Shallow Soil
Scatter seed on rocky ground, allow the rain and sun to do their work and just watch the little plants burst into life. But for how long? Without a depth of soil, water will not be retained; the roots will not find enough resources to support the plant against the heat of the day, the cold nights or the storms. The climatic testing will be too much for the little thing; and the promising start will be shamed as the plant withers away.
