Lost Fertilizer Labels? How to Safely Use Unknown Miracle-Gro Mixes on Vegetables and Blueberries

Gardener uses regular Miracle-Gro for vegetables, acidic blend for blueberries. Labels lost in shed heat. Asks for a quick test to tell which is which (e.g., copper penny reaction).

No Easy Test Exists

But don't worry—as long as neither is "weed & feed" with herbicide.

Practical Approach

• Alternate between the products.
• Check soil pH monthly; add lime if it drops.
• Occasional azalea food on vegetables won't hurt.
• Water-soluble fertilizers are quick-release; apply often but lightly.
• Could mix all together and spray everything—likely fine if not overfed.
