• Ideal for borders, edging, containers, pollinator gardens, and foundation plantings.

2. Prepare the Soil

• Loosen soil 8–10 inches deep.
• Incorporate compost or organic matter to improve drainage and fertility.

3. Dig the Hole

• Dig a hole twice as wide as the 3.5" pot and equal depth.

4. Remove from Pot

• Carefully remove the plant from its container.
• Gently loosen any circling roots before planting.

5. Plant

• Position the root ball level with the surrounding soil surface.
• Backfill with soil and gently firm around the roots.

6. Water Thoroughly
