Watering needs for different grass types

How long can you wait between waterings before the lawn starts to go brown? 12 - 21 days: Bahia grass, Buffalo gass, Bermuda grass, St. Augustine grass, Centipede grass 8 - 12 days: Carpet grass, Fine fescue, Kikuyu grass, Seashore paspalum, Tall fescue, Zoysia 5 - 7 days: Ryegrass, Kentucky bluegrass, BentgrassThe fine-leaved fescues (grass blades) as well as the "common" types of Kentucky bluegrasses, such as Park and Kenblue, require less water, fertilizer and cutting than turf-type perennial ryegrass or many of the newer "improved" types of Kentucky bluegrass.

Mowed the lawn again

Thought of having to cut a little shorter obsessed me and had to do it. Now the lawn looks like a carpet, but very colorful one due to my reckless fertilization; spreader wheel got stuck, couldn't keep up the straight line, etc. I lowered my mower for one unit - I call it a unit because 4in setting seems to cut a lot shorter than 4 inches - and now it does the magic. I installed the clipping guard so it leaves the clippings where they may fall. Hope it becomes a good nitrogen provider. According to the last post - which I posted 2 hours ago ;) - my lawn needs nitrogen and sulfur. Now, where the hell am I gonna get sulfur from? Besides, spreading lawn clippings after mow the lawn with the bag seems to be a good idea since it solves the agony I've been having for years: need for vacuuming out the stuff fell from my neighbor's dreadful trees and need for leaving clippings onto the turf. Just need more time, energy and a little bit of enthusiasm.
