I've never tried growing tomatoes before and I recently went out and bought a tomato plant for my balcony. I initially re-potted the plant in too small a planter, so I re-re-potted it a week later. Each time I watered thoroughly, perhaps too thoroughly, and also added a bit too much fertilizer, which I later attempted to wash away by (yes) more watering. Now, 2 weeks later, all the leaves are wilted and the tomatoes that started growing have stopped getting bigger. I tried draining the soil by lifting up the tomato plant and replacing wet soil that didn't yet have any roots with fresh, relatively dry soil.
Is there anything else I can do to stimulate this plant back to life?
