    Soil test shows I need phos and I now it will also help out with drought and root growth. What is a good and inexpensive phos source? In granular form of course.

    Thanks

    0/46/0, triple super phosphate, if you need a little nitrogen, diammoniaphosphate, 18/46/0. leave off the high K during the summer unless you really need it. Both fertilizers mentioned are about 8 bucks a bag at your local farm supply and you will need a lot less than you would if you use the regular starter fertilizer
     
  5. why leave off the high k in summer?

    proably because most High K ferts are MOP -- and can have a very high salt index. Unfortunatelya decesion made on economics rather than plant health.
     
  7. I keep forgetting the lawn care industry uses the cheap mop. Too bad, because k helps with stress, if you use a source with a low salt index!
