71 Apply 220 lbs Epsom salts (magnesium sulfate) per acre or a fertilizer containing magnesium. (When lime is not recommended and soil test magnesium is low)

73 Apply 2,200 lbs gypsum per acre. (When lime is not recommended and soil test calcium is less than 400 lbs calcium per acre)

300 As a precaution against fertilizer burn, water the plants immediately after the fertilizer is applied.

308 Uniformly spread fertilizer over area beginning 6 inches from the trunk and extending well beyond end of branch spread. Not necessary to remove the mulch before applying the
fertilizer. Brush or rinse the fertilizer from the leaves and stems. Always use an azalea/rhododendron fertilizer, such as that containing ammonium sulfate to help lower pH.
