Feeding roses
Two questions:
(1) When should one stop feeding roses?
(2) I have a lot of Miracid as a leftover from a previous garden which had
many rhodos and suchlike. Is it wise to use it as a rose feed?
Just to forestall one possible objection: I don't believe for one moment
that Miracid contains enough buffered acid to enable it to function as a
serious soil acidifier. A test with litmus paper shows it to be as near as
dammit neutral in a tap water solution.
