    Curious if anyone has had success with early spring liquid Fert apps on warm season turf? How soon did you follow up with a granular srn? So,e irrigated and some not.

    Just curious as my rd 2 is a blanket app of my split pre app along with granular 1 lb N on Bermuda and 1/2 lb N on centipede.

    A full spray app might save me some money over a spray/spread app.

    How low a volume? When fertilizer is involved I consider 1 gallon low volume.

    When a soluble fertilizer is dissolved at a high rate in water(hot mix)--there results a high osmotic potential. It tends to pull water out of the grass plant. Result, burn. If temps are high--it happens fast--within hours.

    A bad mix under the right conditions will burn the grass right before your eyes. Not hours later. Have done it a few times only to never duplicate the mix or accompanying conditions.

    If you are thinking of doing liquid fert out of a PG type, don't do it.

    We are switching to a 100% liquid program. In the past our tankers have not had a large problem with burning. But yes, spraying or applying when its steamy hot is a poor choice. We spray at 3 gallons so its more high volume.

    We are in MN so cool season grasses.

    I should specify, first round is Pre-em and fert, 2nd is herbicide and fert mixed w/ X10. round 4 is herb and fert.

    Usually we arent applying fert when its super hot, just herbicide.
