Containers: summer selection

Introduction

For successful summer displays, choose plants that flower over a long period of time, respond well to deadheading and are tolerant of container cultivation. A wide range of suitable plants should be available in most garden centres from late March onwards. However, don't plant them out until the risk of frost has passed in your area.

Practical considerations

When planting up summer containers remember;

• The mainstay of summer containers are tender perennials, often referred to as 'patio plants'. Those such as fuchsia can overwintered in the greenhouse as plants or rooted cuttings or bought fresh each year
• Annual bedding plants are also good candidates and include nasturtium and pot marigold
• It is possible to use hardy perennial plants, such as lavender, which can eventually be planted out in the garden
• Choose a focal plant such as a structural shrub or annual climber grown on a small tripod for the centre of the scheme
• Surround the focal plant with a mix of upright bedding plants and some that trail over the side of the container. Plant at least three of each
• Link the scheme together by repeating some of the same plants in each container and consider restricting the colour scheme
• Combine plants that have similar requirements; most summer bedding plants do best in full sun but some, such as begonias and tobacco plants, will tolerate light shade
• Where daily watering is impossible, consider drought-resistant plants such as cacti and succulents
