Choosing and Preparing the Right Location

Before you start growing regal geraniums, it’s important to choose the right location for them. These plants require specific light, soil, water, and temperature conditions to thrive. Here are some tips to help you prepare the right location for your regal geraniums.

Light Requirements

Regal geraniums require bright, indirect light to grow well. They can tolerate some direct sunlight, but too much can scorch their leaves and flowers. If you plan to grow regal geraniums indoors, choose a spot near a bright window that receives morning or afternoon sun. 

If you plan to grow them outdoors, choose a spot that receives filtered sunlight or partial shade.

Soil Requirements

Regal geraniums prefer well-draining soil that is rich in organic matter. They do not tolerate heavy, waterlogged soil, which can cause root rot. If you plan to grow them in pots, choose a high-quality potting mix that is specifically formulated for flowering plants. 

If you plan to grow them in the ground, amend the soil with compost or well-rotted manure to improve its fertility and drainage.

Water Requirements

Regal geraniums require regular watering to keep their soil evenly moist. However, they do not tolerate standing water, so be sure to provide adequate drainage. If you plan to grow them in pots, choose a container with drainage holes and water them whenever the top inch of soil feels dry to the touch. 

If you plan to grow them in the ground, water them deeply once or twice a week, depending on the weather conditions.

Temperature Requirements

Regal geraniums prefer cool temperatures, ranging from 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius) during the day and 50 to 60 degrees Fahrenheit (10 to 15 degrees Celisus) at night. They do not tolerate extreme heat or cold, which can cause their leaves to wilt or turn yellow.

If you plan to grow them indoors, keep them away from heating vents or drafty windows. If you plan to grow them outdoors, protect them from frost or freezing temperatures by covering them with a cloth or moving them indoors.

Propagating Regal Geraniums

Regal geraniums can be propagated in several ways, including growing from seeds, growing from cuttings, or dividing existing plants. Here are some tips to help you propagate regal geraniums successfully.

Growing from Seeds

Regal geraniums can be grown from seeds, but it can be a slow and challenging process. The seeds are tiny and can take up to ten days to germinate. To grow regal geraniums from seeds, start by filling a seed tray with a high-quality seed-starting mix. Sprinkle the seeds on top of the soil and lightly press them into the surface. 

Water the soil gently and cover the tray with a plastic wrap to keep the moisture inside. Place the tray in a warm, bright location, and keep the soil moist but not waterlogged. Once the seedlings emerge, remove the plastic wrap and place the tray in a sunny location. When the seedlings are big enough to handle, transplant them into individual pots or into the ground.

Growing from Cuttings

Regal geraniums can also be propagated from cuttings, which is a faster and easier method than growing from seeds. To propagate regal geraniums from cuttings, start by selecting a healthy, mature plant with strong stems. Using a sharp, clean pair of scissors or pruning shears, cut a 4 to 6-inch stem from the plant, making sure to include a few leaves and buds. 

Remove the lower leaves from the stem, leaving only a few leaves at the top. Dip the cut end of the stem into rooting hormone powder to encourage root growth, and plant it in a pot filled with moist potting soil. 

Place the pot in a warm, bright location, and keep the soil moist but not waterlogged. After a few weeks, the cutting should start to develop roots and new growth. Once the cutting has established roots, transplant it into a larger pot or into the ground.

Dividing Existing Plants

If you already have an established regal geranium plant, you can propagate it by dividing the plant. To divide a regal geranium plant, start by gently digging up the entire plant from the ground or pot. Using a sharp, clean pair of scissors or a knife, cut the root ball into several sections, making sure that each section has a few stems and roots. 

Replant each section in a pot or in the ground, and water them thoroughly. Dividing an existing plant can help rejuvenate the plant and promote new growth.

Planting Regal Geraniums

Once you have prepared the right location and propagated your regal geraniums, it’s time to plant them. Here are some tips to help you plant regal geraniums successfully.

Planting in Pots

Regal geraniums can be grown in pots both indoors and outdoors. When planting regal geraniums in pots, choose a container that is at least 8 inches in diameter and has drainage holes. Fill the pot with a high-quality potting mix, leaving enough space for the plant to grow. 

Place the plant in the pot, making sure that the top of the root ball is level with the soil surface. Water the plant thoroughly, and place the pot in a warm, bright location.

Planting in the Ground

Regal geraniums can also be grown in the ground, but they require well-draining soil and adequate space to grow. When planting regal geraniums in the ground, choose a spot that receives filtered sunlight or partial shade. Dig a hole that is twice as wide and deep as the root ball, and amend the soil with compost or well-rotted manure. 

Place the plant in the hole, making sure that the top of the root ball is level with the soil surface. Fill the hole with soil, and water the plant thoroughly.

Caring for Regal Geraniums

To keep your regal geraniums healthy and thriving, it’s important to provide them with proper care throughout the growing season. Here are some tips to help you care for regal geraniums successfully.

Fertilizing

Regal geraniums benefit from regular fertilization during the growing season. Use a balanced fertilizer that is formulated for flowering plants, and apply it according to the package instructions. Avoid over-fertilizing, as it can lead to leaf burn and root damage.

Pruning

Regal geraniums benefit from regular pruning to promote bushy growth and prevent legginess. Pinch off the tips of the stems regularly to encourage branching, and remove any dead or damaged leaves or stems. You can also prune back the plant after it has finished flowering to promote new growth.

Pest and Disease Control

Regal geraniums are generally resistant to pests and diseases, but they can be susceptible to fungal diseases if they are overwatered or exposed to humid conditions. To prevent fungal diseases, make sure that the plants have good air circulation and avoid overhead watering. If you notice any signs of pests, such as whiteflies or spider mites, you can treat the plants with insecticidal soap or neem oil.

Winter Care

In colder climates, regal geraniums are not hardy and will not survive the winter outdoors. To overwinter your plants, you can bring them indoors and keep them in a bright, cool location. Water the plants sparingly during the winter months, and reduce fertilization. In the spring, you can start to increase watering and fertilization to promote new growth.

Conclusion

Growing regal geraniums can be a wonderful and rewarding experience for any plant enthusiast. By providing them with the ideal growing conditions, proper care, and attention, you can enjoy the vibrant blooms and sweet fragrance of these stunning plants throughout the growing season. 

Remember to select a suitable location, propagate the plants using the right method, and follow a regular watering and fertilization schedule. Prune the plants when necessary, and keep an eye out for pests and diseases. And during the colder months, don’t forget to overwinter the plants properly to ensure they thrive year after year.

With the information and tips provided in this article, you can grow healthy and thriving regal geraniums that will add color and fragrance to your garden or indoor space. So go ahead, give it a try, and enjoy the beauty and elegance of these magnificent plants!
