Any one tried growing tomatoes all year round in a tropical climate using a raised garden that does get shade during our hottest part of day???

Damian I think you will find that brown patch is blossom end rot which is caused by uneven watering.

Last year my tomatoes started really good. Then the foliage seemed to turn black. We didn't have a frost. I didn't get any fruit at all.

Gareth, you can use chook poo but it is very strong and can damage plants if used fresh. Make a 'tea' with it by putting in a bucket of water and leaving it for a few weeks or else use chook poo mixed with compost and broken down.

i have found . if i get some electrical wore. take off plastic coating... then get individual strands of copper wire, and cut to about 2 inches long. then force 1 of these thru each tomato plant at the base .. it gives some protection against disease, but wouldnt be prctical for commercial growers, just home gardeners

Hi, I've been planting tomatoes for the last 2 years with success. However, last years fruit were a bit powdery. Any tips on how to stop that? The only thing i add to the soil is compost and occasionally soluble plant food. thanks

Steve: it could be that the soil has been drained of its nutrients because tomatos take huge amounts of nutritions perhaps put some beans in the soil as bean put nutrients into the soil

I didn't have much luck with tomatoes this year. They just seem to wilt and die. I can't see any evidence of pest or disease.

I live on the North Shore, Auckland and have done container growing for several years now, This is the third year of growing tomatoes on a large scale - predominantly determinate varieties. I source my seeds from Kings Seeds who supply a determinate variety called Sub Arctic Plenty which I have experimented with variable results. All plants raised indoors, gently hardened off then potted out into 15L tubs. I use 50/50 new compost/previously used container soil from a non-tomato pot mixed well with added slow release fertiliser and half a cup of powdered eggshell.. The top is mulched with straw and 4 marigolds to attract the bees. They also need a 5ft stake. Generally the plants like the morning and late sun and need shade from the glaring hot midday temperatures. Each year I am growing them earlier to avoid the heat of summer. The pots on the decking facing North fully exposed struggled, the pots that were shaded midday grew much better. Next year I plan to plant out in July/August and see how they get on then. They have a mild taste, personally I prefer the richer flavours of the dark toms but they are good for dehydrating. I also found that they prefer dryer soil than some of my other varieties. I liquid feed them once a week using a litre of water. Don't let them stand in trays, they need full drainage. Any run off from the trays I use on something else (the pineapple sage is very grateful). Spay every part of the plant with a brew of bicarsoda to pre-empt and control powdery mildew weekly. Please let me know if you want any other info - happy to share. Let me know how you get on.
