How to Grow Geraniums in Pots

Pelargonium, more commonly known as geraniums, are perennials any gardener can spot from a mile away. What makes them so wonderful is that they can thrive in a wide range of living conditions — did you know geraniums love to grow in pots, too?

Geraniums are the perfect plant to put into pots to enhance the curb appeal of your house. Hang them off the balcony, put them directly in the garden, or place them around your deck. Then, watch them come back year after year.

These popular and bright flowers are easy to grow, have plenty of foliage, and are a lovely splash of color to add to any garden. Learn how you can grow your own geraniums in pots, how to help them thrive, and what to do to prepare them for the following year’s growth.

Materials You Will Need

  • Planter pot of your choice
  • Gardening or potting soil
  • Trowel
  • Garden shears or cutters
  • Gardening gloves, if you want!

Step-by-Step Instructions

Step 1 – Select Your Pot

Geraniums are not picky when it comes to where they are planted — gardening pots, repurposed pots, or practically any object in the right shape can act as a vessel for your plants. What you choose to plant your geraniums in is completely up to you. However, it is important to keep in mind that geraniums require an area of around 10 inches to grow to their full potential. Your plant’s pot should also have a good drainage system with holes on the bottom so excess water can evacuate the soil if needed. As long as your pot has enough space and drainage opportunities, select any color, style, size, or texture of the pot you prefer!

Step 2 – Find Your Geraniums

Geraniums are perennial plants that are available in garden or hardware stores throughout the growing season. Because of their wide selection of colors and how easy they are to grow, you will always be able to find a geranium plant or seeds.

When selecting a geranium plant to grow in a pot, the only thing you need to decide is how many and what color. You can select geraniums in a wide array of colors, including red, pink, white, orange, yellow, purple, and even some that are multi-colored (like the Regal Geranium). Find the color that speaks to you, and move on to step three!

Step 3 – Plant Your Geraniums

Now that you have the geranium of your choosing, it is time to plant! Using a pre-made potting/garden soil mixture, or your own combination of compost and loose soil, fill up your pots. It is important to make sure your soil is not too dense, as this can lead to root rot. You must also ensure that wherever you place your geranium pots, they receive plenty of sun throughout the day.

To plant a pre-grown geranium, use your garden trowel to dig out a space that is roughly the same size as the container in which you purchased it. If you are planting multiple geraniums, allow about 12 inches between each plant for the best growth results.

If you are planting geraniums from seed, begin growing your seedlings indoors in smaller pots. Plant the seeds two to three inches apart from one another and about ¼ of an inch down. Geranium seedlings are a test of patience, as they can take about 15 weeks to grow and should be seeded as early as February. Once they have been nurtured to full plants, you can repot them into a larger pot. But don’t put them outside just yet! Begin to acclimate them to the outdoors after the last frost, bringing the plants indoors each evening. After about a week, your plants are ready to be left outdoors.

Step 4 – Care for Your Geraniums

Now that your geraniums are securely planted in their new home, there is very little required of you. The only thing your geraniums need is routine watering and deadheading. Water your geranium pots at least once a week (or more if you live in a hot climate). For those living in locations with plenty of precipitation, check your geraniums before watering! Too much moisture in the soil may cause the plant to suffer. You will be able to tell if your geraniums are getting too much water if the leaves of the plant begin to turn yellow.

The other thing you can do to help your geraniums is to deadhead to make room for new growth. Deadheading is the removal of any dead flowers or stems that are no longer blooming. One of the reasons gardeners love geraniums is that once deadheaded, flowers are quick to grow again!

Step 5 – Prepare for the Year Ahead

When the growing season is done and your geraniums are no longer producing flowers, it is time to prepare them for the season to come. Use your garden shears or cutters to cut off the geranium plant stems and dead flowers. It is recommended to trim the entire plant so that only a few inches of the main stems remain above ground. Doing this will promote new and healthy growth in the next growing season!

To Sum Up

Geraniums are an ideal plant to grow in pots and place in various spots around your home or garden. All you need to do is find a well-draining pot and plant your geraniums in healthy potting or gardening soil. Once they are planted, water them regularly, taking care not to overwater them. When your geranium flowers start to wilt and brown, deadhead the plant to promote new growth.

Geraniums are a simple and easy plant to take care of, and when given the love they need, they will reward you with colorful flowers all summer long!
