Are they curling up or are they curling down? Any
discolouration?

Normally caused by stress--upward curl too much water and
downward curl by too little water. There are other possible
stressors. See

http://gardenline.usask.ca/pests/tomato.html if discoloured and
other possible causes.

Not sure this applies to tomatoes, but check the underside of the leaves for any tiny
insects.

Are they curling up or down, and are they curling from the tip toward
the stem, or from towards the middle?

They're curling upward. I don't notice any discoloration.

"Physiological leaf roll may be associated with environmental stresses
such as excess moisture, excess nitrogen, and transplant shock. Leaf
roll may also be related to moisture conservation during periods of
extreme heat and drought. Improper cultural practices such as severe
pruning and root damage during cultivation can also cause leaf roll
symptoms. Physiological leaf roll involves an initial upward cupping
of the leaves, followed by an inward roll. In severe cases, the leaves
roll up until the leaflets overlap. Symptomatic leaves become
thickened and leathery. Symptoms typically appear first in lower
leaves but may spread to the entire plant, depending on the severity
of the condition. Leaf roll is more commonly associated with staking
varieties of tomato, such as "Early Girl" and "Big Boy", rather than
bush types. In most cases, the condition is temporary and will have
little or no affect on plant growth or fruit production. "


Does this sound like your problem?

Yes it does, and I suspect it's over watering. I live in the Mojave desert
and when it gets hot, I'm prone to watering cause when I get hot and
thirsty, I think my plants are hot and thirsty also (grin). Thank you.

I have a grape tomato with yellowed leaves (at the top of the plant)
and it has rolled down leaves. The plant is about 2-feet tall and has 2
green tomatoes and several buds, that look healthy. Is this the viral
disease? Being that it is still late spring, should I keep it or buy an
extra-large plant from a nursery?

I also have an Early Girl and a Big Boy. Both have curling down leaves
but all are green. Neither have ever been dry nor over watered (IMO).
