Can I spread Hi-Yield Super Phosphate with scott's broadcast edgeguard deluxe spreader?

soil analysis says need high phosphorous on lawn. need to spread around 1.5 lbs./1000 sq ft

No. This product is made to be used directly in the planting trench for bulbs and small plants and a spreader would likely just fling the granules around. We recommend that contact VPG directly and with your soil analysis they should be able to tell you which product will work best for your needs. You can reach them by calling 888-583-5296.

Can I also use Hi-Yield Super Phosphate 0-18-0 safely on peony bulbs where I already used fish fertilizer?

Also, could this also be used on blue geranium newly planted roots or Pink Muhley grass that has just been planted (it's sprouted about 8 inches.) Thank you


We would recommend contacinting your local cooperative extension office for specific on fertilizing and treatment timing intervals. A soil analysis on what your soil is needing would help determine if this would be the proper time to use Hi-Yield Super Phosphate 0-18-0
