A herb garden container is a useful and economical way of having an endless supply of herbs all year round. Place it inside or outdoors to decorate a particular spot and allow you to pinch fresh herbs whenever needed. Such gardens provide the portability of being moved inside during the winter. Most herbs have shallow roots, making them suitable for containers. Make a simple rectangular container from wood to fit the designated spot.
Cut four 1-inch-thick wooden boards to form the walls of the rectangular herb garden container. Keep the front and back identical in length, width and height, and the short sides identical. For the base, cut a length of wood identical in width to the sides but as long as the front.
Lay the front on a flat surface and hold a side piece flush against its end. Butt the joint and drill two screws to join the L-shaped structure. Repeat the process to secure the back to the other short side.
Arrange the pieces on a flat surface so the long side of one rests against the short side of the other, forming a rectangle. Drill screws to join them together.
Flip the container and lay the base piece over the four sides. Secure it in place by drilling two screws on each short side and four on each long side. Also drill 1/2-inch-wide drainage holes over the base board, spaced 5 inches apart.
Spread a 1-inch layer of gravel or broken crockery shards over the base of the container to help drainage. Herbs will get root rot without good drainage. Place the container in a sunny spot indoors, or one that receives at least six hours of direct sunlight daily.
Mix equal amounts of good quality potting soil and organic compost in a bucket and pour into the container until 2 inches below the rim.
Insert a stick into the soil to make a hole for each seedling before lowering it. Make sure you cover the root ball completely. Space seedlings 2 to 3 inches apart. Plant taller herbs, such as fennel and dill, in the back, and cascading thyme or tarragon to the front or sides. Press the soil around the base of each seedling with your fingers. Water the container well.
