how to organically stop white butterfly grub eating my cabbage?

Answer 1

Cabbage Whites are only one of the species of butterflies that will lay eggs on brassicas. Manual control includes examining the leaves of the plants regularly, every one to three days, for clusters of the eggs, usually, though not always, on the undersides of the outer leaves. These clusters can be 'rubbed off' with the fingers.
You can perhaps enjoy the pleasure of picking off the caterpillars (which must be destroyed) but if they are at that stage, you will not be able to get to many of the grubs which have infested the heart of the plant without ruining the plant in the process.
Fine mesh netting will prevent the butterflies reaching the plants, though this must be frequently checked that it is not affecting the growth pattern of the plants.
Another effective treatment is Derris Dust, in itself a natural product, which kills the caterpillars and many other pests.
Some other advice you may find useful is on the Web of course. Try the source below for a start - it's a membership site but has useful pages of information for non-members too.

The most natural and healthy diet for humans is an omnivorous diet, and not a plant based diet, or a meat-based diet per se. The Paleo Diet can be very widely varied and omnivorous for the most part, but the most important thing is that it’s unprocessed, and avoids the worst foods that agriculture brought mankind… refined inflammatory vegetable oils, refined grains (some are worse than others), and sugar!

As you can see, the benefits of adopting a Paleo way of eating can be incredible! I’ve been eating 95% Paleo for the last 5-6 years and I’ve never felt better. I have dozens of friends that have adopted a more Paleo way of eating too, and have seen all sorts of health problems disappear, including eliminating acne and other skin problems, digestion problems, improving brain clarity, and of course, losing a lot of body fat!

Basil and rosemary grown nearby will discourage egg laying. Hand pick for now, then toss worms into a cup of soapy (dish soap) water & flush or toss into the trash. Spray a solution of water with cayenne pepper on cabbages to deter more worms from eating, or dust soil around cabbages with cayenne.
Carrots grown near cabage also act as a deterrent. See this site for more info on Companion Planting:

Answer 4

I've got no idea how to stop butterfly grubs eating your cabbages, but I do know how to organically stop carrot fly grubs eating your carrots.

Answer 5

I think the easiest, most effective method is to use a row cover. This is a white fabric that you lay across your plants. It allows sun and moisture to get in, but not the bugs. This works great for cabbages, green beans, brussels sprouts, broccoli, etc. See the source link for further description.

Answer 6

I ended up using Caterpillar dust, they ate up all my cabbage, cauliflower leaves, and broccoli leaves. The white moths lay eggs in the crevices, and the caterpillars that hatch do the eating. My friend said he used a concoction of thin vegetable oil, mustard seed, and cayenne sprayed on the leaves to thwart the bunnies and deer, and it seemed to repel the moths as well, so I'm going to try that this season.

Answer 7

Plant the plant Feverfue in amongst the cabbages as this deters the cabbage moth and so do not get near enough to lay their eggs on the cabbages.

Answer 8

Neem Tree Oil is the way to go. It sprays on and works great for pests and fungi problems. It's from a tree native to India, and can be found in a good gardening center.

Answer 9

Bury a peeled garlic clove next to the plant (with the pointy end just peeking out) . You wont have any insect problems.

Answer 10

The only hope you have is to cover your plants with netting before the butterfly lays its eggs.
