    Our pot & plant size 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.
