Frequently Asked Questions

What plants is Acid Special formulated for?

It's specifically formulated for acid-loving plants, ideal for use in the nursery and landscape. It's described as a favorite for azaleas and rhododendrons specifically.

How fast does it correct high pH conditions?

It provides a rapid correction of high pH conditions, rather than a slow gradual shift. That speed matters when acid-loving plants are already showing stress from alkaline media.

What growth and flowering effects does this formula support?

It promotes lush vegetation and better blooms in acid-loving plants once pH conditions are corrected into their preferred range. Both foliage density and flowering performance respond to that pH correction.

Why is the acidity rating so much higher than other Peters Professional formulas?

This formulation carries an acidic rating of 1518 lbs. CCE with a urea content of 50.5, substantially higher than the general-purpose Peat-Lite formulas in this line. That strength is what allows it to rapidly correct high pH conditions rather than just maintain an already-acidic media.

What size and packaging is this listing?

It ships as a 25lb bag, matching its high acidic rating of 1518 lbs. CCE. That volume suits commercial nursery and landscape feeding programs for azaleas and rhododendrons.
