I noticed yesterday that some of my tomato plants have something unusual
going on . The lower leaves on a couple of my plants have turned a darker
green and started curling up toward the top side . They feel strange to the
touch too , kinda "leathery" for lack of a better word .
Anybody got any ideas what I might have going on here ? Plants are in
"virgin" soil , used to be oak forest . Ground was broken for the first time
this spring , plants were put in holes with a 50/50 mix of dirt and
manure/compost , a tbsp of epsom salts in the bottom of each hole . 3 weeks
after planting <about 3 wks ago now> I applied a light feeding of 13/13/13 .
THis problem has just shown up in the last few days and I'd like to nip it
asap . They've all but one got tomatoes on them .
every thing i'm seeing says that this is caused
by the plant top growing faster than the roots
(many reasons) and that the plant should grow out
has there been uneven weather lately (too much
rain, not enough sun, or vice versa) or are you
watering regularly if it is too hot and dry?
We've had some really hot/dry weather , and I've been watering when the
soil is dry abt 1/4" deep . Cook - I checked out your link , nothing there
that resembles what I'm seeing , but lotsa good info <bookmarked> thanks !
Tomorrow or wednesday I need to run into town on some other business , I
think I'll run a sample leaf past the county extension office - along with a
soil sample for testing . Could very well be a ph problem as Pavel314
Found my answer at Texas A&M's extension website ! Thanks , I seldom use
long search strings because the results are often weird but this time I
found exactly what the problem is . Conditions fit too , it was pretty wet
for a while and now we've gotten into 95 degree days with intense sun all
15. Q. What causes tomato leaves to curl?
A. The exact cause of tomato leaf roll is not fully known. Tomato leaf roll
appears about the time of fruit setting. The leaflets of the older leaves on
the lower half of the tomato plant roll upward. This gives the leaflets a
cupped appearance with sometimes even the margins touching or overlapping.
The overall growth of the plant does not seem to be greatly affected and
yields are normal. This condition appears to be most common on staked and
pruned plants. It occurs when excessive rainfall or overwatering keeps the
soil too wet for too long. It is also related to intensive sunlight which
causes carbohydrates to accumulate in the leaves. Some varieties of tomatoes
are characteristically curled

Thanks for that information. I have a couple of plants that looked
like they were about dead but have perked up since we have had a few
days of no rain. We have had 6.8" of rain this month and I believe it
was close to that last month. Add that to a very cold spring that
kept me from setting out tomatoes I think I will be lucky if I get
decent crop. Oh well, there are lots of canned tomatoes in the
Most likely tomato leaf roll, caused by a specific gene ('wilty' gene) in
response to stress (anything from heavy fruit load to high heat or excessive
Virus that cause leaf roll usually also cause the leaves to become lighter,
rather than darker green.
Herbicide damage is most likely to affect new growth and cause more
