Production of plug plants

Walter Bloms Plants Plugs are grown from Unrooted Cuttings planted in peat based compost. The plants are kept in a warm, high humidity area while new roots start to form, after which they are transferred through various cooler temperature regimes that allow the plant to develop a good root system.

Benefits of growing from Plugs

Plugs are a uniform, ready-to-pot product that give rapid, even growth.

When to choose Plugs for your production

3.5cm Plugs are the ideal starting product for growers who want to plant straight into 9cm to 2 litre pots. For pot sizes above 2 litres, we recommend using Jumbo Plugs or Bare Roots, as 3.5cm Plugs will take a long time to fill larger containers.

Ordering timeline

Herbaceous perennial Plugs can normally be delivered from early March until August, depending on the variety and your final goal. For early spring delivery of Vernalised Plugs, we need your order by July the previous year. Unvernalised Plugs can be delivered 8 to 10 weeks after ordering, although longer lead times are advised.

Jumbo Plugs

As the name suggests, Jumbo Plugs are larger versions of regular Plugs. Available in 7cm or 9cm size cells, Jumbo Plugs are a convenient way to obtain young growing plants with better developed root systems.

Walter Blom Plants Bare Root

Bare roots

Herbaceous perennials are defined by the fact that they die back to an underground root system to overwinter. These root systems bulk up over the years, and as they get bigger can be divided to produce new plants, which in turn can be grown on to increase their size.
