I have good success with oxhearts and rouge de marmande. They fruit all through winter too and I'm more southerly than you. You can get these varieties in DT Brown seeds from Reject Shop for $2 a packet. Mine self seed after the first season and I'm about to harvest a pair of oxhearts weighing 300gms each. They don't seem to revert to wild tomato types when self seeding which a lot of other varieties do. Cherry toms are prolific fruiters and easy but a PITA to harvest and not useful for sandwiches. But perfect to toss into a salad. I prefer the larger types. I harvest the toms as soon as I get a small blush of pink/yellow on the skin and then they ripen perfectly inside without inviting pests. But you need to let them get the colouring enzymes going on the vine first in a small amount for this to work.

I never use anything and get large crops. Maybe I am just exceptionally lucky? Who knows.Try tomato fruit bags. These are fine mesh bags you tie over the green fruit trusses that prevents insects from getting at them. If you can sew you can probably make a heap out of an old fine net curtain to save $$$ as they tend to be rather pricey to buy. Just a rectangular bag with a drawstring large enough to house the truss.

Tomatoes grew well last season until whitefly arrived. I found that Pyrethrum spray only reduced the numbers for a week or two and then it was basically ineffective. Suggestions as to effective control?

I basically only grow cherry tomatoes, they are fairly disease resistant. Bigger tomatoes the fly and grubs just feed on them especially when the warmer wet weather comes.

A question about beans in the tomato section. Beans (dwarf) about 300-400mm. Bush tomatoes 1m.

Last year I planted cherry tomatoes from seedlings in January. I saved some seeds. When and how should I plant the seeds to develop seedlings for the coming year and how do I plant the seeds?

Plant in a fine potting mix or similar soil (light and free draining) or a mixture of soil and potting mix about 1/4

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.
