girliemac,
If you double click on the blue text bill provided in his post and read down about 3/4ths of the way it will tell you precisely what, and how much, to add to your soil to get the proper pH for your different
plants.
If you can not find the information I can cut and paste it into a post on this string for you.
trying to add the correct amount of "humus" could be a long and error ridden project that could cost you many
plants. This is assuming that you are planning to
plant them outside.
If you are container gardening I would suggest that you buy the correctly amended potting soil for your type of
plant. I'm sure you have noticed that there is special potting soil for
succulents,
cactus, violets, orchaids(sp) and probably more besides. Also it might be wise if it is container gardening to know how much room the
plant likes to have. Many will not bloom if they are not somewhat root bound.
This is just some of the information I have been trying to gather also; because, I am a new gardener and know nothing other than what I have read on this site. Or should I say that I have been learing that just about everything I thought I knew was exactly backwards or just totally wrong.
It definitely makes me feel
