Repotting involves moving a plant from its current container to a slightly larger one. For hanging plants, this process provides fresh nutrients and space for root expansion, preventing the plant from becoming root-bound and suffering from nutrient deficiencies. The unique challenge lies in managing the long, delicate vines and accessing the pot while minimizing the mess associated with handling soil. Approaching the task with organization and specific techniques ensures the plant remains healthy and the process is manageable.
Recognizing the Need for a New Home
A clear sign that the roots have exhausted their space is when they begin to protrude noticeably from the pot’s drainage holes. Another indicator is a significant change in the soil’s moisture retention, requiring daily watering because the root mass has displaced most of the available potting mix. Stunted growth, despite adequate light and fertilization, can also signal that the roots are restricted and unable to support new foliage production. Finally, a white or crusty accumulation of mineral salts around the rim or on the surface of the soil suggests a need for fresh substrate. Ideally, repotting should be scheduled for the early spring, just before the plant’s active growing season begins, allowing it to recover quickly.
Gathering Materials and Preparation
Preparation streamlines the process and helps contain the mess before the plant is even touched. The new container should only be one to two inches larger in diameter than the old one, as an excessively large pot can retain too much moisture and lead to root rot. For hanging plants specifically, selecting a lightweight material like plastic is advantageous because the combined weight of the plant, soil, and container must be supported by the ceiling hook. A fresh, well-draining potting mix is necessary, often containing perlite or coco coir to ensure aeration. Laying down a protective layer, such as a large tarp or newspaper, directly beneath the work area will catch any spilled soil, and having clean pruners, a small trowel, and gardening gloves ready ensures all necessary tools are within arm’s reach.
Step-by-Step Repotting for Trailing Plants
Preparing the Plant and Vines
Begin by thoroughly watering the plant approximately 24 hours before the intended repotting time; this hydrates the roots and helps the root ball slide out cleanly. Before attempting to remove the plant, gently untangle the vines and secure them by draping them over a nearby object, like the back of a chair or a tall box, keeping them out of the way.
Removing and Inspecting the Root Ball
To remove the plant from its old container, place one hand over the soil surface, positioning your fingers around the base of the stems, and then carefully invert the pot. If the plant does not slide out readily, a light tap on the pot’s bottom may be necessary to loosen the root ball. Once freed, inspect the roots for signs of being root-bound, which appear as a dense, matted coil around the perimeter. If the roots are tightly bound, gently tease them apart using your fingers or make several shallow, vertical cuts—a process known as scoring—on the sides of the root ball to encourage outward growth.
Placing in the New Container
Place a small amount of new potting mix in the bottom of the new container, ensuring the top of the root ball sits about an inch below the rim. Carefully fill the space around the root ball with fresh soil. Tap the pot gently to settle the medium and eliminate large air pockets. Ensure the plant is not buried any deeper than it was in its previous pot, as burying the stem can lead to rot.
Settling the Plant After Repotting
The first step is to water the newly potted plant thoroughly until water freely drains from the bottom, ensuring the entire new soil volume is saturated and the roots have immediate access to moisture. This initial heavy watering also helps the soil settle completely around the root system. After repotting, the plant needs time to adjust to its new environment and repair any minor root damage sustained during the process. Avoid applying any fertilizer for at least four to six weeks, allowing the roots to focus their energy on growth rather than nutrient uptake. Place the plant in a location with bright, indirect light, keeping it away from direct, harsh sun for the first week or two to prevent leaf scorch while the root system stabilizes.
