How do you prevent the "indoor garden" from streaking on the furniture, spotting the carpet, and short-circuiting the computer? Here are some tips:

1. Foresight. When choosing a plant for indoors, imagine the worst watering day scenario. What is the plant's prospective location and what will be affected in cases of spill-over or drainage overflow (think: the carpet, table finish, computer equipment, books, filing cabinet)? Plan on setting the plant on a low-risk location until the watering routine is perfected.

2. Protection. Self-watering planters are still the best options for office foliage because drainage is never a problem. But if you don't have a self-watering planter the next best thing is a good drainage catcher. Deep catch basins or high-sided saucers prevent accidental over-watering disasters.

3. Double Protection. Water-resistant dinner placemats between the shelf and the water catcher will help ensure that the rare spill over won't end up tarnishing the hardwood furniture. Mats will hold light spills from flowing off and dripping.

4. Calibration. Minding and remembering how much water a specific planter absorbs in one watering session will help minimize future spills and drainage overflows. Water gently and all around the plant to monitor the rate of drainage.
