Territorial Tomatoes?
Well that's one theory. A horticultrual noob, I'm prepared to believe
anything that's either true or amusing. I have a couple of Alicante Tomato plants in the conservatory, climbing 8ft canes which are lashed at the top to the rafters, and one of them is now taller than me. That's about 1.75m or 5'9". I expect they would be even taller in a greenhouse. The smaller of the two plants has developed yellow mottling on the leaves, originating between the veins, but then spreading until the leaves die off. Working on the theory that this is due to a magnesium deficiency, I have obtained a different brand of tomato food (J. Arthur Bower's), which has 0.048% Mg content, as compared with Tomorite (Levington), which has 0.018% Mg. D.G. Hessayon (The Vegetable & Herb Expert) confuses me a little, as he suggests that this is made worse by standard feeding. I've been unable to get my hands on Mg-based fertilizer or epsom salts, so I've switched to the Bower's feed for the time being. This yellowing of the leaves is progressing from the lower stem upwards as you might expect, but the interesting part is that it's occurring absolutely consistently in the 180-degree arc which *faces* the other plant. Though it seems unlikely, it makes me wonder if tomatoes compete for space in some way once they get to a certain stage of growth. The 2 plants are 2'6" apart, which is quite close, but the leaves were never touching, so they didn't *seem* crowded. Any observations would be welcome, especially on how to remedy plant B, which is completely healthy on the East Side, but has plant A to the West. --Neil. -- Neil Trotter, Canewdon, UK |

Thanks, Ron :-) It's my intention to call there next time I do a run into town -- I thought I might find them in the liver salts area at Waitrose, but like erasmic shaving sticks, it seems they may be one of the old-fashioned commodities only found these days, as you suggest, in chemists. --Neil. -- Neil Trotter, Canewdon, UK |
