Step 1: find a mineral water bottle, cut 1 /3 of the bottle body, and drill the cover.
Step 2: thread a rope through the hole and tie a knot at the end.
Step 3: put the end with the lid and the lower bottle body together, fill the bottle mouth with moist soil, and plant the plant in the soil.
Step 4: pour water into the bottle at the bottom. Don't submerge the cap. The plant can absorb water through the rope.
