1. Feed that lawn! "Right now, it's key to work on your lawn," says Jim
Welshans, regional turfgrass educator at Penn State University. In fact,
despite what many people might think, autumn, not spring, is perhaps the
most vital time in many parts of the country. Welshans explains: "In
Pennsylvania we grow cool-season grasses, and during the summer they're not
very active." Come autumn, however, they revive.
Lawns with these cool-weather grasses — Kentucky bluegrass, fescues,
perennial ryegrass — should be fertilized in two waves, say Welshans and
others. The first application, from mid to late September in places like
Pennsylvania, should be a fertilizer that's high in nitrogen. The second
application, roughly about Thanksgiving but before the ground is frozen,
should be a fertilizer that's high in phosphorus, which will prepare that
plant for next year, says Welshans. (Exact timing for all the advice in this
story will vary depending on where you live. A good way to determine if you
're giving your lawn what it needs is to get a soil test. It will give you
information like soil pH and nutrient levels, and provide recommendations
for fertilizer amounts.)
Bob Mugaas, a regional extension educator in horticulture who's affiliated
with the University of Minnesota, recommends modest application of nitrogen
during the first couple of weeks in September, and a repeat application
around Halloween in the Twin Cities area. If you missed the first window,
don't fret, says Mugaas, but simply make the second application around
Halloween. Why not squeeze in two doses in quick succession? "You don't want
to stimulate the tender, succulent growth" as the grass girds for winter,
he explains; the late-season application is more for the root system.
Another tip: Homeowners can drive over leaves with a lawn mower to create a
fine mulch as long as the results don't blanket the lawn.
What's your home worth?
But … Exceptions to the "fertilize!" rule are the desert Southwest and the
Deep South — places like Georgia, Alabama and south Texas — where lawns
generally have Bermuda, Zoysia, St. Augustine and centipede grasses. These
largely go dormant in winter and don't need fertilizer, says Dave Han,
associate professor at Auburn University and state extension specialist for
turfgrass. "I cut off fertilizing in this part of the world about Oct. 1,"
Han says. Fertilizing can be extended along the warmer Gulf Coast, however,
and you can feed grass year-round in south Florida and coastal Texas, he
adds.

Put down a winter fertilizer high in N (nitrogen) about 3 weeks after your
average first frost date. The rate is about 1 lb N per 1000 sq ft (so if it
is 32-0-10, it is about 3 lbs fertilizer, and if it is 46-0-0, it is about
2 lbs fertilizer). If that date + 1 week has already passed for you, don't
do anything or it is just a waste of money.
I no longer buy the idea of adding fertilizers high in P (phosphorous) for
winter for cool season grasses, unless you know your soil is lacking P from
some kind of test, in which case you should apply P throughout the year,
instead of just before winter.
Note the above is only applicable to cool season grasses. | i***e

昨天放完入冬肥料后后悔了。
树叶还在掉，明天还得用割草机收树叶:( | a****j
