How To Grow Geraniums In Containers

Place the pot on the south side of walls, on patio tabletops, or as an accent in sunny areas of the garden to provide geraniums the six to eight hours of full sun they need each day to blossom well. Don’t freak out if you see that your plant isn’t blooming in the summer. If you live in a hot area, simply move your container to a location where it will receive some afternoon shade because geraniums have a propensity to stop flowering during particularly hot weather.

How are potted geraniums cared for?

Gardeners have traditionally favored geraniums. They smell wonderful, are colorful, and are simple to grow. How to cultivate geraniums in your house and garden is provided here!

(Note: This page is about Pelargonium plants, sometimes known as geraniums or storksbills. This is not a page about “hardy geraniums, also referred to as cranesbills.

Geraniums are normally kept indoors to overwinter, even if they may be kept outside throughout the warmer months of the year. In contrast, if given enough light, they can bloom all year long indoors.

Geranium or Pelargonium? A Case of Mistaken Identity

Early in the 18th century, Dutch traders who were traveling through South Africa brought the plants that we now refer to as “geraniums” to Europe. Botanists misclassified these new plants into the same genus because they resembled the hardy wild geraniums that are already present throughout Europe.

Botanist Carl Linnaeus of Sweden included them in the genus Geranium in 1753. Pelargonium, which refers to the long, sharply pointed shape of their seedpod, was used to reclassify these new “geraniums when it was later revealed that they differed from European geraniums in the shape of their petals, the number of stamens, and other features.

However, people still refer to them by their old common name, “geranium,” even if we really mean “pelargonium.”

  • You can grow geraniums as annual blooms or as indoor plants. They can be kept outside in a sunny area throughout the warmer months of the year (between your local frost dates).
  • If keeping geraniums as indoor plants, make sure to do so in the late summer or early fall when overnight lows begin to consistently fall below 55F. (13C).
  • Pay great attention to the size and color of geraniums when purchasing them. Healthy stems and leaves will not be straggly or discolored on top of them or underneath them. A plant with evident insect indications should also be avoided. Mealybugs, whiteflies, and spider mites are typical indoor plant pests.
  • To prevent root rot, put plants in containers with drainage holes.
  • When planting in pots, use a well-draining potting mixture rather than heavy, clayey soil. Geraniums dislike being planted in mucky, compacted soil.
  • Place the plants where they will receive 4-6 hours of sunlight per day for the best bloom.

How to Care for Geraniums

  • After letting the soil somewhat dry between waterings, water it again well.
  • Water plants significantly less throughout the winter, but make sure the roots are not completely dried up. Given a time of hibernation throughout the winter, when they consume less water and don’t grow as much, geraniums thrive. For additional overwintering tips, see the section below.
  • Regularly deadhead spent flowers to promote blooming.
  • Pinch back the stems to encourage bushiness and prevent legginess.
  • Fertilize approximately every two weeks throughout the active growing months. Half-strength a fertilizer that is water soluble When the plant should be dormant in the winter, avoid fertilizing.
  • Repotting geraniums can be done in the spring to promote new growth or if they appear to need revitalization.

Overwintering Geraniums

  • If they receive plenty of sunlight, geraniums that have spent the summer outdoors can be kept indoors. The sun may not be strong enough in northern regions in late winter to promote buds on some cultivars.
  • Lift the plants before the first fall frost (you can find your local frost dates here), and use a sharp, clean knife to shapely prune the stems back to about 6 to 8 inches. In the low-sunlight environment they are about to enter, they shouldn’t have to maintain substantial amounts of leaves. A simple technique to increase the number of your plants is to save a few stems for rooting.
  • Place the “mother plant” in the smallest pot you can find—just big enough to hold the roots—and fill it with ordinary potting soil.
  • The plants should be kept in the shadow for a week before being moved to a sunny location and kept cool.
  • Geraniums thrive in temperatures between 50 and 60 degrees Fahrenheit (10 and 16 degrees Celsius) at night during the winter, but they can also withstand lows of 32 degrees Fahrenheit (0 degrees Celsius) and highs of 80 degrees Fahrenheit (27 degrees Celsius), provided they are kept relatively dry.
  • Cut off all the old leaves when the spring growth begins.

Keeping the new growth alive is the only challenge that can compare to getting it to appear. Here is some assistance with that:

  • Only offer tiny quantities of water when the leaves begin to droop. Don’t feed or fertilize the plants. These plants must have some downtime.
  • Pinch back your overwintered geraniums in February if you want them to bloom by Memorial Day. Take the plants outside and move them to beds or pots, as you like, once warm weather returns and all threat of frost has passed.
  • Containers are ideal for growing the Common or Zonal Geraniums (Pelargonium x hortorum) (as well as outdoors).
  • Hanging baskets, window boxes, and containers are all extremely popular places to use Ivy-Leaf Geraniums (Pelargonium peltatum).

How to Root Stem Cuttings

The majority of geraniums readily take root from stem cuttings when placed in soil, sand, water, perlite, or another rooting medium.

  • Make a slanted incision 4 inches below the tip of the stem, above the node where the leaves emerge, with a clean, sharp knife. Cut the grass immediately below a node. Remove all except two or three leaves, any buds, and the stipules that resemble leaves at the base of leaf stalks.
  • To ensure that the cut end of the stem will seal and not rot, roll the stem cutting in newspaper or place it in the shade for 24 hours.
  • Place the stem in a wet rooting media container and keep it there for two days in a warm, shaded area. Give the cutting indirect sun after that. Just as needed, moisten the medium.
  • Apply crushed geranium leaves to small cuts to halt the bleeding.
  • Scarlet geranium is the flower that speaks of foolishness. More floral meanings can be found here.
  • You won’t have to worry about those bothersome bugs because geraniums are known to be harmful to Japanese beetles.
  • Keep geraniums out of the reach of curious youngsters and animals (cats, dogs) as they might cause indigestion or vomiting.

Low light, overexposure, and underwatering are common issues. Yellowing leaves are a sign that you are watering your plants either too little or too much. Try to water the geraniums evenly in this situation, and transfer them to a more sunny location.

Do geraniums flourish in pots?

Few flowers in a pot look as wonderful as these ones do. Large clusters of magnificent blooms in shades of red, pink, rose, salmon, orange, lavender, violet, or white are mingled with attractive foliage. Although geraniums are frequently used as bedding plants, we believe they thrive in containers.

2 primary plants You can certainly find four or five distinct types of geraniums if you scour enough garden centers. However, two are responsible for practically all of the sales. The common geranium is the first and most widely grown (Pelargonium x hortorum). Because of the burgundy ring that frequently surrounds its rounded, velvety, green leaves, it is also sometimes referred to as a zonal geranium.

Common geraniums are typically treated as annuals, although in parts of the Southern Coastal and Tropical regions where it doesn’t freeze, they are perennials. Age causes succulent stems to turn woody, and plants develop into attractive shrubs. If you want to grow plants this manner outside of these places, you must keep the plants indoors, next to a window, during the winter.

The ivy geranium (P. peltatum), so named for its glossy green, ivy-shaped leaves, is the second most popular variety. This geranium cascades in growth as opposed to growing erect like regular geraniums. Use it to jump from window boxes, hanging baskets, or the edge of a large planter.

How To Grow Geraniums prefer rich, organically-rich soil that is fertile and well-drained. Between waterings, let the soil become just a little bit dry. Avoid overfertilizing: Feed them with liquid 20-20-20 fertilizer three times throughout the growing season or slow-release, granular fertilizer once in the spring. To keep the plants blooming, regularly remove fading blossoms. The ideal exposure is early full sun with afternoon mild shade.

Ideally Known These plants may suffer damage from the intense summer heat. In hot temperatures, many common geraniums stop blooming, a phenomenon known as “heat check.” (When cooler weather hits, they’ll start flowering again.) Grow heat-tolerant varieties like the Americana, Eclipse, Fidelity, Maverick, and Orbit Series to prevent this. Even less tolerant to excessive heat are ivy geraniums, which thrive in the Upper and Middle South. However, across a large portion of the Lower South, the heat-tolerant Blizzard, Cascade, and Summer Showers Series perform well. Likewise, “Sofie Cascade.” Ivy geraniums can be grown as winter annuals in the coastal and tropical South.

What is the lifespan of geraniums in pots?

My geraniums are no longer blooming. I fed them, but it was ineffective. What’s the issue?

You might be feeding them too much. Pelargoniums, a genus of geraniums native to the Mediterranean, flourish in full sunlight and relatively infertile soil. Overfeeding can be the issue if you have a lot of foliage growth and the plants appear healthy. For a while, stop giving them food. But if your plants are becoming older and their stems are getting lanky, it might be time to propagate. Although they can live much longer, geraniums typically only bloom for two years on average before becoming woody and losing their blooming ability. Thankfully, geranium propagation is simple. Simply cut stem tips with at least two pairs of healthy leaves from a four-inch stem. Cut the stem at the lowest point, dunk it in hormone rooting powder, and then plant it in a mixture of half sand and half peat moss. In around three weeks, repot in ordinary soil after providing adequate watering and covering with plastic to assist preserve moisture. Sticking the cutting in water and letting it grow roots before potting is a simpler method.

How do you keep geraniums in pots from blooming?

Deadhead faded flowers on your geraniums by cutting off the entire flower stalk all the way to the point where it connects to the main stem.

Use a pair of sharp scissors, or even your fingers, to trim or pinch off approximately a half-inch of growth from the end of each stem to keep plants bushy, full, and jam-packed with flowers. This gives the plant a larger appearance and the potential for more flowers while also causing the plant to sprout two new stems.

Repotting your geraniums into a larger container only when necessary, and use a container that is just one size bigger than the previous one, as geraniums bloom best when they are relatively root-bound.

Geraniums are heavy feeders, so treat your plants with a balanced fertilizer as directed on the product label every few weeks during the spring and summer. At the conclusion of the summer, stop feeding.

Do I need to remove the dead geranium flowers?

Without deadheading, the blooms will soon stop blooming and have a propensity to grow sparse. Additionally, this method stops the plant from producing new seeds. When your geranium blooms start to look weak or brown, you should deadhead them.

If you want to deadhead your geraniums, you need to go a bit further into the plant and snap the stem below the node or junction, where new growth starts. You have the option of using shears or only your hands. Healthy, well-watered plants have stems that are simpler to snap.

Deadheading will foster the growth of fresh, full blooms in place of any that appear weak or less full. Work your way through your plant, doing this in all of its parts. Within a few days, new, fresh blossoms will start to appear. The entire procedure just takes a few minutes, but it can extend the life of your plants by many weeks or even months. You can either pick a few stems each day while taking care of your plants, or you can do this every couple of weeks if you have the time.

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.

How frequently do geraniums in pots need to be watered?

Generally speaking, water geraniums 12 times a week. However, geranium watering requirements can vary based on the environment, the weather, and other significant considerations. A zonal geranium will require more watering in the late summer than a perennial geranium will in the winter. Place your finger in the soil to determine when geraniums need watering. This method is the simplest and least expensive. It’s time to water if the top 2 inches (5 cm) of soil are dry.

  • When the top 2 inches (5 cm) of soil feel dry to the touch, water geraniums.
  • If you don’t want to get your hands dirty, you can measure the amount of moisture with a moisture meter.

Utilizing a soil moisture meter is another way to monitor soil moisture levels. To determine when your container geraniums require additional water, use this moisture meter. Before watering, wait until the needle is in the top end of the “dry region. Until the needle reaches the top of the “wet region,” add water. Keep it out of the “wet region.”

Do geraniums like shade or the sun?

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.
