Spring's no time for grub control
Green thumbs down
to all the ads for grub control in spring. It's just about the
least effective time to try to control grubs, insects then so close
to maturity that they're next to impossible to reach and kill. Baby grubs,
that's what we should go after. Babies are easy to kill, and
they have not yet done much damage, if any. Do that in August and
start with beneficial (predatory) nematodes before any of the broad
spectrum insecticides.
So why do all the lawn care companies push it? Same reason
jewelry companies run lots of ads around Christmas -- because we're
thinking about our lawn and willing to spend money.
Do make sure before you apply grub
control at any time, that grubs are actually your lawn's
problem. Dig some test patches and see how many grubs are
there. Far more lawns are dying of compacted soil, too little water
or fertilizer. Unnecessary insecticide is such a waste of money and
time to do nothing but start a bad ripple in your local
ecology.
