GROUNDCOVER SPACING CHART
The Plant Spacing Guide will help you calculate how many plants you need
for a space, based on the square footage and your desired spacing.
Please refer to your specified plants’ size and habit to determine ideal spacing.
For example, if you have 100 square feet to cover, with
6” between plants, you will need 400 plants for the job.

Herbaceous Perennial Planting Guidelines
Herbaceous perennials differ from woody perennials when it comes to planting requirements. Here are some guidelines to follow when planting containerized herbaceous perennials.
- The plant crown should be even with the surrounding soil. Herbaceous plants should not be planted high like woody plants are. There are a few exceptions where planting the crown deeper than the surrounding soil is advised. Peonies and Clematis are two examples.
- Loosen surrounding soil at least 3x the root ball width. More is better. If planting a group of plants, loosen the soil in the entire planting area. If the soil is not compacted, loosen the soil slightly deeper than the root ball depth. If the soil is compacted, loosen to below the compacted zone to ensure good drainage. Mix in a high quality compost.
- Container potting soil is not beneficial to the new transplant once in the ground. Remove the lower ¼ to ½ of the root ball and any loose potting soil that can easily be removed without destroying the integrity of the root ball. If highly root bound, cut circling roots on two sides.
- Contour the final grade of the bed to keep water from running off the planting area.
- Mulch planting area with an organic mulch to conserve moisture, control weeds and feed the soil. Reapply as needed.
- Water heavily at planting and regularly until established.
