If soil test Mg level is low and lime is recommended, use dolomitic limestone.

Coastal PlainLow: 0 - 30 lbs/acre Medium: 31 - 60 lbs/acre High: >60 lbs/acre

Comments:

077.

Apply 6 pounds of 16-4-8 per 1000 square feet at the time of seeding and repeat in early spring. If more growth or color is desired, apply 3 pounds of 34-0-0 or 2 pounds of 46-0-0 per 1000 square feet as needed.

078.

Apply 10 pounds of 10-10-10 per 1000 square feet at the time of overseeding. Apply 3 pounds of 34-0-0 or 2 pounds of 46-0-0 per 1000 square feet in early spring and repeat as needed to obtain the desired growth and color.

079.

Apply 3 pounds of 34-0-0 or 2 pounds of 46-0-0 per 1000 square feet two weeks after overseeding. Repeat the application in early spring and as needed to obtain the desired growth and color.

Fact Sheet:

Clippings do not contribute to thatch under proper management and thus, do not need to be removed. If they are removed, increase the fertilizer application rate by 30%.

CAUTION: Water lawn thoroughly immediately after applying fertilizer. Do not apply fertilizer when grass is wet.
