Last
week, I noticed that the bottom leaves of our tomato plants were curled
up. The leaves weren't yellowing, browning, or developing spots;
they were just bent in an odd curve that made the pale undersides
visible.
Even though I usually
try to be very proactive and look up problems as soon as I see
symptoms, this time I procrastinated. I've been living in fear of
the blight all growing season, and,
honestly, if my tomatoes were blighted, I didn't really want to know.
It turns out that I
could have set my mind at rest days ago. There is a leaf curl
disease caused by the Tomato Yellow Leaf Curl Virus, but the virus'
symptoms include yellowing leaf margins and crumpled leaves, neither of
which my plants show. Instead, chances are my curled leaves are
the result of letting the plants get a bit drought-stressed, then
saturating the soil a bit too much, all combined with my new, drastic
pruning regime.
The leaves may stay curled, but it sounds like I won't see any damage
to the plants' growth or fruiting.
I'm very relieved that
my tomatoes aren't going to die, but I would still like them to hurry
up and feed me! The plants are dripping with huge green fruits,
but none has even shown a tinge of color. As I read on more and
more blogs about homegrown tomatoes, my patience is wearing thin.
Fresh sliced tomatoes, vegetable soups, sweet pizza sauce --- I'm
aching to taste them again....
Thank you! You made me feel so much better. I had just loaded up another blog with a big old bowl of ripe tomatoes sitting at the top of their post. Grrr.... (You can keep those zukes. Our summer squash are doing astonishingly well this year, and I'm actually starting to think we may overload our freezer.)
Here's hoping we both have tomatoes before too long.
Hi Anna:
Our greenhouse tomatoes get curled leaves during the heat of the day and who can blame them? It gets to over 110 in there! Right now though in the cool of the morning they're just fine.
I do notice it happens with some varieties and not others. Those with thinner, longer leaves like my Striped Romas always get hit but those with a bigger canopy and larger leaves like the Brandywines and the San Marzanos don't experience it so much (and they're near enough to the curled leaved ones so it's not the environment).
Hope that helps!
The heat is an excellent point. We've never had sustained hot weather like this in my memory! (Of course, we're only talking highs in the low 90s...
And you're also right that some varieties seem much more prone to the curling than others. I'll have to see whether the non-curl varieties do better in the long run --- so far, they all seem happy.
