How to grow cordon tomatoes

Overview

Growing tomatoes as cordons is the technique of allowing one stem to grow by pinching off side-shoots as they appear. Learn how to raise your cordon crop, in our step-by-step guide.


How to do it

1

Plant young tomatoes into greenhouse borders or growing bags when 20-30cm tall. Heap up the soil around the stem, to encourage more roots to form.


2

Tie in the main stem to a robust cane, to keep it supported. Loop some soft string or twine in a figure of eight around the stem to create a buffer between the two. Don't tie too tightly as the stem will expand as it grows.


3

Check your plants daily, tying them in as they grow. Pinch out any new sideshoots to ensure all of the plant's energy goes into producing flowers and fruit. The sideshoots can be rooted in water and potted up to raise new plants. Remove the growing tip once four flower trusses have formed.


4

As temperatures rise, water your plants whenever you think they need it - daily or every other day, depending on the temperature. Tomatoes benefit from additional feeding; in particular potash (found in specialised tomato feeds) will keep the plants cropping well. Check the label of the tomato feed you buy to see how frequently you should use it.

Has anyone grown the tomato variety Piccolo? Are they only for greenhouses? Can they be grown outside? I bought the seeds, imported from Italy, having tasted them in a supermarket and loved them. I now have four little plants ready to pot on. Would appreciate advice frome someone who has grown them.

Hello Lily. You don't say where you live, which makes it a bit difficult to say.

If you live in the south of England or in a city centre you will have more luck than if you live at the top of a hill in Scotland.

Where are you?

We couldn't find seeds to buy, so grew these last year from seed saved from shop-bought tomatoes. Fantastic crops, both in greenhouse and on the patio. Oh, and we live on the south coast.
