I have used old clothes sheets towels all my life. I'm now trying a couple of posts with wire mesh between them. Train the plant in and out of the wire mesh and can use twine etc to support them also. Saves having dozens of pieces of cloth.

Hi I love tomatoes but don't have any luck growing them without white fly or aphids impregnating them. I've tried white oil but with no luck. Does someone out there have the solution as I love growing them and especially eating them. Cheers

Try a mix of LUX soap flakes. Mix 2 table spoons of flakes with 500mls of warm/hot water. Then mix with 5 liters of water and spray both sides of the leaves - do this every 4-5 days. Do the leaves curl up and not grow? Try growing in a different spot. .

You could probably grow tomatoes all year round. Maybe better to plant some good strong seedlings - like about 6-9" tall. Next year plant a bit earlier. I transplanted some small seedlings out 2 days ago. If your soil is nice and fertile mulch around the plants and keep the water up to them.

Hi guys, do we need to do plant successive crop for tomato?

Bush varieties (determinates - like Roma) of tomatoes will produce a crop all at the same time basically. Where as indeterminates (cherry) will produce over several weeks/months. Yes you need to plant successive crops if you want to be picking all year.

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.
