Poke three to four drainage holes in the bottom with a heated nail.

Fill the base with a layer of small stones, then add a light, well‑draining potting mix.

Plant herbs, succulents, or seedlings, and water sparingly—plastic retains moisture, so over‑watering can cause rot.

Cut 1‑inch‑thick pine strips to frame each pocket, securing with stainless‑steel screws and waterproof wood glue.

Fill the frame with a lightweight soil mix, add a drip‑irrigation line, and plant herbs or small flowers.

This method reuses existing masonry, costs under $30 per pocket, and eliminates the need for freestanding containers.

Finish by attaching simple brackets or a hanging rope for display.

• Use reclaimed wood for the frame to cut costs.
• Seal edges with silicone to prevent leaks.
• Add a drip tray underneath for excess water.
• Rotate the planter monthly for even growth.

DIY Hanging Macramé Pocket Planters – Boho Box‑Style Hanging Solutions

You’ll start by gathering a sturdy piece of natural‑fiber rope, a small wooden or metal frame, and a few cheap fabric or canvas pockets; then, using a simple macramé knot sequence, you’ll weave the rope around the frame to form a hanging “box” that securely holds the pockets for herbs, succulents, or tiny décor items. Cut the rope into equal lengths, tie a square knot at each corner, then create alternating half‑hitches to build the sides.
