What Are Determinate Tomatoes?

Determinate tomatoes are often called bush varieties.

They:

• Grow to a fixed height
• Produce fruit over a shorter period
• Require little pruning
• Often mature earlier

Once they reach a certain height, they stop growing taller and focus on fruiting.

Advantages of Determinate Tomatoes in the UK

Determinate types are ideal for:

• Outdoor growing
• Pots and containers
• Small greenhouses
• Beginner gardeners

They are generally easier to manage and require less maintenance.

They are also often earlier cropping, making them suitable for shorter UK summers.

What Are Indeterminate Tomatoes?

Indeterminate tomatoes are also known as cordon varieties.

They:

• Continue growing taller all season
• Produce fruit continuously
• Require regular pruning
• Need strong support

In a greenhouse, they can grow well over 2 metres tall.

Advantages of Indeterminate Tomatoes

Indeterminate types:

• Produce higher total yields
• Crop over a longer season
• Perform extremely well in greenhouses
• Are often used for cherry and beefsteak varieties

If managed properly, they provide continuous harvests from mid-summer to autumn.
