I assume you are trying to grow the same variety of tomatoes. Any crop requires sunlight, water, nutrients and something to grow in - soil, water etc. 1. Tomatoes need good fertile deep soil. They need DEEP watering every 2-3 days. A little ground spray line just doesn't do it. A few comments back I gave some tips on growing tomatoes. Some people recommend you dig a trench 400-500 deep, throw in some fish heads/backbone etc, aspirin, Epson salts, compost/fertiliser. Put some soil back in and add some more compost/fert and mix it up. Still with the trench 200-300 deep plant the seedlings. As they grow fill the soil back in. Tomatoes are deep rooted so fert and water deep. 2. Zucchini need plenty of water also.

A few tips on growing tomatoes - make sure you have good rich prepared soil. Dig a hole 50cm deep and 60cm diameter. Put compost/manure into the soil or a hand full of fertiliser and mix it in. Plant the tomato in a bit of a hole and as it grows fill the hole in. Give tomatoes a good deep watering. Too much N and you will have a lot of leaves and little fruit. Too little fertiliser and you will have a small plant and a little crop. The secret is to know how much fert to put on and when. And start with a good strong seedling.

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.
