Late February-Early March -
apply a simple 15-5-10 for an early
green-up. Most companies that make
slow-release fertilizers also make
a non slow-release 15-5-10 that provides
for a quick two-week green up before
we get to the heart of the fertilizer
schedule. Some people will be tempted
to use a weed-and-feed at this time,
but if you've been following a planned
herbicide schedule, there should
never be a need. However, spot weed-and-feed
treatments are recommended for those
with turf-only landscapes or landscapes
that have been established for many
years. Warning: Most
weed-and-feeds contain Atrizine which
burns roots of young trees and shrubs.
Late March-Early April -
apply slow-release 3-1-2 ratio fertilizers.
Late June-Early July -
apply slow-release 3-1-2 ratio fertilizers.
October-November -
apply winterizer formulas for winter
hardiness. Ratios differ, but should
be specifically "winter" or "fall" formulas
designed for southern grasses.
(examples: 18-6-12, 8-12-16, 10-5-14) Will make lawns winter-hardy.
June-September -
if the lawn looks yellow use an application
of either granular or liquid iron.
Once a year should be enough.
