Herb wheel planters allow you to plot out a well-organized herb garden, whether you grow a large or small variety of plants. The wheel consists of a circle divided into equal, pie-shaped slices with a different herb planted in each slice. Purchased planters are similar to raised beds, but you can set them in the garden or on a patio. You can also create your own wheel planter by using edging to create the circle and divide it.
Fill a raised planter with a loose, soil-less potting mix containing peat moss, compost and vermiculite. Spread 2 inches of compost over a wheel installed in a regular bed and work the compost into the top 6 inches of the soil.
Water the soil until it is evenly moist throughout. Water wheel planters until the excess moisture begins draining from the bottom and water beds until the top 6 inches of soil is moist.
Lift the herb plants out of their nursery pots. Plant them in the wheel bed or planter at the same depth they were growing at in their nursery pot. Plant only one type of herb per section. Follow the spacing recommendations on the label for each particular type of herb.
Water raised wheel planters every two to three days, or when the top 1 inch of soil just begins to feel dry. Water bedding wheels once or twice a week, or often enough to keep the top 6 inches of soil moist.
Fertilize wheel planters once monthly throughout the growing season with a soluble, balanced fertilizer. Follow the package recommendations for application amounts. Bedding wheels rarely require fertilization.
