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.
What stops geraniums from blooming?
A. Too little light or too much fertilizer are the two most typical causes of geraniums not blooming profusely. Geraniums are a sun-loving flower that require four to six hours of direct sunlight each day, or possibly longer in slightly filtered light. Typically, south and west exposures are ideal. The plant will frequently flourish in an environment with insufficient sunlight, but it will almost always grow taller or leggier as it strives for the light, and it won’t blossom as much. The amount of sun the plant receives has a significant impact on how many flowers it produces. In terms of fertilization, geraniums, like the majority of annuals, will grow enormous, lush green plants instead of a lot of blooms because the plant will be in a more vegetative state. Geraniums do well in containers if you feed them every three to five weeks. Use any of the water soluble fertilizers that are available, but make sure the mixture is balanced (10-10-10 or 20-20-20). Your geraniums will need to be fed less often in the ground; every 4 to 6 weeks should be adequate. It is much preferable to underfeed than overfeed if you are going to fertilize incorrectly.
A. The short answer is no, but some plants will do a little better in a less sunny location. Most Fancy Leaf cultivars with lighter-colored or white-colored leaf can handle a little less light, but they won’t grow in deep shade, and even if they do, they won’t bloom very much.
A. The size of your pots will play a role in this, but it would be greatest if you could alter the soil. Change at least half of larger planters, where that is more difficult, to “freshen” it up. Be sure to choose a soil that contains genuine soil when making your selection. Although a good base, many commercially available mixes that are soil-less require the addition of top soil or black dirt to create a little “heavier” mix that will hold a little bit more water. Due to how quickly smaller pots and containers may dry up in the heat, this is particularly crucial. Because they are so light in weight, the soil-free mixtures are frequently simple to spot in the stores. For the greatest results in your pots and planers, combine some potting soil with one of the soil-less mixtures. Any good potting soil will suffice.
A. Although you are not required to, doing so is unquestionably preferable. Here at the greenhouse, we refer to it as “dead heading,” and you should do it when the blooms are finished and will start to decay at the top, where they also start blooming. Simply take a gentle snap at the point where the blossom stalk joins the plant. This will only encourage the other buds to open up a little earlier because it will come off pretty readily.
A. To begin answering this question, we always mention that all of the geraniums we cultivate are cutting, or vegetative, geraniums. The method by which they are created or spread differs. Cutting geraniums are generated by a cutting, while seed geraniums are formed from a seed. Although it may seem relatively obvious, the differences in performance are likely what matter the most to the gardener. Cutting geraniums often have larger plants and blossoms, but seed geraniums are more slender and have single, more delicate blooms. Both have their functions, so gardeners should merely be aware of them when shopping. In bigger, mass plantings when a lower, extremely even height may be required, seed geraniums are frequently utilized. They are also occasionally used in smaller containers if they won’t significantly outgrow the pot over the course of a season. Cutting geraniums are bigger-growing plants with bigger flower heads that may fill out larger containers and compete with some of the more tenacious plants you might pair them with, like the helichrysum ‘Licorice Plant.
A. There are a number alternative responses to this topic, which is frequently posed. The first rule of gardening still holds true for many of our customers, who have been employing techniques for years that have been passed down through families. If it works, keep doing it. We’ve heard folks doing everything from shaking the soil off the plants to putting them in ice chests in the basement or upside down in brown paper bags in the attic. It was also suggested to look in the garage’s dry cleaning bags and an old dishpan under the ping pong table. As I previously stated, if these work, that is fantastic; nevertheless, geraniums are an annual plant. Geraniums don’t have a dormant season as a result, so people don’t put them to sleep for the winter instead of pulling them back from the brink in the spring. All of these examples show how resilient geraniums really are, but as they are annual plants rather than perennials, they do not die back and sprout new growth every year. Instead, they continue to expand from the same plant structure. So, after being saved for a few years, gardeners will notice that plants start to lose strength and start having smaller leaves and smaller, less frequent blooms. If you want to keep them, your best option is to take a few cuttings in the fall and grow new, fresh plants that you can move indoors for the winter and plant outdoors again in the spring. In essence, that is what we do in our greenhouse, beginning with new plants from cuttings every year in the late summer for the next year. But if it doesn’t work, consider bringing plants indoors and maintaining their growth. Simply cut the plant back by approximately 1/3 to 1/2 and bring it inside. You’ll need a light area, ideally a south or west window. You should water your geranium carefully, just like you would in the summer, and since there is less of a plant and there are less daylight hours, you may only need to do it once per week or once every ten days. Even so, as the plant searches for the light, you might notice some spindly growth; nonetheless, do not be alarmed. To have a bushier plant when it’s time to go back outside, just let the plant grow until the first or second week of March and then chop it down again. In addition, get them outside as soon as you can, even if you have to watch after them at night. Try one or more of these techniques; what have you got to lose? At the very least, it will be a worthwhile gardening experiment.
A. This physiological state is known as oedema (uh-DEEM-a), and it is brought on by cells that burst in the leaves as a result of the plant absorbing excessive amounts of moisture without transpiring. Ivy geraniums typically have a waxy feel, unlike conventional garden geraniums, which have a leaf that is thinner and more permeable. It results from a mix of air humidity, soil moisture, and simply more liquid than the cells can hold. The common misconception among gardeners that it is an insect-caused problem is unfounded. Because it only affects the underside of the leaves, it may only occur once or twice and go undetected. However, in severe situations, when it occurs repeatedly, the spots may pierce the leaf’s surface and eventually cause it to fall off. It most frequently occurs in overcast, rainy conditions. Growing your baskets without saucers will prevent them from sitting in water, and watering early in the day will give the plant time to dry out during the day. Purchasing additional kinds that are less vulnerable to oedema is another option. The Guillou variety, which were developed by the Guillou brothers and are identified as such on the tags, are among the best of them.
#1) Give Geraniums Plenty Of Space & Soil
There are two key aspects of the soil geraniums grow in that must be taken into account in order to maintain their productivity. both soil bulk and soil quality.
In other words, the soil must be fertile enough to supply the nutrients required for vigorous development. Additionally, there must be adequate soil to support a large root system.
Let’s start by talking about the soil’s nutrients. Rich, fertile, and well-draining soil is best for geraniums. It makes it possible for their roots to easily spread out and fast absorb nutrients. Not just those found in the soil, but also those added during the season by supplemental fertilizer.
Unfortunately, roots won’t be able to absorb additional nutrients in the form of liquid or dry fertilizers if the potting soil is poor. Either it passes directly through the plant or it is unable to reach the roots. Both of which will prevent your geraniums from blooming and creating new blooms.
The amount of soil that is accessible for each plant to grow in is also crucial, in addition to the soil’s overall health. This is crucial when growing in pots, containers, and baskets.
Avoiding Small / Shallow Containers
Do not use shallow or small-circumference containers. Smaller containers can soon overheat in the strong summer sun, and plants run out of nutrients and soil space. They quickly dry up as a result, which eventually damages the roots.
Actually, there is a straightforward formula for success: The more area and space there is for soil, the better your plants will do. For best performance, planter boxes should have a minimum depth of 8.
Choose containers for pots or hanging baskets that are at least 12 to 14 inches in diameter. Any less, and the plants are simply too likely to get root-bound by the middle of the summer. Always add a lot of compost to the soil before planting in bed spaces to maintain it fertile and light.
#2) Pruning /Pinching Back Foliage Early In The SeasonHow To Keep Geraniums Flowering
Geraniums prefer to grow more upward than outward if allowed to their natural developing habits. This can make plants and the blooms that result from them appear thin and sparse. However, you can produce a stockier, more robust plant by pinching back the foliage growth in the early part of the season.
For optimal results, pinch down foliage and any stems to roughly 1/3 the size of the plant (we use scissors to clip back). The plant is compelled to grow additional shoots below as a result. As a result, the plant grows stronger, thicker roots at its base. All of this prepares the ground for further buds and blooms to appear during the summer.
#3) DeadheadingHow To Keep Geraniums Flowering
Deadheading is a necessary if you want new flowers to continue to appear all summer long! The act of deadheading involves removing a plant’s wasted blossoms. And your plant will respond by producing even more flowers the more frequently you complete this simple task.
By doing this, you direct the plant’s resources and energy toward making new blooms rather than attempting to save what is already attached to an old stem. A plant will keep trying to send nutrients its way as long as it has dying stems and flower heads on it.
Cut a flower stem back to the foliage as soon as it starts to wane. It won’t just keep your plant looking tidy and orderly; it will also pave the way for future blooms of even greater color!
#4) FertilizingHow To Keep Geraniums Flowering
Although geraniums do not consume large amounts of soil nutrients, a moderate and constant supply will aid to sustain robust growth patterns and abundant blooms. For plants in containers and hanging baskets, this is especially true. See: Hanging Basket Fertilization Instructions
For optimal flowers, feed plants every two weeks with compost tea or an all-purpose organic fertilizer. Compost mulching will also aid in the slow absorption of nutrients into the roots of plants (including those in containers and baskets).
Speaking of compost, always add a few cups to the planting hole for each geranium when planting in bed spaces. The best slow-release fertilizer is compost. For young transplants, working it into the bed gaps will ensure a slow and consistent nutrient basis.
#5) Proper WateringHow To Keep Geraniums Flowering
This brings us to our final and fifth tip, proper irrigation. Overwatering often causes geraniums more harm than not enough water. especially when growing in hanging baskets, containers, and pots.
When planting in a container, it’s crucial to make sure the container has proper drainage. Look for drain holes on the underside of containers. If there is only one, you might want to think about drilling a couple more to help the extra water drain.

Water deeply but less frequently during irrigation. As a result, the roots may penetrate the soil more deeply, improving their nutritional uptake as well as their capacity to preserve water. The plant’s roots are frequently water-logged if the foliage starts to turn yellow. If this happens, stop watering for a few days and make sure the container can release water.
So let’s maintain your geraniums blooming vigorously throughout the summer and take pleasure in their enduring beauty right up until the first frost! Jim and Mary, enjoy your gardening.
