For the fourth year now I have had tomatoes with black at the bottom in my greenhouse, I scrub the greenhouse with Jayes Fluid, use new fertiliser and feed and water them



This is usually a sign of erratic watering. Do you water them every day?

Yes I water my tomatoes like clockwork, have grown them successfully for about 30 years plus but this past 4 years some of them are black on the underneath of the tomatoes!

Hi again - I have another possible cause - lack of calcium! Try to use a feed which contains this element, and I hope it helps.

How do I say thanks?
