Why Are My Perennial Geraniums Not Flowering


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.

What are the raised, brownish bumps on the back of my ivy geranium leaves represent?

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.

How do I make my geraniums bloom?

Like any other annual summer flower, your geranium is planted. You believe you have provided it with everything it requires, but it won’t grow.

With my Geranium plant, I experienced a similar circumstance. After starting it from seed and giving it proper care, I placed it outside once all danger of frost had passed.

As they are commonly known, geranium flowers are utilized in pots and annual borders. Their flowers bloom off long, thin stems, and they have a very distinctive foliar aroma. Three common flower colors are red, pink, and white.

The Geranium flower is named incorrectly, nevertheless. What we commonly refer to as geranium is actually the delicate perennial Pelargonium, which was first found in Southern Africa.

Actually known as Cranesbill, the real Geranium is a tough perennial plant. Pelargonium and geranium are both members of the Geraniaceae family.

My Pelargonium, as I already indicated, did not blossom this summer. After much waiting, I made the decision to pot up my tiny Pelargonium and bring it inside in the hopes that it would one day blossom. If not, save it for as long as you can and maybe plant it next summer.

My small Pelargonium began to grow a stem that protruded from its center after approximately two weeks of being indoors and near to a sunny south-facing window. I found flower blossoms on it a few days later.

These small buds slowly began to emerge throughout the week, revealing stunning pink flowers.

The summer just past was incredibly warm and dry. Compared to prior summers, this one was unusual. But it didn’t assist my tiny pelargonium bloom in any way.

What Pelargonium (Geranium) requires in order to bloom:

  • requires at least 6 hours of daily direct sunlight to become sufficiently energetic to blossom.
  • needs to be facing south or west, where the sun is the strongest and most direct.
  • It needs a window with direct light, facing West or South, if blooming indoors.
  • need a minimum temperature of 15 celsius (60F) at night and 21-30 celsius (70-85F) during the day. The bloom time will shorten if the heat arrives too early in the season.
  • It prefers moist soil, however excessive irrigation will prevent it from blooming. The plant will suffer if the soil around its roots becomes wet since the roots won’t be able to absorb oxygen.
  • Flowers just need a small amount of balanced fertilizer (such as 10-10-10) every two to four weeks to stay in bloom, but they will also bloom without it.
  • The quantity of sunlight a plant receives affects how many flowers it produces.

How do you maintain the flowering of perennial geraniums?

How to Increase Hardy Geranium Blooms

  • Give the Right Lighting. Make sure your blooms are receiving enough sunlight.
  • Maintain Soil Moistness. Keep the soil damp but not soggy.
  • Detach any leggy growth. Midsummer is the time to prune the plants.
  • Give Your Plants Food. To promote blooming, apply a fertilizer strong in potash.

How should a perennial geranium plant be cared for?

There is no “one size fits all” care for geraniums because there are so many different kinds available in the trade. Perennial geraniums are fortunate to be hardy and versatile. Geraniums may thrive anywhere from full sun to partial shade. Many cultivars can also thrive in greater shade, though they can produce fewer flowers. Additionally, perennial geraniums enjoy well-drained soil and may complain if it is too damp.

Geraniums benefit from having their stems cut back once they’ve finished blooming. Those plants that bloom on longer stems can be pruned back to their basal foliage development. This will prevent them from looking too disorganized and encouraging fresh development. On some species, it could also give you a scattering of rebloom.

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.
