Seasonal Container Swaps in a Rock-Mulched Bed

Rock mulch radiates heat and compacts soil, stressing perennials like dianthus. Sinking empty pots into the bed (over weed fabric, under rock) lets you swap annuals seasonally.

Keys to Success

• Pots dry faster—water 2–3× more often than in-ground plants.
• Use quality potting mix with polymer crystals.
• Fertilize regularly (slow-release + liquid).
• Choose heat-tolerant annuals: vinca, pentas, lantana, portulaca, ornamental peppers.

The rock stays; the show changes.
