The leaves on some of my marigolds are turning red. Am I overwatering?

Answer 1

FERTILIZER...GO WITH THE OSMICOTE GUY.
Except osmicote is a SLOW release feed.
His Idea is correct, but you need a faster cure. So get the Osmicote for the long term. And get a liquid feed for fast pick up and green up. Neptune's Harvest is my favorite, but I won't turn down Miracle Grow either!
You can use Osmicote, and the liquid feed together!!!
You can google osmicote or oZmicote I don't know.the spelling off hand...
but you will see for your self you can use both, when used AS DIRECTED TOGETHER!

Answer 2

It depends. Are all the leaves turning red or just some?

Leaves turning red is usually not a symptom of overwatering.

If only a few of the oldest leaves are turning red, this is not a problem. Plants will recycle the chlorophyll in their leaves and use it in the new leaves as older leaves become less efficient.

If there are a lot of them turning, but mostly the old ones, you may need to add a little fertilizer that has a relatively high first number (nitrogen).

There is a small possibility is could be sun scorch, but it doesn't sound like it. It could possibly be some other things, but more information would be needed.

Answer 3

no you have a nutrient deficiency, don't quote me but i think red indicates phosphorous deficiency. go to a garden center and but some slow release fertilizer called osmocote. I use it and it works great. a lot of your nurseries use it also. just follow the instructions on how much to apply. Hope this helps.

Answer 4

are they planted where they just get the hot sun and no shade? it sounds like the leaves are getting burnt.they can take the sun,but they should have some shade.
