Tomato leaf query - 2 different plants/problems
in Fruit & veg
Hi there,
I've had a decent success getting some tomato plants growing well. However in the last few weeks I've noticed a few leaf issues creeping in on two plants in particular. I've tried googling but no photos seem to match what I'm seeing.
The Chocolate Cherry is only showing the browning/curling on newer mature leaves right at the top of the plant which is what has confused me there. I've cut those leaves off just in case. It's planted into the soil which had an inch of compost added at transplant stage, a straw mulch, and feeding roughly every 10 days.




And the other variety I have issues with right now are Koralik, planted in containers. These have lots of brown marks and yellowing on the affected leaves. From Googling it seems it could be over feeding? It was fully fresh compost they were transplanted into, and feeding the recommended amount of tomato feed every 7-10 days. Could it be too much, or is it some disease?
This is one leaves throughout the plant not just lower. New growth seems okay.

Wasn't the compost because all the others where grown in the same.
If it’s just a few leaves I’d just cut them off. Difficult to see how much it is.
Looking at the top growth, some do do that, they straighten out as they grow on.
you can cut the lower leaves off up to the first truss.
The curling leaves can often be due to low temps.
You obviously have fruit on the Koralik so feeding regime is OK. If no fruit forming on the Choc Cherry, leave off with the feed until fruit begins to form.
Some of the marking could be water reacting to sunlight ( if you have had any ? )
Leaves will naturally deteriorate - they grow old like the rest of us and don't particularly help the plant so can be removed but that is usually the lower leaves. Be careful nipping off the top leaves that you don't accidentally remove the growing tip.
If in a GH, ventillation ?
Difficult to offer much helpful advice without a bit more info
Thanks Lyn. I think my concern is if it's bacterial/viral and possibly likely to transfer to those plants around them at all. The Koralik seems to match watering/feeding symptoms more so I'm just trying to keep an eye on that to see if it helps ha. I grew those last year with no problems but we'll see!
The Chocolate Cherry - it was the browning/scorching appearance on the leaves and the black dots that had me worried more than the Koralik. I've cut those leaves off but wondered if they look like any particulary disease or cause for concern?
Roughly, where are you?

South Yorkshire. Grown indoors until 6 inches tall, then into the greenhouse, then hardened off outdoors before planting at the very end of May, I think around 25th or so. They've been potted on regularly throughout that process too.
Apart from a few cold nights start of June we've been okay and had a very nice growth spu Each time it's been lower than 10 overnight I've fleeced them all just to be sure.
Chocolate Cherry are in the ground directly, spaced 2 feet apart from others, staked. Soil is a clay type which I've dug out and mixed some gravel into to improve drainage a little more. It's around 3 feet tall now. I'd never heard of the brown spots on newer growth before that's all! Thankfully the growing tip is still in place. I learned from that mistake last year, ha!
Koralik - there are two in a large long container, spaced 2 feet apart between planting at the base. Full compost with some gravel at the very bottom to stop compost falling through the drainage holes.
I have a few tomatoes growing in the greenhouse also but they're all fine in there so that's something!
This summer hasn't been much of a summer so far with the exception of a few baking hot days and I think your plants are sulking.
Only chop off leaves that are badly damaged.
The curling at the top of the plant is also down the weather.
Keep the compost only slightly moist until summer arrives and your plants will be fine
PS - the curling will sort itself out - no need to remove anything

Pete has reinforced what I said about the top leaves, Give them a bit longer, the weather seems to be changing, it’s very cold here today, last week was too hot to work out in it.
plants don’t know where they are.
