Beautiful flowering plants for beds, borders, containers, hanging baskets, and window boxes include garden geraniums (Pelargonium x hortorum). From May till frost, geraniums add color to the garden and are simple to grow. There are red, pink, salmon, orange, white, lavender, and bi-colored flowers available. Several fancy-leaf geraniums have leaf markings that are silver, white, gold, red, or purple.
When there is no longer a chance of a frost, geraniums should be planted outside. In central Iowa, mid-May is typically a good time to grow geraniums. In full sun and good, well-drained soil, geraniums thrive. Partial shade will allow plants to flourish, but they won’t bloom as well. Geraniums require a minimum of 6 hours a day of direct sunlight for the best blooms. Fertilizer applications work well on geraniums as well. Apply and mix 1 to 2 pounds of an all-purpose garden fertilizer, like 10-10-10, per 100 square feet of garden space before planting. Every two weeks or so, fertilize container-grown geraniums using a diluted fertilizer solution. For plants in beds and borders, a deep soak once per week is sufficient during dry spells. Containerized plants will need to be watered more frequently. When the soil surface feels dry to the touch, water geraniums in containers. Avoid overhead watering as much as you can since moist foliage promotes the growth of disease. In order to keep plants blooming throughout the growing season, regularly remove spent blossoms. Deadheading promotes plants to generate more blooms and stops the formation of seeds. Additionally, it makes plants seem better.
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.

Do geraniums require fertilization?
Geranium fertilization throughout production is crucial for maximizing development, and fertilizer issues must be avoided by having a thorough understanding of full nutrition management.
A water soluble fertilizer is frequently applied by many growers. Although this is a fantastic way of fertilizing, it is crucial to apply enough water to ensure that each time you water, enough water drains or drips down the medium. Insufficient watering will cause a buildup of fertilizer salts in the medium. In many cases, the overall fertilizer content (soluble salts) of the medium will rise to levels that will significantly restrict plant growth.
200 to 250 ppm of nitrogen is typically advised for geraniums when fertilizing them continuously. Experience reveals that a continuous fertilizer program reduces nutritional issues.
Fertilizer kinds include 20-10-20 Peat-lite, 15-15-15 (Geranium Special), and 15-16-17 Peat-lite. EXCEL Limestone could be supplemented with Cal-Mag 15-5-15 to add Ca and Mg.
Fertilizer rates and methods: 150–200 ppm N using subirrigation or another constrained leaching scheme, or 200–250 ppm N constant liquid feed. Start fertilizing when you plant. observe pH and salt levels. Ivy geranium baskets without saucers can drain properly.
How frequently should I give my geraniums Miracle Grow?
All the vital elements that plants require to survive and develop are present in plenty in Miracle-Gro All-Purpose plant food. Every one to two weeks, give the geraniums some food. The nutrients are delivered to the plant instantly thanks to this water-soluble mixture’s quick release.
Geraniums thrive best when they have access to water, sunlight, and healthy nutrition. Mix 1 tablespoon of the fertilizer with 1 gallon of water to fertilize geraniums in the garden. For indoor or containerized geraniums, combine 1/2 teaspoon with 1 gallon of water.
Sizes for this plant food include 5 pounds, 6.25 pounds, and even 24 individual packets. This fertilizer’s analysis is 24-8-16.
Reviewers observed that this multipurpose plant food significantly benefitted their plants, making them more vivacious and colorful. Even one reviewer claimed that her plants now attract attention from passing motorists who want to snap photos of the blossoms.
What fertilizer is ideal for geraniums?
Every spring and fall, add compost to the soil. Geraniums grown in well-composted soil don’t require fertilization, however using Searles Robust controlled-release fertilizer will result in better flowers. Never fertilize geraniums with a high nitrogen content; you’ll get lots of foliage but few flowers. Additionally, too much nitrogen can make the stems brittle and susceptible to rot.
Why are my geraniums’ leaves going yellow?
Having too much moisture or overwatering is one of the most frequent reasons of yellowing leaves. Geraniums typically have yellow leaves at the bottom when they are overwatered. They could also get water patches that appear pale. If so, you should cease watering right away so that the plants can dry off. Remember that geraniums do not like excessive amounts of water and are drought-tolerant plants.
Geranium yellow leaves can also occur when the water or air are too cold. Since geraniums prefer warm climates, they struggle in cool climates. Geraniums with yellow leaves can be caused by prolonged cold weather, particularly cold, wet weather, or by cold snaps in the spring.
Additionally, a nutrient deficit could be the reason why the geranium leaves turn more yellow than green. Every third watering or once a month, geranium plants should be treated with a comprehensive, water-soluble fertilizer (ideally one with micronutrients). Geraniums’ yellow leaves can be avoided using fertilizer, and the plant will grow larger and produce more blooms as a result.
A geranium with yellow leaves sporadically indicates the presence of a disease. Verticillium, for instance, is a fungus that can result in stunted growth, withering, and brilliant yellow leaves.
What about the yellow-edged geranium leaves? Dehydration or a lack of water are frequently blamed for geranium leaves that have yellow margins or yellow tips. Geraniums require some water even though they can withstand drought. In these situations, you can use your fingers to feel the soil to gauge how dry the plants may be and water accordingly. Trimming the yellowing growth off might also be beneficial.
You can see that geraniums with yellow leaves often only require a little tender loving care in order to recover. If you provide a geranium with what it need, the leaves won’t turn yellow.
What happens if geraniums receive too much fertilizer?
When compared to geraniums grown in more organic soil, sandy soil need more regular fertilizer. However, using too much fertilizer can cause less flowering. Depending on your soil type and the general health of your geraniums, adjust your fertilizer regimen. By mulching your plants with 2 inches of pine needles or other organic mulch to keep the soil cold, you may keep geraniums blooming during periods of extreme summer heat.
How frequently should geraniums 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 potted geraniums require fertilizer?
Fertilizer is necessary for geraniums to blossom healthily, especially when they are grown in pots. Potted geraniums can’t collect nutrients from the soil like plants that are grown in the ground, so you’ll need to provide some.
Use a time-release fertilizer to feed your geranium once in the spring, or use an all-purpose granular fertilizer in the spring and summer. If the potting soil has fertilizer included, you won’t need to feed your plant at all for the first several weeks.
Instead, a water-soluble fertilizer like a flower and bloom plant food is beneficial for geraniums. Water-soluble fertilizers are trustworthy and simple to apply when combined in a watering can and administered every two weeks during the growing season.
