Down to Earth Acid Mix 4-3-6 | 50lb - For Acid Soil Loving Plants

50lb Acid Mix Fertilizer for Acid-Loving Plants, NPK 4-3-6

Rhododendrons, azaleas, and blueberries decline in soil that drifts toward neutral or alkaline pH, and a general-purpose fertilizer doesn't correct for that. Down to Earth Acid Mix is blended specifically for acid soil loving plants, built from cottonseed meal, langbeinite, fish bone meal, rock phosphate, humates, and kelp meal.

Sold as a 50lb bag, NPK 4-3-6.

Frequently Asked Questions

What plants is Acid Mix formulated for?

It's blended specifically for acid soil loving plants like rhododendrons, azaleas, hydrangeas, evergreen trees and shrubs, blueberries, raspberries, and other plants that thrive in low pH soil. A general-purpose fertilizer doesn't target that same soil chemistry.

When should I apply this fertilizer?

Apply the acid mix in early Spring for vegetative growth and again when blooms appear, to encourage lush flowers and fruit. Fall applications promote healthy root growth and boost resistance to extreme winter temperatures.

What ingredients make up this blend?

The ingredients are cottonseed meal, langbeinite, fish bone meal, rock phosphate, humates, and kelp meal. That combination is what gives the mix its acid-forward NPK 4-3-6 profile.

What size is this listing?

This listing is a 50lb bag. It's designed for acid soil loving plants specifically, rather than as an all-purpose fertilizer.
