Acid Mix 4-3-6 (1 lb Box)

1 lb Acid Mix for Containers and Small Plantings

Down To Earth Acid Mix 4-3-6 in the 1 lb box is sized for container blueberries, a few young berry plants, or a small group of acid-loving ornamentals. It is a convenient choice when you want to try the formulation without storing a larger package.

Why Choose the 1 lb Box?

• Easy-to-handle size for patios, balconies, raised beds, and small gardens.
• Suitable for blueberries, raspberries, azaleas, rhododendrons, hydrangeas, and evergreens.
• Granular fertilizer can be mixed into planting soil or applied around established plants.
• Provides a 4-3-6 analysis plus calcium, magnesium, sulfur, and humic acids.

Using This Size

Apply according to the current package label, work it lightly into the soil where appropriate, and water thoroughly. Soil conditions and plant size affect fertilizer needs, so test the soil when possible and avoid assuming that every acid-loving plant needs additional acidification.

Compare Acid Mix Sizes

If you are feeding several established plants or expect multiple seasonal applications, the 5 lb Acid Mix box may be the better value.
