Reviving a Magnificent Magnolia: Fertilization Strategy for a Declining Giant

A 40-foot magnolia in Little Rock, Arkansas, planted in the 1960s on a steep hill, suddenly appears nearly bare with minimal spring blooms and dropping new growth. The owner seeks to save this beloved tree.

Diagnosis and Treatment

The expert recommends fertilizing with 10-10-10 fertilizer at 1 pound per inch of trunk diameter, scattered around the tree and watered in thoroughly. Ideal timing is just before rainfall to avoid manual watering. Repeat in early spring.

Follow-Up: Evaluating a Specialty Fertilizer

The owner found a "TreeHelp Magnolia Fertilizer" online. The expert notes it's likely 13-13-13 (similar to 10-10-10 but more concentrated) with minor elements. However, standard 10-10-10 or 13-13-13 from a local nursery costs significantly less ($22-26 for 40 lbs) and works equally well. The key is consistent fertilization to replenish soil nutrients.

For a tree this size and age on a slope, proper fertilization combined with adequate moisture should restore vigor and bloom production.
