First of all, yes, you can have running water from your sink or tap anytime. However, that water is not free. While it isn’t prohibitively costly, it may be more than some people are willing to spend. Rainwater is free and plentiful, depending on the locality.
Secondly, following a nice rain, plants appear brighter and greener. The rain may have just washed away the dirt and dust, and the plant receives the nutrients it requires
Rain also has potassium, sulfur, and a range of minerals and bacteria beneficial to plants.
Next, nature makes rain distilled before it evaporates. As a result, it’s ideal for dissolving any salt backups in soils. Plants exposed to too much salt might make them grow stunted or even die.
Rainwater is an excellent technique to boost the soil’s quality and enhance the fertilizer you’ve applied.
Additionally, groundwater levels have dropped significantly in some locations due to current services and buildings. Rainwater collection can assist in restoring groundwater in your nearby region, making your landscapes healthier.
