Yellow Tomato Leaves
All the leaves on my 3 tumbler tomatoes have turned completely yellow, but
the leaves have not dropped off, nor have they shrivelled, nor have they dried up. The leaves have turned bright yellow, no mottling, but some of the leaves do have a few brown spots. Today I stripped off all the leaves completely as I figured they weren't of any use and if it's a disease it might spread. The 3 plants are in one hanging basket but the basket has not been hung up; it's been kept on a greenhouse bench. The soil has been kept constantly moist (possibly too moist?). None of my other tomato varieties are like this. I've put up a scanned image of one of the leaves, if anyone would care to look and let me know what the problem could be. I did overdo the fertiliser once, so could it be fertiliser burn? When the plants first started to yellow I sprayed them with epsom salts. Also, there are several small green tomatoes still on the plants so if these tomatoes ripen will they still be edible? The image is at http://homepage.ntlworld.com/melanie.mccluskey/ Many thanks. |

Yellow Tomato Leaves
Quote:
from what you`ve said, it`s quite possible the roots have been damaged, toms like alot of feed (high potassium especialy) but they`re not gross feeders, and so it is possible to "scorch" the roots a foliar feed of ammonium sulphate or ammonium nitrate, would provide a nitrogen boost, but I somehow think it`s a bit late for the poor chap good luck, I`de love to know the results of your toms IF they ripen, and yes, they`ll be perfectly edible if it`s a mineral deficiency. but if it`s been caught downwind of a herbicide spray (and it looks a bit like that) then I wouldn`t risk it.

In the absence of disease, sounds to me like a mineral deficiency (from what I've been told). Trouble is, at the moment I can't remember which one! (I _think_ it's magnesium - I'll refer to this magical ingredient as XXX below...). Month or so ago I was in the local garden centre, looking for organic tomato food. I couldn't find anything organic on the shelves specifically marketed as tom food, so I looked at the makeup of one of the non-organic tom foods, it was something like 4-3-8 NPK, i.e. a high potassium fertilizer. Found an organic fertilizer with a similar makeup. However, the propriatory tom food had "includes XXX" on the label. Asked one of the staff about this, and their reply was that yellowing leaves was a classic sign of this deficiency, and if this happens just use one of the specific XXX fertilizers to restore the balance. It gets washed out of the soil due to the large amount of water that toms need. I'm sure that someone can confirm/deny this... -- Richard Sampson email me at richard at olifant d-ot co do-t uk |

I was told that as I used a compost recommended for hanging baskets, I should be giving my toms double strength of liquid tomato food over the week, thus doubling the magnesium and giving them extra disease resistance. This I have done for the past two weeks, and I am happy to report that there are no more yellowing leaves. Bella |

(I _think_ it's magnesium - I'll refer to this magical ingredient as XXX below...). Yellow patches are typical of magnesium deficiency and you need to choose your tomato food with care because some of the Discount Shed own-brand swill doesn't include it. But your pictures are of something far more extreme. But have you overcrowded the plants? We only ever plant two tumblers to a basket - if you overcrowd them all you do is reduce the size of the crop. We normally add Westons granular feed to the compost, which gets the two plants in each basket going like Jack's beanstalks! We still feed every other day with Tomorite. This year the crops have been so heavy that we have had to take the baskets down from the greenhouse ridges and put them on column stands. (Just finished enjoying tea - free range egg omelettes with tumblers straight from the greenhouse along with Marshalls experimental lettuce and home-grown beet. Scrummy!) |
