Catnip

Use catnip in a sunny border, herb garden, or dedicated container where its broad habit has room to develop without closing off a path. Set it behind short edging plants or at the outer side of a vegetable bed, keeping a clear reach-in edge for harvesting and cutting back. It can be grouped near cabbage, squash, tomato, eggplant, or carrot plantings, while still leaving those crops their own working space.

Plant catnip 2 feet apart, center to center, for a connected planting that quickly fills its allotted strip. A mature plant can spread about 3 feet wide, so allow its foliage to knit between plants and avoid placing it tight against paths, bed corners, or slower-growing neighbors. In a single row, reserve a band at least 3 feet deep and maintain access from one side for trimming and harvest.

Give catnip a full-sun position with well-drained soil, especially in beds that dry between rain or irrigation cycles. Its tolerance of dry conditions makes it more suitable for a leaner, free-draining border than for a persistently wet pocket. In hot, humid settings, a location with afternoon shade can reduce heat exposure while preserving a bright growing site.^[1][2]

Flowering and harvest extend from late spring into early fall, so leave room for catnip to remain in place while nearby seasonal crops are changed out. Trim after the first flowering flush to keep the clump more compact and encourage continued bloom. Plan this task from a nearby path or bed edge rather than relying on access through adjacent plantings.^[1][2]
