Organic Lawn Care Calendar

All Grasses Winter - January to April

Adjust pH. The soil pH should be adjusted during the lawns dormant time. Soil amendments such as Aerify and Nature's Magic tend to buffer pH so adjustment should be performed first. For best overall results, adjust to your lawn turfs ideal pH.

Grass pH Ranges	pH Low	pH High	Ideal
BAHIAGRASS ARGENTINE, PENSACOLA, TIFTON	6.0	7.5	6.7 – 6.8
BENTGRASS COLONIAL & CREEPING	5.6	7.0	6.3
BERMUDA HYBRIDS & COMMON	5.6	7.0	6.3
BLUEGRASS	5.7	7.4	6.5 – 6.6
BUFFALO	5.6	7.0	6.3
CARPETGRASS	4.5	5.5	5.3
CENTIPEDE	4.3	5.8	5.0 – 5.1
FESCUE RED & CREEPING	5.6	6.8	6.2
FESCUE TALL	5.6	7.0	6.3
ST. AUGUSTINE	6.3	7.8	7.0 – 7.1
ZOYSIA	5.5	7.0	6.2 – 6.3

Note: Most broadleaf weeds like soil pH above 7.0. With the exception of St. Augustine grass, ideal pH is a deterrent to broadleaf weeds such as crabgrass.

Once you get the pH under control, you can start building your soil quality.

Aerate your lawn so air, water, nutrients and biolife are able to penetrate to below the root line.
Supply the soil with all the micronutrients, plant hormones, vitamins, micro-organisms and organic material needed.
Apply pre-emergent weed control agent.

Note: Centipede grass is a low fertility turf. More than 16 pounds Nitrogen a year is too much. Phosphorous harms its root system and it does not handle Potassium well. Any fertilizer with a N-P-K rating of 8-0-0 is harmful to the turf.
