Feeding - the best time to fertilize magnolias is in late winter or
earliest spring. Use a 'rose type' fertilizer when feeding them. Be
sure
the fertilizer contains magnesium; iron; and sulfur.

OK, thanks for that, but given that I didn't do that this winter/spring,
can I give them a tonic right now, or will be it be a wasted effort?

Many thanks

Neil
