This complete guide explains what trailing geraniums are, how they differ from upright types, where to grow them, and how to care for them so they flower continuously from late spring until the first frosts.
What Is a Trailing Geranium?
A trailing geranium is a pelargonium with a naturally cascading growth habit. Instead of growing upright, the stems spill over the sides of containers, producing flowers along their length.
Key characteristics include:
- Long, trailing stems
- Smooth, glossy, ivy-shaped leaves
- Single or double flowers
- Excellent performance in baskets and window boxes
Trailing geraniums are tender perennials, usually grown as annuals in the UK.
Trailing Geranium vs Upright Geranium
Although closely related, trailing and upright geraniums behave very differently.
Trailing geraniums:
- Cascade over edges
- Ideal for hanging baskets
- Smooth, waxy leaves
- More tolerant of wind
Upright (zonal) geraniums:
- Grow vertically
- Best for pots and bedding
- Soft, hairy leaves with dark zones
- Less suitable for exposed positions
Choosing the right type ensures the best display.
Types of Trailing Geraniums
Trailing geraniums are available in many colours and flower forms.
Single-Flowered Trailing Geraniums
- Five-petalled flowers
- Better resistance to rain
- Excellent for exposed sites
Double-Flowered Trailing Geraniums
- Rose-like blooms
- Very decorative
- Slightly more sensitive to prolonged wet weather
Colours include red, pink, white, salmon, purple, lilac, and bi-colours.
Are Trailing Geraniums Perennial?
Trailing geraniums are tender perennials.
- They do not survive frost outdoors
- Usually grown as annuals
- Can be overwintered indoors
With winter protection, plants can be kept for several years.
Where to Grow Trailing Geraniums
Trailing geraniums perform best in containers.
Ideal locations include:
- Hanging baskets
- Window boxes
- Balcony planters
- Raised containers
Planting them high allows stems to trail freely and evenly.
Light Requirements
- Prefer full sun
- Will tolerate light shade
- More sun means more flowers
At least 6 hours of sunlight per day gives the best results.
Soil and Compost Requirements
Trailing geraniums need:
- Free-draining compost
- Moderate fertility
- Containers with good drainage holes
Avoid heavy or waterlogged compost, which leads to poor growth and root problems.
Watering Trailing Geraniums
Correct watering is crucial.
- Water when the compost surface feels dry
- Avoid letting pots sit in water
- Reduce watering in cooler or wet weather
Trailing geraniums cope better with slight dryness than constant moisture.
Feeding Trailing Geraniums
To keep plants flowering heavily:
- Begin feeding once plants are established
- Use a high-potash liquid feed
- Feed weekly throughout the flowering season
Avoid high-nitrogen feeds, which encourage leaves at the expense of flowers.
When Do Trailing Geraniums Flower?
Trailing geraniums flower:
- From late spring
- Throughout summer
- Until the first autumn frosts
With regular feeding and deadheading, flowering is continuous.
Deadheading and Maintenance
Routine care improves appearance and performance.
- Remove spent flower heads completely
- Trim back excessively long or straggly stems
- Encourage branching by pinching tips
This keeps plants tidy and full.
Do Trailing Geraniums Need Support?
No support is needed.
- Stems trail naturally
- Flexible growth resists wind damage
- Ideal for exposed locations
They are one of the most wind-tolerant summer bedding plants.
Common Problems
Poor Flowering
- Not enough sunlight
- Overfeeding with nitrogen
- Irregular feeding
Yellowing Leaves
- Overwatering
- Poor drainage
- Cold conditions
Pests
- Aphids
- Whitefly
Good airflow and correct watering prevent most issues.
Can Trailing Geraniums Be Grown Indoors?
Trailing geraniums can be kept indoors short term.
- Best in very bright rooms
- Useful for overwintering
- Flowering indoors is usually reduced
They perform best outdoors during the growing season.
Overwintering Trailing Geraniums
Trailing geraniums can be overwintered to save plants for next year.
How to Overwinter
- Bring plants indoors before frost
- Place in a bright, frost-free position
- Reduce watering significantly
- Do not feed during winter
Plants can be pruned back in spring to encourage fresh growth.
Propagating Trailing Geraniums
Trailing geraniums are very easy to propagate from cuttings.
Taking Cuttings
- Take cuttings in late summer or early autumn
- Use healthy, non-flowering shoots
- Allow cut ends to dry for a few hours
- Insert into free-draining compost
Cuttings root quickly and produce identical plants.
How Long Do Trailing Geraniums Live?
- Treated as annuals outdoors
- Can live several years if overwintered
- Best displays come from young, vigorous plants
Many gardeners replace plants annually for maximum impact.
Are Trailing Geraniums Worth Growing?
Yes. Trailing geraniums are valued because they are:
- Easy to grow
- Long-flowering
- Ideal for baskets and window boxes
- Wind tolerant
- Reliable in summer displays
Few plants offer such colour and performance with minimal effort.
Final Thoughts: Trailing Geranium
Trailing geraniums are among the best plants for hanging baskets and container displays, combining cascading growth with months of vibrant colour. With sunshine, free-draining compost, regular feeding, and sensible watering, they will reward you with continuous flowering from late spring until autumn.
Whether grown as annuals or overwintered for future seasons, trailing geraniums remain a dependable and eye-catching choice for gardens of all sizes.
