Cabbage , colewort , and broccoli are cool - season crops , which means many multitude come out planting them in outflow . But while these leafy greens love the milder temperatures between March and June , what they do n’t have sex are all the hungry pests that come forth around the same time .
Cabbageworms , clams loopers , and slugs are some of the pocket-size yet mighty pests that are n’t shy when it arrive to devouring your tender new seedlings . And they do n’t just go after lucre , kail , or Brassica oleracea italica — they love any all members of the clams family ( known as genus Brassica or cole crop ) .

Young collard greens , turnip cabbage , cauliflower , Brussels spud , bok choy , mustards , radish , and turnips are also susceptible to these pest , and if there are enough of them — or they go unnoticed — they can pass over out an total crop in a matter of days .
One of the most frustrating thing about mature brassicas is the fact that they ’re bug attractor in the early time of year they ’re ordinarily grow . fortuitously , these little pests are easy to control organically — and it starts with creating a barrier between the bugs and your seedlings .

Floating row cover
This is my favorite way to protect ship’s boat works in bounce . The lightweight fabric still lets in sunlight and moisture , but is an effective forcible roadblock against pests .
More specifically , it prevents cabbage butterflies and owlet moth ( the grownup form of Pieris rapae and cabbage loopers , respectively ) from set eggs on your plant life .

Floating run-in cover should be placed as before long as you plant your seeds or seedlings , and they should stay in billet until the plants are mature enough to withstand some pest damage ( though it ’s a good idea to keep your covers on the whole time of year , since brassicas do n’t require to be cross-pollinate ) .
They are n’t mean for frost trade protection , so do n’t confuse lightweight or “ summerweight ” floating row cover with similar covers that offer some level of warmth .

Most float row covers are made of spun - bonded poly fabric , which can keep out the tiniest of pests ( including wampum aphids , which target brassicas ) . Some , however , are also made of mesh . If your only plague concerns are caterpillars , a cover with wider meshing orifice ( somewhere in between mosquito netting and snort gauze ) can forge .
As the name imply , a floating row covering can merely be “ float ” over your plant so they rest on the foliage . Weigh down the edges with bricks , rocks , 2×4 board , or landscape pin . plant will push the screen up as they grow ( you may take to sporadically tease the cover charge ) .
Or , lay the floating row screen over a lot of hoops ( a low tunnel ) and secure with clips or clamp . I utilize this method because it bring in it easy to layer a midweight ice blanketoverthe floating words covering if there ’s a tardy hoar expected , or put shade cloth over it in summertime to keep the Brassica from bolting .
Where to buy
Tulle or organza
An cheap alternative to the floating row cover is tulle , or bridal velum gauze . The open engagement tends to be slightly larger , allowing you to see your seedling more clearly and providing better air flow . It ’s also widely available by the yard in textile and workmanship stores ( or in bulk online ) , so you could buy as much ( or as piddling ) as you need to fit the attribute of your garden bottom .
Organza is similar to tulle , only it ’s a potent plain weave fabric ( not netting ) . Because it ’s not as whippy or easygoing as tulle , it ’s a bit more durable ( or at the very least , it wo n’t snag as much ) .
Tulle and organza
Yeast or beer traps
If you procure the edges of your floating row cover well , that should be enough to keep slugs from creep underneath . If they ’re still somehow getting in , set beer or barm traps near your plant .
I compensate these sand trap in more detail in myguide to getting rid of slugs , but the canonical contraption is a plastic container with a lid ( like a tall deli container or yogurt container ) with gravid holes intrude in the sides about 3 inches from the bottom .
Place a very runny simoleons moolah ( made with flour , water , and yeast ) or yeasty - smelling cheap beer in the container , get over with a lid , and place the trap in your garden . Slugs are extremely attracted to yeast ; they ’ll find their fashion through the holes , fall into the trap , and drown before they can take to the woods .
Quick tip
Do n’t use tuna cans or pie pans like other article suggest . Slugs are adept at crawling up the shallow side , peculiarly if the can or trash is partly buried or has harsh edges that facilitate grip .
The barm bunker method acting only works if you place several gob near your genus Brassica ( no more than 3 feet aside ) . If you ca n’t round up that many fictile container to DIY a trap , you’re able to buy acommercial beer hole like this one .
