are there any signs of rot on the stems , help them along with 2 tablespoons of Epsom salts in five liters of water every two months. losing of flowers usual has only two causes , a shortage of water and or shortage of minerals , therefore ensure that water is provided and don't water the foliage but soil level , but don't over water them . Epsom salts seems to be a wonder solve them all. red spider mites lay there eggs in the stems of your plants check for any signs of damage,on the stems.

You grow wrong type for your climate. Try a good heirloom such as Reisetomate or a cherry tomato such as yellow pear.

I have been told that some varieties of tomatoes can be grown successfully in winter. Has anyone done so? What varieties can be used and what special provisions...e.g. frost protection?

Cherry tomatoes are possible to grow in low frost areas during the colder months providing they have a nicely sunny position. Water in the mornings to prevent drenched soil at night. Start them off in seed trays under glass or in warm area .Ensuring the soil is rich in organic matter will heat the soil slightly as it continues to compost. I find that cherry tomatoes can tolerate the early spring including very late winter and late Autumn as they are small and do not need as much sun to ripen. Although I have not grown tomatoes in the middle of winter the local community always has them growing. Did you end up growing them and how did you go? Happy gardening - Elizabeth

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.
