My tomatoes are growing well, but they have started to exceed the 7' mark. Can I cut of the top of the bush so its not as high? Will this increase lower growth or will the plant go into shock and not produce?

Hi Dani, Sounds like they need a good fertilizing. You can take the new shoots from between stems and replant in seedling mix to keep over winter (inside). Otherwise tear out, plant some beans and then start over again in September. Good luck!

I read that tomatoes shouldn't be fed until fruit starts forming, otherwise you end up with lots of lush leaves but no fruit. If the plant is too well fed it doesn't feel the need to reproduce itself. I always plant in good soil but don't feed until then.

Are there anybody around North-East Melbourne who would like to swap seeds/seedlings? I live in Greensborough. :)

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.
