuttings can still take root without it. But using the hormone can boost success rates.

6. Plant the Cutting

Poke a hole in the pre-moistened potting mix and insert the stem about 1-2 inches deep. Gently firm the soil around the cutting to hold it upright.

7. Water and Wait

After planting the cutting, give it a light misting with water and place it in a bright but indirect light. Avoid direct sunlight during this stage, as it can stress the young cutting. Keep the soil slightly moist, but not soaking wet. A little patience goes a long way—roots should start forming in about 3-4 weeks.

8. Transplant the Rooted Cutting

Once you notice new growth or resistance when you gently tug on the cutting (a sign that roots have developed), it’s time to transplant it into a larger pot or directly into your garden. Make sure to harden off your new plant by gradually exposing it to outdoor conditions if it’s been indoors.

Personal Tip: I’ve had more success when I used smaller pots for the initial rooting stage. Smaller containers prevent the soil from holding too much moisture, which can cause rot. Keep an eye on your cutting, and don’t be disheartened if the first few attempts take time!

Geranium Companion Plants: The Best (and Worst) Neighbors

Geraniums are pretty friendly plants, but they do have some neighbors they pair better with. If you’re planting them in the garden, consider pairing them with:

• Marigolds: They help ward off pests. I swear, my garden became a bug-free zone once I planted these two together.
• Lavender: Not only do they look great side by side, but the scent combo is amazing. Plus, lavender loves similar conditions—lots of sun and not too much water.
• Petunias: They thrive in the same environment and create a stunning contrast with geranium blooms.

On the flip side, avoid planting geraniums near anything that loves tons of water (like ferns or certain types of vegetables). They won’t appreciate their roots being constantly soggy

Common Geranium Plant Problems

Geraniums are tough plants, but they’re not immune to a few common problems. Knowing how to identify and address these issues early can keep your plants healthy and vibrant. Here’s what to watch out for:

1. Yellow Leaves

One of the most common issues with geraniums is yellowing leaves. It can be caused by various factors:

• Overwatering: Geraniums prefer slightly dry soil. If the soil is too wet, it can lead to root rot and yellow leaves. To fix this, reduce watering and ensure proper drainage.
• Nutrient Deficiency: Yellowing can also indicate a lack of nitrogen. Feeding your plants with a balanced fertilizer can help green up the leaves.
• Cold Stress: Geraniums love warm temperatures. If it gets too cold, their leaves can turn yellow and drop off. Move potted geraniums indoors or to a warmer spot.

2. Leggy Growth      

Leggy or spindly geraniums are usually the result of insufficient sunlight. These plants need full sun to grow compact and bushy. If they’re not getting enough light, they stretch out, looking weak and unattractive. To correct this, move them to a sunnier location, and don’t hesitate to pinch back the tips to encourage fuller growth.

3. Wilting

Wilting can be a sign of either underwatering or overwatering. It’s important to check the soil’s moisture level before making any changes. If the soil is bone dry, your plant needs more water. On the other hand, if the soil is soggy, it might be time to let it dry out.

4. Root Rot

Root rot is a more severe issue caused by consistently overwatered, poorly drained soil. A sure sign of root rot is a mushy, brown, or black root system. Unfortunately, if the root rot is severe, it can be hard to save the plant. To prevent root rot, always ensure your geraniums are in well-draining soil and avoid waterlogged conditions.

5. Flower Drop

Geraniums can sometimes experience premature flower drop due to stress. It could be temperature fluctuations, inconsistent watering, or too much fertilizer. Try to keep the growing conditions steady—especially watering schedules—and avoid fertilizing too heavily, as over-fertilizing can lead to flower drop.

Geranium Diseases

Like most plants, geraniums can attract a few unwelcome pests and diseases. Here’s a rundown of the most common ones and how to deal with them.

1. Geranium Rust

One of the most frustrating issues I’ve encountered with geraniums is geranium rust. This fungal disease is sneaky—it starts with small, yellow or white spots on the underside of the leaves. If left unchecked, these spots turn into rust-colored pustules. I learned the hard way that this can spread quickly, leading to defoliation.

The solution? First, remove any affected leaves immediately and dispose of them (don’t compost!). You’ll also want to reduce overhead watering and ensure good airflow around your plants. Using a fungicide that targets rust can help keep it under control.

To prevent geranium rust from coming back, keep your plants in well-ventilated areas and avoid getting the leaves wet during watering. Keeping your garden tools clean also helps stop the spread of the disease from plant to plant. Trust me, the last thing you want is for rust to take over your entire geranium collection!

2. Botrytis Blight

Botrytis blight, or gray mold, is another fungal disease that can affect geraniums, especially in damp conditions. It appears as gray, fuzzy mold on the flowers or leaves and can cause them to rot. Prune away infected parts of the plant and increase airflow around your geraniums to prevent this disease.

3. Bacterial Blight

Bacterial blight is a more serious problem that causes brown, water-soaked spots on the leaves, stems, and flowers. It spreads easily through water, so avoid getting the foliage wet when watering. Remove any infected parts immediately and disinfect your tools to prevent further spread.

Geranium Pests 

1. Aphids

Aphids are small, soft-bodied insects that love to suck the sap from young geranium shoots. If you notice curled or distorted leaves, check for these tiny pests on the undersides of the leaves. They can cause stunted growth and damage to the plant. To get rid of aphids, wash them off with a strong stream of water or use insecticidal soap.

2. Spider Mites

Spider mites are nearly invisible to the naked eye, but you’ll know they’re around if you see tiny webs on your geraniums or notice that the leaves have a speckled, bleached appearance. These pests thrive in hot, dry conditions. Combat them by regularly misting your plants to increase humidity and using a miticide if needed.

Tip: I’ve had great success with a DIY insecticidal soap made from dish soap and water. Just make sure to test it on a small section of the plant first!

3. Whiteflies

Whiteflies are another sap-sucking pest that can infest geraniums. They’re tiny, white, moth-like insects that flutter around the plant when disturbed. These pests can weaken the plant by feeding on its sap. Yellow sticky traps can help catch adult whiteflies, and insecticidal soap works well for managing an infestation.

Recap: Why Geraniums Deserve a Spot in Your Garden

So, why grow geraniums? They’re beautiful, versatile, and pretty darn low-maintenance once you know what you’re doing. Whether you’re a beginner or a seasoned gardener, they add a splash of color and even help with pest control.

The key to successful geranium plant care? Don’t overwater, give them plenty of sun, and prune regularly. Follow these tips, and you’ll have healthy, happy geraniums that thrive all season long. Plus, you’ll get to enjoy their beauty indoors or out, year after year.

FAQ

How do you get geraniums to keep blooming?

To keep geraniums blooming, deadhead spent flowers regularly and ensure they get enough sunlight—at least 6 hours a day. Fertilize once a month during the growing season and avoid overwatering. Giving them a slight prune encourages more flowers.

Do geraniums like shade or sun?

Geraniums love full sun but can tolerate partial shade, especially in very hot climates. In cooler regions, aim for at least 6-8 hours of direct sunlight daily to get the best blooms.

How do you take care of potted geraniums?

Potted geraniums thrive in well-draining soil and need watering only when the top inch of soil is dry. Place them in a sunny spot, and deadhead regularly to encourage continuous blooming. Fertilize monthly during the growing season with a balanced fertilizer.

How long do potted geraniums last?

With proper care, potted geraniums can last for many years. They may need to be overwintered indoors in colder climates, but as long as you provide the right conditions, they’ll come back year after year.

Do geraniums come back every year?

In warmer climates (zones 9-10), geraniums can be perennial and come back year after year. However, in cooler climates, they are treated as annuals or brought indoors for overwintering.
