All of last summer, I left the plant outside to see if the leaves would grow back. It seemed to be doing great, with new leaves coming in regularly and the stalks were growing, too.
When I brought the plant back in for the winter, I began watering it myself based on what had been suggested here. I tried giving it a little more than a cup a day, and was making sure that the soil was staying moist (but not wet) about 4" beneath the surface of the soil. The plant is directly in front of a south-facing window.
But since the day I brought it in, there hasn't been any new growth at all. In fact, recently a few of the smaller leaves fell off.
Am I STILL watering it wrong? The plant is about 2-3' tall, 7 stalks, and in a pot that's about 12" in diameter. I put a thin layer of decorative gravel (crushed brick) on top of the soil over a year ago to keep my cat from peeing in it. I'm watering it just above the soil, a little more than a cup a day.
PS, I also had a goldfish tank, and they all died pretty quickly due to a high level of nitrates in my tap water (well water). Would this have an impact on the plant?
