TOMATOES


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 need feeding. 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 also 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.

A general all round fertiliser grows most things.

my tomatoes are being bored into with some sort of caterpillars also some with black spots any ideas on how cure this organiclly or failing that anything to stop it ???

Look up natural sprays for caterpillars and Qld fruit fly on the internet. The holes caused by pillars and black dots are probably qld fruit fly. Chemical for QFF is LEPIDEX.

Hello to all at Gardenate, I see that you say that tomatoes can be frozen, but it is my experience that on thawing they go all soggy, and will not hold there shape, is this correct. Have a great day, Allan.

If frozen I don't think you could use as a fruit to slice etc. I think you could make sauces or similar.

I'm looking to grow cherry tomatoes close to my sweet Peppers and wondered if they are compatible together? Can't seem to find an answer on the net.

If you can't find anywhere where it says don't grow next to each other then I would assume it is OK. Just give each crop it's room to grow. Think where the sun will be throwing shade during the day. You don't want the tomatoes shading the caps all day.

I'm having problems with grub's in my yard and garden. Has anyone ever used a spray called milky spore. If any one has how long does it take to get rid of them. The moels are reeking havock on everything because of them. Dogs digging after the moels is a completely different story and problem. Any advice would be appreciated thank you.
