The leaves on some of my tomatoes are developing a "woody" appearance.

off.

I looked at leaf symptoms he

but didn't see anything that looked ike it.

A picture of the leaf and the plant might be useful.

I'll see if I can get something up today.

Are the leaves at the bottom dieing, or the leaves at the top?

Pretty much uniform distribution.


Are these tomato plants you started yourself, or tomatoes you bought
from a store?

I got them at Lowe's (building supplies, not grocery store). The last
time I was there, plants on their shelves had the same markings.
