Pest Control for Collard Greens
Collards are usually hardier than heading cabbages but the plants are susceptible to some of the same pest problems. The warm days of late September and early October can bring out flea beetles which can devastate young seedlings. If you see damage on your plants that resembles lots of tiny shotgun holes these tiny black beetles are probably the culprit.The damage is mostly dangerous for seedlings;older plants can usually survive the damage with no problems.
Over-watered plants can be subject to damage from slugs and snails. If you see large ragged holes in your plants during cool wet weather these mollusks are usually to blame.One tried and true method for controlling snails and slugs is to set small containers of beer around to trap them.
I like to use a margarine container (plastic tub) with an inch or two of beer to trap slugs. I recommend putting the lid back on and punching a few holes in the top to keep the beer away from pets and wild animals. The last thing you want is to wake up and find that raccoons or rodents have destroyed your garden in a drunken overnight raid.
My mom prefers not to use beer but a slug bait
that contains iron phosphate. These baits are effective and aren't harmful to birds and other wildlife. Hope this helps.
