Introduction

Growing Tomatoes is one of the most rewarding gardening activities and an easy way to start children gardening. They are easy to grow and quickly provide the freshest of tasty results. Tomatoes can be grown from seed or are readily available as seedlings. For information on grafted tomatoes see the Mitre 10 Guide Growing Grafted Tomatoes.

When to Plant Tomatoes

The weather rather than the calender date, is the determining factor. They generally need three months of warm, frost free weather to produce well. With protection plants can be grown from August onwards. Labour weekend is the traditional time for planting tomatoes but they can be planted outdoors as soon as conditions allow, usually any time from September onwards.

Soil and Position

Tomatoes need plenty of sunshine. Any free draining soil which is rich in organic matter is ideal. Tall varieties need protection from strong winds. Against a wall, fence or trellis is ideal. Prepare the soil by adding liberal amounts of compost and digging through deeply.

Planting

Tomatoes are happy in containers or planter bags. Stake and train as you would plants grown in the garden. Use a specific container planting mix. Take extra care with watering and do not let the soil dry out. When planting add a small handful of Results Blood and Bone to the soil.

Plant seedling tomatoes at least 40cm apart. Prepare the soil as per above. Water the plant in it`s container and allow to drain. Plant without disturbing the rootball. Firm the soil gently. If planting seedlings from a punnet, first remove from the punnet then gently separate the seedlings.

Staking - Only the taller varieties require staking. It is a good idea to position stakes for all varieties at planting time to avoid damaging the roots later on. Overhead wires with strings to climb up can also be used.

Training - This depends on the type and variety of tomato. Tall varieties need pruning to aid air circulation (which prevents disease), to let in maximum light and to concentrate the plant`s energy on the main leaf structure and the fruit. As the plant grows remove all lateral growths as soon as they appear. These appear between each leaf and the main stem.

Feeding and Watering

Tomatoes with their rapid growth rate are both thirsty and hungry. It is very important to water regularly in dry weather. The plants must not be allowed to dry out. Mulching is an excellent way of conserving moisture in summer. Compost is ideal for this purpose. As plants grow and become loaded with fruit their requirement for water will increase. Once the small fruit appear supplement your initial ground preparation with a fortnightly feed of a balanced fertiliser such as Tui Tomato Food. This fertiliser is high in potassium to encourage fruit set. Water thoroughly after feeding.

Harvesting

It is a good idea to pick fruit before it is fully coloured and still quite firm. This helps fruit keep longer and relieves the plant of its load allowing it to keep on the job of producing more crops.

Pests and Diseases Minimise problems by:
	Changing the site or replacing the soil of sites used previously for growing tomatoes.
	Pruning to encourage air circulation which helps deter diseases.
	Remove foliage or fruit showing signs of disease.
	Planting grafted tomatoes. These are grown on disease resistant rootstock.
	To control blight spray fortnightly with Champ DP, or make that a weekly spray if it`s hot humid weather.
	For white fly spray with Mavrik.

Fight Heart Disease
Medical research shows that tomatoes could be the key to preventing blood clots that cause heart disease and strokes. That`s because the yellow jelly which surrounds tomato seeds helps keep platelets in the blood from clumping together, therefore eliminating the risks.
