If you set your climate to summer rainfall and look in tomatoes, it is right in front of you, plant SEPT TO MARCH.

To keep the slugs, caterpillars from Tomatoes and other vegetables away break egg shells up and spread around plants. Works great

We have been experiencing very hot, dry days. Up to 42 degrees Celsius. Could this be the reason that my tomato plants died? They were watered regularly & kept in the shade.

I think it could just be seasonal. My tomatoes were going great (Nov and into Dec picking) and towards the end the whole plant just died off quite quickly. Same conditions as you, hot weather. In a lot of crops you can have early mid and late season varieties.

My butter beans plants are producing lots of beans that are growing and then curling up at the ends. What could be causing this and can i treat it with a fertilizer or a spray? I also have Zucchini that the flower covers all of the end rather then the tip they grow about 3-4 inches and then go yellow and shrivel up?

Research on the internet, what causes curly beans. Go the Gardening know how webpage and read. I think the zucchinis are a bit of a mutated seed or whatever. I had a plant like that, big fat end zucchinis with a big flower. Sounds like the female flowers are not being pollinated. Try it by hand.

something is eating my tomatoes as soon as they get a bit if pink on them. Any advice or assistance. We have put up netting to stop the birds but still happening

Check the plant day and night for grubs.

Look under the leaves etc and see if you can find grubs etc.

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.
