Tomato plants growing tips curling

[Dynamite]

Hi there, I have what I think may be a problem brewing but maybe not. Two of my Tomato plants which are Moneymaker in my Greenhouse seem to be curling at the growing tip. Please see photo below. I think it might be a problem and wondered if anyone had seen this before.

Kind Regards as always..........Rob

Curling leaves and tips of toms are no problem! They look healthy to me

That's good to hear then, I was getting worried. Thanks Scarlet.

They do this when they are growing very fast, often soon after being potted on when the compost s full of feed. Nothing to worry about.

Many thanks. Not concerned now.

Which is usually the time of year when there is a big difference between daytime and nightime temperatures another reason for curling leaves. Read under Biology, here

Tight curl on top leaves of tomato plants - what might be the cause?

Hi all

I've only looked into the matter briefly so far, and it would seem that there a quite a few things that can cause leaf curl in tomato plants...

I've got around 25 or so plants; 11 planted into a bed, and the other half in pots. All outdoors/none under cover. The top leaves of the ones in the bed have been curling inward. The potted ones seem fine. I wondered if the trained eye might be able to narrow down what the causes might be by looking at the photos below. I've taken some from afar and then some close ups of the tops leaves (at the bottom). I'm hoping an praying that it isn't the beginning of the end for my beloved toms!

Any help would be greatly appreciated. Happy to take more photos and answer any questions

Max, I've merged your thread with this one as its so similar.

[Russel Sprout]

Thanks veggiechicken. Might it be a little different that in my case it is the leaves at the tips that are curling rather then the tips themselves? Or does that amount to the same thing?

[veggiechicken]

The tips are leaves that haven't straightened out!

After the last bout mine started to grow properly again, until yesterday

It has been very hot during the day but only 9 or10 at night. They didn't like it so started curling again

Mine are curling too. They seem to do it when they are growing fast, and having got themselves comfy in their new self watering planter with some new compost, they are romping away. I've never had any issues from curly top leaves on tomatoes. If they start to wilt even when they have water that's another matter - it means they are too hot, and it affects the size and quality of the fruit on the top trusses.

What I am finding interesting is why the potted toms are not doing the same... The two main differences between potted and bedded that I can think of are:

- Water. I think I gave the ones in the beds more water a couple of days ago and was worried I had over done it. I find it a lot easier to judge watering amounts with potted plants. Could the leaves respond like that with too much water?

- Alpaca manure. The bed had some alpaca manure added. The pots didn't. I did read somewhere that the use of contaminated manure can cause leaf curl, and the photo on that page shows leaves which look very similar to mine.

I'm really hoping it's not that!
