April has started now and I"ve just picked one ripe fruit. Am I waiting for nothing? Will they ever ripen. I've got 100's of green tomatoes. I also noticed one of my plants is still flowering.

my tomatos ripened very slowly too, but they eventually got there. I only just started harvesting them a week ago. I have not had problems with birds.

I had the same issue issue last year and a friend suggested hanging yellow and red christmas baubles on the vines before it starts fruiting. Birds will go for these first without success and, hopefully, leave your ripening tomatos alone. That's my plan for this year, anyway.

I'll try that on my plum trees next year!

I am no expert, but I read somewhere that you can put banana skin under the mulch or in the soil and the potassium helps with flower production. I tried this and also made a tea of banana skins which I apply (diluted) weekly. It seems to work! There are lots of flowers and fruit even though we have had a very slow start to summer here.

Hi my tomatoes are growing OK , but are not showing any sign on flowers, I have had them in for weeks now.

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.

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.
