Fertilizing Azaleas with Cottonseed Meal: Schedule and Tips

Why Cottonseed Meal Works Well

Cottonseed meal is an excellent organic fertilizer for azaleas. As it decomposes, it acts as a mulch while slowly releasing nutrients, improving soil structure and acidity—both favored by azaleas.

Application Schedule

1. Early spring: Apply a ½-inch layer under the plants.
2. Mid-summer check: By July, see if the layer has decomposed. If gone, reapply another ½-inch layer.
3. Mulch each time: Cover with pine straw or wood chips to retain moisture and suppress weeds.

Long-Term Benefits

This routine builds rich, acidic soil over time, promoting healthier growth and more vibrant blooms. Avoid synthetic fertilizers that can disrupt the soil ecology azaleas prefer.
