Marigolds Reddish & Stunted - Knowledgebase Question

I grew your white marigolds from seed this spring. My main plot has only grown about 12", and a majority of the leaves have turned rose colored, and one plant is now dying back. The extra marigolds from this same planting I just stuck in my vegetable garden because I hate to throw out seedlings. They both get about the same amount of sun and water. The ones in my vegetable garden are taller and the foliage is great. Any suggestions? I have used Miracle Gro on both areas periodically but no other fertilizer.

Based on the symptoms you have described I would guess there is a soil problem, probably stemming back to the pH being too acid. This would make the needed nutrients unavailable thus causing the plants to turn purple and stunt. However, the only way to find out for sure is to run some basic soil tests and see. Your County Extension (228-1556) should be able to help you with the tests and interpreting the results.
