There is nothing like the taste of a freshly picked tomato, warm from the sunshine. In the smallest of gardens or even an apartment with a window-box, it is worth growing at least one tomato plant for the pleasure it will give you. They will grow in pots, troughs or even hanging baskets.

Tomatoes should be grown in shelter or under cover in cool climates.

Tomatoes like lots of food! In a garden bed, compost and mulching will produce a crop from one or two plants. In containers, use some suitable long term fertiliser pellets or feed regularly when you water. Feeding improves the flavour of the fruit.

When you plant out, put the seedlings in a deep holes, up to the top set of leaves. The covered stems will put out extra roots and you will have a stronger, healthier plant.

There are many different varieties of tomatoes but they all have one of two growth habits.

Determinate:

Compact bush growth, stops at a specific height and useful for containers. If left without supporting stakes, they will form a dense carpet which excludes weeds and keeps the soil cool and damp.

Indeterminate:###

Will continue growing a main stem, or vine until stopped by frost. The majority of heirloom tomatoes are indeterminate.

Both types need stakes to give them some support otherwise they will sprawl across the garden.

Varieties include Acid-free, Bush, Tall, Cherry, Yellow and many others.

Culinary hints - cooking and eating Tomato

Use in sauces, with fried meals, in sandwiches. Can be frozen whole or in pieces.

I sow mine in late Sept in trays which i then put in the bottom of a large Sistema container with lid...I pop this out in the sun during day...moving lid around for heat and close it at night...if really cold pop in shed with a blanket....or do the same in the tunnel house....it double walls/protects...you can always throw a rug over the sistema for extra....in the morning undo the sistena and before long you have healthy plants. When planting out, i use cardboard boxes to cover at night, as less condensation and if really cold night.....pop that big Sistema over the cardboard box...really helps with protection. Had great sucess over the last few years. Also put sheep dags over the soil in the winter and dig them in before planting out...great microbiome and nitrogen for soil.

Hi I live in Central Otago and have a variety ot tomato plants that have flowers but no fruit. Am I wasting my time, will they produce fruit & ripen?

I find the shorter growing tomatoes like early girl do much better - anything longer than 8 weeks seems to only just have fruit at the end of the season and then no time to ripen

It says plant spring/summer, give them time to grow.

I sow tomatoes in Nov. the tomatoes are still green. Should I leave them on the vine and let them ripen indoors?

Just let them ripen - it takes awhile.

Can you please recommend a tomato variety which will grow, in-spite of cool nights (WANAKA)

Are you cool mountain or temperate. That will determine your planting time. Plant whatever variety you like.

Will a plastic grow tent protect seedlings from frost
