When outdoor space is at a premium--whether within the confines of a terrace or in a small courtyard--construct a vertical herb garden to give each plant its own growing space. Vertical herb gardens make use of wall or freestanding vertical square footage that is often only used for wall art.
A vertical herb garden is a creative, space-saving way to add a garden where one could not exist if it were to occupy the space on the ground or floor. These gardens also add new ways to incorporate more live plantings into living spaces. They improve air quality and provide a functional way to eat fresh herbs without sacrificing valuable living space.
Vertical herb gardens give home gardeners a way to grow herbs and vegetables in a neat and low-maintenance way, without having to till soil, deal with weeds or worry about garden pests.
These gardening solutions position potting soil or growing material in vertically aligned, tiered compartments. Each row receives the same sun exposure as the next because each is only one-row-deep and not arranged on shelves with shaded depth.
Besides sun exposure, some vertical herb gardens maximize their tiered orientation by allowing water to trickle down from the upper compartments to the lower compartments.
Stackable pots are common vertical herb garden arrangements. The gardener stacks pots of all types in graduating sizes or arranges them on vertical pot stands.
Other ways to create a vertical herb garden include affixing wall pots to a wall in an artistic arrangement or using a shoe wall organizer, with each pocket a planter for the herbs.
Vertical herb gardens are also commercially available. The Urb Garden is a self-contained, compartmentalized garden system that incorporates a system of feeding the herbs and vegetables with liquid fertilizer produced from food wastes in the unit's composting container.
Growing vertically does not necessarily limit the herb garden's size. Vertical herb gardens can be as small as a few pots or even a single arrangement or as large as a full wall or even the entire exterior side of a building. Considerations with size include accessibility to the herbs, watering and nutrition requirements and the weight of the vertical herb garden on its supporting wall or its freestanding unit.
There are no major differences in the time that herbs grow in a vertical herb garden from traditional gardens and pots. Lighting, watering and nutrition are the main factors to be concerned with for any gardening arrangement. The herbs will grow as they normally would if they receive adequate amounts of these things.
