I laid new sod last Nov (7 pallets of St Augustine Palmetto in the backyard and 3 pallets of Zoysia Palisades in the front) and then we got hit with a freakish snow storm in February here in Texas (zone 8b). I lost a bunch of landscaping (shrubs, etc) but it looks like the sod is in better shape than I expected. I have done nothing since the sod was laid except keep water on it. Can I get some guidance from the smart folks here on fertilizer and any other treatments I should put on the yard?
