Lavender is both a useful and an attractive herb. This perennial shrub-like plant has silver-green foliage and produce spikes of small purple, aromatic flowers in early summer. Grow lavender as an ornamental or use the dried flowers in tea, potpourri sachets or in flower arrangements and crafts. Lavender is also used to add color and flavor to baked goods. Plant lavender in a containers and bring the color and fragrance of these plants to patios and other outdoor living areas. You can also grow lavender in pots if you don't have a suitable garden bed.
Use a pot that is 1 to 2 inches larger in diameter than the lavender's root ball and has at least one drainage hole in the bottom. Lavender prefers being slightly crowded in the pot, according to Colorado State University Extension.
Combine a slow-release, balanced fertilizer and 1 tbsp. of agricultural lime with the potting mix. Apply the fertilizer at the rate recommended on the package for the amount of potting soil you are using.
Place 2 inches of a well-drained, light potting mixture, such as a peat- and vermiculite-based soilless potting mix, in a pot. Set the lavender plant on top the potting mix and add additional mix as necessary to elevate the top of the root ball so it sits 1 inch beneath the rim of the pot.
Fill in around the root ball with additional potting mix until the soil level is even with the top of the root ball. Firm the potting mix around the plant with your hands.
Water the lavender after planting until the excess moisture runs freely from the bottom of the pot. Check the moisture in the pot every two to three days and water lavender when the top 1 to 2 inches of soil begins to feel dry.
