Whether you're in the Midlands like me or elsewhere in the UK, growing verbena in pots can add a splash of vibrant colour to your garden or patio. It's a straightforward process when you know how to provide the right conditions for these lovely blooms.
Quick Answer
To grow verbena in pots, choose a well-draining potting mix, ensure your container has drainage holes, and place it in full sun. Water regularly but avoid waterlogging.
Choosing the Right Container
When growing verbena in containers, the first step is selecting the right pot. Choose a pot that's at least 30 cm in diameter with good drainage holes. This size gives the roots ample space to spread and prevents water from stagnating.
Soil and Planting
Verbena thrives in well-draining soil. A general-purpose potting mix with added sand or perlite works well. Fill your container with this mix, leaving about 2.5 cm from the top. Plant your verbena seedlings or young plants, spacing them about 20 cm apart if you're planting more than one in a larger container.
Monthly Care Calendar
| Month | Activity | Notes |
|---|---|---|
| March | Planting | Start indoors to get a head start on the season. |
| May | Move outside | After the last frost, move pots to a sunny spot. |
| July | Deadhead | Regular deadheading encourages blooms. |
| October | Pruning | Trim back to maintain shape before winter. |
Watering and Feeding
Verbena prefers consistent moisture but dislikes soggy roots. Water your plants when the top 2.5 cm of soil feels dry to the touch. During the growing season, feed every two weeks with a balanced liquid fertiliser to promote healthy blooms.
Positioning and Light
These sun-loving plants flourish in full sunlight. In the Midlands, where we can have our fair share of cloudy days, try to position your pots where they’ll receive at least six hours of direct sunlight daily. If your garden is shaded, consider moving the pots around to catch more light.
Benefits of Growing Verbena in Pots
- Flexibility to move pots to catch the best sun.
- Control over soil quality and drainage.
- Perfect for small gardens or patio spaces.
Common Issues and Solutions
Verbena can occasionally suffer from mildew, particularly in humid conditions. Ensure good air circulation around the plants and avoid overhead watering. If mildew appears, remove affected leaves and consider using a fungicide.

How often should I water potted verbena?
Water when the top 2.5 cm of soil is dry. This might be more frequent in hot, dry weather.
Do I need to deadhead verbena?
Yes, regular deadheading encourages continuous blooming and keeps the plant tidy.
