Potassium Deficiency In Tomato Plants
Some of our tomato plants have taken on a definite tinge of purple since planting out at the beginning of June, they are also not growing as well as might be expected and in general look a bit sickly. A quick romp around Google, what would we do without it, reveals this to be a deficiency in potassium.
The RHS have an interesting perspective on this saying that it’s worth remembering that tomatoes are tropical plants and whilst it might be June, as it was when I rang them, night time temperatures will still only be in the high single figures. The plants find this cold and it therefore inhibits their metabolism of nutrients from the soil.
As the plants have now set some fruit I’ve started feeding the plants with Tomorite and I’m hoping that this with some warmer weather will resolve the situation
If you have had this problem I’d be very interested to know your thoughts.
