deformed kale

Hello everyone, a few days ago I noticed one of my kale plants beginning to get deformed. Now I've noticed that several others are beginning to follow this same deformity. I'm concerned all of my kale plants will catch whatever this issue is. I don't use any fertilizer on my plants and I use grass clippings to mulch the garden bed. This is the first year I've grown kale and I know I planted them too close together I'm not sure if either of those things could relate to this issue. I'll post several pictures that will hopefully help. Thank you!

Those grass clippings -- any herbicides used on the grass such as a weed-and-feed formula?

Scotts turf builder, is there a name for what I've turned my plants into?

I'm not sure of what I'm seeing there. The plants look healthy, and if you are thinking the downward pointing leaves are a deformity, mine always do that when the leaves get big. The only oth thing I see is what looks like some of the secondary stems/leaves that form at the joint of leaf and main stalk look brown on the tips... In which case, no deformity, exactly but something more normal like too much/not enough water or too hot, or an early aphid infestation is drying out that new growth before it starts. But that's my best guess based on what I can see, which is not much.

If the Scotts turf builder you used had a weed killer in it, you may have herbicide damage to the kale. Never use grass clippings on anything if they have been sprayed with any kind of weed killer.

Yes it did.......so this is what's causing the deformity? It's odd there are fresh kale shoots growing out of one another.

If what I am seeing is correct, twisted deformed new growth, that looks like classic Weed-B-Gone damage. As I understand it the product contains some chemical / hormone that causes the plants to "grow themselves to death" and the new leaves are a twisted and contorted. Think of how the dandelions look in your yard after an application. I have used WBG in the past and found it has an incredible residual effect in soil, stunting and killing new transplants for sometimes an entire growing season. Great on your lawn, not so much in a vegetable garden. Doesn't surprise me that it would have a systemic effect and be carried by grass clippings from a treated lawn. Look at a bottle of WBG and see what the active ingredient is, and then compare it to a bag of what you applied to your lawn.

Not to preach or scold, but this is why I never apply broad spectrum anything. If you need fertilizer, apply fertilizer. If you have weeds, physically remove them or use spot treatments with herbicides at the minimum effective dose. What you apply in one area does not always stay only in that area.

The good news is that next year your soil should be fine, but the crop this year is probably a loss.
