Taking care of Geranium – Pelargonium plant

Geranium - Pelargonium

Geraniums are a longtime favorite of gardeners. With colorful flowers and lovely scents, they grow easily in garden beds, containers, or hanging baskets during the warmer months. Spring is the time to repot them! See how to grow and care for geraniums at home.

The geranium is an iconic, fragrant garden flower. American growers first fell in love with the geranium flower over 200 years ago, and it’s not hard to see why. Geraniums fill hanging baskets, containers and flower beds with fancy leaves that are as attractive as the clusters of dainty blooms they surround. Planting geraniums can be extremely easy and rewarding.

The secret of Geranium

This popular garden plant is hiding a secret – it isn’t a true geranium. Garden geraniums, also known as annual geraniums, are actually from the genus Pelargonium. Originating in South Africa, the garden geranium made its way to North America from France in 1786. Thomas Jefferson’s first geranium cuttings soon multiplied to generations of gardeners as they were passed to friends and family.
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.
In 1753, Swedish botanist Carl Linnaeus classified them under the genus Geranium. When it was later discovered that these new “geraniums” differed from European geraniums in the shape of their petals, the number of stamens, and other factors, they were reclassified under Pelargonium, meaning “stork’s bill” – a reference to the long, sharply pointed shape of their seedpod.

You don’t need to be a master gardener to know how to grow geraniums. Geraniums care little for fancy fertilizers or specialized soils, and they require just a bit of basic care to thrive.

Soil for Geraniums

The perfect soil for geraniums is a loose soil with plenty of organic matter. If your soil is on the heavy side, incorporate peat, compost or perlite. Manure and vermiculite are not recommended.

Where to Plant Geraniums

You can plant geraniums in almost all gardening zones. Despite knowing this, you may still be asking do geraniums need full sun? Geraniums require plenty of sunlight to flower, but in areas with hot summers, a bit of shade is recommended. When it comes to how much sunlight do geraniums need, the answer depends on the specific geranium and your garden zone. The ideal location has morning sun, afternoon shade and well-draining soil. Choose a properly-sized area for your geranium flower beds. Appropriate spacing in between plants will reduce the risk of disease.

When to Plant Geraniums

Don’t rush the planting season – geraniums are not cold hardy. But if you wait too long, you risk missing the cool night temperatures that encourage budding. Knowing how to grow geraniums outdoors begins with planting at the proper time. Wait until the danger of the last frost has passed and your soil reaches 60F (16C).

Fertilizer for Geraniums

Geraniums require light fertilization. If you feed them too much, the foliage will flourish at the expense of the blooms. Although you may see it in your garden center, you don’t need to purchase a specialty geranium fertilizer. For a gentle fertilization, mix 2 tablespoons of a water soluble 20-20-20 fertilizer into 1 gallon of water. Apply this solution every three weeks throughout the growing season.

Growing Geraniums in Pots

Wondering how to plant geraniums in pots? It’s actually as easy as planting them in the ground. You need loose, well-draining soil, consistent watering and low levels of fertilization. Geraniums grow well in containers of all shapes and sizes, as long as they have drainage holes. The key to successfully growing geraniums in pots is to place them in sunny locations and out of damaging winds.
The added benefit of growing geraniums in pots is that you can simply move pots inside during the winter. When placed in a sunny window, geraniums will thrive as a houseplant even in the coldest months. In spring, gradually move them back outdoors after the last frost.

Watering Geraniums

Because you need to water geraniums thoroughly and deeply, take the time to leave an irrigation furrow around each plant to serve as a watering reservoir. This allows the water to pool and then gently filter down through the soil. To avoid root rot, allow soil to become dry between watering. Watering at ground level with a soaker hose keeps water off the foliage and protects against disease. Soil in pots tends to get warm, so growing geraniums in containers requires regular watering. The drainage holes help prevent root rot, so you don’t have to wait for the soil to dry out in between waterings.
How much water do geraniums need? It’s going to require simply watching your plants. For proper geranium plant care, avoid letting your geraniums to wilt. Cycles of wilting and revival will result in poor flower production and the dropping of leaves.

Pruning Geraniums

Annual geraniums that are planted outdoors don’t require pruning, but regular deadheading can help prevent disease and increase production. Simply pinch off the entire flower stalk after the flowers fade and remove dry leaves from the plants. The geranium houseplant tends to become long legged and thin. Regularly prune by pinching the growing points to encourage branching.

Greek name: Γεράνι.
