Rooftop and Balcony Garden Options

Roof gardens are idyllic throughout summer; perennial plants in containers can be removed during winter to a less exposed position.

Small Gardens (Fox Chapel, 2016), by David Squire, offers guidance through the seasons for creating a thriving colorful sanctuary regardless of your space. Squire contributes his lifetime experience with cultivated and native plants with an interest in historical medicinal roles, folklore, and customs of plants. This excerpt is from “Choosing the Style” section.

It is surprising how much colour can be created on a balcony or roof, whatever its aspect. Pots, troughs and hanging-baskets packed with summer-flowering bedding plants are ideal during summer, while from autumn to spring reliance is mainly on small, evergreen shrubs and dwarf conifers. When tender plants are grown, these may have to be taken indoors during winter. Alternatively, a friend with a frost-proof greenhouse might be able to offer them sanctuary.

On Top of the World

Roof gardens are popular where the climate allows more than half the year to be spent on it. In other places, despite initial enthusiasm, the reality of a seasonal garden becomes apparent when icy winds roar across the site. Conversely, during summer the area may be exposed to strong, scorching sunlight, which may be ideal when attempting to gain an attractive sun tan but will shrivel plants which are not regularly watered. Nevertheless, the ability to garden ‘on top of the world’ has unmatched eye appeal.

Roof-Garden Ideas

Construct screens to create privacy as well as giving you protection from strong wind. In summer, temporary privacy screens may be all that is needed. Privacy screens are also essential to reassure neighbours they are not being spied upon; before problems arise, tell them about your plans.

In windy positions, it is best to rely on summer-flowering plants in troughs and tubs to create colour.

Construct a series of strong railings along the outer edges of the roof garden and then train small-leaved, variegated Ivies to grow over them.

Balcony Key Features

In cold and exposed areas rely mainly on summer displays from summer-flowering bedding plants. Use trailing, small-leaved, variegated Ivies to create more permanent colour.

Roof-Garden Caution

Check that the infrastructure is suitable and there is an easily accessible source of water. A combination of strong sunlight and breezes soon causes compost to become dry.

Making the Most of a Balcony

• For a colour contrast, secure pots of red or scarlet Geraniums (Pelargoniums) to the tops of white railings. At floor level, use a combination of trailing Lysimachia nummularia ‘Aurea’ (yellow flowers and leaves) and red Petunias. Let the Lysimachia trail through the railings.

• Fragrant displays in spring can be created from troughs or large pots of Hyacinthus orientalis (Hyacinths), in colours including white, rose-pink and soft blue. Plant them in autumn and await a magnificent, superbly fragrant display the following year.

• Several Lilies can be grown in pots on warm and wind-sheltered balconies.

Leisure Balconies

In addition to growing plants on balconies, don’t forget that they are leisure areas:

• Where the view allows and the balcony’s size is suitable, consider having a deck-chair and small table that can both be easily stored indoors when not in use.

• Low-intensity and unobtrusive lights provide another opportunity for making the best of a balcony after the sun has gone down.
