Whilst crop rotation is important, it doesn't seem the whole answer. We have a raised bed, no dig garden, built on bedrock and layered last winter with manures, lucerne etc. So no prior soil, let alone where tomatoes had been. Despie using the preventative milk spray on first signs, wilt has taken out two plants already, which still had a light harvest, and is close to killing a third, though it's harvest continues well. More experienced gardeners (this is just my second year) have said it's inevitable in Sydney and just to hope for some harvest before the end of the plant. I'd appreciate any other tips. My Dad suggested a copper sulphate spray, but we garden organically.

Thanks Barb ... novices are always keen but boy I lack knowledge. I'm trying to companion plant and not use pesticides (except my garlic mix). Also heard that "solar sterilisation" will kill organisms - black plastic over bed before planting - weighed down and let the sun kill off the bugs. Oh well, there's always next year! Barb is there anything we can do now to save our tomatoes? Any advice would be greatly appreciated. Cheers

Tomatoes and others in the solanacae family (eggplant, capsicum, potato, etc) should be rotated to help avoid wilt diseases and also root knot nematodes - these build up in the soil. Sadly boiling would kill a lot of the good microbes - crop rotation seems the best approach of all. It could even be tomato russet mite that's causing the yellow dying leaves - they're microscopic (invisible to naked eye). Keeping the tomato plants growing well with healthy compost, regular feeding with organic fertiliser and plenty of water does seem to help.

I agree. I have put the tommies in new garden beds - maybe I should start checking Ph levels - never have before but always had success. But I guess more effort (and money for ph testing kit) just may pay off. Boiling water - sounds interesting! Thanks.

Annalisa, I'm doing some research on the wilt thing. One site said never plant tomatoes in soil that had previously had tommies grown. No-one down my way has had success this season with tomatoes. Perhaps there's credit in the boiling water prior to planting theory. Too bad this site isn't frequented more - I really like it but don't get too many answers.

Planted tomatoes they have fruited but no colour coming. Also the plant seems to have a blackish/brownish tinge to the trunk, is this bad.

Anxiously awaiting answers about wilting. I had success last year with tommies, and this year, all five plants had to be ripped out with green tommies all over due to disease. Is it in the soil? I use seaweed fertiliser... Pretty tired of fighting this thing, but willing to fight on. I want some healthy tommies!

Just south of Wollongong NSW, my beef steak's are about 6ft tall and were very slow to show flowers. Now I think I have a wilt fungus as the bottom leaves are turning yellow and dying. What do "they" mean when they say you shouldn't grow tomatoes in soil that previously had tomatoes in it? Perhaps the boiling water idea in November. Apparently eggplants are also affected by the same wilt - Vermillician or something like that. Any help or ideas guys? Cheers

I have grown my tomatoes from seed from big tomatoes yet all five bushes are growing small cherry tomatoe size fruit lots and lots of them, what have i done wrong?

John - by any chance is it possible that you live somewhere close to Melbourne? Would like to see your savagelly clipped tomatoes. Grandmother (63) (interested ONLY in gardening)

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
