Geraniums should be planted in window boxes, tubs, hanging baskets, or other big pot containers with the recommended soil mixture. Each container has to drain well. The potting soil should be very organic and well-drained. Garden loam, peat moss, coarse sand, or perlite can all be used in equal amounts to create an excellent mixture. Commercial soil mixtures that have been expertly made may also be adequate. Before you locate one that works well for your specific growth conditions, you might need to try a few.
Watering: Make sure your plant has enough moisture by checking on it daily. Geraniums benefit from the soil drying out a little bit in between waterings. Each time you water, use enough water so that some runs off the bottom of the container. Only apply water when necessary, checking the soil’s moisture level to a depth of 4 to 6 inches.
For container-grown plants, soluble or slow-release fertilizers work best. Fertilize your plants every two months from March to October. Reduce the amount of fertilizer as necessary if plants are being cultivated indoors during the winter or in areas with poor light levels. Before applying fertilizer, make sure the soil is moist and follow the label’s instructions.
Light & Temperature: Geraniums need bright light to remain in bloom all year long. Geraniums grow best on windowsills with a south or west orientation, particularly in the winter. Artificial light is appropriate if there isn’t enough strong natural light in the house. The plants might provide satisfactory results if they are positioned 12 inches beneath a 40-watt, daylight-cool fluorescent bulb for 16 hours per day. Ideal temperatures are between 55 and 70 oF at night and between 65 and 70 oF during the day. Place geraniums away from extreme temperatures and drafts.
How are geraniums maintained indoors?
Once the roots have established, new top growth appears. Rooting might take one to four weeks, depending on the type of plant, light, and temperature. To keep the pots from drying out if you set them in a south window with direct sunlight, you might wish to loosely cover them in a clear plastic bag. Yellowing leaves typically result from overwatering or too cold of a climate.
The plants in their original containers or the ones you brought inside from your outside beds will be substantially smaller once you have taken cuttings from them. Take out any dead branches, brown or yellow leaves, flowers, or flower buds. Place them in a warm, well-lit area with modest water. You might want to take another round of cuttings in late winter or early spring depending on your needs and those of your friends.
For them to grow and bloom indoors, they require at least four hours of daily direct sunlight at regular room temperature. While they are actively growing, water them sparingly, making sure the potting mix is moist but never waterlogged. Between waterings, let the top half inch of the soil dry out. When there are signs of growth, apply a diluted 20-20-20 soluble fertilizer every three to four weeks.
For many years, I’ve kept ‘Shone Helena,’ a magnificent salmon-pink geranium, in my sunroom, where it blooms for most of the winter.
How long can geraniums be grown indoors?
One of the most dependable types of garden flowers is the geranium (Pelargonium spp.). Around the world, they are grown as indoor plants, as garden annuals in USDA plant hardiness zones 2 through 8, and as perennials in zones 9 through 11. If given the right care, a common geranium can live for 40 years or longer. The most frequent causes of geranium death are overwatering or underwatering, insects or illness, and cold snaps. They might eventually grow long and unsightly, at which point they should either be replaced or removed.
Location
Geraniums enjoy the sun and don’t mind being drenched in it over extended periods of time. Put them there if your room has a window that faces south or west. Geraniums need exposure to direct sunlight to develop and bloom, even when cultivated indoors.
Soil
Remember that the correct soil is essential! Be careful not to fill the drainage holes with earth. Use potting soilless. Use soil that is loamy and well-drained instead of garden dirt.
Watering
The most crucial step is now, and it determines whether your geranium plant will live or die. Geranium doesn’t need routine watering because it is a drought-tolerant plant. Only water the soil when it feels dry. Do not overwater!
Temperature
Don’t put your geranium plants in places that are too hot, too cold, or drafty. If a room is warm, geranium adapts to it effectively. But the ideal temperatures are between 65 and 70 degrees Fahrenheit during the day and 55 degrees Fahrenheit at night.
Can indoor geraniums be grown outside?
Depending on the health and age of your plant and the potting mix, you may never need to add fertilizer.
Years ago, I neglected to fertilize the geraniums I had in numerous planters by a drafty west-facing window. After the first few years, when the roots began to grow out of the drainage holes, I did transplant them to larger flower pots and provided fresh potting soil at such time, and it was enough to maintain the floral power.
The usual advice is to use a 20-20-20 liquid fertilizer made for potted flowers if you so choose. Observe the directions on the packaging. Before the busy spring and summer growing seasons, fertilize the soil.
Grow Outdoors Again
Geraniums can be grown year-round indoors or outdoors after the last frost until early fall (before the first frost).
They certainly like living outdoors, and it’s wonderful to keep plants alive this way for many years, but there is always a risk of bringing bugs or diseases back home when they return.
If you do want to give them a summer vacation outside, adhere to these hardening off requirements for plants. “Hardening off” is just a term for progressively acclimating plants to outdoor growth environments so they can adapt well and avoid extreme heat, light, or cold.
Bring Inside as Houseplants
You can bring your potted geraniums (Pelargoniums) indoors for the winter if you have space for them in a sunny place.
While they require sunlight, they thrive in temperatures between 55 and 65 °F (12-18C). I have tremendous luck keeping the air around them a touch colder than the rest of the home with a west-facing window that is slightly drafty.
Dig Up and Repot if Desired
To make sure they are content, healthy, and bug-free, some preparation is needed.
- Before the first frost, dig up and container your geraniums if they are in the ground.
- If they are already in pots, you can repot them if you want, but first perform a rigorous pruning and a bug inspection (see below).
- Trim any extremely long roots or any unkempt root balls before potting.
- Put flowering plants in containers using potting soil made for them.
Hard Prune
- Cutting back the entire plant by between one-third and half is a usual recommendation.
- Any dead, broken, moldy, sick, or diseased pieces should also be taken out.
- If the plant is otherwise good and healthy, you can try keeping any buds or blossoms even though this harsh pruning is ultimately ideal.
Provide Full Sun
Make sure to give geraniums a lot of sunlight to encourage blossoming. A full day of four to six hours of sun will work wonders! Give your potted plants exposure to the south and west for profusion of blossoms.
Deadheading
Geraniums must be deadheaded in order to bloom all summer. To encourage the plant to produce new blooms, remove the spent flowers. To concentrate the plant’s energy on growing new flowers, cut off fading blooms and stems.
Don’t Grow in Large Pots
When growing geraniums, be careful not to choose pots that are wider than 7-8 inches. With enough soil held in place and a healthy plant that will continue to bloom, this size is ideal.
Remove Sick and Yellow leaves Regularly
Regularly remove the dead and yellow foliage to keep the plant looking tidy and to direct its energy toward growing new blossoms.
Apply High Potash Fertilizer
Feed geraniums a 9-6-12 mix to keep them blooming more. The high potassium concentration aids in photosynthesis by supplying nutrients evenly to every area of the plant. Dosage and directions should be found on the label.
Apply all-purpose liquid fertilizer that has been diluted to a fourth of its strength every 4-5 weeks while the plant is growing as well.
Water Only When the Soil is Dry
Keep the soil dry; geraniums are more susceptible to damage from overwatering than from underwatering. Remember to water when the topsoil feels a little dry to the touch. Ensure the container includes drainage holes as well.
Are geraniums healthy indoor plants?
Pelargonium species, which come in pots, make great indoor plants that may be grown all year round. They normally become available in March through June, and if given enough light inside the house, they will bloom continuously. There are several fresh varieties, like vining and hanging basket cultivars. They are available in many different types of containers and at varying stages of development.
How frequently ought I to water my house geraniums?
- Difficulty of Care: Easy to Moderate
- The brightest environment with a few hours of morning or evening sunshine is optimal for geraniums. Lack of this kind of light can cause weak health in plants and possibly plant mortality.
- As long as you check for pests (Aphids, Slugs & Vine Weevils on the leaf, with the latter’s larvae in the soil, too), specimens sold outdoors in garden centers are still acceptable to come indoors. Make sure to give a sunny, bright area to lessen the impact of environmental shock and unexpected flower loss.
- In the heat of the sun, geraniums absorb moisture very quickly, therefore it’s crucial to frequently hydrate your specimen. Between waterings, let the top third dry out; in the fall and winter, cut back a little. In the spring and summer, we’d say once every five to seven days is acceptable.
- Depending on the season, fertilize with a fertilizer labeled for houseplants every two to four weeks. While the plant is in bloom, you can replace this feed every two weeks with “Tomato Food” or “Flowering Plant” fertilizer, both of which contain high potassium levels that are great for controlling flowering.
- Every two years, repot in the spring using a potting mix labeled “Houseplant” and the next-largest pot with drainage holes.
- Since geraniums are generally evergreen and are not susceptible to frost, expect little to no leaf loss during the fall and winter months!

How are geraniums maintained indoors during the winter?
Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mold.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shriveled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Why are the geraniums in my pots dying?
No matter how skilled a gardener is, planting geraniums will always present certain basic issues. We’ve investigated pretty much everything that may go wrong with your geraniums, and in this piece, we’ll share some useful advice with you!
Geranium growers most frequently run into issues with bacterial or fungal illness and incorrect irrigation.
One of the most frequent mistakes that can affect the development and health of your geraniums is improper watering, whether it be too much or too little. A bacterial or fungal infection can restrict the growth of your geraniums and frequently causes drooping or browning of the leaves, stems, or flowers.
It can be difficult to tell whether you are feeding your geraniums the appropriate amount of water and whether they have an illness of some sort. See how we’ve simplified it so that everyone, from the seasoned green thumb to the novice gardener, can grasp it by continuing to read!
Remember, in this comprehensive guide on how to cultivate geraniums, we have additional information on how to set up your geraniums and how to care for them.
Do geraniums appreciate little pots?
Wish your life had a little more carefree beauty? Plant some geraniums, maybe. Geraniums are beautiful and low-maintenance plants that belong in planters, planting beds, and perennial borders.
Geraniums can be divided into two major groups. Zonal, fancy-leaf, ivy, perfumed, and Martha Washington (or regal) varieties of annual geraniums (Pelargonium species), which often only live for a year, are some examples. Perennial geraniums (Geranium species), which bloom continually from spring to summer, combine striking foliage with attractive blooms that emerge intermittently or continuously.
Where to Plant Geraniums
You must be aware of the type of geraniums you have in order to select the ideal planting location. With the exception of the ivy geranium, which thrives in mild shade, most annual geraniums require a location in full sun. On the other hand, depending on the variety, perennial geraniums can grow in either sunlight or shade. In the country’s southern and western regions, both types profit from shielding from the sun during the warmest time of the day.
What Kind of Soil to Use for Geraniums
Geraniums grow best in healthy, well-draining soil, which is ideal for both perennial and annual geraniums. Improve soil drainage and quality when growing geraniums in planting beds by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 to 8 inches of native soil. When growing geraniums in pots, Miracle-Gro Potting Mix should be used because it is light and fluffy. For the ideal planting medium, combine garden soil and potting soil in equal portions, or fill raised beds with Miracle-Gro Raised Bed Soil.
How to Plant Geraniums
Starting with young plants, such as the premium geraniums from the Miracle-Gro Brilliant Blooms collection*, is ideal (and simplest). Geraniums, both annual and perennial, benefit from warmth, so postpone planting in the spring until all risk of frost has passed. Once the summer heat subsides in the fall, you can also plant perennial geraniums. Try planting perennial geraniums from late fall to early spring in areas with mild winters.
Geraniums range in height from 4 to 48 inches tall and 6 to 36 inches wide, depending on the variety. For information on the recommended spacing for your type of geranium, consult plant tags. Use a pot that is at least 10 inches across for annual geraniums or at least 12 inches across for perennial geraniums when planting geraniums in pots.
Geraniums should be watered thoroughly after planting, giving the root ball and surrounding soil time to absorb the water.
How to Water Geraniums
Check the soil once a week for annual geraniums, and water when the top inch is dry. During their initial growth season, keep newly planted perennial geraniums in continuously moist soil. With the exception of periods of extreme drought, perennial geraniums can typically thrive on rainfall after they are established.
How to Mulch Geraniums
After planting geraniums, cover the area with a 2- to 3-inch layer of mulch to help keep the soil moist and to prevent weed growth and sun exposure. Use Scotts bagged mulch, chopped leaves, pine straw, or another material that is easily obtainable in your area.
How to Feed Geraniums
Your plants receive an excellent starting dosage of nutrients when you start with rich, nutrient-rich soil. However, you should also feed them frequently all season long for maximum results. Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food to your geraniums a month after planting to give them the extra boost of nutrition they require for magnificent blooms. Make sure you adhere to label directions.
How to Grow Perennial Geraniums
Even in the coldest climates, perennial geraniums don’t require particular care to survive the winter. After the initial flower flush, cutting perennial geraniums back by around one-third can encourage more blooms. Cut stems back as necessary if hardy geraniums like “Rozanne” or “Pink Penny” spread out too quickly and widely. These vining geraniums can have up to two-thirds of their length removed, and the plants will still grow back. To encourage new growth and prevent wilted leaves, prune cranesbill geraniums to 2 to 4 inches height after flowering.
How to Use Geraniums
Annual geraniums are excellent at stealing the show in planters and flowerbeds. Regal geraniums can resist cool weather and form lovely hanging basket plants, making them an obvious choice for planting in the early spring. Ivy geraniums are very stunning. Geraniums with aromatic leaves are strong in containers and form a lovely patio display where the leaves may be stroked and enjoyed.
In gardens with some shade, perennial geraniums add much-needed color and can thrive next to mature trees. While mid-size perennial geraniums go well with lanky shrubs, shorter perennial kinds create beautiful ground covers.
