How do you deadhead a small marigold plant....ie do you just pinch off the very end of the plant? I've tried this, but the plant is already dead and doesn't seem to help.
This article should tell you everything you need to know:

We just bought the plant last week. It was fine until two days ago when the leaves of the lower section started drooping. Today the one and only flower bud also drooped.
The new leaves and buds look like they have burnt and then slowly the whole branch dries up and becomes crispy.All the leaves and the bud have fallen off the plant. Does the plant still have a chance for survival?
I suspect transplant shock from root disturbance and drying out of the soil and roots. The soil surface in the pot appears dry.
Water it well and it may perk up and survive. Give it a week or two to show signs of improvement.
I have African Marigold saplings which are going on drying up after having attained a good height. 2-4 saplings keep turning brown and crumbling up.. please help
I suspect a water issue, too much or too little.
Does the planter have drainage holes or are the plants sitting in muddy wet soil and getting root rot?
If there is good drainage, then are you watering enough or are the plants suffering from water deficit/drought stress as a cause for the drying up of the foliage?
If the watering is as good as can be, what is the condition of the soil? Is it a fertile potting soil with good organic matter content that retains soil moisture, or sandy or course and porous.
I wish to plant marigold plants among my vegetable garden where I have planted seeds of parsnips and seeds of purple carrots along with plants of lettuce and tomatoes. Are marigolds compatible with these plants??
Yes! Marigold are excellent companion plants!

Are marigolds in the garden harmful to toads?
I recently planted some marigolds, (the small starter size) and within 2-3 days, something had eaten all the leaves. Whatever it is then started in on the petunia leaves - the other starter set that I had just planted. Any ideas what is eating these plants? We have a lot of snails in our yard and also rabbits in our area - though we have installed extra fencing to keep them out and I don't see any droppings. (We also checked the fencing and blocked a few possible entry points.) I have now put out snail bait but I'm hesitant to replant before I know what I'm battling! Any ideas?
That appears to to, either, bird or squirrel damage. I will include two articles that will help:

I live in North Carolina, and lately it has 95 degrees and over. Is the steaming sun the reason why my marigolds and perennials are dying?
They usually do well in high temperatures I do see what looks like clay soils and this will be the cause of slow growth here. They will grow much faster in a soil with more texture. Try adding organic material or a little compost before planting to help out.
