Create Your Own Paradise with Vibrant Annual Geranium Varieties

We have gathered some stunning geranium varieties that work for most home garden spaces. 

What is a Geranium?

Geraniums prefer well-draining soil that is neutral to acidic. If your soil is too heavy, add peat, compost, or perlite to lighten it. Most geraniums varieties prefer a pH of 6.5, while some like Ivy and Regals prefer a pH of 5.3 – 6. 
Scented geranium oil is popular as a beauty aid. Use fragrant geranium leaves to make your own oil. Take pesticide free scented geranium leaves and put them in a jar filled with sesame or olive oil. Make sure the leaves are covered by the oil. Place the jar in a warm and sunny location for one week. Strain the old leaves and add new leaves to the oil. Repeat this process for 5 weeks. Store the oil away from bright sunlight. Be sure to monitor your skin after you apply geranium oil. It is safe for most people, but it may cause others irritations like a rash. 
The care of geranium plants is easy, but they offer an outsized impact for hanging baskets, standing containers, and outdoor garden borders.

This regal variety has a deep red geranium flower that is small and compact. The plant grows just 12 inches tall and perfect for container or delicate border edging. 
Most gardeners grow the pelargonium as annuals, though they will survive as perennials in certain warm climates. Even if you grow these plants as outdoor annuals, they can overwinter inside. Keep them inside during the coldest parts of the year and then bring them outside again in the spring.

Rose geraniums are a variety of scented geranium that is used in kitchen concoctions from food to scented oil. Use washed and pesticide free leaves to flavor sugar, cakes, cookies, summer drinks, simple syrup, and ice cream. 
 Most gardeners grow outdoor geraniums as annuals and bring them indoors to overwinter inside. When you plant geraniums outside, make sure temperatures are averaging around 75 degrees Fahrenheit during the day and 60 degrees Fahrenheit at night. This is for optimum growth. 

Geraniums are one of the best plants to propagate from stem cuttings. Cut a stem just below a node and use a stem that is around 4-6 inches long. Strip the lower leaves and put the cutting in potting soil. Place in an area with bright but indirect light. Water when the soil on the top becomes dry to the touch. You can also place the stem in just water. Roots will begin to develop in around 4 weeks. 
‘Calliope Dark Red’

When temperatures dip below 50 degrees or above 85 degrees growth is stunted. Some varieties will exhibit heat or low temperature stress with discolored leaves or a decrease in plant growth.

Conclusion

Put them in large pots to enhance your front entrance or spread them along a walkway. Wherever you plant them, geraniums will not disappoint. 
Geraniums require some fertilization to thrive, but too much fertilization will increase the foliage but decrease geranium flowers. Use an all purpose water soluble plant food in combination with thorough waterings. Mix 2 tablespoons of an all-purpose solution with a gallon of water.
