Catmint, scientifically known as Nepeta, is a robust perennial herb valued in gardens for its fragrant foliage and extended bloom period. Gardeners often relocate or divide this hardy plant to manage its spreading habit or to propagate new specimens. While Catmint is generally tolerant of being moved, transplanting disrupts the root system. Proper timing and technique are essential for a smooth transition and successful relocation, requiring attention to the plant’s needs before, during, and after the move.
Optimal Timing for Moving Catmint
The most favorable periods for relocating Catmint align with its dormant or semi-dormant cycles: early spring or late summer into early fall. Transplanting in early spring, just as the plant begins to show new growth, allows the root system to establish itself before the stress of summer heat arrives. The cool soil and moderate air temperatures encourage root development without the plant having to support extensive foliage growth. Late summer or early autumn is an alternative ideal time, provided the move occurs several weeks before the first hard frost. Avoid moving Catmint during the peak heat of summer or when the plant is actively flowering, as high temperatures and increased metabolic demand place excessive strain on the plant.
Pre-Transplant Preparation
Preparation begins by selecting a new location that provides full sun to partial shade and features excellent drainage. If the existing soil is heavy clay, amend the site with organic matter like compost. Dig the receiving hole two to three times wider than the Catmint’s root ball, but only as deep as the root ball itself; this wide hole encourages new feeder roots to spread easily and promotes rapid establishment. Thoroughly water the plant at its original location 12 to 24 hours prior to the move. This pre-hydration ensures the root ball remains cohesive and saturated, protecting the fine root hairs from drying out during the transfer process.
Step-by-Step Transplanting Technique
The physical process of lifting the Catmint must be executed with precision to retain as much of the root system as possible. Use a sharp spade to cut a wide circle around the plant, aiming to capture a generous root ball that extends beyond the main stem. Carefully work the spade underneath the root ball to sever deeper roots, then gently lift the entire mass out of the ground, using a tarp or wheelbarrow for transport. Before placing the plant into the prepared hole, trim back the existing foliage by up to one-third. This pruning reduces the leaf surface area that loses water, lessening the demand on the newly disturbed root system. Position the plant in the center of the new hole, ensuring the crown is level with the surrounding grade, and backfill with amended soil, lightly tamping to remove air pockets.
Ensuring Successful Recovery
Immediately following transplanting, the Catmint needs a deep and thorough watering to settle the soil firmly around the roots. This initial drenching helps eliminate any remaining small air pockets that may hinder root-to-soil contact. For the next few weeks, maintaining consistent soil moisture is crucial for the plant’s establishment. Monitor the Catmint closely for signs of transplant shock, such as wilting or yellowing leaves, and keep the soil consistently moist but never soggy. If the weather turns hot and sunny, provide temporary shade during the hottest part of the day to prevent excessive moisture stress until new growth is evident.
