Tomato Growing 2024

I'd suggest that maybe they are not getting enough sun, it's not been a very sunny spring and there does appear to be a lot of foliage outside which might restrict light to some extent.
I assume the roof is allowing light to come through?
Have they got their first truss yet, not easy to see from the pictures.

 

I'd agree that the outer planting probably gives enough shade at this time of year @pete
Earlier in the year, on an averagely sunny day, that might be different. I know my back windowsills can get hideously hot, and smaller plants can really suffer, so I pull the blinds down until the sun moves round. The constant juggling!
It's quite difficult to judge without being there in person though.

 

My plants are generally growing well, they are in self watering growpots as usual. This set up does mean each pair of plants are quite close. This does not normally pose a problem but yesterday evening I discovered that the lower leaves of two plants were going yellow and were infested with aphids (green fly). I cut away the affected leaves and sprayed with soft soap. Never had to do this before.

 

I've not found the need to shade anything this year, I do have a fair amount of growth around the greenhouse these days to be fair, but I find mostly good ventilation is better than shading for most plants.

But would agree that under glass midday until 4pm on brilliant sunny days you can get leaf burn, especially if the plants are not used to it.

 

Haven’t shaded anything here yet either, @pete , however if the forecast for the next week is right I might finally be pulling down the blinds

 

Hi all, again...

Anyone has any ideas why would top leaves curled up like mine?

 

I'd say its alright, its not a problem.

 

Mine do the same in the greenhouse every year when we get some heat.
They'll look normal in a few days - I think it's the sudden burst of heat that has got them growing quickly

 

Okay, I'll see how it goes. These have been like that since Friday.

 

It's normal in the UK...

 

They sometimes have a growth spurt, due to the varying conditions as mentioned, and the leaves furthest from the moisture/nutrition take a little while to catch up with the rest of the plant. It isn't usually a problem at all.

 

Been eating Sweet 'n' Neat Scarlet and Bloody Butcher this week. Prefer BB but look at Sweet 'n' Neat Scarlet! There's more fruit than plant. I've put it on my garden wall to show off to passers-by.

 

Hoping someone can tell me what’s wrong!
I have been growing tomatoes for many years but that does not mean I am an expert, far from it!
As I live in Scotland I only grow tomatoes in my greenhouse and grow the majority in the soil beds. Every year I exchange some of the soil and then replace with rotted horse manure and all has worked well for many years.
This year the tomatoes were slow like with everybody else but were growing away well eventually and I have some trusses which should be ripe within the next couple of weeks. However, all of a sudden the new growth on some of the tomatoes is misshapen and not looking well at all while the rest of the plants look fine. Other plants currently are unaffected. It looks like it could be related to weedkiller but I have not used any anywhere near the greenhouse and have a specific sprayer just for weedkilling.
The only thing I can think of is that a flaming livery person who rented our field last year insisted on having the field sprayed to kill Sycamore seedlings which all of a sudden can be lethal to horses ( hmm maybe as Sycamores grow like weeds everywhere throughout the UK and I have never heard of a death of a horse through sycamore seedling poisoning, we having had our own horses in the same field for over 20 years with no problems). The weedkiller used was Doxstar which is a broadleaf weedkiller. Could this be the cause and if so why is the damage only showing now?The manure used will be from grass consumed which was sprayed last May. The tomatoes were started in a heated propagator in March and planted out in the greenhouse around the 2nd week in May. I will be livid if I loose the lot as have over 25 plants. The cucumbers growing in the same soil seem unaffected atm.
If it is not weedkiller issues then I am completely stumped. First 3 photos are of plants affected. Fourth shows one that is fine and photo of cucumbers which are also ok.

 

The product you mention contains fluroxypyr ,and also triclopyr systemic which causes accellerated growth, and death to broadleaf plants.There should be a withdrawal period of 28 days for livestock when this product is applied.Do you know if the person applying it was professionally qualified to use it?
It seems likely that your plants have grown into a contaminated manure, it may be fatal, but time will tell.
