Hi you asked about chalk soil last week . are you on a course? if you are then please let us know. it will make answering questions easier. I also notice you are in Canada, so the composition of your soils/geology is unknown to us.
hope someone else can help you.

Did 514352 also ask about clay soil, or did the thread just drift that way? Also asked about fertilizer for heathers. Very vague questions always make me think they're doing research for homework.
