Pot sizes explained

At Newlands Nursery we grow and sell plants in a variety of different sizes, from small starter plants up to planted containers. 

We know it can be tricky to picture the size of each plant. This page gives you an idea of the size of the plants we are sending out.

Please keep in mind that plants vary from one season to the next. The size of the plant refers to the pot or plug it is grown in, rather than the height of the plant, unless specifically mentioned on the plant page.

Starter Plant (Plug Plant)

Plug Size: 2cm by 4cm. Our most popular size. This is often the most economical way of buying plants and is a great way to get a head start on the season. Generally this size is best to be potted up before planting out.

Jumbo Plug

Plug Size: 6cm by 7cm. A fantastic alternative to a 9cm pot and saves on plastic too. The plants in this size are well established and give you a head start. This size is perfect for planting straight into containers and baskets as well as the garden.

9cm pot

Pot size: 9cm by 9-10cm. This size hold some well established plants, some of which maybe around 1 year old. We sell most of our ranges in this size and most of the plants sold in this size, are established enough to be planted straight outside.

    Petunia Surfinia Amethyst - Plant information

    Size: Grows to a trailing length of approximately 30-40cm, perfect for hanging baskets and containers. Its spreading habit creates a lush, cascading effect.

    Position: Plant in a sunny spot where it receives plenty of light. It performs best in full sun but tolerates partial shade, making it versatile for various garden locations.

    Feeding etc: Feed with a balanced liquid fertiliser every two weeks during the growing season. Light pruning helps maintain shape and encourages more blooms.

    Care: This petunia is easy to grow and thrives with minimal attention. Water regularly but avoid waterlogging. Deadhead occasionally to encourage prolonged flowering. Ideal for gardeners seeking a low-maintenance, high-impact plant.
