does the tpye of water affect the growth of a plant?

This site talks about acid rain and plant growth. PH values in water has alot to do with plant growth and root development.

The best water that is easy to get is rainwater, particularly rain from a thunderstorm. There is a high level of dissolved nitrogen in it, and it's value in promoting growth is about double that of tap water.

Untreated well water is also good, as it doesn't have chlorine in it.

Another excellent plant water is pond water, such as would be found in a water garden or Koi pond. Lots of nutrients, no chemicals.

How much water and when is entirely dependent on the plant species. Some are easily killed with a little too much water, others actually want continuously wet soil. You need to consider light source as well. Plants are very sensitive to the kind and quantity of light, and each has somewhat different needs. Research both water schedule and light needs based on the plant species itself.

I've found in 40 years of gardening that amount of water is more important than any qualtity issue. Houseplants most often die from too much water, while outdoor plants sometimes don't get enough. Your local nursery or agricultural extension service can give you guidelines on correct watering for most types of plants. There are also many websites with help for beginners, as in the link below.

As a practical matter, using what comes out of your tap is most convenient and cheapest. Equally important is the right amount of sunlight for each type of plant, the appropriate soil ph (acid-base), and the right kind and level of nutrients/fertilizer.

You should just use tap water, dont use bottled water. Different plants need different amounts of water, you would need to find out what each plants water requirement is to be able to water correctly.

It usually dose not matter what water you give although alt water will kill the plants if they don't like salty soils.Just water the plants when the ground looks dry and/or they are starting to wilt.

City water is usually treated and might have alot of chlorine. If possible, let the water sit a day or so to allow the chlorine to disipate.

if you have hard water (well water, no chlorine), then it should be OK.
