I have some very basic questions I would love answers to.

1) How am I supposed to tell if my soil is "well drained" or not?
And if it's not, how do I make it so?

2) If a particular plant requires part shade, how much actual time is
that daily approximately?

3) If a certain plant requires "sandy" soil-should I assume that means
I need to add sand to my soil? If so, how much is adequate? If not,
what does "sandy" soil actually mean?

I would appreciate any help you can provide. Any suggestions, links,
etc. are welcome!!

Thanks,
Rebecca
