What Is a Mulflat?

A mulflat is a shallow nursery flat used mainly for low-growing plants that spread across the soil surface.

It is commonly used for:

• Groundcovers
• Spreading perennials
• Low-growing grasses
• Creeping plants
• Mass planting
• Slopes
• Borders

Unlike gallon containers, a mulflat is designed more for coverage and spread than plant height.

How Big Is a Mulflat?

A typical mulflat is approximately:

16" × 16"

Actual dimensions may vary slightly by grower.

The plants are grown together in a shallow flat rather than in individual nursery pots.

How Tall Are Mulflat Plants?

There is no standard height.

Most plants sold in mulflats are relatively low-growing because the format is commonly used for groundcovers and spreading landscape plants.

Actual height depends on:

• Plant variety
• Growth habit
• Age
• Season
• Nursery growing conditions
• Pruning and trimming

Some mulflat plants may only be a few inches tall, while others can be considerably taller.

How Much Area Does One Mulflat Cover?

Coverage depends on the plant variety and how densely you want to plant.

One mulflat can often be divided into multiple sections or individual rooted pieces during installation.

For faster coverage, plant the sections closer together.

For lower cost and more time to fill in, space them farther apart.

Always consider the mature spread of the specific plant.

How Much Does a Mulflat Weigh?

Weight varies by soil moisture, plant variety, root mass, and flat construction.

Most mulflats can be carried by one adult.

A recently watered flat can be noticeably heavier.

Mulflat vs. 1 Gallon Plants

Mulflat

• Designed for broad coverage
• Common for groundcovers
• Can often be divided during planting
• Useful for large planting areas
• Lower profile

1 Gallon

• Individual plant
• Larger root mass per plant
• Easier to count and space
• Better for shrubs, perennials, and individual accent plants

The better choice depends on whether your goal is individual plants or fast area coverage.

When Should You Choose a Mulflat?

Mulflats work especially well for:

• Groundcover installation
• Slopes
• Borders
• Between stepping stones
• Large planting beds
• Erosion-control planting
• Filling open landscape areas

For individual shrubs or larger plants, gallon containers are usually more appropriate.
