Builder's lime is a different thing altogether and is inactive on the
garden. I am surprised that so many people do not use lime. It is essential
where I garden in Plymouth as the soil will get 'sour' after too long
without it as we are acid anyway. It is also useful to put in the planting
hole to help prevent club root although the experts as usual dispel this
notion.
