Is this good for lawns?
Paul C on Apr 25, 2017
BEST ANSWER: I do not use a high phosphate fertilizer on my lawn. It is a hazard to water runoff and a potential pollutant. Phosphate promotes algal blooms in surface water. I use triple super phosphate for flowering bulbs and root crops like onion and shallots. I feed my lawn with a high nitrogen low phosphorus content fertilizer.
Is this for roses?
