Young tomato plant. Why are the leaves brown and crispy on the edges?

If you saturate constantly you need full sun all day long. They don’t need any shade.

It almost sounds like a fertilizer burn. Did you feed it anything? Is it in a pot or the garden? Do you have a dog who might have sprinkled it, my dogs can’t wait to pee in the garden when my back is turned!

I was going to say too much direct sun light and too little water . But i don’t think that’s the problem i will ask my gardening friend see what he says . post back later

Thanks all. The shade aspect is sort of non-negotiable. It’s the best spot I can manage for the time being. As summer progresses, it will move into more full sun.

It’s in a 4’ x 4’ square garden planter. I haven’t fed it anything but water and the soil mix. No dogs. Cats are a latent possibility, but I don’t think they’ve discovered their new litterbox yet.

We’re at 5,000 feet, so direct sun here is more than direct sun other places, but it’s in the shade by the mid to late afternoon.

I’ll wait to hear more. Thanks.

It could be early blight. I’ve had this problem many times. Your local garden center will have a fungicide that will help with this. The plant could also have an infestation of aphids.

Young tomato plants need a good soaking of about 2 quarts of water per day per plant. Make sure you have mulch to help retain moisture and keep the weeds out.

Can you take a picture of it? That would make it easier to identify the problem.

Check your nitrogen levels in the compost. Sounds like nutrient burn.

It’s called necrosis. Probably needs Nitrogen or Phosphorus
