Maintaining Geranium Blooms from Summer to Fall: A Guide for Continuous Bloom
================================================================
Geraniums, with their vibrant colours and sweet scents, are a popular choice for many gardeners. To keep these plants blooming longer, here are some essential care tips to follow.
Firstly, regular deadheading is crucial for extending the blooming period of various geranium varieties, such as Zonal, Ivy, Scented, and Regal/Martha Washington. This involves removing spent or wilted flowers before seed formation, which redirects the plant's energy into producing new blooms. Deadheading should be done weekly or as soon as flowers begin to fade or brown[1][5].
Providing adequate sunlight and well-draining soil is also essential for keeping geraniums blooming. These plants thrive in full sun and nutrient-rich, moist but well-drained soil, which supports continuous flower production[4]. Mulching geraniums can help the soil retain more moisture, reducing watering requirements.
Maintaining plant health is another key factor. Removing discolored or dying blooms and stems keeps the plant vigorous and reduces disease risk[1]. For hardy types like cranesbill geraniums, shearing plants lightly after the first bloom flush encourages fresh growth and more flowers later in the season[5]. Using garden snips or pruners helps make clean cuts that reduce disease chances compared to pinching by hand[1].
While specific varieties may have slightly different care needs, these general practices apply widely to keep geraniums blooming longer through summer and until fall frost.
Watering is another crucial aspect. Consistent watering is key to encouraging geraniums to keep blooming, but avoid overwatering to prevent root rot. Check the soil moisture regularly, and water when the top 1-2 inches feels dry.
As fall approaches, it's important to switch to a fertilizer with a higher potassium content to encourage blooming over foliage growth. Geraniums prefer soil to be a little on the dry side and well-draining.
Lastly, it's essential to protect geraniums from frost. Geraniums are not frost-hardy, and a light frost can damage the plants. Move potted plants to a more sheltered location overnight or cover plants in borders with a frost cloth during cooler autumn nights.
By following these care tips, you can extend the blooming period of your geraniums, ensuring a beautiful garden throughout the summer and well into the autumn.

Incorporating adequate sunlight and well-draining soil into your home-and-garden arrangement, along with proper deadheading, can enhance the home-and-garden lifestyle by prolonging the blooming period of your geraniums. Regularly removing spent flowers before seed formation, maintaining plant health, and using garden snips or pruners help in creating a garden that remains vibrant and full of colour throughout the summer and well into the autumn.
