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.

Hi, I want to make homemade chutney using good tomatoes. When are they in season in Melbourne/Victoria please?

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.

i have just planted 4 different types of tomatoes roma hybrids big red should i put chook poo on them and what other fertilisers and which is the highest yielder

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.

Your Blossom end rot could be caused by the small pot. Try a 30L minimum for a tomato of up to 1m, and 50L+ tubs for anything taller. The problem in Northern NZ (Auckland upwards) in the intense heat, humidity, and constant winds on clear days that dry the soil. The soil seesaws from dry to wet, with us trying to compensate the loss three times a day, in small pots. You'll get excellent plants, but blossom end rot, and no useful fruit. I buy seeds from Southern suppliers who have clearly defined seasons in their districts. Here in West Auckland, the sun mid-spring onward is almost too strong for tomatoes (as noted in the comment from The Shore above), and the humidity is oppressive. They are part shade plants here, and 30L is absolute minimum for varieties that suppliers claim can be grown in 18L, or less. This year I'm using no less than 54L each plant, plus grass clipping mulch. So far so good. It's the only way to maintain soil a consistent moisture.
