A knot herb garden is designed to look visually stunning from either afar or from above. Knot herb gardens are often designed in the shape of a Celtic knot and have to be maintained regularly to preserve their appearance. Knot herb gardens emerged during the Queen Elizabeth I reign and were aimed at displaying the wealth of their owner. Creating your own knot herb garden can be relatively easy and also very enjoyable.
Step One - Design
The first step is to design your knot garden. Plan the design on paper in order to gain a rough idea of where you want to place the herbs. Knot gardens are more traditionally designed to fit into a square or rectangle so you will be designing with straight lines. It might also be worth researching Celtic knots. A Shamrock-design knot is a relatively simple design but will look exceptional in many gardens. Remember to measure your garden before you start planning your design so that you will be working to scale.
Step Two - Herb Selection
Now that your design is complete, you will need to select the herbs you want to use to create the garden. Try to choose plants that will flourish in your soil type and climate. Sage, rosemary, lavender and parsley require a well-drained soil with plenty of sun. To add some varieties to your design, try incorporating vegetables and flowers into your garden. You can also try mixing onions, mint and basil with tomatoes, peppers and carrots.
Step Three - Start Planting
To start planting the design into your garden, use a couple of pegs and string to mark out the straight lines of your design. You can then start to place the plants in position. When you are ready to start planting your herb garden it is best to work in smaller sections and try to keep to the straight lines of your design and the position of the plants.
A knot herb garden works better if you keep the annual herbs close together. You can also add texture to your herb garden by giving the appearance of their growing over and under each other. To accomplish this, just prune the underside of one plant and the top growth of the other plant.
Step Four - Add a Border
If you want to add color to the borders of the design and make it look more intricate and defined, you can use different colored mulches or stones. These can be purchased from a local nursery or from most garden centers. The advantage of adding mulch or stones to your garden is that the area will require less care--sometimes only needing care once a year.
Step Five - Maintenance
The key part of having a knot garden is maintenance. The plants and herbs will need to be manicured regularly to ensure that they not only stay healthy but that your design continues to look defined, Maintaining your garden will also prevent the plants from growing over each other.
