Although geraniums are typically thought of as an annual plant by gardeners, they are actually perennials. That is, if you are in zone 10 or zone 11, which have warmer, tropical temperatures and never experience a strong frost or ice.
However, because they have perennial roots, there are a few crucial factors to consider in order to make them bloom more lavishly when grown as an annual. And it all starts by pruning back these quickly expanding plants to encourage a more compact, strong growth pattern.
One that can produce a greater number of subsequent blooms throughout the growing season in addition to producing a bigger, more dense group of initial blooms.
#1Pinching Back Geraniums, How To Keep Geraniums Blooming
If geraniums are allowed to grow on their own, they can become rather lanky and sparse. especially when they are developing in hanging baskets, containers, or pots.
The plants usually grow as quickly as they can outward because the soil space is limited. In order to promote thicker and more dense growth, it is crucial to pinch back stem growth.
It is preferable to begin early in the growing season by pinching back every inch of stem development. With a pair of scissors, a pair of garden pruners, or even with sharp fingernails, this is simple to accomplish.
The plant will produce more shoots from the stems it has been pinched back. Mid-summer, even more developed plants can benefit from a small amount of pinching back. It makes the plant considerably bushier and healthier. And a plant that has the capacity to sprout many additional blossoms and flowers.
#2Deadheading Spent Blooms, How To Keep Geraniums Blooming!
When the first geranium blooms appear and begin to bloom, it is time to start deadheading. For many annuals and perennials, regular deadheading—the removal of spent blooms—is essential to ensuring continuous blooming. (View: Deadheading Flowers)
In fact, it’s frequently the single biggest factor preventing geraniums from blooming vigorously throughout the season. The plant continues to expend vital resources and energy on the failing flowers if the old blooms and stems aren’t removed.
For fresh blossoms, shoots, and flowers to grow, energy must be available. It’s time to remove the bloom and stem as soon as they start to fade and die off. Take caution when cutting the flower stem and flower head back to the plant’s root system.
As a result, the plant no longer expends any energy on the old bloom and stem and instead concentrates energy on developing fresh flowers.
Always remove any fading or damaged foliage from the plant in addition to deadheading. Plants use a lot of energy trying to repair damaged foliage, just like with old blossoms.
#3Fertilizing & WateringHow To Keep Geraniums Blooming
Geraniums can gain a lot from a regular dosage of all-purpose fertilizer even if they are not particularly good soil feeders. especially for plants growing in pots and hanging baskets, where soil volume and nutrient availability are constrained.
It is preferable to fertilize gradually rather than in massive, one-time doses. The plant can use the extra energy for blooming rather than rapid growth of big leaves because it maintains an even rate of growth.
Use a light dosage of an all-purpose liquid fertilizer every 21 to 28 days for the greatest results. Liquid fertilizers quickly deliver nutrients by absorption via the plant’s roots and leaves. Mix at roughly half of the usual recommended rate to keep the dose on the lighter side.
Water SmartHow To Keep Geraniums Blooming Strong
Finally, watering is essential for the development and maintenance of blooms. A stressed plant will halt or possibly cease producing new blooms as a result of inadequate or excessive watering. (See The 4 Easy Tricks To Watering Annuals.)
Geraniums grown in flowerbeds won’t require as much watering as baskets and pots. They simply dry up more quickly, which is the cause of this. In either situation, it’s crucial to avoid letting the geraniums’ roots soak in water for an extended amount of time.
In actuality, giving geraniums larger, more frequent doses of water is preferable to giving them tiny, frequent doses. This makes roots grow deeper and strengthens the plant.
Use the tip of your index finger to inspect the soil before watering. If you sense dampness with your fingertip inserted a few inches into the soil, wait until it has dried completely before watering.
You now know the three easy steps to keep your geraniums blooming profusely this summer.
Pruning Geraniums After Winter Dormancy
The optimum time to prune geraniums is in the early spring if you put them into dormancy for the winter or if you live in a region where they lose some of their leaves over the winter.
Take off all of the geranium’s brown and dead leaves. After that, remove any diseased stems. Squeezing a healthy geranium stem will feel firm. Cut down the geranium plant by one-third, paying particular attention to stems that have begun to turn woody if you want a less woody and lanky plant.
Cutting Back Geraniums That are Wintered Alive
The best time to prune geraniums is in late fall or right before you bring them inside, if you intend to bring them indoors. If you do not put your geraniums into dormancy for the winter and they remain green in the ground or in containers year round.
Trim the geranium plant back by one-third to one-half, paying special attention to lanky or woody stems.
How to Pinch Geraniums
In order to make the plant grow more bushy and compact, geraniums are sometimes pruned. You can pinch either newly purchased bedding geranium plants or geraniums that have been overwintered. Pinching of geraniums begins in the spring.
When a stem on a geranium plant reaches a few inches (7.5–10 cm), cut off 1/4–1/2 inch (0.5–1.5 cm) of the stem with a sharp pair of scissors, or even with your fingers. Repeat over all stems. The geranium will be forced to produce two new stems off of the original stem as a result, which will result in a bushier, fuller plant. If you prefer, you can keep pinching geraniums all throughout spring.
Geranium pruning is simple and improves the appearance of your plant. You may enjoy your geraniums more now that you know how to prune geranium plants.
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 content provides an even supply of nutrients to every part of the plant that helps in photosynthesis. 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.
How can I maintain healthy geraniums?
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
The plants that we commonly call “geraniums were introduced to Europe by Dutch traders who brought them from South Africa in the early 18th century. Because these new plants resembled the hardy wild geraniums already growing in Europe, botanists mistakenly grouped them together into the same genus.
Botanist Carl Linnaeus of Sweden categorized 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 original common name, “geranium,” even though 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.
