My wife and I just spent the evening planting out tomatoes. As i planted each one i buried a 2lt bottle cut in half down the side and across so that there is a reservoir in the bottom. As i water them the idea is that some of the water will get trapped and the plant can draw from this. Ive also laid a black plastic barrier to prevent weeds and to retain even more moisture.

What are other members doing to reduce the amount of watering needed?
