Every good herbs garden design book advises a designer gardener to first take your squared paper and in fact, it is a good idea to draw the plan to scale. The size of the beds is much more easily appreciated. The spaces between them can be better compared to the dimensions of the beds, and the proportions of the various plants can be correctly assessed so that mistakes in juxtaposition can be adjusted.
Better still, if you’re anything of an artist, is to transpose your scale plant to a three-dimensional drawing, preferably colored, showing it as it will be in three or four years, a time when the perennial plants are mature. The shade of blue symbolizes calm, tranquility, and relaxation. Herbs should be evaluated according to their unique attributes and uses.
Herbs Garden Steps in Designing
-
Assess your soil:
Is it well-drained (sandy, shingly, gravelly, and chalky?
Does it hold water and feel sticky when wet, cracking badly when dry (predominantly clay or silt)?
Is it dark-colored, spongy when wet, and dusty when dry?
How does it react to a pH test (acid or alkaline)?
Does it contain organic matter (material floating on the surface of a solution of soil)?
-
Assess Your Site
Which parts are sunny-shady?
Does it get wind, and if so, where from (north, south, east, or west)?
Is it likely to retain frost and collect snow in the winter?
Is it sheltered by walls/fences/hedges?
Is the garden close to the sea?
What is the average winter and summer rainfall?
Where does the water lie in the wells?
-
In light of the answers to these questions, select your herbs. Whatever choice of herb you settle on, before you start to mark the places for them on you’re paper plan, make sure you know what their final size will be when they are mature. The adult height and width are important facts with which you can plant without crowding or spacing; if the soil is a well-worked heavy one, allow for extra growth. The converse is seldom true since several herbs grow naturally in poor, dry soils.
-
Make a rough diagram of what you’re designing and determine whether it is appropriate to the size of the site; e.g., a herb border on the grand scale will not be successful in an area of 3 x 3 (10 x 10 ft); in other words, the proportions of the design should be such that there is room to make the most of them in the area concerned.
-
Select your plant according to your needs and the dictates of the soil and site, as determined by your assessment.
-
Enter the name on the diagram in your preferred arrangement, taking into account height as well as spread, whether they’re evergreen, perennial, annual, flowering, or non-flowering. At this stage, it can help to trace the design on the site in an outline with the help of chalk rope, string, or the garden hose, and to use canes stuck in the soil to indicate the final height of plants.
-
Measure the area exactly and scale it down for transfer to squared paper. A large scale would be 1.2 cm (1/2 in) per 30 cm (12 in), but if you want to mark all the plants in all the beds, it’d have to be of the order of 5 cm/30 cm (2 in/12 in).
-
Mark the beds and borders on it to the dimensions required, in the required positions.
-
Write the names of the plants where they fit into the pattern and draw a circle around them to indicate the extent of their final spread.
-
Decide on the number of plants and the seeds required and order accordingly, unless you’re planning to plant up from different sources.
