Do perennial geraniums spread?
Over time, perennial geranium plants will spread and form clumps. Herbaceous perennials that flower in early summer, such as hardy geraniums (pictured), alchemilla and stachys, can be cut to the base as soon as the main flush of blooms starts to fade. In an early season, this will be towards the end of June.You can take geranium cuttings at any time of year, but you’ll probably have more success in summer, when there’s plenty of light and warmth. If taking cuttings at other times of year it’s a good idea to use a heated propagator and grow lamp to increase your chances of success.Geraniums are appreciated for their long blooming season that starts in spring and can last into fall. If plants are kept above 45 to 50 degrees, they may also bloom in winter to early spring.Early-flowering perennials such as geraniums and delphiniums are cut to near ground level after flowering to encourage fresh foliage and late summer flowering.

How do I know if my geranium is annual or perennial?
Although most geraniums are grown as annuals, they are perennials in Zones 10-11. Bring them indoors to overwinter, if you like, and then replant them outdoors in spring, or they can bloom indoors all year long if they get enough light. Mostly grown as annuals, geraniums are short-lived perennials when overwintered in Zones 9-11 or indoors. They last for about two years when properly cared for. For new, healthy plants every spring, consider propagating them from cuttings.The true geranium lifespan, as long as it’s cared for well, can be many years long. They can also be easily overwintered. Certain other varieties, such as Geranium maderense, are biennials that will survive most winters but have a lifespan of only two years.Before the frosts arrive, dig up your annual geraniums. Knock the soil off the roots and snip off any flowers or flower buds. If the soil was damp, allow the plants’ roots to dry off for a few hours before proceeding to the next step. Grab a cardboard box that is large enough to accommodate your prepared plants.Geraniums benefit from regular feeding to promote healthy growth and plenty of vibrant blooms. Use a quality all-purpose feed like Miracle-Gro’s All Purpose Concentrated Plant Food every 2 weeks or so. Be sure to dilute as the packaging directs.Ideal growing temperatures for geraniums are 70 to 75 degrees during the day and 60 to 65 degrees at night. Thoroughly water the geraniums when the soil surface is dry to the touch. If using a commercial potting mix containing a slow-release fertilizer, fertilization probably won’t be necessary.
Is perennial geranium sun or shade?
Growing hardy geraniums is simple—plant in well-drained soil with sun to partial shade, and enjoy their resilience and vibrant flowers season after season. Geraniums have the ability to survive for most of the winter without soil. Dig up the entire plant before frost and gently remove the soil from the roots. Place the plants inside open paper bags or hang them upside-down from the rafters in a cool, dark location for the winter.To bloom abundantly and continuously, geraniums need watering regularly. Use your finger to find out whether you need to give them a drink. If the soil feels dry and warm to a depth of 2cm, your plants need more water.perennial geraniums vary in bloom time, flower color, flower size, height, leaf color, and habit. Depending on species/cultivar, most flower for 2 to 4 weeks, beginning in mid to late spring and finishing sometime in summer.Geranium cuttings can also be started directly into the soil outside, but you need to start them in a partial sun area when temperatures are warm, not hot and keep the soil consistently moist, not sodden. Before you try this, allow the cuttings to sit out for 3 days so the cut end forms a callus.Geraniums are often grown as annuals and are composted at the end of summer. If you have room in a frost-free place, it’s worth trying to keep them over winter. To overwinter geraniums, lift plants that are in garden soil or large pots and pot them into a smaller pot. This should be done before the first frost.

Hardy Geraniums are reliable, long-flowering, easy-to-grow plants. A popular perennial, which often flowers for many months, and are ideal planted over a garden wall or at the front of a sunny border.

If you’re up for a challenge and have pelargoniums with tough, woody stems, you could try your luck at overwintering them as bare-rooted plants. Before the first frosts, lift plants from the ground or pot and shake off excess soil or compost from the roots,” the RHS suggests. There isn’t a ‘best’ time to take cuttings from members of the pelargonium family because they have no dormant period and grow for twelve months of the year. However, success depends on being able to supply good light and warm compost.
