Long candle wicks are available in most craft stores for people who make their own candles.
If you do not have a self-draining pot, use this opportunity to plant the plant you have just uprooted into a self-draining pot. Place some soil near the bottom to replace any soil lost from the original pot.
This step will be slightly different for everyone, depending upon where you plan to place your plant while you are gone. You may use a drainage basket or a shelf inside, where the wick can fall unencumbered into the vessel.
