Over time, your plants' soil loses essential nutrients and the ability to hold water. While the soil is depleting, the plants' roots continue to grow, taking up more and more space in the pot. Soon, the plant becomes "root-bound" also known as "pot-bound." This combination of factors inevitably leads to a sick plant.
It is essential to houseplant health that you know when it's time to repot. Pull the plant out of the pot every so often to check on its needs and the condition of the roots. Here are a few telltale signs it's time to repot:
- The plant is "root-bound" (roots wind around inside of pot or poke out drainage holes).
- The plant is deformed or top-heavy.
- You notice the appearance of brown, unhealthy roots at the bottom of the root ball.
- The bottom leaves turn yellow and drop off or leaves are pale and dull.
- The plant wilts between normal watering.
- Water drains quickly through the soil.
For best results, repot once a year when plants are between flowering cycles, usually in early spring or early fall.
