  • Newbie tomato help


    This is my first season growing tomatoes and I have a problem on all of my tomato plants. As can be seen on the photo, I have little black areas appearing on the leafs. I've googled extensively but can't quite seem to find something that describes this. Initially I thought it may be a pest problem so I sprayed with a natural pesticide but the problem continues.

    Could anybody point me in the right direction to what I'm dealing with?

    Hi Findai and welcome to the Vine
    Is this mostly on the bottom, oldest leaves? If so, don't worry, its natural. They're dying off. I cut the bottom leaves below the below the first truss of flowers/fruit off anyway.

    I don't think its a pest problem but do you feed them? If they're in compost, they need feeding after 6 weeks as all the nutrient in the compost will have been used up.

      Mine look like that too, it's normally on the older leaves I find. I just cut them off.

        Its the start of magnesium deficiency. Give them a good feed of tomato food (high magnesium). Don't expect the discoloured leaves to recover, but newer ones should be fine.

          Thank you for your swift responses.

          It's good to hear that it is normal. I'm approaching fifty and never did I expect that I would worry so much about some plants! I can see that tomato growing could easily become an addiction!
