Today’s topic is a houseplant term: flagging.
The plant shown in this video is currently flagging. Flagging is a sign that a plant is thirsty — but it hasn’t yet reached the point of wilting. It’s a stage that occurs just before drooping.
When a plant is flagging, the leaves start to lose their shine and become slightly limp. The sheen fades, and the plant takes on a duller appearance. If you water your plant during this flagging stage, you can prevent long-term underwatering damage.
Some plants, like this pothos, bounce back easily after flagging — which is why it was used in this demonstration. Others may not recover so well. There are additional videos linked below that cover what to do if you missed this stage and your plant wilted.
Right before filming, this pothos was watered because it had clearly started flagging, and it was important to show you what that looks like. You’ll notice the leaves are a bit limp and lack their usual shine.
If you ever find yourself wondering why your plant looks “off,” check for signs of flagging. Touch the soil — if it’s dry, it’s time to water! Flagging is your plant’s way of waving you down and saying, “Please water me before I suffer irreversible damage.”
Now you know what flagging means and why it’s important to catch it early.
