How to stop tomato plant leaves turning yellow?

[DayDrew1983]

hi everyone, we are trying to grow tomato’s on an arch, the first tomato plants leaves are starting to yellow, I feel like it’s spreading to the second tomato plants. How can we fix this issue, the leaves are turning yellow and then die. Hope the photos help?

Hi @DayDrew1983,

A warm welcome to the Bunnings Workshop community and thank you for your question.

There's a good chance this is just the natural aging process considering the newer leaves appear to be lush and green.

I'd simply remove the old yellowing leaves so energy is directed towards the new growth, apply some Tomato Vegetable And Herb Controlled Release Fertiliser and give your plants a good drink.

Check out the series on How To Grow Tomatoes for further information.
