When receiving the Spear sansevieria plant, do not repot immediately but wait at least 6-12 months. They like to be a bit root-bound. Repot in the spring, using a 2" bigger pot to keep the roots drier. (Too big of a pot could cause the soil to dry slower, which is not helpful.) Use a succulent soilless potting mix with perlite to help with drainage. Place a piece of screening at the bottom of the container over the drainage hole to secure the soil and allow to drain. Use a well-draining cacti and succulent potting mix with perlite to help with drainage. Water your plant in the old pot before transferring over and let sit an hour. Add cacti and succulent soil to the bottom to elevate the root ball. Lift the plant and release the roots against the existing planter. Use a clean knife or garden trowel to wedge between the pot and the soil to loosen. Inspect the roots. Notice if there are any dead or rotting roots and trim off with sterile pruners. Ensure the plant is sitting about 1 inch below the edge of the pot to avoid water spillage. Add more soil and backfill around the sides by tamping down. Fill up to the soil line but not over. Water thoroughly, leaving the soil damp but not soggy. If settling occurs, add more soil. Water well to dampen the soil and let drain.
