Fertilome Soil Acidifier

If your acid-loving plants—like azaleas, gardenias, or rhododendrons—are showing yellowing leaves while the veins remain green, they are likely struggling with alkalinity or a nutrient deficiency. This product is designed to correct that specific imbalance and restore healthy, vibrant foliage.

You can use this on both potted plants and in-ground gardens. Just ensure you follow the mixing ratio of two tablespoons per gallon of water carefully, especially for containers where soil volume is limited.

No, this product is specifically formulated for acid-loving plants. Using it on plants that prefer neutral or alkaline soil could negatively impact their health, so it is best reserved for species like roses, fruit trees, and acid-loving shrubs.

Frequency depends on the severity of the deficiency and your soil's current pH level. It is best to start with a single application and monitor your plants for improvement before deciding if a second treatment is necessary.

This is a supplement, not a complete fertilizer. While it provides essential trace elements like iron, sulfur, and zinc, your plants will still need a balanced fertilizer to provide the primary nutrients—nitrogen, phosphorus, and potassium—required for overall growth.
