15-30-15  this is 5x more nitrogen than the plant needs.  Aphids love this..
You will have a big reduction in aphids just by fertilizing with a N = 3 or

If you switch from hi to low,  it may take 6 to 8 weeks for the current high
to leach out.


Despite all our accomplishments, humanity owes its existence to a six
inch layer of topsoil and the fact that it rains.
