Default Leaf curl?

The only plant that seems to have issues right now is my Principe Borghese.


It is setting fruit etc but the plant itself looks off...leaf curl? I keep checking the moisture levels in the soil before I water. Maybe I am overdoing the fertilizer? It has been hot lately and it was the first to wilt and it never really did go back to it's normal self after the heatwave.

Is this the nature of this variety or should I be worried?




Setting fruit fine

Not sure about the variety, but have you done an aphid check? Some of my plants that had more aphids than the rest exhibited symptoms similar to that.

Outline of the possibilities:

With your plant still setting fruit well, it sounds more like
physiological stress of some kind rather than one of the other
possible causes listed there.

I have one plant that has curly leaves like that, but it's Clint Eastwood's Rowdy Red. It seems to get worse at the slightest provocation, but always has some curled leaves, and the baby leaves are just... odd. None of the other 18 plants (all different varieties) have leaves that curl up.

I seem to be having the same problem with my German Red Strawberry; of the twenty-one plants in my garden, all surrounding the GRS look good. The GRS has leaf curl for no apparent reason. It is setting on fruit and has lots of blooms. It is this year's mystery.

Maybe it is just stressed. Nothing is dying...fruit is setting...blossoms are blossoming. lol I did give it a good Neem spray just in case so we shall see. I am trying not to sweat it but my tomato OCD kicks in and I keep stalking the plant for other signs of issues. lol

I had a few early in the season with rolled up leaves like that,
but they were more extreme than that picture. The curled
leaves had purple veins, and the plants stopped growing.
I guessed Curly Top virus or something similar (a viroid maybe),
which I have seen in previous years with similar early season
weather, and I pulled them. (Once the plants get it, they do not
recover.) The virii/viroids do not infect the soil, so I could replace
them with other plants in the same season if I noticed it early
enough.

(Kind of hard to miss when you have a row of 6 determinates
and semideterminates, all exactly the same height for the first
4-6 weeks, and then two weeks later 2 or 3 of them are a foot
shorter than the others, with curled up leaves with purple veins
on the top. Give them some foliar phosphate, wait another week,
and nothing happens, except that now they are more than a
foot shorter than the others. That is the disease.)

MY Smarty F1 in a pot does this all the time, so funny looking. But i have a ton of flowers which has stop growing, maybe some thing is going on here? No bugs yet, and this pot is beside other pots.

A twofer for uber and dice.

I completely ignore leaf curling unless and until other symptoms appear. And it's normal for many hybrids to always have curled leaves.

Leaves will curl if it's too hot, too cold, too dry, too wet or whatever. if the leaves curl over into a tube like structure then look for aphids.

If it's somewhat early in the season where any of you live, as it is with me right now, there's another condition called Leaf Roll that can occur and it's a physiological condition that occurs when foliage and root mass are out of balance and it self corrects as the plants mature.

If the leaves are curling and in addition start looking spindly with what's called a shoestring appearance then something to consider is CMV ( cucumber mosic virus) which also can infect tomatoes and CMV has a huge number of host plants such as weeds, etc.

Dice, would Curly Top really be a possibility in your part of the country? And while I haven't checked every possible virus around that can infect tomatoes, I don't wanna, LOL, the only viroid I know of off hand is the Potato Spindle Viroid, which also infects tomatoes and was the reason that Australia now prohibits importation of tomato seed unless accompanied by a phytosanitary certificate.

I do not know if Curly Top is common here. The plants simply
behaved like the descriptions and pictures of it. I suspected that
it might be something in the same family of plant virii as Curly
Top, a variant maybe, or a viroid (like the Potato Spindle Tuber
viroid that you mentioned).

The "stopped growing" part of the symptoms is always
suspicious, although that can be a phosphate deficiency
symptom, too, hence the foliar feed with a high phosphate
fertilizer. When I have let plants that looked like the ones that
I pulled go for the entire season, they rarely put on more than
a few inches of additional height once the symptoms appeared,
and the fruit that ripened were not up to their usual taste
standards for that cultivar.

I do know about physiological leaf roll, and that is something
that I usually ignore. When I saw that on Black Krim, for
example, it always started with the lower leaves and worked
its way part way up the plant. The disease that I described
in posts above starts on the top, on the newest leaves.
The plant will produce a couple of more sets of leaves before
it stops growing completely, and those all end up with the
leaf roll and purple veins symptoms.

I have generally just been ignoring it. I did spray everything down with Neem just in case. It doesn't seem any better or worse days later so I am not worried. Nothing is dying, fruit is still setting.
