Grow Guide Conditions:
Catnip grows to a height of three or four feet, and features downy, light green foliage with small lavender flowers that grow on spikes up to five inches long. Catnips grow well in almost any soil, but does best in a moderately rich loam that is well-draining. It's aroma increases when grown in sandy soil or via the hydroponic method. It will grow acceptably in either sun or shade.
Grow Guide Seed:
Plant seeds directly in the garden in spring. Catnip seeds can be sown outdoors only during the spring. If you're planting seeds directly into your outdoor garden, sow them as soon as any threat of frost has passed. Bury seeds 1/8 of an inch beneath the soil and space them at least 15 inches apart. Catnip prefers full sun in most locations. If you live in a hot, dry climate, consider an area where plants will have some shade from the afternoon sun. It will still need at least six hours of full sun, but in locations in the south, the sun at its highest and hottest could damage leaves.

Grow Guide Harvest:
To harvest, trim down a stalk to its base, or just above a leaf joint, or cut off the whole plant at the base. Cutting just above a joint, or where a leaf or leaves spring from the stalk, will promote more rapid new growth. Air drying is the best drying method for preserving catnip leaves
