Coated Seed Label: How to Read What the Seed Packet Says
The short answer
A coated seed label tells you the seed carries a thin applied product, often dyed a bright color, and holds its normal size and shape. The packet names any product used and gives handling and storage directions. Read it before you sow and store leftover seed in its labeled packet.
Seed packets carry lots of fine print. Many gardeners skip the note that seed has a coating. Knowing what it means helps you choose the right seed for your garden.
What is coated seed?
Coated seed gets a thin layer of product before packing. The coating sits on the seed surface.
Common coatings help shield seed from soil fungi or insects while it sprouts. They are most often used on large seeds such as corn, peas, beans and squash.
Most coated seed is dyed a bright color such as pink, blue, green or red. The color shows clearly that the seed is not plain seed.
Coated seed sprouts the same way as plain seed. The coating simply sits around it during the first days in the soil.
How do you read a coated seed label?
Seed labels state when seed carries a coating.
Look for these details on the packet.
| Label item | What it tells you |
|---|---|
| Coated seed statement | That seed carries an applied product |
| Product name | Which product was used |
| Handling directions | How to store and sow the seed |
| Germination rate | The share of seeds expected to sprout |
| Lot number | The production lot for that seed |
| Packed for date | The season the seed was packed |

The statement is often printed in a box or in bold on the back of the packet.

How is coated seed different from pelleted seed?
Both are coated, but for different reasons.
Pelleted seed has a thick clay like layer that makes tiny seeds larger and rounder. The University of Illinois Extension article on pelleted seed explains how pellets make small seeds easy to space.
Coated seed has a thin layer of an applied product and holds its normal size and shape.
Some seed is both pelleted and coated. The label tells you which applies.

Sow at the depth listed on the packet. Cover seeds fully with soil.
