About Cottonseed Meal

Cottonseed meal is a byproduct of the cotton industry.  In the cotton making process, each boll has to be removed of its seeds; the leftover cottonseed is pressed for cottonseed oil which is used as a cheap cooking oil.  The meal left over from oil production is dried and used as animal food or fertilizer.

Cottonseed Meal Fertilizer Analysis

Cottonseed meal is an excellent fertilizer, especially as a nitrogen source for acid-loving, fertilizer sensitive plants such as rhododendrons and kalmias.  Cottonseed meal has a 6-2-1 NPK ratio (Nitrogen-Phosphorus-Potassium), making it a great main-season nitrogen source.  Because cottonseed meal is an organic fertilizer, the nitrogen is slowly released over the season as the meal is broken down by soil microbes.  As a plant-based product, cottonseed meal has a host of necessary micronutrients.  Cottonseed meal also tends to be a soil acidifier, as it is mostly organic matter - This greatly enriches the soil and helps beneficial soil fungi flourish.

How to use Cottonseed Meal

Cottonseed meal is an easy-to-spread, dry granular fertilizer.  While it is almost impossible to burn plants with cottonseed meal, it is still best to follow recommended rates of application.

Typical application:

  • Newly Planted Trees - 0.15 lbs over a 3-foot diameter circle
  • Newly Planted Shrubs - 0.05 lbs over a 2-foot diameter circle
  • Garden Areas / Beds - 16 lbs over 1000 square feet (50 x 20 rectangle)

For rhododendrons, azaleas and other acid-loving shrubs, cut the application rate in half.  These doses are best applied in two applications, one in early spring just before leaf-out, and another in early summer but no later than July 1st.
