Brack’s Potting Mix
If you’re using a 5 gallon bucket to measure out these ingredients:
1 part Peatmoss 1 part Perlite
2 parts Pine Bark mulch or mini-nuggets
then add:
1 pint (about 1/4 of 1 lb. coffee can) Dolomitic Limestone
1 pint Gypsum
2 pints Super Phosphate
Mix ingredients thoroughly while singing the Rhododendron Song........just kidding- you can hum it instead!
