Pepper and tomato leaves turning white

Asked May 14, 2017, 10:40 AM EDT

I may have over fertilized (aged chicken manure + bone meal) a potted tomato (see photo) + added too many of these amendments to the soil before installing seedlings to the garden. Is this why the plant leaves are turning white in varying degrees? Also...I'm attaching a photo of mushrooms that are growing out of a stump in my yard. What kind is this? Is it edible? Thanks!

Thank you for the question. You should consider all mushrooms poisonous unless you can get a positive identification from someone experienced in local mushroom identification. The study of mushrooms and their identity is quite specialized and there are many species of mushrooms that look very similar to one another, so you should contact a specialist. Here's a link to the Minnesota Mycological Society: http://minnesotamycologicalsociety.org/ In the meantime, do not eat the mushrooms.

The tomato plant leaves look like they suffer from sunscald. This happens when the new plants are exposed to too much direct sunlight too soon. They need to be hardened off. This is the process where the plants are gradually exposed to more and more outdoor weather, including sunlight, and allowed to become gradually accustomed to wind, sun, and temperature variation.

Your plant will probably recover, just expose it to the weather more gradually.

Thank you for contacting Extension.
