Plug & Liner Overview

Grown to order, plugs and liners are young plants that help you save time, labor, and costs during the production season. Plugs are usually grown from seed while liners are usually grown from cuttings or tissue culture.

Plugs & liners are usually transplanted into packs, pots, or mixed containers for further growing on in a greenhouse. Larger plugs & liners may be transplanted directly into the field for cut flower, vegetable, container, and landscape applications.

Save Time, Labor, And Costs With Plugs & Liners

Quick turnaround time means quick cash. Some trays produce a salable plant in a 4 - 6 inch container in as little as 4 - 6 weeks.

Reduce energy and labor costs related to winter greenhouse production by starting the season with plugs and liners.

Increase variety selection and sales revenue by choosing from thousands of seed and vegetatively-grown annuals, perennials, herbs, and vegetables for bedding plant, container, and cut flower sales.

What Our Customers Think

"The coordination between Harris Seed and Raker-Roberta’s was amazing, and precise, and perfect in every way. I ordered what I wanted, it was seeded and grown, and shipped, and here I have 1,000 tiny begonia plugs (some with flower buds) and 500 angelonia at almost one inch tall ready for cell packs. They arrived moist, well packaged, and in the signature Raker-Roberta’s box. This is a tremendous value for those seeking hard-to-germinate or slow to develop seedlings, like begonia, or expensive seed like angelonia.”
