Red Geranium Growing Tips

The red geraniums that most gardeners grow are annual plants, which means they only last for a year and then they die. You can plant geraniums every year in your garden and enjoy their colorful blooms all summer long. Most geraniums grow well in USDA Plant Hardiness zones 3 to 11, including the ever popular red geranium.


Plant red geraniums in well-drained loam. Adding compost to your soil will give it extra richness. Work the compost into the soil before you plant the geraniums. Be sure to plant geraniums after the last frost has passed.


Red geraniums need full to partial sun in which to thrive. Make sure your red geraniums get between six to eight hours of sunlight per day. Plant them in an area that is not shaded over by trees or fences.


Red geraniums need fertilizer every two weeks. A fertilizer such as 20-20-20 that is water soluble will work well with geraniums.


Red geraniums need the soil to be on the dry side. Water geraniums well when the soil is dry, but allow the soil to dry out in between waterings. Overwatering geraniums may kill your plants.


Deadhead any spent blooms as they occur during the growing season. Trim off any dead or diseased foliage as it occurs as well.
