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.
Can geraniums survive the cold indoors?
If given the right conditions, geraniums may survive the winter indoors. They require cool conditions, ideally in the low 60s (F). The majority of basements provide excellent winter home for geraniums. To give your plants ample light, simply add a fluorescent light fixture or a plant light.
How frequently should indoor geraniums be watered?
Geraniums don’t need daily watering unless the soil where they are planted is evaporating that quickly. When the soil is left to dry out between waterings, geraniums flourish at their best. Overwatering can happen if the soil is kept damp at all times. If you don’t allow the soil dry completely, it can be challenging to determine when it’s time to add extra water.
- Typically, geraniums don’t need daily watering.
- Between waterings, let your geraniums’ soil dry out.
- Delay watering your geraniums if the soil is still wet from a recent downpour or precious watering.
- The soil may dry out in a day of intense heat. In this situation, daily geranium watering is OK.
Take proper care to ensure that geraniums in pots or larger containers are drying out between waterings. If the soil is still wet from the last watering, avoid watering. Several geranium diseases can be brought on by not allowing the soil to dry out between waterings.
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.
Geraniums can they bloom indoors?
Pelargoniums, or geraniums, are not only low-cost, colorful bloomers, but also long-lived. They are unable to withstand freezing temperatures, but with some basic care indoors, you can keep them blooming and reblooming all year long.
Pelargoniums can continuously sprout shoots and bloom for months on end, unlike Schlumbergera (Christmas and Thanksgiving Cacti) and African violets, which have distinct bloom and rest seasons.
Can geraniums be kept in pots during the winter?
Geraniums are frequently planted in containers, which is a fantastic option if you want to overwinter them.
In the fall, before the first frost, if your geraniums are already in pots, you can simply relocate the pots under cover into a sunny, airy, and frost-free location, such a greenhouse or conservatory.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “the best area would be a greenhouse and the ideal climate would be to have a heater in place to preserve temperatures above freezing when frost does threaten.” (new tab opens) (PAGS).
You can dig up, repot, and move the pots under cover if your geraniums were grown in a border.
Geraniums should always be pruned back before being brought indoors, whether they are already potted or have been removed from the border and repotted, according to David Taylor of PAGS.
“First, you should prune your plants back by roughly two-thirds; if lifting from outside beds, they could need to be pruned down by three-quarters or perhaps more. Do this pruning only while the roots are dry; otherwise, the remaining stems will wither.”
‘Also, get rid of any diseased, damaged, or dead sections you see. Make sure they are bug-free before bringing them inside for the winter,’ adds Emily Fernandes, a Californian small-space gardener and HouseGrail expert (opens in new tab).
Geraniums are best kept in a semi-dormant state while enclosed, as this means they won’t need as much water or food. “Place them in a partially sunny area, water them every two to three weeks, and maintain a humidity level of about 50%.” According to Emily Fernandes, a consultant at HouseGrail, “they go dormant over the winter like most other plants to store their energy for the growing season” (opens in new tab).
Are geraniums suited for coffee grounds?
Because leftover coffee grinds contain a lot of nitrogen, they can be a beneficial addition to geranium soil. Additionally, they can enhance soil quality and aid in moisture retention. Coffee grounds should be composted first since caffeine can prevent some plants from growing and prevent geranium seeds from sprouting. Utilizing coffee grounds exclusively won’t have the same advantageous results as using a complete fertilizer because they also don’t provide the complete nutrients fertilizers deliver.
Do geraniums respond well to Miracle Grow?
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.

Do I need to remove the yellow geranium leaves?
Having too much moisture or overwatering is one of the most frequent reasons of yellowing leaves. Geraniums typically have yellow leaves at the bottom when they are overwatered. They could also get water patches that appear pale. If so, you should cease watering right away so that the plants can dry off. Remember that geraniums do not like excessive amounts of water and are drought-tolerant plants.
Geranium yellow leaves can also occur when the water or air are too cold. Since geraniums prefer warm climates, they struggle in cool climates. Geraniums with yellow leaves can be caused by prolonged cold weather, particularly cold, wet weather, or by cold snaps in the spring.
Additionally, a nutrient deficit could be the reason why the geranium leaves turn more yellow than green. Every third watering or once a month, geranium plants should be treated with a comprehensive, water-soluble fertilizer (ideally one with micronutrients). Geraniums’ yellow leaves can be avoided using fertilizer, and the plant will grow larger and produce more blooms as a result.
A geranium with yellow leaves sporadically indicates the presence of a disease. Verticillium, for instance, is a fungus that can result in stunted growth, withering, and brilliant yellow leaves.
What about the yellow-edged geranium leaves? Dehydration or a lack of water are frequently blamed for geranium leaves that have yellow margins or yellow tips. Geraniums require some water even though they can withstand drought. In these situations, you can use your fingers to feel the soil to gauge how dry the plants may be and water accordingly. Trimming the yellowing growth off might also be beneficial.
You can see that geraniums with yellow leaves often only require a little tender loving care in order to recover. If you provide a geranium with what it need, the leaves won’t turn yellow.
