How We Send Your Plants

Each of our product pages state how we will dispatch your plants so whether they arrive as bare root plants or plugs you can successfully prepare for their arrival. If you're still a little unsure, take a look at our easy to follow guide below!

Plug Plants

Supplied in our exclusive cartridge plug system, the majority of plug plant deliveries will fit through your letterbox, so your plants are delivered as fresh and healthy as the day they left the nursery.

More about our innovative packaging for our plug plants

Exclusive to Thompson & Morgan, the new cartridge plug system allows us to grow the large bulk of our mail-order plug plants by a method identical to commercial nurseries.

As the young plants grow from seed, they are captured by a camera, which detects any gaps caused by non-germinating or weaker plants. The machine then inserts a fresh plant, a job which was previously done by hand. The benefits that this brings include healthier plants of the highest quality and with in-built strength from a young age.

Our new cartridge plug system provides plants with an extra-strong root system, giving them the best start in life. The new, open sided cartridge causes root tips to dehydrate. This is known as 'air-pruning' which encourages the growth of new, lateral fibrous roots. Up to 10 new fibrous roots can appear, meaning better-rooted, stronger plants than ever before!

The slender plastic packaging and layout of the plants also mean that most packages will sail through modern letterboxes, ensuring they arrive as fresh and healthy as possible.
