Organic Lawn Care Fertilizer Recipe
1 Part Bone Meal
1/2 Part Dolomite Lime
1/2 part Gypsum
(calcium and magnesium)
(calcium and sulphur)
1 Part Dolomite Lime
1 Part Rock Phosphate ~ or ~ 1/2 Part Bone Meal
1 Part Kelp Meal
Mixing and Applying Organic Lawn Fertilizer
Mix all ingredients together in a container that can be sealed, and one which is preferably air-tight. These ingredients can get a little dusty while being mixed - if this happens then it may be worthwhile to wear a face mask during mixing.
If more organic lawn fertilizer is mixed than is needed in a single application, then it will be important to keep the fertilizer as dry as possible in storage. An air-tight container in the shed is often the best idea for this.
Apply the dry fertilizer at approximate rates of 5 gallons per 1,000 square feet of lawn.
Once applied, the lawn is watered as normal, which should always be a healthy deep watering.
Application frequency will depend on the general health of your own lawn and soil.Once in Spring and once in the Fall for very healthy lawn and soils, or once at the beginning of each new season for less healthy lawns.
Notes on Alkaline Soils
If you live in an area where soils have higher Alkaline soils - then Lime should be cut down to 1/2 Part in the mixture. Be sure not to remove the Lime altogether though, it still contains Calcium and Magnesium, as well as being an offset for the slightly acidic seed meals.
If this organic lawn fertilizer is to be used every couple of months throughout the year on poor lawn soils, then Lime can be reduced further to around 1/4 of one Part.
If you don't know the alkalinity or acidity of your soil, then it's a good idea to do a either a pH test, or even better - a soil analysis.
