Swathes of geraniums planted for a carpet of vibrant colors
Transplanting your young geranium seedlings involves two steps:
- As soon as your geranium seedlings are big enough to handle, which could be as soon as 7–10 days after sowing, prick them out into boxes.
- 5–6 weeks after sowing, transplant your geranium seedlings into 3–4in (7.5cm) pots. Use a light, well-drained potting mix in each case, then lightly water the plants in.
Before being planted outside, how big should geraniums be?
Geranium plants have a variety of requirements that will vary depending on where and how they are grown. Geraniums will withstand moderate light levels but require lots of light to bloom indoors. They also require indoor temperatures of roughly 65–70°F (18–21°C) during the day and 55°F (13°C) at night.
Additionally, these plants need to be planted in potting soil that drains properly. Geraniums need a soil mix with equal parts soil, peat, and perlite when grown outdoors. The soil should be wet and well-draining.
Place your geraniums in a location that receives six to eight hours of direct sunlight per day. Wait to plant these plants until the risk of frost has passed because they need to be shielded from the cold.
Plants should be placed 8 to 12 inches (20–30 cm) apart and at roughly the same depth as the pots they were originally planted in. To help plants retain moisture, mulching is also advised.
When should geraniums be transplanted?
Many gardeners enjoy planting geraniums because they are unique beauty that look great in flower gardens or in containers along decks and patios. Geraniums are frequently moved in the fall, right before the first frost, and brought indoors for the winter to maintain their growth. Your geranium should start to show signs of fresh growth after the first month of transplanting and should cheer up your house till spring.
Find a terra clay container that is only marginally bigger than the one your geranium is now in. An 8-inch pot should work if your geranium is planted in the ground. Layer small rocks or pieces of terra cotta in the bottom of your container before adding potting soil until the pot is only one-third filled.
Either take your geranium out of its current pot or dig it up from the ground. Maintain the plant’s root ball in an intact, solid mass as you operate to minimize stress on the plant. Put the plant in the container.

- Layer small rocks or pieces of terra cotta in the bottom of your container before adding potting soil until the pot is only one-third filled.
If necessary, raise or lower the soil level beneath the root ball until its upper level is an inch or so below the pot’s rim. To fill in any gaps between the root ball and the pot, add extra potting soil around the base of the plant.
Set the plant in a sunny location in your house for the winter, watering it thoroughly to keep the soil evenly moist. At this area, your geranium needs to be exposed to direct sunlight for four to six hours each day.
As often as necessary, add enough water to thoroughly moisten the soil after allowing it to dry. Every four to six weeks, fertilize your geraniums as directed by the manufacturer, taking into account the size of your pot.
Once your area has had its final spring frost, place the geranium back outside. The plant can be either let to grow for the entire year in its current pot or it can be planted in the ground.
- If necessary, raise or lower the soil level beneath the root ball until its upper level is an inch or so below the pot’s rim.
Instead of repotting your current geranium, you can take 6-inch-long cuttings and root them indoors in wet soil. Your new geranium plants will be prepared for putting into larger containers by the spring.
Does it need to be done to geranium seedlings?
A delicate perennial, geraniums are frequently planted outside as annual flowers. There are numerous variations that are offered in a variety of hues. Geraniums thrive and bloom in partial shadow, which makes them a great addition to gardens with little light, in contrast to many other flowering plants. When planted in containers that are carried indoors during the winter, geraniums also flourish all year round. Whether the geranium is placed in a bed or a pot, pinching back the plant promotes full, bushy growth and further blooming.
In the spring, prune back overwintered plants before they resume active growth. Trim all foliage and stems that are dead or damaged, but only by around two-thirds of their previous height. For pruning, use well-kept, razor-sharp scissors.

Once the plant is actively growing once more or after relocating fresh plants to a permanent bed or pot, pinch off the top 1/2 inch of each stem. This promotes further branching and results in a fuller plant.
When the blossoms start to wilt, pinch them off. Pinch off the top of each blossom stem just above the nearby leaf cluster. As a result, no seeds are produced, and more buds are set.
Geraniums should be revived in the middle of the summer if they start to seem lanky or worn out. In order to give the plant a rounded appearance, pinch off the top 3 to 5 inches of each stem. Each stem should have a leaf or leaf node directly above it. The geraniums will immediately become bushier and start blooming once more.
- Once the plant is actively growing once more or after relocating fresh plants to a permanent bed or pot, pinch off the top 1/2 inch of each stem.
Even while pinching with your fingers works well for most trimming, shears can be used if the entire plant needs to be rejuvenated.
After significant cutting, fertilize the plants. This promotes the plant’s rapid growth of foliage.
Following pinching, plants may stop blooming for one to three weeks. If you keep giving them regular water, they will soon start blooming again.
Can I plant geraniums outside yet?
If you don’t have an indoor room, cover the tray with horticultural fleece and leave it in a protected area of the garden. When your geraniums first arrive, place the tray in a frost-free, light, draught-free environment. Water gently by misting or by standing in a shallow tray of water.
Give the plants 24 hours to relax. If the leaves appear a little yellow or if some compost has separated from the root blocks, don’t be concerned.
Large-sized geraniums can be planted right away as long as the risk of frost has gone, while medium-sized geraniums should be nurtured on for 24 weeks before planting.
- Be sure to water your plants well.
- Push the individual cells up from bottom and out of the tray with your finger or a pencil. Grasp one of the leaves and carefully pull yourself up. Avoid attempting to grip the stem since doing so will seriously harm the plant.
- Create a tiny hole in each 9 cm pot of compost and fill it with the cell (one plant per pot). Make sure the joint where the stem and leaves meet is above the surface of the earth, then gently press the plant into the ground.
- After transplanting, give the plant a gentle watering and place it somewhere warm and out of direct sunshine.
- After a week, feed with a liquid feed and maintain well-hydrated.
- They should be prepared for planting after 24 weeks if you maintain the complete stem exposed and the plug submerged so the top of the plug is level with the soil surface. You can plant them in beds, borders, hanging baskets, or planters. After planting, liberally water the area.
- After planting, if there is even a little chance of frost, cover with fleece for the night to prevent the leaves from turning brown.
Do geraniums grow better in the ground or in pots?
Geraniums can be planted in any type of garden soil, but they thrive in neutral or alkaline soil. Grow in flower beds, hanging baskets, or containers that receive direct sunlight.
How to plant geraniums
Choose a peat-free multi-purpose compost with extra slow-release fertilizer when growing geraniums in containers. When paired with other summer bedding plants, geraniums look amazing. They may endure being packed closely together with other sensitive plants if planted in a rich compost and kept well-watered.

Iowa’s AMES
Beautiful plants like geraniums offer color and life to any landscape. They are not prepared to endure the hard winter weather, though. Geraniums can be brought indoors to overwinter and then replanted in the spring.
Horticulturists at ISU Extension and Outreach can assist with your inquiries regarding overwintering geraniums and how to keep them healthy during winter weather.
How can I overwinter geraniums indoors?
By obtaining cuttings, potting up individual plants, or preserving bare-root plants in a cool, dry place, geraniums can be overwintered indoors. Before the first fall frost, remove plants from the garden (or take cuttings).
How do you take geranium cuttings?
Take three- to four-inch stem cuttings from the terminal ends of the shoots using a sharp knife. Pinch the bottom leaves off each cutting before dipping the base in a rooting hormone. Insert the cuttings into vermiculite or a mix of perlite and sphagnum peat moss as a rooting media. Rooting containers that have drainage holes on the bottom are pots and flats. Just enough to allow the cuttings to support themselves should be inserted into the media. Water the rooting media once all of the cuttings have been placed.
Place a clear plastic bag or dome over the cuttings to stop the plant foliage from wilting after allowing the medium to drain for a few minutes. The cuttings should then be placed under bright light—not direct sunshine. In six to eight weeks, the cuttings should begin to root. Remove the cuttings from the rooting media after they have healthy root systems and plant each rooted cutting in a separate pot. Until spring, keep the potted plants in a window with natural light or under artificial lighting.
How do you overwinter geraniums as potted plants?
Each plant should be dug up carefully and put in a big pot. After giving each plant plenty of water, set the geraniums in a window with natural or artificial light. Geraniums prefer a cool environment indoors. The ideal temperature range is between 60 and 65 degrees Fahrenheit during the day and a little bit lower at night. Plants need watering around every two weeks. By the end of winter, geraniums are likely to grow tall and lanky. Trim the plants back in March. Reduce the geraniums by a third to a half. Within a few days, the geraniums will start to grow once more, and by May, they should be beautiful specimens.
How do you overwinter geraniums as bare-root plants?
The geraniums should be carefully dug out before the first fall frost. Remove the plant’s roots’ soil by shaking them. After that, put one or two plants in a sizable paper bag and keep it dry and cool (45 to 50 degrees Fahrenheit). It might be appropriate to use an indoor porch or an unheated bedroom. Hanging the plants upside-down in a cool, dry area is a another (somewhat messier) option. Eventually, the leaves and the shoot tips will wither away.
Trim or prune each plant in March. Get rid of all the dried-out, lifeless stuff. Return to firm, green, living stem tissue through pruning. After pruning, pot the plants and give them plenty of water. Put the potted geraniums in a window with natural light or next to a light source. March pruning and potting of geraniums should result in lovely plants that may be put outside in May.
Are geraniums sun-loving plants?
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.
