I used to use this years ago and it was very helpful. Since I have terrible soil that has to be amended for every plant, I thought this would be a good addition.

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?
Victoria on Apr 22, 2017
BEST ANSWER: This product may be used on a wide range of plants including vegetables, fruit, flowers, and herbs.
