The second instance where you might be dealing with both warm season grasses and cool season grasses on one property would be in the instance of mixed lawns. So meaning, you’ve got both a warm season grass like Kikuyu fighting along with Tall Fescue in the same lawn.

And you really can’t get it to be one type of turf. So you just face the facts that you’ve got both. This would be very common in a lot of Coastal Southern California, even getting further north.

So what’s the answer?

Because again, you’ve essentially got cool season turf growing in there that is very strong in the spring and fall mixed in there with warm season grasses that by the time they’re coming to fall and winter, they are looking dormant. So you get these patches of off color turf.

So the best way to really manage that fertilization program is somewhat even it out. So even though we say true cool season is mainly spring and fall. That might stretch to an application that’s more late spring/early summer. Another one late summer/fall.

You’re really just evening that program out a little bit. Making it less dramatic on either end of it.
