(Cathy) Grubs. With the ban on pesticides, (with which I have no issues with) Hubby and I have noticed that most lawns this past summer took a beating. The lawns were eaten up and patchy with shallow roots. The lawn was very easy to pick up in pieces. Grubs! The grub population has soared with the ban on pesticides. As with any time there is a change to the ecosystem, good or bad, there is a consequence. As the saying goes, "time heals". If we just left well enough alone the ecosystem would balance itself out. Of course there are good years and bad, especially with the changing weather patterns. So, back to the grubs, what to do?
Web definitions:
(nematode) unsegmented worms with elongated rounded body pointed at both ends; mostly free-living but some are parasitic.
 In very plain speak, the nematodes attack the grubs, feed on them and use them thereby reducing their numbers. The idea is to spread them on your lawn in cool weather, so in the early spring or fall. They need to be kept well watered and with luck there should be a reduction in your grub population.

Off to the garden centre Hubby went and spent about thirty dollars for a pack of "live" nematodes. The package comes with a wet sponge that has been infused with one million nematodes. Nematodes are microscopic. The directions call for us to soak the sponge in a bucket of water to release the nematodes. That very "clear" water is then applied with a pump sprayer onto the lawn. I tried using a magnifying glass to see if any nematodes (according to package directions) were left behind in the sponge. I couldn't see a thing! 
Hubby and I were laughing that this entire affair was like the emperor's new clothes!

Hubby applied the nematodes to our lawn a few weeks ago and he says he has already noticed a decline in the number of grubs per square foot of lawn. Let's hope the lawn does better next year.

Now, what do we do with an infestation of nematodes?
