Step 5: When all else fails, turn to technology
If you just can’t seem to hold it together, there's always good ol' technology to keep you from going on a serial plant-murder spree. If the problem is simply staying on a watering regimen, an easy fix is to set up a recurring alarm or calendar reminder on your phone to keep you on your toes. If you're having trouble gauging how thirsty it is with the knuckle trick, these $6 digital water sensors should lend a hand.
If your place isn't providing the natural light required to sustain the plant, there are all manner of affordable LED bulbs you can set up encourage hot, hot photosynthesis in even the darkest corners.
There are also a growing number of smarthome products dedicated to keeping houseplants alive, including the ingenious Flower Power system—a Bluetooth-enabled sensor that constantly monitors the soil and syncs with your devices to alert you of any and all health aspects. Soon, the company that makes it will be releasing an even more advanced system, complete with mini irrigation systems and pots that water themselves .
