You should be thankful that you got rain 16 hours after fertilizing ! No
problem with that, unless you got a huge downpour of 5-10 inches overnight
which "can" leach the nutrients out of the soil. One of two inches of rain
is a blessing just after fertilizing.

Just because you don't see a change after 9 days is not a worry either. Give
it at least several more weeks.

Aeration should not be a problem either.

You DO need to :


1. Be more patient

2. Not worry quite as much



hope this helps !!
