Tomatoes – a mans best friend

Tomatoes – a mans best friend

Growing tomatoes in the vegetable garden is a great challenge. There is a sort of unwritten rule for vegetable gardeners; if you grow good tomatoes the rest of the garden must be good also.

The art and science of growing great tomatoes is actually very simple.

Glasshouse tomatoes
During early spring use a fork to turn the soil and make it loose and friable. Apply a liberal amount of compost to the surface. Some people like to dig this in but it is not necessary. Keep it weed free.

Purchase your tomato plants from the garden centre or you may choose to sow your own seed. (see seed sowing). When selecting your tomatoes make sure you get nice strong healthy ones. They should be dark green, with plump stems and just a hit of purple at the base where the roots appear.

When all signs of frost or really cold weather have gone plant them out on your glasshouse about 40cm apart. Add some slow release fertiliser or blood and bone to the soil and water well.

Keep the glasshouse temperature even. The main thing that a glasshouse does is prevent wind damage and stops cold air disturbing the plants.

As tomatoes are climbers you will need to attach strings to the roof and tie the string to the bottom of plants and twist the plant around the string periodically. As you do this remove laterals (side shoots) to encourage upwards growth and better fruiting. Some people may let the main shoot and one other strong lateral grow to produce fruit.

Manage the glasshouse so that it does NOT become a hot house. Tomatoes require a even temperature not hot conditions. Leave the vents open for good air exchange to prevent disease build up.

Water the plants well and regularly. Do not let the soil dry out and then saturate it. This is the cause of a problem called blossom end rot of the actual tomato fruit. Regular watering is best.

As the plants grow the bottom leaves will start to turn yellow. These can be removed. This will let light into the ripening tomatoes.

Pest will appear later in the season and ill include white fly and looper caterpillar. Spray these with your organic or traditional insect spray.

Should the plants look like they need some extra fertiliser use a general purpose fertiliser that does not have too much nitrogen in it.

Commonsense and care and attention to glasshouse hygiene are keys to success with tomatoes.

When ripe pick the fruit and enjoy.

Outdoor tomatoes are even easier. Select a sheltered part of you garden away from strong cold winds. Prepare the ground with lots of compost. Plant out a row of tomato plants about 40 cm apart. Insert a sturdy stake to tie the tomato plant up to as it grows. Some people prefer not to remove all the side shoots and have it spread out and not become too tall. The choice is really dependent upon how much room is available in the garden.

Again keep up a regular watering. Removal of yellow leaves and some side shoots will keep fresh air moving through the plant and help prevent a build up of pests and diseases.

Once again good care and attention will provide large rewards.

Hi Alan,
Thanks for the advice... The ground is still solid about 2 inches down, so will have to be patient until I can get my garden going.

I wanted to know what staking system you use for your tomoatoes? I have tried everything and now excited with a new product I found at www.thetomatostake.com Simple, plastic stake with twist ties already on it.

Best of luck!
