Mine are the same! I grow Sweet Bites and Tomatoberries in large pots, but they end up dying from the bottom up with leaves on the new growth. My soil is rich and I regularly use worm castings/juice and potash-rich fertilizer. Kellie, Sydney

My tomato plants always die from the bottom up. The leaves yellow then brown then drop off. Plants develop well, and I keep it in check by removing diseased leaves, but by the time tomatoes are ripening the plant starts to die. If I don't pull the plant while mist fruit are green the fruit go bad. Does anyone know what thus is? How can I stop it? Sarah, Perth, temperate

Hello Sarah. I'm no expert, but, how is your soil. If it is nice and rich, you shouldn't have any problems. Maybe you need to replace the soil, then build it up with compost etc. My plants were like that, so I replaced everything for this growing season. My 16 tomato plants are now well over 6ft. tall and 'loaded'.

I have tomatoes at 1.5 metres and the fruit is large on all plants. The problem is the plants look like they are starting to die off before the fruit ripens. We have chook so i have placed the waste on the ground around the plants ( the waste is a week old before it goes on). Suggestions please.

we've had so much rain, the soil in places is boggy but my tomatoes are in a new slightly raised bed. I've noticed blossom end rot on many of the plants. I guess the calcium has been leached out of the soil with all this rain, should I add some lime?

From experience night temps will stop flowers from bearing fruit. We in Armidale (Northern Tablelands NSW) have experienced 1 C over the last few weeks at night. However, I have pot plants in a secure under the eves and one self seeded plant lived through winter, and has beared a few fruit. Not the most healthy looking either. But has three tomatoes on it.I don't think Armidale is the best place to have tomatoes unless in a green house. They grow well but don't bear much fruit, as night time temps go beneath 10 C.

Hi David.. Whitefly can be controlled by using a low toxic product called Natrasoap. It suffocates the pests, then they dry up and fall off. You can also add a few drops of Peppermint or Eucalyptus oil as well.

Help!! Dear All, I live in St Kilda in Victoria, my Tomatos which are only a couple of feet high are covered in clouds of whitefly, Ive tried everything, concoctions of sunlight soap and vinegar, pyrethrum, you name it but nothing seems to work. I have heard companion planting in conjunction with at least one other method is the best way but as i have tried so many different methods, i am somewhat sceptical. Does anyone have any tried and true methods to stop whitefly (other than not growing tomoatos)?

Hi David, I'm not sure if you have found a solution to your whitefly problem, but I thought i'd post this anyhow. I haven't tried this yet, but I saw a great segment on GA ages ago where Colin uses a vegemite 'tea' to attract lacewing, whitefly's natural predator. I found the fact sheet for you, but I can't post it. Just google it: Gardening Australia, fact sheet 'home-made remedies', series 20, ep 22, Presenter: Colin Campbell, 27/06/2009 Also, basil is a great companion plant to tomatoes, I tend to interplant them between rows. I hope this helps, and isn't too late!

I think you might have blossom end rot, and root rot mixed up. Blossom end rot occurs on the base of the tomato, and is caused by a lack of calcium (usually -- it could be other things that cause the calcium to be unavailable - PH, lack of water etc.). Blossom end rot causes the tomato to look deformed. Calcium added to the soil at the time of planting is usually adequate to ensure this does not happen. The calcium really needs to be added EARLY in the growing stages. You could also use egg shells -- I would grind/smash up the shells pretty good then work them into the soil of the planting hole; better yet, enrich with egg shells over the winter and early spring in anticipation of future planting. Root rot usually occurs when water sits around the roots of a plant for long periods of time -- bad drainage, excess watering, soil that holds too much water (which is really drainage). If you have proper aeration this usually doesn't happen since the air flow will whisk away excess moisture (provided it isn't a swamp at the roots). Try to create updrafts in your pots -- you want water drainage holes that do double duty -- let the water run off and allow air in. I find that holes at the SIDE BOTTOM of the pot, rather than directly under the pot, work well. It may seem like a hole at the side of the pot will let the soil out -- but pretty much after the first watering this stops happening -- and once the roots take hold it certainly does not happen. No need for drainage material (stones etc.) -- just use soil/compost top to bottom -- expect soil to come out at first when filling the pot -- after that you should be fine. I make my holes rather large -- on a BIG pot these holes are about 3inches (circular). Roots of plants really like air (maybe not direct exposure) but they certainly like the occasional breeze through the soil. Face the hole on the shady side of the pot for a cooling updraft in hot weather.
