Geraniums don’t require intensive fertilizing, as was previously said, and liquid fertilizers typically work best because they are less prone to leach from the soil.
If you want to go completely organic, you can also utilize handmade compost-based mixtures.
The Numbers Game: Different NPKs for Different Jobs
Although you can feed your geraniums a balanced liquid fertilizer every two weeks or once a month, it’s a good idea to change things up depending on the season.
These three crucial nutrients have varied functions in the NPK ratio, thus depending on the season, you may require more or less of them.
- The growth of stems and healthy, lush foliage both depend on nitrogen.
- Although phosphorus is necessary for blooms and promotes root growth, too much of it might cause a potassium deficit.
- For a plant to be physically strong and in good health, potassium is necessary.
The first feeding of new plants should be a 5-10-5 since they need to strengthen their root systems.
For the majority of geraniums, both grounded and potted, a balanced fertilizer (10-10-10 as a slow-release fertilizer or 20-20-20 as a liquid water-soluble fertilizer) is ideal.
The presence of yellow leaves on your geranium indicates a nitrogen deficiency. Similarly, phosphorus can cause yellow or red leaves and a failure to flower. Low levels of potassium will result in lower leaves dying and brittle stems.
Additionally, geraniums require a number of macro and micronutrients for growth, which are found in most high-quality plant foods.
The following are the ones for these plants that require the greatest attention:
- Calcium
- Iron
- Magnesium
- Manganese
- Copper
- Boron
- Zinc
More quickly than with other micro- and macronutrients, issues might arise from nutrient deficits in any of them.
The good news is that these flaws are frequently easily remedied.
- Eggshell or bone meal crushed can be used to restore calcium.
- Iron, manganese, and zinc can be found in compost and are also accessible as supplements.
- A teaspoon of Epsom salts can quickly increase magnesium levels.
Additionally, you can add coffee grinds to the soil (along with coffee filters or crushed leaves) to help promote healthy microbes and improve plant growth.
You should also be aware of how much fertilizer your soil already has when it comes to fertilizing your plants.
For outside plants, a soil test is crucial since it can forewarn you of potential issues before they arise.
For instance, if a soil test reveals a high concentration of phosphorus, it is preferable to reduce the amount of phosphorus in your fertilizer somewhat because too much will result in potassium deficits.
This is less crucial for indoor plants because commercial potting mixtures are often pre-balanced and replaced every three years to renew the soil.
The ideal fertilizer for geraniums is…
For mature geraniums, the 20-20-20 rule works well. It will aid in the development of larger blooms and supply the plant with the vital micronutrients it needs to stay healthy. Geraniums receive the proper nourishment from the micronutrients in this package.
Add 2 tablespoons of this fertilizer to 1 gallon of water to dilute it. All the nutrients are provided by this combo.
The PowerPak has received rave reviews from users who claim it has transformed their gardens, fostering the growth of more vibrant, robust plants with larger blooms. Given its pricing and 1 pound of goods, it’s a fairly economical pick.
What do I give my geraniums to eat?
Every two weeks, give your geraniums a balanced fertilizer, such as 10-10-10 or 20-20-20. Purchase water-soluble fertilizer for simpler application. Epsom salts, or magnesium sulfate, should be added to the plant water every third watering to deliver magnesium (1 teaspoon per 1 gallon). Alternately, you can plant the geraniums in the pot and add a slow-release fertilizer to the soil mixture to feed them all season.
Does Miracle Grow appeal to geraniums?
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.

Does geranium fertilizer need to be specific?
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.
How frequently do geraniums need to be fertilized?
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.
The key to raising geraniums is what?
To cultivate geraniums, you don’t have to be an expert gardener. Geraniums don’t require much in the way of particular care and don’t care much for expensive fertilizers or niche soils.
For geraniums, soil
A loose soil with lots of organic materials is ideal for geraniums. Add peat, compost, or perlite if your soil is on the heavier side. Vermiculite and manure are not advised.
Geranium Planting Locations
Nearly all gardening zones are suitable for geranium planting. Even after understanding this, you might still wonder if geraniums require full sun. Geraniums need a lot of light to bloom, although in regions with hot summers, some shade is advised. The answer to the question of how much sunlight geraniums require varies on the particular geranium and your gardening zone. The optimum position has well-draining soil, morning sun, and afternoon shade. Pick a spot that is the right size for your geranium flower beds. The risk of illness is decreased by maintaining the proper distance between plants.
Geranium Planting Season
Planting season shouldn’t be rushed because geraniums aren’t cold resistant. If you hold off too long, though, you run the risk of missing the low nighttime temperatures that promote budding. Planting at the right time is the first step in understanding how to cultivate geraniums outdoors. Wait till your soil reaches 60 degrees F and the threat of the last frost has passed.
Geranium-specific fertilizer
Light fertilizing is required for geraniums. If you overfeed them, the blossoms will suffer while the foliage thrives. You don’t need to buy a specialized geranium fertilizer, despite the fact that you may notice it in your local garden center. Combine 2 teaspoons of a water-soluble 20-20-20 fertilizer with 1 gallon of water for a mild fertilization. Every three weeks during the growing season, apply this solution.
Geraniums in Containers
You may be wondering how to pot-plant geraniums. Actually, it’s as simple as putting them in the ground. You require a soil that is loose and well-draining, regular watering, and minimal fertilizing. As long as the container has drainage holes, geraniums thrive in various sizes and shapes of containers. The secret to growing geraniums in pots is to put them in sunny spots away from windy areas.
Geraniums grown in pots have the extra advantage that you may easily bring them indoors for the winter. Geraniums will flourish as a houseplant even in the coldest months if they are put in a sunny window. After the last frost, gently reintroduce them to the outside in the spring.
giving geraniums water
Take the time to leave an irrigation furrow around each plant to act as a watering reservoir since geraniums require deep, thorough watering. As a result, water can collect and then slowly percolate through the soil. Allow the soil to dry out in between waterings to prevent root rot. Using a soaker hose to water at ground level keeps water off the leaves and guards against illness. Geraniums need to be watered frequently because the soil in pots likes to get heated. You can water plants without waiting for the soil to dry up between applications since the drainage holes assist prevent root rot.
What volume of water do geraniums require? You’ll just need to keep an eye on your plants. Avoid allowing your geraniums to wilt for proper geranium plant care. Poor flower production and leaf shedding occur as a result of withering and revival cycles.
Geranium pruning
Outdoor-planted annual geraniums don’t require pruning, but routine deadheading can help reduce disease and boost growth. After the flowers have faded, simply pinch off the entire flower stalk and pick the plants’ dried leaves. The geranium houseplant frequently develops long, slender legs. Pinching the growth tips on a regular basis will promote branching.
Geranium Common Pests and Diseases
Geraniums are generally free of insects and other pests. Botrytis and other fungus attacks, however, can happen in cooler, rainier climates. Commercial fungicides offer some level of defense. Oedema and root rot are two issues that can result from overwatering.
